COSEWIC assessment and update status report on the Chiselmouth in Canada

Existing Protection or Other Status

The 1997 COSEWIC status of chiselmouth in Canada is Data Deficient (Coffie 1998). Chiselmouth is blue-listed by the CDC in British Columbia. CDC global rank is G5 (globally secure – common to very common, not susceptible to extirpation or extinction), provincial rank is S3 (provincially vulnerable – provincially rare and local, making it susceptible to extirpation or extinction). It has no protection in Canada, and has no protection in the United States unless it becomes listed under U.S. endangered species legislation, which is extremely unlikely given the robust populations in the Pacific Northwest. Very little of the range of chiselmouth falls within any protected area.
