Assessment rationale/justification
There are only three breeding locations in British Columbia. Although the population is increasing, they are sensitive to human disturbance while on land. Threats include the possibility of acute oil spills. There are unexplained declines in other populations to the north and west of British Columbia.; Il n'y a que trois endroits de reproduction en Colombie-Britannique. Bien que la population augmente, cette espèce est vulnérable aux perturbations par les humains lorsqu'elle est sur terre. Parmi les menaces, il y a la possibilité de déversements graves d'hydrocarbures. D'autres populations, au nord et à  l'ouest de la Colombie-Britannique, connaissent des déclins inexpliqués.

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.

A widespread species whose population density varies regularly over 10-11 year cycles, following the cycles in abundance of its main prey, the snowshoe hare. Although numbers have declined in parts of its southern range, notably in New Brunswick and Nova Scotia, overall the Canadian population is secure.; Une espèce répandue dont la densité des populations varie régulièrement au cours de cycles de 10 à  11 ans, suivant les cycles d'abondance de sa principale proie, le lièvre d'Amérique. Même si le nombre d'individus a connu un déclin dans des parties de son aire de répartition méridionale, particulièrement au Nouveau-Brunswick et en Nouvelle-Écosse, la population canadienne dans son ensemble n'est pas en péril.

Assessment rationale/justification
The Baffin Bay population appears to be large (~45,000), although there is uncertainty about numbers, trends, life history parameters, and levels of sustainable hunting. There is similar uncertainty about the much smaller Hudson Bay population (~2,100 mature individuals). Hunting for maktak and the commercially valuable tusk ivory represents the most consistent threat to narwhals. Potential effects of changes in ice coverage caused by climate trends are unknown. The Hudson Bay population could decline by 30% in 30 years if hunting is not closely regulated. Similarly, the Baffin Bay population could be affected if hunting in Greenland is not effectively managed. Numbers removed by hunting increased during the 1990s. Community-based management is monitoring hunting and is attempting to regulate removals. Reliable information about numbers that are killed and not recovered is difficult to obtain.; La population de la baie de Baffin semble grande (environ 45 000 individus), bien qu'il y ait des incertitudes quant au nombre d'individus, aux tendances et à  certains paramètres du cycle biologique, ainsi qu'au nombre de prises pour assurer une chasse à  des niveaux durables. Il y a aussi des incertitudes pour ce qui est de la population beaucoup plus petite de la baie d'Hudson (environ 2100 individus matures). La chasse pour le maktak et l'ivoire, qui a une grande valeur sur le marché, représente une menace des plus constantes pour le narval. Les effets éventuels du changement dans la couverture de glace, causé par les tendances climatiques, sont inconnus. La population de la baie d'Hudson pourrait connaà®tre un déclin de 30 p. 100 en 30 ans si la chasse ne fait pas l'objet d'une réglementation stricte. De façon semblable, la population de la baie de Baffin pourrait être touchée par la chasse au Groenland si elle n'est pas gérée efficacement. Le nombre d'individus tués par la chasse a augmenté au cours des années 1990. La gestion par les communautés permet de surveiller la chasse et de trouver des solutions pour réglementer les prises. Une information fiable sur le nombre d'individus tués et non récupérés est difficile à  obtenir.

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 subspecies has a limited range, and a small extent of occurrence and area of occupancy. However, the extent of occurrence and area of occupancy appear to be constant. Its principal native habitat in the Okanagan as well as old fields is declining. Furthermore, old apple orchards where the mouse has been caught are being converted to vineyards. Dispersal distance is limited and the likelihood of rescue effect is small. Extensive sampling has revealed the occurrence of the mouse at more localities. 63,000 hectares of suitable habitat is protected.; Cette sous-espèce a une aire de répartition limitée, une petite zone d'occurrence et une petite zone d'occupation. Toutefois, sa zone d'occurrence et sa zone d'occupation semblent stables. Son principal habitat naturel dans la région de l'Okanagan, de même que les vieux champs, sont en déclin. De plus, les vieux vergers de pommiers o๠cette souris a déjà  été capturée sont convertis en vignobles. La distance de dispersion de cette sous-espèce est limitée, et la probabilité d'une immigration de source externe est petite. Un échantillonnage intensif a révélé l'occurrence de la souris à  plus d'un endroit. Une superficie de 63 000 hectares d'habitat convenable à  l'espèce est protégée.

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.
