The final report contains a stepwise approach for the identification and prioritization of large mammal crash hotspots and large mammal carcass hotspots. Mule deer crash and mule deer carcass data from Caltrans District 10 were used as an example. The mule deer crash and mule deer carcass hotspots were ranked based on human safety, nature conservation, and economic parameters. Finally, mitigation measures were suggested for the deer crash and deer carcass hotspots. The mitigation measures were aimed at reducing the number of large mammal-vehicle collisions while still allowing wildlife to cross the road.
This project focused on providing a strategy for the potential future implementation of mitigation measures for wildlife along highways. The general goals of the measures were to: 1.) reduce direct wildlife mortality of large mammal species along highways in Caltrans District 10 and elsewhere in California, and 2.) maintain or improve habitat connectivity for a wide variety of wildlife species, specifically amphibian, reptile, and mammal species, across highways in Caltrans District 10 and elsewhere in California. The project includes data from approximately 1,836 miles of highway in Caltrans District 10.
This purpose of this project was to provide a strategy for the potential future implementation of mitigation measures for wildlife along highways.
