Montana DOT Report Evaluates Wildlife Mitigation Measures

The Montana Department of Transportation has released a report evaluating the wildlife crossings installed along U.S. 93 North on the Flathead Indian Reservation. The highway reconstruction project included installation of wildlife overpasses or culverts at 39 locations and wildlife exclusion fences on 8.71 miles of road. Using research conducted from 2002-2015 to address the effectiveness of the mitigation measures, the report finds that collisions with large mammals has been reduced by more than 50 percent. The report indicates that wildlife fences were most effective in reducing collisions with large mammals if the fences were installed over road lengths of at least 3.1 miles. For more information, link to the report. (1-7-17)
