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.

History
The species was considered a single unit and designated Not at Risk in April 1979. Split into two populations in April 1991 (Prairie population and Northwestern population). The Northwestern population was designated Special Concern in April 1991. Status.; L'espèce a été considérée comme une unité et a été désignée ' non en péril ' en avril 1979. Division en deux populations en avril 1991 (population des Prairies et population du Nord-Ouest). La population du Nord-Ouest a été désignée ' préoccupante ' en avril 1991. Réexamen et confirmation du statut en mai 2002.
