Description

Westslope cutthroat trout, the only subspecies of cutthroat trout native to Alberta, historically inhabited most streams in south-western Alberta from the alpine to the prairies. Today they occupy only a small fraction of their historic range and are largely restricted to the Rocky Mountains and foothills. The species is listed as Threatened in Alberta. The goal of this recovery plan is to protect and maintain the existing pure Westslope cutthroat trout population at self-sustaining levels, and re-establish additional pure populations to self-sustaining levels within the species' historical range in Alberta. The plan provides background information on the Westslope cutthroat trout, describes the threats facing the species, outlines proposed strategies to address these threats, and presents an action plan that lists priority actions required to maintain and restore the species.

Description

This wildlife status report looks at the westslope cutthroat trout, a polytypic species of trout endemic to western North America. Populations in Alberta and British Columbia exist on the northern periphery of the species' range. Although historically a widespread species, westslope cutthroat trout has shown dramatic global declines in the number and distribution of populations due to habitat degradation, overharvesting and the introduction of nonnative species. The Alberta population of westslope cutthroat trout has a national designation of Threatened. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.
