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. In Nova Scotia, the southern species was first detected in 1971, and until 2001, was only known from seven sites. New recent research located southern flying squirrels in 32 locations and over a much wider area in the southern part of the province than expected. Like a number of species in Nova Scotia, it is at the north of its range and disjunct. Habitat loss through deforestation and fragmentation of intact forest may lead to extirpation of some local populations, but does not currently pose a threat to the species' persistence and the population appears stable.; 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. En Nouvelle-Écosse, l'espèce a été observée pour la première fois en 1971 et, jusqu'en 2001, on ne connaissait sa présence que dans 7 sites. De nouvelles recherches récentes ont décelé la présence de l'espèce dans 32 emplacements, et ce, dans une aire beaucoup plus grande que prévue dans le sud de la province. Tout comme un certain nombre d'espèces en Nouvelle-Écosse, cette espèce est située à  la limite septentrionale de son aire de répartition et est isolée. La perte d'habitat en raison du déboisement et de la fragmentation de forêts intactes pourrait mener à  la disparition de certaines populations locales, mais ne constitue actuellement pas une menace à  la survie de l'espèce, et la population semble stable.
