Protecting an Endangered Frog
The Sierra Nevada yellow-legged frog (Rana sierrae) was once the most abundant vertebrate in the mountains of California. Steep population declines during the past century have pushed this species to the brink of extinction. Through this project the park tagged and radio-tracked frogs to identify critical habitats and movement corridors. Theefforts have helped improve the effectiveness of conservation actions undertaken to recover the species.
