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
The species, found only in the North Atlantic, was heavily reduced by whaling. The total population currently numbers about 322 animals (about 220-240 mature animals), has been decreasing during the last decade, and is experiencing high mortality from ship strikes and entanglement in fishing gear. A sophisticated demographic model gives an estimated mean time to extinction of 208 years.; Cette espèce, qui n'habite que l'Atlantique Nord, a été grandement réduite par la pêche à la baleine. La population totale compte actuellement 322 baleines (environ 220 à 240 animaux adultes), elle a diminué au cours de la dernière décennie et connaà®t une mortalité élevée attribuable aux collisions avec des navires et à l'enchevêtrement dans des engins de pêche. Un modèle démographique perfectionné prévoit à 208 ans le délai moyen de sa disparition de la planète.

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
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
The grizzly bear's habitat is at risk from expanding industrial, residential and recreational developments. Habitat and population fragmentation are underway in the southern part of the bear's distribution. The life history characteristics of this bear make it particularly sensitive to human-caused mortality (including hunting, poaching, accidents and nuisance kills). Its behavior frequently brings it into conflict with people, leading to increased mortality where human activities expand. It has disappeared from a substantial part of its historic range, but there are still over 26,000 grizzly bears in Canada. The grizzly bear's area of occupancy has not decreased substantially over the past 20 years. The future of several populations that are either completely or mostly isolated is highly uncertain and dependent on conservation.; L'habitat de l'ours grizzli est en péril en raison des aménagements industriels, domiciliaires et récréatifs croissants. La fragmentation de l'habitat et de la population est en cours dans le sud de l'aire de répartition de l'ours. Les caractéristiques du cycle biologique de cet ours le rendent particulièrement vulnérable à la mortalité causée par les humains (dont la chasse, le braconnage, les accidents et les prises d'ours nuisibles). Son comportement le met souvent en conflit avec les personnes, ce qui entraà®ne un taux de mortalité accru lorsque les activités anthropiques s'étendent. L'espèce a disparu d'une partie importante de son aire de répartition historique, mais il y a encore plus de 26 000 ours grizzlis au Canada. La zone occupée par l'ours grizzli n'a pas diminué de manière importante au cours des 20 dernières années. L'avenir de plusieurs populations qui sont complètement ou grandement isolées est très incertain et dépend de la conservation.

Assessment rationale/justification
Blue whales off the coast of British Columbia are likely part of a population based in the northeastern Pacific. The population was reduced by whaling. The rarity of sightings (visual and acoustic) suggests their numbers are currently very low (significantly less than 250 mature individuals). Threats for blue whales along the coast of British Columbia are unknown, but may include ship strikes, pollution, entanglement in fishing gear, and long-term changes in climate (which could affect the abundance of their zooplankton prey).; Les rorquals bleus au large de la cà´te de la Colombie-Britannique font probablement partie d'une population établie dans la partie septentrionale du Nord-Est de l'océan Pacifique. Leur population a été réduite en raison de la chasse à la baleine. La rareté des observations (visuelles et acoustiques) semble indiquer que leur nombre est actuellement très faible (beaucoup moins que 250 individus matures). Les menaces qui pèsent sur les rorquals bleus le long de la cà´te de la Colombie-Britannique sont inconnues, mais elles peuvent inclure les collisions avec des navires, la pollution, l'enchevêtrement dans des engins de pêche et les changements climatiques à long terme (qui pourraient avoir une incidence sur l'abondance de leur proie, le zooplancton).

Assessment rationale/justification
Whaling reduced the original population. There are fewer than 250 mature individuals and strong indications of a low calving rate and a low rate of recruitment to the studied population. Today, the biggest threats for this species come from ship strikes, disturbance from increasing whale watch activity, entanglement in fishing gear, and pollution. They may also be vulnerable to long-term changes in climate, which could affect the abundance of their prey (zooplankton).; La chasse à la baleine a réduit la population initiale. Il existe moins de 250 individus matures, et il y a de fortes indications d'un taux faible de mise bas et d'un taux faible de recrutement au sein de la population étudiée. Actuellement, les plus grandes menaces pour cette espèce proviennent des collisions avec des navires, de la perturbation causée par l'activité croissante de l'observation des baleines, de l'enchevêtrement dans les engins de pêche et de la pollution. Les baleines peuvent aussi être vulnérables aux changements climatiques à long terme, ce qui pourrait avoir une incidence sur l'abondance de leur proie (zooplancton).
