The threatened Yaak and Selkirk grizzly bear populations in northern Montana, Idaho, and Washington are integrally linked to populations in Canada and their long-term recovery requires cooperation between the U.S. and Canada. It is recognized that the forces that brought these populations to their threatened status in the U.S. are also operating in Canada. It follows that the solutions will also lie in both countries. To this end, the USFWS entered into a working relationship with Canadian biologist Michael Proctor of Birchdale Ecological Services to enhance recovery efforts between the countries. Proctor works closely with the British Columbian Ministry of Environment to implement a comprehensive recovery program that includes active research, reducing human-caused mortalities, enhancing inter-population movements, increasing public awareness, and augmenting these populations within Canada. Ongoing research projects include a DNA survey and population estimate, identification of linkage zones across Canadian Highway 3 using movement data from grizzly bears wearing GPS radio collars, and a landscape assessment of genetic status. Information gathered by these efforts will be used to prioritize conservation actions and enhance movements of bears between these small threatened populations and larger healthier ones within Canada, a management action that is key to their long-term recovery.
