Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by urban development and land use change.</big>

== Habitat of the Mule Deer ==
<big>Mule Deer live in a variety of habitats across British Columbia and are a native species to the North American region</big> <ref name=":2" />. <big>In general, vegetation conditions have degraded over time due to increased human activity influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in a given region. Mule Deer also have seasonal habitat needs. If an area meets all their annual needs, then the population will remain, however, most often, Mule Deer will migrate between different habitat areas to meet their seasonal needs. The main reason that drives the need for Mule Deer to seasonally migrate is so that they can seek out thermal cover in the winter, primarily in areas that experience heavy snow fall. Security cover is an important feature that Mule Deer rely on their habitats to provide. Coniferous forest are utilized for their higher snowfall protection and thermal cover whereas deciduous forest provides increased foraging shrubs and debris. Vegetation and landscape features can also be utilized to allow Mule Deer to hide from predators for survival purposes</big> <ref name=":1" />. <big>Overall, habitats play many crucial roles in the location, survival, and health of Mule Deer populations across British Columbia.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts. Researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another and decreasing genetic variability within sub-populations</big> <ref name=":32">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71.</ref>. <big>It is evident that increased connectivity of habitats, either through highway corridors and safe crossings or decreased road density, results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like Mule Deer, require a large area to roam as well as abundant forage and shrubs that are utilized for nutrient intake <ref name=":32" />. Due to these survival needs, food scarcity and habitat fragmentation are seen to be a major threat to the species. Habitat fragmentation can also result in increased energetic costs for Mule Deer <ref name=":1" />. This is because urban development often results in the reduction or complete loss of forest cover which forces Mule Deer populations to travel farther distances in order to fulfill their seasonal needs and receive adequate winter protection. These increased energetic costs can take a harsh toll on the species and lead to dwindling Mule Deer populations</big> <ref name=":1" />.

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present. Urbanization poses a threat to these ideal forage areas since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref name=":8">Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for Mule Deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule Deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high and adequate security is present. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, Mule Deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule Deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time Mule Deer spend at forage areas showing that Mule Deer generally prefer to graze in areas with natural light sources due to their need for security cover from predators. Mule Deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the use of forage areas and the likelihood of Mule Deer crossing roads in comparison to safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to the Mule Deer. This species aims to balance energetic costs with meeting essential needs such as drinking water. If the nearest water source is polluted or if the most suitable habitat has a polluted water source it will still most likely be used. Due to polluted water sources, Mule Deer often have to travel long or steep distances to reach clean water sources which increases their energetic costs, evidently threatening the health of Mule Deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating resulting in increased experiences with human conflict in comparison to non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seeking out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization. Urban Mule Deer do not associate humans with danger like non-urban Mule Deer and, therefore, are more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule Deer in British Columbia is the monitoring of Mule Deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule Deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex and age composition of the total harvested Mule Deer in a given season</big><ref name=":4" /><big>. Mule Deer surveys, such as ground counts or aerial counts, are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule Deer populations, satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule Deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule Deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess Mule Deer survival rates through different periods of migration which found lower survival rates during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule Deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the potential risk of disease spread between Mule Deer populations, health assessments are important to mitigate this risk</big><ref name=":6" /><big>. This conservation technique, along with translocation efforts, can work together to contribute to the successful and safe relocation of Mule Deer in urban regions to non-urban regions, without the risk of harm to either the population being translocated or the pre-established populations.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation which involves moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban Mule Deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer as they tend to travel greater distances after compared to non-urban Mule Deer This is likely because of their willingness to cross roadways and their tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer, it can be a promising conservation strategy for young deer who are not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

=== <big>Wildlife Passages</big> ===
<big>Wildlife agencies in BC are attempting to address the impacts of urbanization on Mule Deer habitats through the construction of safe wildlife passages across highways to connect large areas of habitat</big><ref name=":7">{{Cite journal|last=Chow|first=E|last2=Lamb|first2=C|year=2023|title=Safe Passages for Wildlife in the Southern Canadian Rockies|url=https://a100.gov.bc.ca/pub/acat/documents/r62197/COL_F23_W_3733_1693942315365_0659A0EF53.pdf|journal=Fish and Wildlife Compensation Program|publisher=BC Government}}</ref><big>. This management action address both the loss of habitat connectivity and high mortality of Mule Deer from vehicle collisions. In addition, safeguarding measures like fencing are being constructed to further reduce access wildlife have to crossing highways</big><ref name=":7" /><big>. This conservation effort has reduced wildlife-vehicle collisions by over 80% in some areas of BC, Mule Deer being one of the most frequent species captured on trail cameras in the underpasses</big><ref name=":7" /><big>. This type of intervention is especially beneficial for Mule Deer seeing as they tend to cross highways most frequently due to their need to migrate long distances for sufficient winter and summer forage</big><ref name=":8" /><big>. Overall, implementing safe wildlife passages around high-traffic crossing areas is a simple and effective method to address the impacts of urbanization on Mule Deer</big> <ref name=":7" /><big>. Seeing as habitat fragmentation is one of the most significant impacts of urbanization on Mule Deer as well as how the desensitization of Mule Deer to human activity has led to increased crossing of roadways this conservation effort is multifaceted in it's approach addressing multiple issues simultaneously</big><ref name=":7" /><big>. Additionally, there are mutual benefits derived from having fewer Deer crossing highways since drivers will have fewer dangerous encounters with Deer on the road.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres</big> <ref name=":2" />. <big>It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government</big><ref name=":2" /><big>.</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

Mule Deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the use of forage areas and the likelihood of Mule Deer crossing roads in comparison to safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to the Mule Deer. This species aims to balance energetic costs with meeting essential needs such as drinking water. If the nearest water source is polluted or if the most suitable habitat has a polluted water source it will still most likely be used. Due to polluted water sources, Mule Deer often have to travel long or steep distances to reach clean water sources which increases their energetic costs, evidently threatening the health of Mule Deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating resulting in increased experiences with human conflict in comparison to non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seeking out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization. Urban Mule Deer do not associate humans with danger like non-urban Mule Deer and, therefore, are more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule Deer in British Columbia is the monitoring of Mule Deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule Deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex and age composition of the total harvested Mule Deer in a given season</big><ref name=":4" /><big>. Mule Deer surveys, such as ground counts or aerial counts, are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule Deer populations, satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule Deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule Deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess Mule Deer survival rates through different periods of migration which found lower survival rates during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule Deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the potential risk of disease spread between Mule Deer populations, health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation which involves moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban Mule Deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer as they tend to travel greater distances after compared to non-urban Mule Deer This is likely because of their willingness to cross roadways and their tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer, it can be a promising conservation strategy for young deer who are not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

