Action Plan for the Milk and St. Mary Rivers drainage basins in Canada
This action plan addresses two species found in the Milk River and St. Mary River drainage basins, Alberta, and follows a multi-species approach to protect and maintain self-sustaining populations of both species. Both the St. Mary and Milk River drainage basins originate in Montana along the eastern slopes of the Rocky Mountains and flow north and north east, respectively, into Alberta. This action plan builds on the recovery strategies of the Rocky Mountain Sculpin (Eastslope populations) and the Western Silvery Minnow. In Alberta, the Rocky Mountain Sculpin (Cottus sp.) is found in the St. Mary River drainage and the Milk River drainage and the Western Silvery Minnow (Hybognathus argyritis) is found in the Milk River drainage. Both species are listed as Threatened under the federal Species at Risk Act.
