Rana sierrae

Endangered

Shallow lakes that dry in summer endanger this high-elevation frog.

Predation by non-native trout also plays a large role in limiting breeding and tadpole development.

The Sierra Nevada yellow-legged frog or Sierra Nevada Mountain yellow-legged frog (Rana sierrae) is a true frog endemic to the Sierra Nevada of California and Nevada in the United States. It was formerly considered Rana muscosa until a 2007 study elevated the more central and northern populations to full species status, restricting R. muscosa to the southern Sierra Nevada and southern California.

Shallow lakes that dry in summer endanger this high-elevation frog. Predation by non-native trout also plays a large role in limiting breeding and tadpole development. Many factors endangering the southern mountain yellow-legged frog also affect this species.
