Range DescriptionThis species can be found in south-western British Columbia, Canada, south through the Puget/Willamette Valley trough and the Columbia River gorge in south-central Washington to the Cascades range at least to the Klamath Valley in Oregon, USA. It has been extirpated from much of western Oregon and Washington. Some records are based on misidentified Rana aurora (Green et al. 1997). Historically, it has occurred in north-eastern California (Jennings and Hayes 1994, Hayes 1994). It occurs at an elevation of 20-1,570m asl.
