Assessment rationale/justification
There are only about 450 mature individuals in a single Canadian population with a range of 13 km², adjacent to a small area of occupied habitat in the USA. Threats to the population include trapping by pest removal companies and property owners. The habitat has been degraded through fragmentation and urbanization. There is no evidence of decline over the last 10 years. It is uncertain whether immigration across the international border may rescue the Canadian population.; Il existe seulement environ 450 individus matures dans une seule population canadienne ayant une aire de répartition de 13km², adjacente à une petite zone d'habitat occupée aux États-Unis. La population est menacée par le piégeage effectué par les entreprises d'extermination des espèces nuisibles et les propriétaires fonciers. L'habitat s'est dégradé par suite de sa fragmentation et de l'urbanisation. Il n'y a aucune preuve de déclin depuis les dix dernières années. On ne sait pas si l'immigration d'individus provenant des États-Unis peut aider à rétablir la population canadienne.
