Planning-Support for Mitigation of Wildlife-Vehicle Collisions and Highway Impacts on Migration Routes in Wyoming

Wyoming is home to abundant big game, including long-distance migratory species such as mule deer, elk, and pronghorn. Where these animals’ movement patterns intersect with roads, vehicles often hit animals. This poses a threat both to highway safety and to wildlife populations. Here, the authors identified 27 deer-vehicle collision “hotspots” in the state. The authors then analyzed the ecological and road characteristics that are associated with these areas. High rates of deer-vehicle collision are most strongly associated with high traffic volumes, high speed limits, deer migration habitat, deer winter-use areas, irrigated agriculture, and wetlands. The authors then examined the spatial and temporal patterns of collisions for each hotspot in relation to known deer migration routes and winter-use areas. Using these results, the authors suggest mitigation measures that are most suitable for each of the 27 collision hotspots.
