Abstract
Animal–vehicle collisions (AVCs) are a serious problem that can result in property damage and human and animal injury and death. This study investigated the role that elevation, slope, and vegetation may have in AVC locations (mule deer Odocoileus hemionus and elk Cervus canadensis) in several canyon corridors in north central Utah. This was done by comparing these characteristics around known AVCs with those around control points where AVCs did not occur. The study found that elevation was significantly lower around AVC points, slope was significantly greater, and there was no difference in overall vegetation when measured with NDVI, but there was a difference in percentage of Sage brush (Artemisia tridentata Nutt) steppe around the points. AVCs may occur in these areas because mule deer tend to be more active in the lower elevations and use steeper slope for cover. Also, in areas with greater slope, the road will probably be curvier and provide less driver visibility than in areas with less steep slope. These results may help guide where to place deer warning signs and other AVC mitigation strategies.
