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.

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.

Assessment rationale/justification
There is no identifiable threat to the subspecies in the eastern North Pacific (there is no whaling; number of deaths from entanglement in fishing gear and ship strikes is not thought to be high enough to cause concern). There is considerable potential for rescue - mainly from United States waters to the north and south; individuals occurring in inshore waters in Canada could constitute a naturally small population.; Il n'y a pas de menace identifiable envers la sous-espèce dans l'est du Pacifique Nord (il n'y a pas de chasse à la baleine; les mortalités causées par l'enchevêtrement dans les engins de pêche et les collisions avec les navires ne sont pas considérées assez nombreuses pour être préoccupantes). Il y a une possibilité élevée d'immigration de source externe - principalement des eaux des États-Unis au nord et au sud; les individus présents dans les eaux cà´tières du Canada pourraient constituer une petite population naturelle.

Assessment rationale/justification
Calculations by the Species Specialist Subcommittee, based on survey estimates for some areas and informed judgements for others, suggest a total population in the order of 15,000 (6000 West Greenland, 1000 Gulf of St. Lawrence, 3000 Scotian Shelf, probably at least 5000 Newfoundland/Labrador = 15,000). Although the hunt in West Greenland may involve the same stock that occurs in eastern Canadian waters, recent and current removals are likely sustainable, given that the annual catch quota is 175, representing an offtake of ca. 0.01, which does not exceed replacement. Human-caused mortality from other potential threats does not exceed replacement.; Des calculs effectués par le Sous-comité de spécialistes des espèces, reposant sur des dénombrements estimatifs pour certaines aires et sur des opinions éclairées pour d'autres, indiquent que la population totale serait de l'ordre de 15 000 (6 000 individus dans l'ouest du Groenland, 1 000 individus dans le golfe du Saint-Laurent, 3 000 individus sur le plateau néo-écossais et probablement au moins 5 000 individus à Terre-Neuve-et-Labrador, pour un total de 15 000). Bien que la chasse dans l'ouest du Groenland puisse toucher la même population que celle des eaux de l'est du Canada, le nombre de captures récentes et actuelles semble durable, étant donné que le maximum annuel de prises est de 175, ce qui représente un coefficient d'environ 0,01 et n'excède pas le seuil de remplacement. La mortalité attribuable à l'humain par d'autres menaces potentielles ne dépasse pas le seuil de remplacement.

Assessment rationale/justification
The population that breeds on the Pribilof Islands in the Bering Sea feeds in, and migrates through, British Columbia waters. This population numbered about 629,000 animals in 2004. Although still relatively large, the population, as inferred from pup counts, has declined by 50-60% over three generations (1974-2004). The rate of decline has been particularly rapid since 1998. Trends in counts of adult males from 1974-2004 are confounded by response to the cessation, in 1984, of the selective commercial harvesting of sub-adult males in 1984. These counts have declined rapidly and inexplicably since 1992. The reasons for the population decline are unknown. Entanglement in marine debris, disturbance, pollution, and environmental changes, possibly including a regime shift in the Bering Sea and North Pacific ecosystems, are thought to be contributing factors. Little is known about possible limiting factors in British Columbia and other regions where fur seals forage during their annual migration.; La population qui se reproduit sur les à®les Pribilof, dans la mer de Béring, se nourrit et migre dans les eaux de la Colombie-Britannique. Cette population comptait environ 629 000 individus en 2004. Bien que ce nombre demeure relativement élevé, la population, telle qu'estimée à partir des dénombrements des petits, a diminué de 50 à 60 % sur trois générations (de 1974 à 2004). Le taux de déclin est particulièrement rapide depuis 1998. Les tendances dans les nombres de mà¢les adultes entre 1974 et 2004 sont brouillées par la réaction à la suspension, en 1984, de la prise sélective commerciale des jeunes adultes mà¢les. Ces nombres diminuent de façon rapide et inexplicable depuis 1992. Les raisons du déclin de la population sont inconnues. L'enchevêtrement dans les débris marins, le dérangement, la pollution et les changements environnementaux, incluant possiblement un changement du régime dans les écosystèmes de la mer de Béring et du Pacifique Nord, sont considérés comme des facteurs contributifs. Les facteurs limitatifs possibles sont peu connus en Colombie-Britannique et dans d'autres régions o๠les otaries à fourrure cherchent de la nourriture pendant leur migration annuelle.

Assessment rationale/justification
It is highly likely that this shrew is more widespread and abundant than presently believed. Although the occurrence of presumed preferred habitat is restricted and isolated in the landscape, it is not at risk. The species appears to be widespread in talus habitats throughout its range. Recent information questions the taxonomic status of this shrew. Whereas it may well be a subspecies of Sorex dispar, when the original designation was made, it was considered a Canadian endemic species. ; Il est fort probable que cette musaraigne soit plus répandue et abondante qu'on ne le croit actuellement. Bien que son présumé habitat de prédilection soit restreint et isolé dans le paysage, il n'est pas en péril. L'espèce semble répandue dans les habitats de talus dans l'ensemble de son aire de répartition. De nouveaux renseignements remettent en question le statut taxinomique de cette musaraigne. Celle-ci pourrait bien être une sous-espèce de Sorex dispar. Lorsque la désignation initiale a été effectuée, elle était considérée comme une espèce endémique au Canada.

Assessment rationale/justification
This small beaked whale is endemic to the North Atlantic Ocean where it is found mainly in deep, offshore temperate to subarctic waters. Little is known about its biology, fine-scaled distribution, and abundance. It belongs to a family of whales (Ziphiidae) in which acute exposure to intense sounds (especially from military sonar, but also from seismic operations) has led to serious injury and mortality. Seismic operations are currently widespread and military activities involving the use of mid- and low-frequency sonar likely occur at least occasionally in the habitat of this species off Canada's East Coast. Although there is no direct evidence that such sound sources have affected this species, there is strong evidence for lethal effects on individuals of related species. Thus there is reasonable cause for concern about the potential effects on individuals of this species. The potential population-level impacts of this type of mortality are unknown. ; Cette petite baleine à bec est endémique à l'océan Atlantique Nord o๠elle se trouve principalement dans les eaux profondes tempérées à subarctiques au large des cà´tes. Sa biologie, sa répartition à petite échelle et son abondance sont peu connues. L'espèce appartient à une famille de baleines, les Ziphiidés, chez laquelle une exposition aiguà« au bruit intense (en particulier aux sonars militaires, mais également aux activités sismiques) a été à l'origine de graves blessures et de mortalités. Les activités sismiques sont actuellement fréquentes et les activités militaires comportant l'utilisation de sonars à moyenne et à basse fréquence se produisent probablement, du moins occasionnellement, dans l'habitat de cette espèce au large de la cà´te est du Canada. Aucune conséquence de ces sources de bruit sur cette espèce n'a été démontrée directement. Toutefois, les effets létaux des sources de bruit ont été largement démontrés chez des individus d'espèces apparentées. Il est donc raisonnable de présumer l'existence d'effets potentiels similaires chez les individus de cette espèce. Les impacts potentiels au niveau de la population de ce type de mortalité ne sont pas connus.

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.

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.
