Special Concern; Préoccupante
Assessment rationale/justification
This subspecies has a limited range, and a small extent of occurrence and area of occupancy. However, the extent of occurrence and area of occupancy appear to be constant. Its principal native habitat in the Okanagan as well as old fields is declining. Furthermore, old apple orchards where the mouse has been caught are being converted to vineyards. Dispersal distance is limited and the likelihood of rescue effect is small. Extensive sampling has revealed the occurrence of the mouse at more localities. 63,000 hectares of suitable habitat is protected.; Cette sous-espèce a une aire de répartition limitée, une petite zone d'occurrence et une petite zone d'occupation. Toutefois, sa zone d'occurrence et sa zone d'occupation semblent stables. Son principal habitat naturel dans la région de l'Okanagan, de même que les vieux champs, sont en déclin. De plus, les vieux vergers de pommiers o๠cette souris a déjà été capturée sont convertis en vignobles. La distance de dispersion de cette sous-espèce est limitée, et la probabilité d'une immigration de source externe est petite. Un échantillonnage intensif a révélé l'occurrence de la souris à plus d'un endroit. Une superficie de 63 000 hectares d'habitat convenable à l'espèce est protégée.
