Assessment rationale/justification
In Canada, this species occurs in the intermontane grasslands and ponderosa pine woodlands of southern British Columbia. It is a distinctively coloured bat that is unmistakable to identify. Unlike any other Canadian species of bat, its echolocation calls are within the range of human hearing. It roosts in crevices in large cliff faces. It is considered the easiest to count and best censused species of bat in Canada. Population estimates, based on relatively good census effort, suggests that there are fewer than 1000 adults. At this time, numbers appear to be stable, and there are relatively few threats to populations or habitats. Perhaps the biggest threat to this species is its small population size. Use of pesticides on its insect prey, loss of foraging habitat, and disturbance at roosting sites by rock climbers are potential threats. Rescue may be possible from neighbouring populations in the United States, however, movements of individuals between Canadian and US populations are not documented.; Au Canada, cette espèce se trouve dans les terres herbeuses et les terrains boisés de pins ponderosa du sud de la Colombie-Britannique. Il s'agit d'une chauve-souris de couleur distincte, ce qui permet de l'identifier sans aucun doute. Contrairement à toute autre espèce de chauve-souris au Canada, les cris d'écolocation de cette espèce peuvent être entendus par l'être humain. Cette espèce se repose dans les crevasses de grandes falaises. Cette espèce est considérée comme l'espèce de chauve-souris la plus recensée et la plus facile à dénombrer au Canada. Les estimations de populations, fondées sur des recensements relativement fiables, suggèrent qu'il existe moins de 1000 adultes. à‚¬ l'heure actuelle, les nombres semblent stables, et relativement peu de menaces pèsent sur les populations ou les habitats. La plus grave menace pour cette espèce est possiblement la petite taille de sa population. L'utilisation de pesticides sur des insectes qui sont ses proies, la perte de son habitat d'alimentation et la perturbation dans ses sites de repos par des alpinistes sont des menaces possibles. Une immigration de populations avoisinantes aux États-Unis est possible; cependant, le déplacement des individus entre les populations canadiennes et américaines n'a pas été documenté.

Assessment rationale/justification
This species is rarely reported in its Canadian range. There are, however, a few sites in the Okanagan Valley where they regularly can be captured during the summer. There is a lack of data about the extent of its Canadian range and the habitat that is important for foraging and roosting. We also do not know the population size or trends, nor any key demographic characteristics, such as population structure, reproduction or survival rates. It is not known if this species overwinters in Canada or migrates south for the winter; however, there are maternity colonies recorded in Canada.; Cette espèce est rarement observée dans son aire de répartition canadienne. Il existe cependant, quelques sites dans la vallée de l'Okanagan o๠l'espèce peut être régulièrement capturée en été. Il existe un manque de données sur l'étendue de son aire de répartition au Canada et sur l'habitat qui est important pour son alimentation et son repos. Nous ne connaissons pas non plus la taille ou les tendances de la population, ni les caractéristiques démographiques clés, telles que la structure de la population et les taux de reproduction ou de survie. Nous ne savons pas si cette espèce hiverne au Canada ou si elle migre vers le sud en hiver; cependant, des maternités coloniales ont été trouvées au Canada

Assessment rationale/justification
The population overwinters in Baffin Bay and west Greenland and may consist of two distinct populations. It is heavily hunted in west Greenland. However, most of the population winters in Baffin Bay and the high Arctic where it is not hunted. Hunting pressure in Canadian waters is low in summer.; La population hiverne dans la baie de Baffin et à l'ouest du Groenland et pourrait être composée de deux populations distinctes. Elle est chassée intensivement dans l'ouest du Groenland. Cependant, la plupart des individus de la population hivernent dans la baie de Baffin et le Haut-Arctique, o๠ils ne sont pas chassés. Les pressions exercées par la chasse dans les eaux canadiennes sont faibles l'été.

The population was reduced by at least 50% and continues to decline. Overhunting continues throughout its summer and migratory range. Mathematical models predict that it will likely disappear under present hunting levels in less than 10 to 15 years. Concerns have been expressed about habitat degradation of estuaries by hydroelectric projects, and by small vessel traffic disturbance.; La population a été réduite d'au moins 50 p. 100 et le déclin continue. La chasse excessive se poursuit dans toute son aire de répartition estivale et migratoire. Selon des modèles mathématiques, si les prises restent à leur niveau actuel, la population disparaà®tra vraisemblablement dans moins de 10 à 15 ans. Des préoccupations ont été exprimées au sujet de la dégradation de l'habitat des estuaires provoquée par les installations hydroélectriques et les perturbations dues au trafic des petites embarcations.

