The Oregon Spotted Frog (Rana pretiosa) is a Pacific Northwest endemic whose global historical distribution ranged from the southwestern corner of British Columbia south to the northeastern corner of California. It is Canadas most endangered amphibian, with an estimated population of only 316 adults at 4 occupied locations (one of which may be near extirpation) in 2010.
The Oregon Spotted Frog is endangered throughout its North American range. It is extirpated from at least 70% of its known historical locations and as much as 90% of its extrapolated historical range. There is an immediate need to facilitate its recovery to a level at which extinction is no longer an immediate threat.
Based on the Oregon Spotted FrogâÂÂs limited distribution, small population sizes, and small habitat areas, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) first designated the Oregon Spotted Frog as âÂÂEndangeredâ in November 1999. The Oregon Spotted Frog is listed as Endangered in Canada on Schedule 1 of the Species at Risk Act (SARA). In British Columbia, the Oregon Spotted Frog is ranked S1 (critically imperiled) by the Conservation Data Centre and is on the provincial Red list. The B.C. Conservation Framework ranks the Oregon Spotted Frog as a priority 1 under Goal 1 (contribute to global efforts for species and ecosystem conservation) and Goal 3 (maintain the diversity of native species and ecosystems)....
