Assessment rationale/justification
This rabbit was first recorded in Canada about 70 years ago and has since increased its range in the Okanagan, where it may have reached the maximum possible extent of its distribution. Remaining rabbit habitat in the Okanagan is less than 8000 hectares, increasingly fragmented, and continues to be lost to urbanization and agriculture. The total population size, based on available habitat, is probably less than 3500 individuals. Rescue potential from Washington is minimal because of the declining availability of habitat. There are substantial uncertainties about the current area of occupancy, which may have declined over the last few decades as habitat has been lost.; L'espèce a été observée pour la première fois au Canada il y a environ 70 ans et a depuis étendu son aire de répartition dans la région de l'Okanagan, o๠elle a peut-être atteint sa distribution maximale. L'habitat restant de l'espèce dans la région de l'Okanagan couvre moins de 8 000 hectares, est de plus en plus fragmenté et diminue toujours en raison de l'urbanisation et de l'agriculture. La taille totale de la population selon l'habitat disponible, se compose probablement de moins de 3 500 individus. La possibilité d'une immigration de l'État de Washington est minimale en raison de la disponibilité décroissante de l'habitat. Il existe des incertitudes importantes quant à la zone d'occupation actuelle, laquelle aurait pu connaà®tre un déclin au cours des quelques dernières décennies alors qu'il y a eu perte d'habitat.
