Critical Habitat Orders

Critical Habitat of the Western Silvery Minnow (Hybognathus argyritis) Order

The Western Silvery Minnow (Hybognathus argyritis) is a small cyprinid species native to northwestern North America. In Canada, the Western Silvery Minnow has only been confirmed in the Milk River in southern Alberta. In November 2001, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the status of the Western Silvery Minnow and classified the species as a threatened species. In June 2003, the Western Silvery Minnow was listed as threatened in Part 3 of Schedule 1 to the Species at Risk Act (SARA). Following an updated status report and reassessment by COSEWIC in April 2008, the COSEWIC status of the Western Silvery Minnow changed from threatened to endangered. However, in November 2017, COSEWIC reassessed the Western Silvery Minnow and changed the status back to threatened based on new knowledge of its habitat requirements, trends, biology and threats. The species meets the criteria for endangered, but was assessed as threatened because there is no evidence of decline in abundance and there is uncertainty in the severity of threats