=== <big>Wildlife Passages</big> ===
<big>Wildlife agencies in BC are attempting to address the impacts of urbanization on Mule Deer habitats through the construction of safe wildlife passages across highways to connect large areas of habitat</big><ref name=":7">{{Cite journal|last=Chow|first=E|last2=Lamb|first2=C|year=2023|title=Safe Passages for Wildlife in the Southern Canadian Rockies|url=https://a100.gov.bc.ca/pub/acat/documents/r62197/COL_F23_W_3733_1693942315365_0659A0EF53.pdf|journal=Fish and Wildlife Compensation Program|publisher=BC Government}}</ref><big>. This management action address both the loss of habitat connectivity and high mortality of Mule Deer from vehicle collisions. In addition, safeguarding measures like fencing are being constructed to further reduce access wildlife have to crossing highways</big><ref name=":7" /><big>. This conservation effort has reduced wildlife-vehicle collisions by over 80% in some areas of BC, Mule Deer being one of the most frequent species captured on trail cameras in the underpasses</big><ref name=":7" /><big>. This type of intervention is especially beneficial for Mule Deer seeing as they tend to cross highways most frequently due to their need to migrate long distances for sufficient winter and summer forage</big><ref name=":8" /><big>. Overall, implementing safe wildlife passages around high-traffic crossing areas is a simple and effective method to address the impacts of urbanization on Mule Deer</big> <ref name=":7" /><big>. Seeing as habitat fragmentation is one of the most significant impacts of urbanization on Mule Deer as well as how the desensitization of Mule Deer to human activity has led to increased crossing of roadways this conservation effort is multifaceted in it's approach addressing multiple issues simultaneously</big><ref name=":7" /><big>. Additionally, there are mutual benefits derived from having fewer Deer crossing highways since drivers will have fewer dangerous encounters with Deer on the road.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres</big> <ref name=":2" />. <big>It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government</big><ref name=":2" /><big>.</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-13T01:52:43Z

KatelynPutz: /* Habitat Fragmentation */

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025). [https://www.sciencedirect.com/science/article/pii/S1462901125001522 Reconciling wildlife governance in a changing climate: A systematic review of mule deer management in St’át’imc Territory.] ''Environmental Science & Policy'', ''171'', 104136.</ref><big>. Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall</big> <big>Light pollution that is produced from increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by urban development and land use change.</big>

== Habitat of the Mule Deer ==
<big>Mule Deer live in a variety of habitats across British Columbia and are a native species to the North American region</big> <ref name=":2" />. <big>In general, vegetation conditions have degraded over time due to increased human activity influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in a given region. Mule Deer also have seasonal habitat needs. If an area meets all their annual needs, then the population will remain, however, most often, Mule Deer will migrate between different habitat areas to meet their seasonal needs. The main reason that drives the need for Mule Deer to seasonally migrate is so that they can seek out thermal cover in the winter, primarily in areas that experience heavy snow fall. Security cover is an important feature that Mule Deer rely on their habitats to provide. Coniferous forest are utilized for their higher snowfall protection and thermal cover whereas deciduous forest provides increased foraging shrubs and debris. Vegetation and landscape features can also be utilized to allow Mule Deer to hide from predators for survival purposes</big> <ref name=":1" />. <big>Overall, habitats play many crucial roles in the location, survival, and health of Mule Deer populations across British Columbia.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts. Researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another and decreasing genetic variability within sub-populations</big> <ref name=":32">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71.</ref>. <big>It is evident that increased connectivity of habitats, either through highway corridors and safe crossings or decreased road density, results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like Mule Deer, require a large area to roam as well as abundant forage and shrubs that are utilized for nutrient intake. Due to these survival needs, food scarcity and habitat fragmentation are seen to be a major threat to the species. Habitat fragmentation can also result in increased energetic costs for Mule Deer. This is because urban development often results in the reduction or complete loss of forest cover which forces Mule Deer populations to travel farther distances in order to fulfill their seasonal needs and receive adequate winter protection. These increased energetic costs can take a harsh toll on the species and lead to dwindling Mule Deer populations</big> <ref name=":1" />.

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present. Urbanization poses a threat to these ideal forage areas since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for Mule Deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule Deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high and adequate security is present. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, Mule Deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule Deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time Mule Deer spend at forage areas showing that Mule Deer generally prefer to graze in areas with natural light sources due to their need for security cover from predators. Mule Deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the use of forage areas and the likelihood of Mule Deer crossing roads in comparison to safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to the Mule Deer. This species aims to balance energetic costs with meeting essential needs such as drinking water. If the nearest water source is polluted or if the most suitable habitat has a polluted water source it will still most likely be used. Due to polluted water sources, Mule Deer often have to travel long or steep distances to reach clean water sources which increases their energetic costs, evidently threatening the health of Mule Deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating resulting in increased experiences with human conflict in comparison to non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seeking out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule Deer in British Columbia is the monitoring of Mule Deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I.

'''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule Deer populations</big> <ref name=":4" /><big>.

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule Deer populations, satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule Deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C.

This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule Deer in BC</big> <ref name=":5" /><big>.

=== <big>Wildlife Passages</big> ===
<big>Wildlife agencies in BC are attempting to address the impacts of urbanization on Mule Deer habitats through the construction of safe wildlife passages across highways to connect large areas of habitat</big><ref name=":7">{{Cite journal|last=Chow|first=E|last2=Lamb|first2=C|year=2023|title=Safe Passages for Wildlife in the Southern Canadian Rockies|url=https://a100.gov.bc.ca/pub/acat/documents/r62197/COL_F23_W_3733_1693942315365_0659A0EF53.pdf|journal=Fish and Wildlife Compensation Program|publisher=BC Government}}</ref><big>.

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres</big> <ref name=":2" />. <big>It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government</big><ref name=":2" /><big>.</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-13T01:50:28Z

KatelynPutz: /* Habitat Fragmentation */

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020).

Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall</big> <big>Light pollution that is produced from increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by urban development and land use change.</big>

== Habitat of the Mule Deer ==
<big>Mule Deer live in a variety of habitats across British Columbia and are a native species to the North American region. In general, vegetation conditions have degraded over time due to increased human activity influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in a given region. Mule Deer also have seasonal habitat needs. If an area meets all their annual needs, then the population will remain, however, most often, Mule Deer will migrate between different habitat areas to meet their seasonal needs. The main reason that drives the need for Mule Deer to seasonally migrate is so that they can seek out thermal cover in the winter, primarily in areas that experience heavy snow fall. Security cover is an important feature that Mule Deer rely on their habitats to provide. Coniferous forest are utilized for their higher snowfall protection and thermal cover whereas deciduous forest provides increased foraging shrubs and debris. Vegetation and landscape features can also be utilized to allow Mule Deer to hide from predators for survival purposes</big> <ref name=":1" />. <big>Overall, habitats play many crucial roles in the location, survival, and health of Mule Deer populations across British Columbia.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts. Researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another and decreasing genetic variability within sub-populations . It is evident that increased connectivity of habitats, either through highway corridors and safe crossings or decreased road density, results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like Mule Deer, require a large area to roam as well as abundant forage and shrubs that are utilized for nutrient intake. Due to these survival needs, food scarcity and habitat fragmentation are seen to be a major threat to the species. Habitat fragmentation can also result in increased energetic costs for Mule Deer. This is because urban development often results in the reduction or complete loss of forest cover which forces Mule Deer populations to travel farther distances in order to fulfill their seasonal needs and receive adequate winter protection. These increased energetic costs can take a harsh toll on the species and lead to dwindling Mule Deer populations</big> <ref name=":1" />.

