Our research on Sierra Nevada lake ecosystems focuses on amphibian conservation and lake ecology. To turn our research results into management actions, we work in close partnership with an array of land and wildlife management agencies to design and implement science-based solutions to lake-related management challenges. These include recovery of the endangered mountain yellow-legged frog and impacts of non-native trout. The National Park Service, U.S. Fish and Wildlife Service, U.S. Forest Service, and California Department of Fish and Wildlife all play important roles in this process.
