Sierra Nevada yellow-legged frog

The Sierra Nevada yellow-legged frog or Sierra Nevada Mountain yellow-legged frog (Rana sierrae) is a true frog endemic to the Sierra Nevada mountains (in California and Nevada). 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. This species is very similar in appearance to the southern mountain yellow-legged frog, with which it was formerly identified. 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.
