Foothill Yellow-Legged Frog


The foothill yellow-legged frog (Rana boylii) is a small frog found in the Coast Ranges from Oregon through California as well as in the foothills of the Sierra Nevada and southern Cascade Range in California. It is a Federal Species of Concern and California Species of Special Concern.

Once thriving across their range, now foothill yellow-legged frogs have disappeared from more than half their historical localities due to a very long list of threats: dams, water development and diversions, timber harvest, mining, livestock grazing, roads and urbanization, marijuana cultivation, off-road vehicles, climate change, pollution, invasive species and disease.