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present. Urbanization poses a threat to these ideal forage areas since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for Mule Deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule Deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high and adequate security is present. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, Mule Deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule Deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time Mule Deer spend at forage areas showing that Mule Deer generally prefer to graze in areas with natural light sources due to their need for security cover from predators. Mule Deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the use of forage areas and the likelihood of Mule Deer crossing roads in comparison to safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to the Mule Deer. This species aims to balance energetic costs with meeting essential needs such as drinking water. If the nearest water source is polluted or if the most suitable habitat has a polluted water source it will still most likely be used. Due to polluted water sources, Mule Deer often have to travel long or steep distances to reach clean water sources which increases their energetic costs, evidently threatening the health of Mule Deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating resulting in increased experiences with human conflict in comparison to non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seeking out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization. Urban Mule Deer do not associate humans with danger like non-urban Mule Deer and, therefore, are more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule Deer in British Columbia is the monitoring of Mule Deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule Deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex and age composition of the total harvested Mule Deer in a given season</big><ref name=":4" /><big>. Mule Deer surveys, such as ground counts or aerial counts, are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule Deer populations, satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule Deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule Deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess Mule Deer survival rates through different periods of migration which found lower survival rates during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule Deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the potential risk of disease spread between Mule Deer populations, health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation which involves moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban Mule Deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer as they tend to travel greater distances after compared to non-urban Mule Deer This is likely because of their willingness to cross roadways and their tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer, it can be a promising conservation strategy for young deer who are not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

=== <big>Wildlife Passages</big> ===
<big>Wildlife agencies in BC are attempting to address the impacts of urbanization on Mule Deer habitats through the construction of safe wildlife passages across highways to connect large areas of habitat</big><ref name=":7">{{Cite journal|last=Chow|first=E|last2=Lamb|first2=C|year=2023|title=Safe Passages for Wildlife in the Southern Canadian Rockies|url=https://a100.gov.bc.ca/pub/acat/documents/r62197/COL_F23_W_3733_1693942315365_0659A0EF53.pdf|journal=Fish and Wildlife Compensation Program|publisher=BC Government}}</ref><big>. In addition, safeguarding measures like fencing are being constructed to further reduce the number of wildlife mortality around highways</big><ref name=":7" /><big>. This conservation effort has reduced wildlife-vehicle collisions by over 80% in some areas of BC, Mule Deer being one of the most frequent species captured on trail cameras in the underpasses</big><ref name=":7" /><big>. Overall, implementing safe wildlife passages around high-traffic crossing areas is a simple and effective method to address Mule Deer habitat fragmentation</big><ref name=":7" /><big>. Not to mention the mutual benefits drivers derive from having fewer Deer crossing highways.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>. It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government</big><ref name=":2" /><big>.</big>

[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1.

The ideal forage for Mule Deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule Deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high and adequate security is present. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, Mule Deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule Deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time Mule Deer spend at forage areas showing that Mule Deer generally prefer to graze in areas with natural light sources due to their need for security cover from predators. Mule Deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the use of forage areas and the likelihood of Mule Deer crossing roads in comparison to safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to the Mule Deer. This species aims to balance energetic costs with meeting essential needs such as drinking water. If the nearest water source is polluted or if the most suitable habitat has a polluted water source it will still most likely be used. Due to polluted water sources, Mule Deer often have to travel long or steep distances to reach clean water sources which increases their energetic costs, evidently threatening the health of Mule Deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating resulting in increased experiences with human conflict in comparison to non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seeking out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization. Urban Mule Deer do not associate humans with danger like non-urban Mule Deer and, therefore, are more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule Deer in British Columbia is the monitoring of Mule Deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule Deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex and age composition of the total harvested Mule Deer in a given season</big><ref name=":4" /><big>. Mule Deer surveys, such as ground counts or aerial counts, are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule Deer populations, satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule Deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule Deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess Mule Deer survival rates through different periods of migration which found lower survival rates during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule Deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the potential risk of disease spread between Mule Deer populations, health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation which involves moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban Mule Deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer as they tend to travel greater distances after compared to non-urban Mule Deer This is likely because of their willingness to cross roadways and their tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer, it can be a promising conservation strategy for young deer who are not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>. It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government</big><ref name=":2" /><big>.</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-13T00:58:55Z

KatelynPutz: /* Habitat of the Mule Deer */

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025).

Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by urban development and land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule Deer also have seasonal habitat needs. If an area meets all annual needs the population will remain however, most often, Mule Deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats. Vegetation or landscape features are utilized to allow Mule Deer to hide from predators for survival purposes</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like Mule Deer, require a large area to roam as well as abundant forage and shrubs that are utilized for nutrient intake. Due to these survival needs, food scarcity and habitat fragmentation are seen to be a major threat to the species. Habitat fragmentation can also result in increased energetic costs for mule deer if they have to travel farther distances to meet seasonal needs or if adequate thermal cover is not available in the winter. These increased energetic costs can lead to dwindling Mule Deer populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present. Urbanization poses a threat to these ideal forage areas since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E.

=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-13T00:43:19Z

KatelynPutz: /* Predation */

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025).

Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by urban development and land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule Deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often, Mule Deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats. Vegetation or landscape features are utilized to allow Mule Deer to hide from predators for survival purposes</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like Mule Deer, require a large area to roam as well as abundant forage and shrubs that are utilized for nutrient intake. Due to these survival needs, food scarcity and habitat fragmentation are seen to be a major threat to the species. Habitat fragmentation can also result in increased energetic costs for mule deer if they have to travel farther distances to meet seasonal needs or if adequate thermal cover is not available in the winter. These increased energetic costs can lead to dwindling Mule Deer populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present. Urbanization poses a threat to these ideal forage areas since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for Mule Deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule Deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high and adequate security is present. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, Mule Deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule Deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time Mule Deer spend at forage areas showing that Mule Deer generally prefer to graze in areas with natural light sources due to their need for security cover from predators. Mule Deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the use of forage areas and the likelihood of Mule Deer crossing roads in comparison to safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to the Mule Deer. This species aims to balance energetic costs with meeting essential needs such as drinking water. If the nearest water source is polluted or if the most suitable habitat has a polluted water source it will still most likely be used. Due to polluted water sources, Mule Deer often have to travel long or steep distances to reach clean water sources which increases their energetic costs, evidently threatening the health of Mule Deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating resulting in increased experiences with human conflict in comparison to non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seeking out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization. Urban Mule Deer do not associate humans with danger like non-urban Mule Deer and, therefore, are more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule Deer in British Columbia is the monitoring of Mule Deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule Deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex and age composition of the total harvested Mule Deer in a given season</big><ref name=":4" /><big>. Mule Deer surveys, such as ground counts or aerial counts, are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule Deer populations, satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule Deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule Deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess Mule Deer survival rates through different periods of migration which found lower survival rates during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule Deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the potential risk of disease spread between Mule Deer populations, health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation which involves moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban Mule Deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer as they tend to travel greater distances after compared to non-urban Mule Deer This is likely because of their willingness to cross roadways and their tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer, it can be a promising conservation strategy for young deer who are not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>.

Artificial light is also observed to shorten the time Mule Deer spend at forage areas showing that Mule Deer generally prefer to graze in areas with natural light sources due to their need for security cover from predators. Mule Deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the use of forage areas and the likelihood of Mule Deer crossing roads in comparison to safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to the Mule Deer. This species aims to balance energetic costs with meeting essential needs such as drinking water. If the nearest water source is polluted or if the most suitable habitat has a polluted water source it will still most likely be used. Due to polluted water sources, Mule Deer often have to travel long or steep distances to reach clean water sources which increases their energetic costs, evidently threatening the health of Mule Deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating resulting in increased experiences with human conflict in comparison to non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seeking out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization. Urban Mule Deer do not associate humans with danger like non-urban Mule Deer and, therefore, are more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule deer in British Columbia is the monitoring of Mule deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex/age composition of the total harvested Mule deer in a given season</big><ref name=":4" /><big>. Mule deer surveys such as ground counts or aerial counts are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule deer populations satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess mule deer survival rates through different periods of migration, finding a lower survival rate during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the risk of disease spread between Mule Deer populations health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation, moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban mule deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer they tend to travel greater distances after release than non-urban Mule Deer, likely because of their willingness to cross roadways and tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer it can be a promising conservation strategy for young deer not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>. It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government</big><ref name=":2" /><big>.</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-13T00:29:39Z

KatelynPutz: /* Habitat Fragmentation */

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025).

Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by urban development and land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule Deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often, Mule Deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats. Vegetation or landscape features are utilized to allow Mule Deer to hide from predators for survival purposes</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like Mule Deer, require a large area to roam as well as abundant forage and shrubs that are utilized for nutrient intake. Due to these survival needs, food scarcity and habitat fragmentation are seen to be a major threat to the species. Habitat fragmentation can also result in increased energetic costs for mule deer if they have to travel farther distances to meet seasonal needs or if adequate thermal cover is not available in the winter. These increased energetic costs can lead to dwindling Mule Deer populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present. Urbanization poses a threat to these ideal forage areas since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for Mule Deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule Deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high and adequate security is present. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, Mule Deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule Deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023).

'''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations</big> <ref name=":3" /><big>.</big>

Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025).

Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by urban development and land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule Deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often, Mule Deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats. Vegetation or landscape features are utilized to allow Mule Deer to hide from predators for survival purposes</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on Mule Deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like Mule Deer, require a large area to roam as well as abundant forage and shrubs that are utilized for nutrient intake. Due herefore, food scarcity and habitat fragmentation are seen to be a major threat. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating, experiencing increased human conflict in comparison with non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seek out natural habitats for winter forage</big> <ref name=":1" /><big>. Though human effort has been put in to create overpasses to aid in wildlife movement and migration, Mule Deer have been found to avoid overpasses close to areas were human impact has increased</big><ref>{{Cite journal|last=Hamilton|first=Kaela M.|last2=Bommarito|first2=Thomas|last3=Lewis|first3=Jesse S.|date=February 2024|title=Human activities influence mule deer use of overpasses across multiple scales|url=https://doi.org/10.1002/jwmg.22560|journal=The Journal of Wildlife Management}}</ref><big>.Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization, Urban Mule Deer do not associate humans with danger like non-urban mule deer and therefore and more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule deer in British Columbia is the monitoring of Mule deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex/age composition of the total harvested Mule deer in a given season</big><ref name=":4" /><big>. Mule deer surveys such as ground counts or aerial counts are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule deer populations satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess mule deer survival rates through different periods of migration, finding a lower survival rate during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the risk of disease spread between Mule Deer populations health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation, moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban mule deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer they tend to travel greater distances after release than non-urban Mule Deer, likely because of their willingness to cross roadways and tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer it can be a promising conservation strategy for young deer not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>. It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government</big><ref name=":2" /><big>.</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E.

The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs.

Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G.

'''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023).

'''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating, experiencing increased human conflict in comparison with non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seek out natural habitats for winter forage</big> <ref name=":1" /><big>.

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule deer in British Columbia is the monitoring of Mule deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017).

'''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex/age composition of the total harvested Mule deer in a given season</big><ref name=":4" /><big>. Mule deer surveys such as ground counts or aerial counts are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule deer populations satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess mule deer survival rates through different periods of migration, finding a lower survival rate during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the risk of disease spread between Mule Deer populations health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation, moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban mule deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer they tend to travel greater distances after release than non-urban Mule Deer, likely because of their willingness to cross roadways and tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer it can be a promising conservation strategy for young deer not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>. It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government (9).</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions<ref name=":1" /></big>. <big>Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before the translocation of urban Mule Deer can occur<ref name=":1" />.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-12T20:59:36Z

KatelynPutz: /* Habitat Evaluation */

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025). [https://www.sciencedirect.com/science/article/pii/S1462901125001522 Reconciling wildlife governance in a changing climate: A systematic review of mule deer management in St’át’imc Territory.] ''Environmental Science & Policy'', ''171'', 104136.</ref><big>. Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from the increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating, experiencing increased human conflict in comparison with non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seek out natural habitats for winter forage</big> <ref name=":1" /><big>. Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization, Urban Mule Deer do not associate humans with danger like non-urban mule deer and therefore and more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule deer in British Columbia is the monitoring of Mule deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex/age composition of the total harvested Mule deer in a given season</big><ref name=":4" /><big>. Mule deer surveys such as ground counts or aerial counts are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule deer populations satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess mule deer survival rates through different periods of migration, finding a lower survival rate during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the risk of disease spread between Mule Deer populations health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation, moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban mule deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer they tend to travel greater distances after release than non-urban Mule Deer, likely because of their willingness to cross roadways and tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer it can be a promising conservation strategy for young deer not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>.

This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>.

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing.

<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating, experiencing increased human conflict in comparison with non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seek out natural habitats for winter forage</big> <ref name=":1" /><big>. Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization, Urban Mule Deer do not associate humans with danger like non-urban mule deer and therefore and more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule deer in British Columbia is the monitoring of Mule deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex/age composition of the total harvested Mule deer in a given season</big><ref name=":4" /><big>. Mule deer surveys such as ground counts or aerial counts are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule deer populations satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule deer in BC</big> <ref name=":5" /><big>. Radio collar tracking has been used in eastern Oregon, USA to assess mule deer survival rates through different periods of migration, finding a lower survival rate during fall migration</big><ref>{{Cite journal|last=Schuyler|first=Elizabeth M.|last2=Dugger|first2=Katie M.|last3=Jackson|first3=Dewaine H.|date=August 2018|title=Effects of distribution, behavior, and climate on mule deer survival|url=https://doi.org/10.1002/jwmg.21558|journal=The Journal Of Wildlife Management}}</ref>.

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates</big><ref name=":6">{{Cite journal|last=Mathieu|first=A|last2=Flint|first2=M|last3=Stent|first3=P|last4=Schwantje|first4=M|last5=Wittum|first5=E|title=Comparative health assessment of urban and non-urban free-ranging mule deer (Odocoileus hemionus) in southeastern British Columbia, Canada|url=https://doi.org/10.7717/peerj.4968|journal=ProQuest|publisher=PeerJ|publication-date=2018}}</ref><big>. Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area</big><ref name=":6" /><big>. Since translocation poses the risk of disease spread between Mule Deer populations health assessments are important to mitigate this risk</big><ref name=":6" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation, moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban mule deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer they tend to travel greater distances after release than non-urban Mule Deer, likely because of their willingness to cross roadways and tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer it can be a promising conservation strategy for young deer not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>. It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government (9).</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>. Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>. Another management strategy includes the translocation of urban deer to non-urban regions (1). Habitat evaluation is a crucial component to the success of this conservation management strategy because the region in which the urban deer are translocated to is dependent on pre-existing non-urban deer populations. To ensure no diseases are spread from the urban population to the non-urban population, habitat location is required to be assessed before translocation of the urban Mule Deer (1).</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>.

Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from the increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===

<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1.

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>.

