Assessment rationale/justification
Estimated total population size exceeds 13,000 mature individuals. Declines have been reported in Alberta and parts of British Columbia and Ontario. A distinct subspecies may be extirpated from Vancouver Island. Many pelts used locally are not included in official statistics, and harvest levels may be underreported. There is no evidence, however, of a decline in harvest. There are no data on overall population trends other than those provided by local knowledge and harvest monitoring programs. This species' habitat is increasingly fragmented by industrial activity, especially in the southern part of its range, and increased motorized access will increase harvest pressure and other disturbances. The species has a low reproductive rate and requires vast secure areas to maintain viable populations.; La population totale estimée dépasse les 13 000 individus matures. Des déclins ont été signalés en Alberta et dans certaines régions de la Colombie-Britannique et de l'Ontario. Une sous-espèce distincte pourrait avoir disparu de l'à®le de Vancouver. De nombreuses pelleteries utilisées à l'échelle locale ne sont pas incluses dans les statistiques officielles, et les taux de prises pourraient avoir été sous-déclarés. Cependant, il n'y a aucune preuve d'un déclin des prises. Il n'existe aucune donnée sur les tendances démographiques générales autre que celles fournies par les connaissances locales et les programmes de surveillance des prises. L'habitat de cette espèce est de plus en plus fragmenté par l'activité industrielle, surtout dans la partie sud de son aire de répartition; de plus, l'accès accru par véhicule motorisé augmentera la pression relative aux prises et d'autres perturbations. L'espèce a un taux de reproduction faible et nécessite de vastes aires protégées pour maintenir des populations viables.

History
The species was considered a single unit and designated Special Concern in April 1982. Split into two populations in April 1989 (Western and Eastern populations). The Western population was designated Special Concern in April 1989. Status re-examined and.; L'espèce a été désignée comme une unité et a été désignée ' préoccupante ' en avril 1982. Division en deux populations en avril 1989 (population de l'Ouest et population de l'Est). La population de l'Ouest a été désignée ' préoccupante ' en avril 1989. Réexamen et confirmation du statut en mai 2003.
