Assessment rationale/justification
Flying squirrels are small inconspicuous nocturnal forest-dwelling rodents with impressive gliding ability. They are difficult to distinguish from the Northern Flying Squirrel. Dedicated sampling programs have generally revealed greater abundance and range than previously assumed. Its known area of occupancy has expanded. Habitat loss through deforestation and fragmentation of remaining forest may lead to extirpation of some local populations in the southern part of its range in Ontario, but does not currently pose a threat to the persistence of this population. The overall trend in habitat availability is stable or positive. Recent research in Ontario has revealed a much wider range of suitable habitat and reported a substantial range expansion. There is little information on this squirrel from Quebec as there have been no directed surveys for this species. ; Les polatouches sont de petits rongeurs sylvicoles, discrets et nocturnes, qui sont dotés d'une capacité impressionnante pour le planage. Ils sont difficiles à distinguer du grand polatouche. Les programmes d'échantillonnage spécifiques ont généralement révélé une abondance et une aire de répartition plus grandes qu'on ne le croyait. La zone d'occupation connue s'est étendue. La perte d'habitat par suite de la déforestation et de la fragmentation de la forêt résiduelle pourrait se traduire par la disparition de certaines populations locales dans la partie sud de l'aire de répartition en Ontario, mais ne menace pas actuellement la survie de la population. La tendance générale en termes de disponibilité de l'habitat est stable ou positive. De récentes recherches en Ontario ont révélé une superficie beaucoup plus grande de l'habitat convenable pour l'espèce et une expansion considérable de son aire de répartition. Il existe peu d'information sur ce polatouche au Québec étant donné qu'il n'y a pas eu de relevés spécifiques pour cette espèce.
