Assessment rationale/justification
This land-locked subspecies is endemic to Québec and may number as few as 100 individuals. It inhabits a small series of lakes in northern Québec and is the only subspecies to live entirely in fresh water. The population has declined due to hunting and may still be declining. Proposed hydro-electric development would cause pervasive changes to the habitat.; Cette sous-espèce confinée aux eaux intérieures est endémique au Québec, et sa population pourrait compter aussi peu que 100 individus. Elle habite dans un petit groupe de lacs dans le nord du Québec et est la seule sous-espèce à vivre uniquement en eau douce. La population a connu, et connaà®t peut-être encore, un déclin causé par la chasse. Des aménagements hydroélectriques proposés causeraient des changements considérables à l'habitat.

Assessment rationale/justification
This subspecies has a limited range and has been found at only one location in the past 40 years; this location is isolated from others. Dispersal distance is limited and the population fluctuates. This species is commonly found in owl pellets in the USA, but none have been reported in owl pellets (including burrowing owls) in Suffield or other areas in southeast Alberta, despite substantial sampling. Owl pellet analysis is an excellent means of sampling for these mice.; Cette sous-espèce a une aire de répartition limitée et a été observée à un seul emplacement dans les 40 dernières années; cet emplacement est isolé des autres emplacements. La distance de dispersion est limitée et la taille de la population fluctue. Cette sous-espèce est fréquemment trouvée dans les boulettes de régurgitation des strigidés aux États-Unis, mais n'a pas été rapportée dans celles des strigidés (y compris les Chevêches des terriers) à Suffield, ou à d'autres endroits dans le sud-est de l'Alberta, malgré le nombre important d'échantillons. L'analyse des boulettes de régurgitation des strigidés est un excellent moyen d'échantillonnage de cette souris.

Assessment rationale/justification
The species requires sand dune habitat, which may disappear over the short term (10 years). The area of occupancy is only about 53 km² and only 1000 or fewer individuals are alive at the end of most winters. There is strong evidence for local adaptations of the Canadian population and a rescue effect is extremely unlikely because the nearest population in the United States is 270 km away.; L'espèce nécessite un habitat de dunes qui pourrait disparaà®tre à court terme (10 ans). Sa zone d'occupation est d'environ 53 km² seulement, et tout juste 1 000 individus ou moins survivent à la plupart des hivers. La population canadienne présente des signes convaincants d'adaptation locale, et une immigration de source externe est extrêmement peu probable puisque la population la plus près aux États-Unis se trouve à une distance de 270 km.
