Over  the last 22 years, 2,634 mule deer, 748 elk, and 353 moose have been killed by vehicles in Teton County, Wyoming. In Wyoming, more than 5,000 wildlife-vehicle collisions (WVCs) have been documented every year, on average, over the last three years. These collisions pose a serious threat to highway safety – accounting for 15-18% of all reported collisions. They also have significant negative impacts on wildlife populations – reducing their numbers and impeding their movements through their seasonal ranges and along their migratory corridors. Further, these collisions are costly. All together, deer-vehicle collisions in Wyoming (which make up >85% of all WVCs in the state) total approximately $24-29 million per year in injury and damage costs and an additional $20-23 million per year in lost wildlife value (Riginos and Graham 2015).

Having this information is crucial because it not only shows the frequency of such interactions, but also indicates the extent of opportunity to intervene and potentially rehabilitate these animals.
