Puget Oregonian snail (Cryptomastix devia Gould, 1846) is a large (adult shell, 18-25 mm diameter) land snail endemic to western North America ranging from southwestern British Columbia (B.C.) through Washington to northern Oregon. In B.C., the species is known from three historical (1850-1905) records on Vancouver Island and the Lower Fraser Valley. Surveys between 1984 and 2006 within the historic range have not located any new populations or old shells. In 2002, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designated Puget Oregonian snail as Extirpated from Canada. Potential threats to Puget Oregonian snail include habitat loss and degradation, competition from and presence of exotic plants and animals, and pesticide use. The recovery goal is to confirm the presence/absence of Puget Oregonian snail within the species' historic range and protect any extant population(s) if found. A single-species approach is taken in this recovery strategy because of the extirpated status of the species, which requires special considerations. Inventory, habitat assessment, and public education should be completed within a multi-species program.
