The Carson River Deer Herd is an interstate deer herd, which inhabits portions of El Dorado, Alpine, and Mono counties, plus Douglas County in Nevada. The herd has shown a steady population decline. The reasons for this decline are changes in habitat, predation, road kill and other factors. This project will capture female Mule deer on their summer range and fit them with satellite collars. The information gathered by the California Department of Fish and Wildlife will provide habitat use, migration corridors, important critical habitats (fawning, holding areas, etc.) and survival rates. This will aid in developing management strategies and improved decision-making processes for the future of this deer herd. This is the second year of this study in zone X8.
