Range DescriptionHistorical range extended from the Diamond Mountains northeast of the Sierra Nevada in Plumas County, and from just north of the Feather River in the extreme northwest region of the Sierra Nevada, California, south through the Sierra Nevada to Inyo County, California, and east to Mt. Rose, northeast of Lake Tahoe, in Washoe County, Nevada (Vredenburg et al. 2007). West of the Sierra Nevada crest, the southern part of the range is bordered by ridges that divide the Middle and South Fork of the Kings River, ranging from Mather Pass to the Monarch Divide; east of the Sierra Nevada crest, R. sierrae occurs in the Glass Mountains just south of Mono Lake (Mono County) and along the east slope of the Sierra Nevada south to the type locality at Matlock Lake (Inyo County) (Vredenburg et al. 2007). Rana sierrae is now extirpated from Nevada and from large portions of the historical range in the Sierra Nevada of California.