Improving available forage is a more natural approach that enables Mule Deer populations to reestablish long term residency in habitats that have adequate foraging ground and natural fresh water sources.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-12T20:35:31Z

KatelynPutz:

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025). [https://www.sciencedirect.com/science/article/pii/S1462901125001522 Reconciling wildlife governance in a changing climate: A systematic review of mule deer management in St’át’imc Territory.] ''Environmental Science & Policy'', ''171'', 104136.</ref><big>. Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). [https://doi.org/10.5558/tfc68132-1 Logging on mule deer winter range: An integrated management approach.] ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from the increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). [https://link.springer.com/article/10.1007/s10980-019-00824-9 Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape.] ''Landscape Ecology '''34.''''' 1097–1115. </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). [https://www.taylorfrancis.com/reader/download/557aa028-9851-432b-ab0e-698c90abd41f/chapter/pdf?context=ubx Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America.] ''Boca Raton.''</ref><big>. The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).[https://www.sciencedirect.com/science/article/pii/S0378112708003897 The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem.] ''Forest Ecology and Management.'' '''256(3), 452–461. ''' </ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). [https://www.sciencedirect.com/science/article/pii/S1439179123000592 Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity.] ''Basic and Applied Ecology''. '''73,''' 62-71. </ref><big>. Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating, experiencing increased human conflict in comparison with non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seek out natural habitats for winter forage</big> <ref name=":1" /><big>. Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization, Urban Mule Deer do not associate humans with danger like non-urban mule deer and therefore and more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule deer in British Columbia is the monitoring of Mule deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). [https://doi.org/10.1002/wsb.781 An integrated modeling approach for assessing management objectives for mule deer in central British Columbia.] ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex/age composition of the total harvested Mule deer in a given season</big><ref name=":4" /><big>. Mule deer surveys such as ground counts or aerial counts are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule deer populations satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). [https://a100.gov.bc.ca/pub/acat/documents/r43745/13WBRG02_Mule_D_1411408436133_1406712679.pdf Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia.] </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule deer in BC</big> <ref name=":5" /><big>.</big>

=== <big>Population Monitoring - Health Assessments</big> ===
<big>While health assessments of Mule Deer in BC are not frequent, they are performed occasionally to determine the health impacts and efficacy of other ongoing conservation efforts such as translocation. Health assessments for Mule deer consist of taking blood samples from a variety of individuals in a Mule Deer population to determine the prevalence of disease and pregnancy rates(6). Health assessments aid wildlife agencies in determining how effective translocation efforts have been and capture the overall prevalence of disease in an area(6). Since translocation poses the risk of disease spread between Mule Deer populations health assessments are important to mitigate this risk(6).</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation, moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban mule deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer they tend to travel greater distances after release than non-urban Mule Deer, likely because of their willingness to cross roadways and tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer it can be a promising conservation strategy for young deer not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
[[File:Pexels-james-mirakian-774977502-30905113.jpg|thumb|Mule Deer (Odocoileus hemionus) fawn and doe]]
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land</big><ref name=":2" /><big>. Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres<ref name=":2" /></big><big>. It has been acknowledged that more robust policies and legislation need to be developed in order to ensure equally weighted and regulated conservation management efforts between Indigenous communities and the Provincial Government (9).</big>
=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Habitat fragmentation majorly impacts non-urban Mule Deer's ability to forage and find adequate shelter, especially for populations that reside in areas with harsh winter conditions. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas. An example of protected area use in British Columbia comes from members of the St'át'imc territory who have proposed the idea of implementing protected areas that focus specifically on Mule Deer fawning zones</big> <ref name=":2" /><big>. This would focus on supporting the Mule Deer species while also engaging with Indigenous communities in British Columbia to implement conservation practices.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>. Additionally, improving the forage available for Mule Deer near naturally occurring water sources aids in lowering the energetic costs while resolving water availability issues simultaneously</big><ref name=":1" /><big>.</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer</big><ref name=":1" /><big>. This approach aims to identify which key components of a Mule Deer habitat are missing to efficiently improve the habitat to an ideal state</big><ref name=":1" /><big>. Consequently, this approach reduces stress on Mule Deer populations by aiming to increase the abundance of ideal habitat areas</big><ref name=":1" /><big>.</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

=== <big>Protecting Habitats</big> ===
<big>One of the more prominent solutions would be to avoid disrupting corridors and terrain that are used by mule deer to access foraging areas when developing infrastructure</big> <ref name=":1" /><big>. Aside from just limiting habitat disruption, it is also important to manage and offset the impacts that do occur through rehabilitation efforts and protected areas.

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss and fragmentation, food insecurity, and increased pollution. Habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Light pollution, produced from urban centres, and water pollution are also issues the Mule Deer in British Columbia are currently facing. Mitigation efforts such as adopting Indigenous Land practice conservation techniques, habitat protection, increasing water availability, and habitat evaluations are all crucial steps in supporting the health and well being of the Mule Deer species. Overall, continued monitoring of the Mule Deer's is necessary to better understand and mitigate the ways in which they are impacted by growing Urbanization across British Columbia. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-12T20:23:07Z

KatelynPutz: /* Indigenous Land Management Practices */

== Introduction ==
[[File:Odocoileus hemionus in BC, Canada 07.JPG|thumb|350x350px|Mule Deer (Odocoileus hemionus) in British Columbia Canada ]]
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research</big> <ref name=":1">Wright, C. A., Adams, I. T., Stent, P., & Ford, A. T. (2020). [https://doi.org/10.1002/jwmg.21935 Comparing Survival and Movements of Non-Urban and Urban Translocated Mule Deer.] ''The Journal of Wildlife Management.'' '''84(8'''), 1457–1472.</ref><big>. Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America</big> <ref name=":2">Andrascik, N., & Grenz, J. (2025). Reconciling wildlife governance in a changing climate: A systematic review of mule deer management in St’át’imc Territory. ''Environmental Science & Policy'', ''171'', 104136.</ref><big>. Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia</big> <ref name=":2" /><big>. Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres</big> <ref name=":0">Armleder, H. M., & Dawson, R. J. (February 1992). Logging on mule deer winter range: An integrated management approach. ''The Forestry Chronicle.'' '''68.'''</ref><big>. Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from the increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available</big> <ref name=":0" /><big>. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred</big> <ref name=":1" /><big>.</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
[[File:8043741657 c6960091f3 b.jpg|thumb|322x322px|Mule Deer (Odocoileus Hemionus) crossing a road]]
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations</big> <ref>'''1. '''Fraser, D.L., Ironside, K., Wayne, R.K. et al (2019). Connectivity of mule deer (Odocoileus hemionus) populations in a highly fragmented urban landscape. ''Landscape Ecology '''34.''''' '''1097–1115.''' </ref><big>. It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations</big> <ref name=":1" /><big>.</big>
=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas</big> <ref>Arnett, E. B., Belinda, S. R., Gray, S. S., Ielmini, M., Logan, B., Pieron, M., Tator, I. (2023). Threats to Habitat Function. In Ecology and Management of Black-Tailed and Mule Deer of North America. ''Boca Raton.''</ref><big>. The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce</big> <ref name=":0" /><big>. Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover</big> <ref>Serrouya, R., & D’Eon, R. G. (2008).The influence of forest cover on mule deer habitat selection, diet, and nutritiProcter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia. on during winter in a deep-snow ecosystem. ''Forest Ecology and Management.'''''256(3), 452–461.'''</ref><big>. Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density</big> <ref name=":3">Ditmer, M. A., Carter, N. H., Hersey, K. R., Leclerc, M., Wittemyer, G., Stoner, D. C. (2023). Navigating the wildland-urban interface: Sensory pollution and infrastructure effects on mule deer behavior and connectivity. ''Basic and Applied Ecology''. '''73, 62, 71'''. </ref><big>. Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors</big> <ref name=":3" /><big>. Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations</big> <ref name=":3" /><big>.</big>

== Impacts of Urbanization on Mule Deer Behaviour ==

=== <big>Migration</big> ===
<big>Urban Mule Deer that have become comfortable around human behaviour tend to cross roadways more willingly when migrating, experiencing increased human conflict in comparison with non-urban Mule Deer</big><ref name=":1" /><big>. Additionally, due to urban Mule Deer's comfort level in urban settings, they tend to migrate from town to town rather than seek out natural habitats for winter forage</big> <ref name=":1" /><big>. Generally, urban Mule Deer experience higher levels of human conflict and incur higher energetic costs when forced to migrate due to their desensitization to urban settings.</big>

