In the Tahoe National Forest, California Department of Fish and Wildlife scientists are working to balance native species restoration with recreational fishing. This summer, for the first time in the Tahoe National Forest, CDFW will begin work to restore Sierra Nevada yellow-legged frog (Rana sierrae) habitat by removing introduced trout from four alpine lakes and four small ponds within the Five Lakes Basin area. The Sierra Nevada yellow-legged frog is listed as threatened under California’s Endangered Species Act and endangered under the federal Endangered Species Act.
