Assessment rationale/justification
There are only about 450 mature individuals in a single Canadian population with a range of 13 km², adjacent to a small area of occupied habitat in the USA. Threats to the population include trapping by pest removal companies and property owners. The habitat has been degraded through fragmentation and urbanization. There is no evidence of decline over the last 10 years. It is uncertain whether immigration across the international border may rescue the Canadian population.; Il existe seulement environ 450 individus matures dans une seule population canadienne ayant une aire de répartition de 13km², adjacente à une petite zone d'habitat occupée aux États-Unis. La population est menacée par le piégeage effectué par les entreprises d'extermination des espèces nuisibles et les propriétaires fonciers. L'habitat s'est dégradé par suite de sa fragmentation et de l'urbanisation. Il n'y a aucune preuve de déclin depuis les dix dernières années. On ne sait pas si l'immigration d'individus provenant des États-Unis peut aider à rétablir la population canadienne.

Assessment rationale/justification
This was one of the most abundant species sought by whalers off the British Columbia coast (with over 4000 individuals killed) and was also commonly taken in other areas of the eastern North Pacific. Sei whales have not been reported in British Columbia since whaling ended and may now be gone. There are few, if any, mature individuals remaining in British Columbia waters; and there is clear evidence of a dramatic decline caused by whaling and no sign of recovery.; Il s'agissait de l'une des espèces les plus abondantes recherchées par les pêcheurs de baleines au large de la cà´te de la Colombie-Britannique (avec plus de 4 000 individus abattus), et elle était aussi souvent prise dans d'autres zones de l'Est du Pacifique Nord. Des rorquals boréaux n'ont pas été signalés en Colombie-Britannique depuis la fin de la pêche à la baleine. Il y a, s'il en reste, peu d'individus matures dans les eaux de la Colombie-Britannique, et il y a des preuves manifestes d'un important déclin causé par la pêche à la baleine et aucun signe de rétablissement.

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 situation for this species is generally similar to that for any species of bat that occurs in Canada. There are no data about populations sizes, populations trends, or patterns of reproduction (it is not known if females bear young annually; age at sexual maturity is unknown), and there are only scattered records documenting occurrence and patterns of distribution. Furthermore, there is a lack of information about patterns of habitat use (roosting, foraging) or data about migration. Uncertainty about the taxonomic status of this species further complicates the matter. It is unknown if it is a distinct taxon. It is unknown if this is a distinct population.; La situation de cette espèce est de façon générale semblable à celle de toutes les espèces de chauves-souris présentes au Canada. Il n'existe aucune donnée au sujet de la taille des populations, de leurs tendances ou de leurs habitudes de reproduction (on ne sait si la femelle a des portées annuelles; l'à¢ge de la maturité sexuelle est inconnu), et seulement des enregistrements dispersés documentent la présence et les tendances de distribution. En outre, il y a un manque d'information sur les habitudes d'utilisation de l'habitat (repos, alimentation) et un manque de données sur la migration. L'incertitude au sujet du statut taxinomique de cette espèce complique davantage les choses. On ne sait s'il s'agit d'un taxon distinct ni s'il s'agit d'une population distincte.

Assessment rationale/justification
Heavily reduced by whaling, the North Pacific population appears to be increasing. The number of animals that use British Columbia waters is probably in the low hundreds. The high-level of feeding ground fidelity suggests that if animals are exterminated from a particular area, it is unlikely that the area will be rapidly repopulated from other areas. Two extirpated British Columbia populations have shown no sign of rescue. Humpbacks are occasionally entangled in fishing gear, though the number entangled is not thought to threaten or limit the population. In summary, humpback whales that use British Columbia waters appear to be well below historical numbers and have not returned to some portions of their former range.; La chasse a beaucoup réduit ses effectifs, mais la population du Pacifique Nord semble être en croissance. Le nombre d'individus qui utilisent les eaux de la Colombie Britannique se situe probablement à quelques centaines. La fidélité élevée aux aires d'alimentation indique que si les animaux sont exterminés dans une aire particulière, il est peu probable que l'aire sera rapidement repeuplée à partir d'autres zones. Deux populations disparues de la Colombie Britannique n'ont pas manifesté de signes d'immigration de source externe. Les rorquals s'enchevêtrent à l'occasion dans des engins de pêche, bien que l'on ne croie pas que le nombre d'animaux enchevêtrés menace ou limite la population. En bref, les rorquals à bosse qui utilisent les eaux de la Colombie-Britannique semblent être bien en dessous des nombres historiques et n'ont pas réoccupé certaines parties de leur ancienne aire de répartition.

Assessment rationale/justification
This species is seen off Nova Scotia and Newfoundland. However, data are lacking to determine the degree of depletion caused by whaling, or to assess current population size, or to determine whether the population has recovered in any way since whaling ended. The effects of current threats, especially oil and gas exploration and development, are unknown. There is also uncertainty regarding possible population substructure.; Cette espèce est observée au large de la Nouvelle-Écosse et de Terre-Neuve. Cependant, il n'y a pas suffisamment de données permettant de déterminer l'ampleur de l'appauvrissement provoqué par la pêche à la baleine ou d'évaluer la taille actuelle de la population ou de déterminer si la population s'est rétablie de quelque manière que ce soit depuis la fin de la pêche à la baleine. Les incidences des menaces actuelles, notamment de l'exploration et de la mise en valeur du pétrole et du gaz, sont inconnues. La sous-structure démographique possible est également incertaine.

Assessment rationale/justification
There have been no verified reports of this species in Québec or Labrador for about 25 years but there are unconfirmed reports almost every year. Any remaining population would be extremely small and therefore at high risk of extinction from stochastic events such as incidental harvest. The apparent lack of recovery despite the recent high local abundance of caribou suggests that this population may be extirpated.; Il n'y a aucune observation vérifiée de cette espèce au Québec ou au Labrador depuis environ 25 ans, mais il y a des observations non confirmées presque chaque année. Toute population restante serait extrêmement petite et donc en danger élevé de disparition à cause de phénomènes stochastiques tels que les prises accessoires. L'absence apparente de rétablissement, malgré une grande abondance récente de caribous à l'échelle locale, indique que cette population pourrait avoir disparu du Canada.

Assessment rationale/justification
This was one of the most abundant species sought by whalers off the British Columbia coast (with over 4000 individuals killed) and was also commonly taken in other areas of the eastern North Pacific. Sei whales have not been reported in British Columbia since whaling ended and may now be gone. There are few, if any, mature individuals remaining in British Columbia waters; and there is clear evidence of a dramatic decline caused by whaling and no sign of recovery.; Il s'agissait de l'une des espèces les plus abondantes recherchées par les pêcheurs de baleines au large de la cà´te de la Colombie-Britannique (avec plus de 4 000 individus abattus), et elle était aussi souvent prise dans d'autres zones de l'Est du Pacifique Nord. Des rorquals boréaux n'ont pas été signalés en Colombie-Britannique depuis la fin de la pêche à la baleine. Il y a, s'il en reste, peu d'individus matures dans les eaux de la Colombie-Britannique, et il y a des preuves manifestes d'un important déclin causé par la pêche à la baleine et aucun signe de rétablissement.