=== <big>Predation</big> ===
<big>It is especially evident through translocation efforts in BC, that urban Mule Deer experience higher level of predation than non-urban Mule Deer</big> <ref name=":1" /><big>. This susceptibility to predation is attributed to human desensitization, Urban Mule Deer do not associate humans with danger like non-urban mule deer and therefore and more likely to be killed by hunters and be hit by vehicles while crossing highways</big> <ref name=":1" /><big>. Furthermore, translocation studies have found that urban Mule Deer being unfamiliar with natural habitats reduces their evasion ability when being hunted, subsequently experiencing lower survival rates in comparison to non-urban Mule Deer</big> <ref name=":1" /><big>.</big>

== Current Conservation Efforts ==

=== <big>Population Monitoring - Surveys & Modelling</big> ===
<big>One of the primary conservation efforts for the Mule deer in British Columbia is the monitoring of Mule deer population sizes. The estimation of population sizes informs wildlife agencies on how they can adjust the availability of hunting permits appropriately to meet post-hunting season population targets</big> <ref name=":4">Hatter, I. W., Dielman, P., & Kuzyk, G. W. (2017). An integrated modeling approach for assessing management objectives for mule deer in central British Columbia. ''Wildlife Society Bulletin. '''41'''''<nowiki/>'''(3), 508–515.'''</ref><big>. These targets can vary; most often, it is a post-hunt population size or density or even an adult sex ratio that would ensure the conservation of Mule deer populations</big> <ref name=":4" /><big>. A variety of techniques can be used for population estimates. Hunter harvest surveys are used to capture the sex/age composition of the total harvested Mule deer in a given season</big><ref name=":4" /><big>. Mule deer surveys such as ground counts or aerial counts are used in the spring and autumn to capture general abundance or density</big> <ref name=":4" /><big>. Given the information gathered regarding abundance, density and composition, population models can be applied to better understand the likely population sizes and inform decisions about the next hunting season</big> <ref name=":4" /><big>.</big>

=== <big>Population Monitoring - Collar Tracking</big> ===
<big>For more extensive information on Mule deer populations satellite collars are often utilized. Collared deer can be tracked generating data on the spatial distribution of Mule deer populations</big> <ref name=":5">Procter, C., Iredale, F., Jury, D., Manual, M., Council, L., & Lillooet, B. C. (2014). Mule Deer Buck Migrations and Habitat Use in the Bridge River, British Columbia. </ref><big>. This also allows wildlife agencies to understand survival rates and estimate the range of Mule deer populations</big> <ref name=":5" /><big>. The acquisition of this data informs stakeholders of the efficacy of current management actions, the accuracy of population models used in estimation and migratory patterns of Mule deer in BC</big> <ref name=":5" /><big>.</big>

=== <big>Translocation</big> ===
<big>To address the negative impacts of urbanization on Mule Deer in BC, wildlife agencies have also used translocation, moving Mule Deer away from urban settings</big><ref name=":1" /><big>. However, Mule Deer that are familiar with urban settings have been observed to no longer associate humans with danger</big><ref name=":1" /><big>. Consequently, when Mule deer are translocated from urban settings, they are more likely to be killed by hunters than non-urban mule deer, as they are desensitized to human presence</big><ref name=":1" /><big>. Unfamiliarity with release sites can also impact the survival of translocated urban Mule Deer they tend to travel greater distances after release than non-urban Mule Deer, likely because of their willingness to cross roadways and tendency to return to nearby municipalities</big><ref name=":1" /><big>. Although translocation poses many challenges affecting the survival rate of urban Mule Deer it can be a promising conservation strategy for young deer not yet entirely desensitized to human presence</big><ref name=":1" /><big>.</big>

Members of the St'át'imc territory in British Columbia have also discussed implementing a regulation to protect Mule Deer fawning zones which works to support the species while also engaging with Indigenous communities in conservation practices</big> <ref name=":2" /><big>.</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water</big><ref name=":1" /><big>.

== Introduction ==
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research (8). Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America (9). Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia (9). Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres (1). Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from the increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by land use change.</big>

Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred (8).</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations (4). It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations (8).</big>

=== <big>Water Availability</big> ===
<big>Human infrastructure development often entails the rerouting or depletion of natural water sources in mule deer habitats. Human made sources of water for mule deer are also not always available for mule deer since they can change quite unpredictably. Climate change impacts precipitation and drier summers impact water availability seasonally for mule deer. Overall, water availability is an important feature of mule deer habitats and human development often threatens this vital need (8).</big>

=== <big>Invasive Species</big> ===
<big>Mule deer habitat function is primarily impacted by the prevalence of non-native invasive grasses. These grasses can worsen wildfire spread and reduce habitat recovery after wildfires have spread. Wildfires destroy large areas of suitable habitat for mule deer, invasive species worsen the impacts of these events and amplify the impact of habitat loss on mule deer (8).</big>

<big>'''Figure 1''' ''Note.'' Different stand needs of mule deer in winter forage areas in the Caribou Forest Region of British Columbia (1).</big>

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas (2). The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce (1). Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas.

== Current Conservation Efforts ==

== Looking Forward ==

=== <big>Indigenous Land Management Practices</big> ===
<big>Indigenous communities need to be included beyond field-level management in order to provide ecological knowledge that is rooted in centuries of intergenerational wisdom if we want to work towards improving the climate resiliency and long-term preservation of native species and land (9). Looking towards the future, efforts must be put towards Indigenous sovereignty through the use of collaborative governance in order to honour both Indigenous ideas and ecological practices as well as to work towards decreasing the negative environmental impacts on the Mule Deer population in British Columbia that arise from the growth of urban centres (9).</big>

Future efforts must aim to reconcile the objectives of wildlife conservation, ecological health, and Indigenous sovereignty through collaborative governance. By fostering genuine partnerships and embedding Indigenous values into legislative frameworks, British Columbia can improve ecological resilience and social equity – creating benefits that extend beyond Indigenous communities, while honouring our interdependence and ensuring collective continuity in the face of a changing climate (Whyte, 2017).

=== <big>Habitat Fragmentation</big> ===
<big>Avoid and minimize disrupting corridors and disturbing terrain used by mule deer to access forage areas when developing infrastructure also manage and offset impacts by establishing new ideal corridors when they are lost (8).</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water (8).</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer (8).</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss, fragmentation and lack of water availability. This habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Human created light and water pollution are also issues the Mule Deer are currently facing. There are many mitigation efforts that humans can implement to lessen their impact on the Mule Deer. This includes addition of shubbery and water to the landscape, in combination with minimizing the disruption of habitats. Overall, continued monitoring of the Mule Deer's is necessary to understand and mitigate the ways in which they are being impacts. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-10T16:14:53Z

KatelynPutz:

== Introduction ==
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research (8). Mule Deer are an Indigenous species to the territory covering the West Coast down to the Great Plains of North America (9). Mule Deer are known to inhabit regions in British Columbia with rugged topography containing areas of vegetation and are noted as a vital food source and economic asset to Indigenous people in British Columbia (9). Mule Deer require shelter and food, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres (1). Expanding urban development is negatively impacting non-urban deer populations by causing habitat fragmentation leading to the reduction of available vegetation and forest canopy cover, which is especially important for populations residing in regions with high snowfall. Light pollution that is produced from the increasingly prevalent urban centres is also acknowledged as impacting Mule Deer's foraging patterns despite plentiful vegetation being available. Therefore, as urbanization grows across British Columbia, Mule Deer are being negatively impacted by extreme habitat fragmentation, light and natural resource pollution, and food scarcity driven by land use change.</big>

