Determining Effectiveness of Wildlife-Vehicle Collision Mitigation Projects

The objective of this research is to estimate passage rates or relative use of crossing structures for large mammals and identify other wildlife species using crossings at constructed and planned wildlife-vehicle collision mitigation projects for a 2 – 3 year period. In instances where fencing will be constructed during the study we will compare use of crossing structures over time to evaluate the effectiveness of the fencing. Specific research objectives are: • Compare wildlife passage rates or relative use of crossings with studies done in other western states. • Identify infrastructure shortcomings or other factors that contribute to low passage rates or low relative use rates. • Collate and review wildlife-vehicle collision and carcass collection data to determine the effectiveness of constructed projects in reducing wildlife-vehicle collisions, or at least document baseline wildlife-vehicle collision rates for planned projects. • Create a guide for designing effective wildlife crossings and for improving existing drainage structures for mule deer (Odocoileus hemionus), elk (Cervus elaphus), black bear (Ursus americanus) and Mountain lion (Puma concolor). Cameras were mounted at multiple crossing locations at highway sites across New Mexico to identify passage rates by animal species. Additionally, carcass and crash data are being collected and analyzed to estimate impact of mitigation interventions on traffic crashes. Finally, at one location, driver responses to radar triggered signs is being monitored and evaluated.
