The Nutria is an introduced species from South America brought here for fur-farming. It first escaped captivity into the Green River in 1935 and has escaped or been released and spread in the lower elevation areas from Skagit County to the Vancouver, Washington area. It is thought that their sensitivity to cold has limited their spread although some are found in Yakima County.

Low elevation zones within their range, such as Sitka Spruce, Puget Sound Douglas-fir, Willamette Valley, the Cowlitz River, Woodland/Prairies Mosaic, and the steppe zones were core. Good habitat in these zones were irrigated farmlands, and fresh/water wetlands.