== Habitat of the Mule Deer ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred (8).</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations (4). It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations (8).</big>

=== <big>Water Availability</big> ===
<big>Human infrastructure development often entails the rerouting or depletion of natural water sources in mule deer habitats. Human made sources of water for mule deer are also not always available for mule deer since they can change quite unpredictably. Climate change impacts precipitation and drier summers impact water availability seasonally for mule deer. Overall, water availability is an important feature of mule deer habitats and human development often threatens this vital need (8).</big>

=== <big>Invasive Species</big> ===
<big>Mule deer habitat function is primarily impacted by the prevalence of non-native invasive grasses. These grasses can worsen wildfire spread and reduce habitat recovery after wildfires have spread. Wildfires destroy large areas of suitable habitat for mule deer, invasive species worsen the impacts of these events and amplify the impact of habitat loss on mule deer (8).</big>

<big>'''Figure 1''' ''Note.'' Different stand needs of mule deer in winter forage areas in the Caribou Forest Region of British Columbia (1).</big>

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas (2). The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce (1). Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover (7). Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density (3). Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors (3). Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations (3).</big>

== Current Conservation Efforts ==

== Looking Forward ==

=== <big>Vegetation</big> ===
<big>Planting temporary winter forage, seeding desirable grasses after wildfires, bacterial soil amendments to minimize invasive species of grasses, planting native shrub seedlings (8).</big>

=== <big>Habitat Fragmentation</big> ===
<big>Avoid and minimize disrupting corridors and disturbing terrain used by mule deer to access forage areas when developing infrastructure also manage and offset impacts by establishing new ideal corridors when they are lost (8).</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water (8).</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer (8).</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss, fragmentation and lack of water availability. This habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Human created light and water pollution are also issues the Mule Deer are currently facing. There are many mitigation efforts that humans can implement to lessen their impact on the Mule Deer. This includes addition of shubbery and water to the landscape, in combination with minimizing the disruption of habitats. Overall, continued monitoring of the Mule Deer's is necessary to understand and mitigate the ways in which they are being impacts. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

2026-04-10T15:36:03Z

KatelynPutz:

== Introduction ==
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research (8). There has been a dramatic increase in the number of Mule Deer observed in urban areas, while Mule Deer populations residing in non-urban regions have been reported as declining (6). Mule Deer require shelter and food sources, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres (1). The ideal natural habitat for Mule Deer in British Columbia consists of mountainous, forested areas, which contain rich understories where they can forage for shrubs. Dependent on snowfall amounts and fire exposure across British Columbia, abundant Mule Deer populations are often found under deciduous canopies due to the increased foraging opportunities compared to closed coniferous canopies(6). Increasing urbanization is impacting non-urban deer populations negatively by encroaching on these natural habitats which is resulting in a reduction in forest canopy cover, which specifically affects Mule Deer residing in areas with heavy snow fall, and foraging opportunities across the province. Therefore, Mule Deer are impacted by increased rates of habitat fragmentation, pollution, and food scarcity driven by the increase of urbanization across British Columbia.</big>

== Habitat Requirements ==
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred (8).</big>

== Impacts of Urbanization on Mule Deer Habitat ==

=== <big>Habitat Fragmentation</big> ===
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations (4). It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations (8).</big>

=== <big>Water Availability</big> ===
<big>Human infrastructure development often entails the rerouting or depletion of natural water sources in mule deer habitats. Human made sources of water for mule deer are also not always available for mule deer since they can change quite unpredictably. Climate change impacts precipitation and drier summers impact water availability seasonally for mule deer. Overall, water availability is an important feature of mule deer habitats and human development often threatens this vital need (8).</big>

=== <big>Invasive Species</big> ===
<big>Mule deer habitat function is primarily impacted by the prevalence of non-native invasive grasses. These grasses can worsen wildfire spread and reduce habitat recovery after wildfires have spread. Wildfires destroy large areas of suitable habitat for mule deer, invasive species worsen the impacts of these events and amplify the impact of habitat loss on mule deer (8).</big>

<big>'''Figure 1''' ''Note.'' Different stand needs of mule deer in winter forage areas in the Caribou Forest Region of British Columbia (1).</big>

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas (2). The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce (1). Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover (7). Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density (3). Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors (3). Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations (3).</big>

== Current Conservation Efforts ==

== Looking Forward ==

=== <big>Vegetation</big> ===
<big>Planting temporary winter forage, seeding desirable grasses after wildfires, bacterial soil amendments to minimize invasive species of grasses, planting native shrub seedlings (8).</big>

=== <big>Habitat Fragmentation</big> ===
<big>Avoid and minimize disrupting corridors and disturbing terrain used by mule deer to access forage areas when developing infrastructure also manage and offset impacts by establishing new ideal corridors when they are lost (8).</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water (8).</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer (8).</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss, fragmentation and lack of water availability. This habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Human created light and water pollution are also issues the Mule Deer are currently facing. There are many mitigation efforts that humans can implement to lessen their impact on the Mule Deer. This includes addition of shubbery and water to the landscape, in combination with minimizing the disruption of habitats. Overall, continued monitoring of the Mule Deer's is necessary to understand and mitigate the ways in which they are being impacts. </big>

The Impacts of Urbanization on Mule Deer in British Columbia

== Introduction ==
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research (8). There has been a dramatic increase in the number of mule deer observed in urban areas, while mule deer populations residing in non-urban regions have been reported as declining (6). Mule Deer require shelter and food sources, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres (1). Therefore, Mule Deer are impacted by increased rates of habitat fragmentation, pollution, and food scarcity driven by the increase of urbanization across British Columbia.</big>

== Background ==

=== <big>Habitat Needs</big> ===
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred (8).</big>

=== <big>Habitat Fragmentation</big> ===
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations (4). It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations (8).</big>

=== <big>Water Availability</big> ===
<big>Human infrastructure development often entails the rerouting or depletion of natural water sources in mule deer habitats. Human made sources of water for mule deer are also not always available for mule deer since they can change quite unpredictably. Climate change impacts precipitation and drier summers impact water availability seasonally for mule deer. Overall, water availability is an important feature of mule deer habitats and human development often threatens this vital need (8).</big>

=== <big>Invasive Species</big> ===
<big>Mule deer habitat function is primarily impacted by the prevalence of non-native invasive grasses. These grasses can worsen wildfire spread and reduce habitat recovery after wildfires have spread. Wildfires destroy large areas of suitable habitat for mule deer, invasive species worsen the impacts of these events and amplify the impact of habitat loss on mule deer (8).</big>

<big>-UPLOAD IMAGE FROM WORD DOC-</big>

<big>'''Figure 1''' ''Note.'' Different stand needs of mule deer in winter forage areas in the Caribou Forest Region of British Columbia (1).</big>

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas (2). The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce (1). Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover (7). Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density (3). Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors (3). Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations (3).</big>

== Current Remedial Actions ==

== Path Forward ==

=== <big>Vegetation</big> ===
<big>Planting temporary winter forage, seeding desirable grasses after wildfires, bacterial soil amendments to minimize invasive species of grasses, planting native shrub seedlings (8).</big>

=== <big>Habitat Fragmentation</big> ===
<big>Avoid and minimize disrupting corridors and disturbing terrain used by mule deer to access forage areas when developing infrastructure also manage and offset impacts by establishing new ideal corridors when they are lost (8).</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water (8).</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer (8).</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss, fragmentation and lack of water availability. This habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Human created light and water pollution are also issues the Mule Deer are currently facing. There are many mitigation efforts that humans can implement to lessen their impact on the Mule Deer. This includes addition of shubbery and water to the landscape, in combination with minimizing the disruption of habitats. Overall, continued monitoring of the Mule Deer's is necessary to understand and mitigate the ways in which they are being impacts. </big>

