Canadian Species at Risk - May 2001

About COSEWIC

COSEWIC Mandate


The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) determines the national status of wild species, subspecies, varieties, and nationally significant populations that are considered to be at risk in Canada. Designations are made on all native species for the following taxonomic groups: mammals, birds, reptiles, amphibians, fish, lepidopterans, molluscs,
vascular plants, mosses, and lichens.

COSEWIC Membership


COSEWIC comprises representatives from each provincial and territorial government wildlife agency, four federal agencies (Canadian Wildlife Service, Parks Canada Agency, Department of Fisheries and Oceans, Canadian Museum of Nature), three nonjurisdictional members, and cochairs of species specialist groups. The committee meets at least once per year to consider status reports on candidate species.