Assessment rationale/justification
Numbers of belugas using Cumberland Sound have declined by about 1500 individuals between the 1920s and present. The population decline is believed to have been caused by hunting by the Hudson Bay Company into the 1940s and by the Inuit until 1979. Hunting has been regulated since the 1980s. Current quotas (41 in 2003) appear to be sustainable. Concerns have been raised about increased small vessel traffic and the associated noise of outboard motors, as well as fishery removals of Greenland halibut, a food of belugas.; Le nombre de bélugas utilisant la baie de Cumberland a connu un déclin d'environ 1500 individus entre les années 1920 et aujourd'hui. La chasse par la Compagnie de la Baie d'Hudson jusque dans les années 1940 et la chasse par les Inuits jusqu'en 1979 semblent être la cause du déclin. La chasse est réglementée depuis les années 1980. Les quotas actuels (41 en 2003) semblent être durables. Des préoccupations concernant le trafic accru de petites embarcations et le bruit des moteurs hors bord qui leur est associé, ainsi que la pêche au flétan noir, un aliment consommé par le béluga, ont été soulevées.

Assessment rationale/justification
The population was severely reduced by hunting, which continued until 1979. High contaminant loads may have also contributed to the population decline. Aerial surveys since 1973 suggest that the decline has ceased, but do not provide clear evidence of a significant increase in numbers. Levels of many contaminants remain high in beluga tissues. The whales and their habitat are threatened by contaminants, vessel traffic, and industrialization of the St. Lawrence watershed.; La population a été grandement réduite par la chasse, laquelle a eu lieu jusqu'en 1979. Des charges élevées de contaminants ont peut-être aussi contribué au déclin de la population. Les relevés aériens effectués depuis 1973 laissent croire que le déclin a cessé, mais ils ne fournissent pas de preuves claires d'une augmentation importante des effectifs. Les niveaux de nombreux contaminants demeurent élevés dans les chairs du béluga. Les baleines et leur habitat sont menacés par les contaminants, le trafic maritime et l'industrialisation du bassin hydrographique du fleuve Saint Laurent.

Assessment rationale/justification
Estimated total population size exceeds 13,000 mature individuals. Declines have been reported in Alberta and parts of British Columbia and Ontario. A distinct subspecies may be extirpated from Vancouver Island. Many pelts used locally are not included in official statistics, and harvest levels may be underreported. There is no evidence, however, of a decline in harvest. There are no data on overall population trends other than those provided by local knowledge and harvest monitoring programs. This species' habitat is increasingly fragmented by industrial activity, especially in the southern part of its range, and increased motorized access will increase harvest pressure and other disturbances. The species has a low reproductive rate and requires vast secure areas to maintain viable populations.; La population totale estimée dépasse les 13 000 individus matures. Des déclins ont été signalés en Alberta et dans certaines régions de la Colombie-Britannique et de l'Ontario. Une sous-espèce distincte pourrait avoir disparu de l'à®le de Vancouver. De nombreuses pelleteries utilisées à l'échelle locale ne sont pas incluses dans les statistiques officielles, et les taux de prises pourraient avoir été sous-déclarés. Cependant, il n'y a aucune preuve d'un déclin des prises. Il n'existe aucune donnée sur les tendances démographiques générales autre que celles fournies par les connaissances locales et les programmes de surveillance des prises. L'habitat de cette espèce est de plus en plus fragmenté par l'activité industrielle, surtout dans la partie sud de son aire de répartition; de plus, l'accès accru par véhicule motorisé augmentera la pression relative aux prises et d'autres perturbations. L'espèce a un taux de reproduction faible et nécessite de vastes aires protégées pour maintenir des populations viables.

Assessment rationale/justification
Although heavily reduced by whaling, this well-studied population seems to have regrown to at least a substantial proportion of its pre-whaling size. The population does face threats (including entanglement in fishing gear, habitat degradation on breeding grounds, possible resumption of commercial whaling), but neither the North Atlantic population, nor any of its feeding sub-populations, is at risk from current activity levels, or levels that may reasonably be foreseen in the next few years.; Bien que la pêche à la baleine ait beaucoup réduit son effectif, cette population bien étudiée semble avoir augmenté au moins à une proportion importante de sa taille avant la pêche. La population subit des menaces (y compris l'enchevêtrement dans des engins de pêche, la dégradation de l'habitat dans les aires de reproduction, la reprise éventuelle de la pêche commerciale à la baleine), mais ni la population de l'Atlantique Nord ni aucune de ses sous-populations d'alimentation n'est menacée par les niveaux actuels d'activité ou les niveaux qui peuvent être raisonnablement prévus pour les quelques prochaines années.

Assessment rationale/justification
They appear to be particularly sensitive to human activities, and are prone to becoming entrapped and killed in fishing nets. They are a short lived shy species that are now rarely seen at the highly developed areas of Victoria and Haro Strait. Continued development and use of its prime habitat by humans are some of the main threats. They are displaced by underwater noise, and could be affected by contaminants in their food chain.; Cette espèce semble particulièrement vulnérable aux activités de l'être humain, et a tendance à s'enchevêtrer dans des engins de pêche et à mourir. Il s'agit d'une espèce timide dont la durée de vie est courte, qui est maintenant rarement observée dans les régions grandement aménagées de Victoria et du détroit de Haro. L'aménagement continu et l'utilisation de l'habitat principal de cette espèce par les humains constituent certaines des principales menaces. Les bruits sous-marins font fuir les marsouins, et ces derniers pourraient être touchés par les contaminants présents dans leur chaà®ne alimentaire.