== Introduction ==
<big>Mule Deer (Odocoileus hemionus), a native species to North America, have experienced high population growth rates across British Columbia. Due to this growth, the impacts of urbanization on Mule Deer have become increasingly important areas of research (8). There has been a dramatic increase in the number of mule deer observed in urban areas, while mule deer populations residing in non-urban regions have been reported as declining (6). Mule Deer require shelter and food sources, primarily consisting of foraged shrubs and plant debris, which is seen to be negatively impacted from causes such as deforestation and the growing development of urban centres (1). Therefore, Mule Deer are impacted by increased rates of habitat fragmentation, pollution, and food scarcity driven by the increase of urbanization across British Columbia.</big>

== Background ==

=== <big>Habitat Needs</big> ===
<big>Historical vegetation conditions have degraded over time, with human impact influencing vegetation distribution, quality, vertical and horizontal density, and proximity to water and security cover, all of which are required for the maintenance of mule deer populations in an area. Mule deer also have seasonal habitat needs, if an area meets all annual needs the population will remain however, most often mule deer will migrate between habitat areas to meet seasonal needs, especially seeking thermal cover in the winter. Security cover is also an important feature of mule deer habitats, vegetation or landscape features which allow mule deer to hide from predators for survival are preferred (8).</big>

=== <big>Habitat Fragmentation</big> ===
<big>The habitat fragmentation caused by urbanization has profound impacts; researchers have found that there are genetic impacts on mule deer subpopulations corresponding to urban infrastructure that reduces habitat connectivity separating sub-populations from one another decreasing genetic variability within sub-populations (4). It is evident that increased connectivity of habitats either through highway corridors and safe crossings or decreased road density results in an increased habitat range reflected by sub-populations passing genes between sub-populations. Ungulates, like mule deer, require a large area to roam to prevent food scarcity and habitat fragmentation has shown to be a threat to this need. Habitat fragmentation, can also result in increased energetic costs for mule deer, if mule deer have to travel farther distances to meet seasonal needs or especially if adequate thermal cover is not available in the winter the energetics costs increase significantly which can lead to the dwindling populations (8).</big>

=== <big>Water Availability</big> ===
<big>Human infrastructure development often entails the rerouting or depletion of natural water sources in mule deer habitats. Human made sources of water for mule deer are also not always available for mule deer since they can change quite unpredictably. Climate change impacts precipitation and drier summers impact water availability seasonally for mule deer. Overall, water availability is an important feature of mule deer habitats and human development often threatens this vital need (8).</big>

=== <big>Invasive Species</big> ===
<big>Mule deer habitat function is primarily impacted by the prevalence of non-native invasive grasses. These grasses can worsen wildfire spread and reduce habitat recovery after wildfires have spread. Wildfires destroy large areas of suitable habitat for mule deer, invasive species worsen the impacts of these events and amplify the impact of habitat loss on mule deer (8).</big>

<big>'''Figure 1''' ''Note.'' Different stand needs of mule deer in winter forage areas in the Caribou Forest Region of British Columbia (1).</big>

=== '''<big>Food Scarcity</big>''' ===
<big>Mule Deer utilize location for forage more intensely when water and security cover are present, urbanization poses a threat to these ideal forage areas, since human impacts often result in ecosystems that are unable to support the vegetation needed for security cover, thus increasing food scarcity by decreasing the number of ideal forage areas (2). The ideal forage for mule deer are shrubs, however, with increasing logging and subsequent habitat fragmentation, areas with sufficient shrubbery are increasingly scarce especially in the winter. Mule deer have a multitude of stand needs in forage areas to ensure energetic costs do not become too high, and adequate security is present; figure 1 illustrates these needs. Without forage areas with these qualities the energetic cost of travel and maintaining body temperature during the winter become very high and food to meet this increased energetic demand is scarce (1). Despite an increased prevalence of shrubbery in clearcut areas, mule deer heavily avoid these areas since they on average have much deeper snow than coniferous and deciduous forest areas. Mule deer have been observed to select deciduous forest areas for forage likely due to increased shrubbery, even though there is reduced snow inception and thermal cover in comparison to coniferous forest areas which are often associated with less shrubbery but higher snow inception and thermal cover (7). Generally, research has observed that open deciduous forest areas are also important to winter forage like coniferous forest areas, likely due to snow depth being one of the most important factors to consider in the management of food scarcity for mule deer.</big>

=== '''<big>Pollution</big>''' ===
<big>Urbanization commonly results in artificial light pollution; researchers have found that mule deer are much less likely to utilize locations for forage when high levels of artificial light are present, even if these locations have a high vegetation density (3). Artificial light is also observed to shorten the time mule deer spend at forage areas, showing that generally mule deer prefer to graze in areas with natural light sources likely due to their need for security cover from predators. Mule deer are also more likely to cross roads and pass through corridors when there are less sources of artificial light. Generally, it is important to consider the impacts of artificial light pollution on the probability of use of forage areas and the probability of crossing roads versus safe corridors (3). Pollution of water sources is also a threat to mule deer, this species aims to balance energetic costs with meeting needs like drinking water, if the nearest water source is polluted or if the most suitable habitat has a polluted water source it is still the most likely to be used and travelling long or steep distances to reach clean water sources increases energetic costs which evidently threaten the health of mule deer populations (3).</big>

== Current Remedial Actions ==

== Path Forward ==

=== <big>Vegetation</big> ===
<big>Planting temporary winter forage, seeding desirable grasses after wildfires, bacterial soil amendments to minimize invasive species of grasses, planting native shrub seedlings (8).</big>

=== <big>Habitat Fragmentation</big> ===
<big>Avoid and minimize disrupting corridors and disturbing terrain used by mule deer to access forage areas when developing infrastructure also manage and offset impacts by establishing new ideal corridors when they are lost (8).</big>

=== <big>Water availability</big> ===
<big>Water development entails human creation of additional water sources for mule deer populations in areas where water scarcity is an issue or during summer months when it becomes an issue, however this must be done carefully to avoid providing contaminated water (8).</big>

=== <big>Habitat Evaluation</big> ===
<big>Habitat evaluation and monitoring overall is one of the best investments in determining and responding to the impacts of urbanization on mule deer populations, when the issues are identified the path forward is much clearer (8).</big>

== Conclusion ==

<big>As urbanization is increasing in BC, the impacts we are seeing on Mule Deer are also increasing. Human impact on vegetation is leading to habitat loss, fragmentation and lack of water availability. This habitat fragmentation in combination with logging has created greater food scarcity for the Mule Deer population, who primarily rely on shrubs. Human created light and water pollution are also issues the Mule Deer are currently facing. There are many mitigation efforts that humans can implement to lessen their impact on the Mule Deer. This includes addition of shubbery and water to the landscape, in combination with minimizing the disruption of habitats. Overall, continued monitoring of the Mule Deer's is necessary to understand and mitigate the ways in which they are being impacts. </big>

== Introduction ==

== The impacts of urbanization on mule deer has become an increasing area of research interest due to the drastically growing mule deer populations across British Columbia (Wright et al., 2020). Regionally, there has been a dramatic increase in the number of mule deer observed in urban areas while mule deer populations residing in non-urban regions have declined (Mathieu et al, 2018). This shift in where deer are residing is likely impacted by increased rates of habitat fragmentation which is caused by logging, specifically Douglas-fir growths (Armleder & Dawson, 1992).
