Glacier and Mount Revelstoke National Parks are bisected by a major national commercial highway (Hwy #1). Vehicle collisions with wildlife are a major stressor and have serious social, economic, and ecological impacts. Animals crossing highways are at risk of mortality and people traveling in vehicles risk personal injury. Mount Revelstoke and Glacier national parks record the location, species and number of mortalities that occur on driveable roads to analyze highway related mortality and identify key areas for mitigation measures.
