Assessment rationale/justification
This population of caribou is endemic to Canada. Once thought to be extinct, numbers have recovered to perhaps a quarter of the population historic size. They have not been censused since 1997 and are subject to a high rate of harvest, whose sustainability is questioned by some. They migrate between the mainland and Victoria Island and climate warming or increased shipping may make the ice crossing more dangerous. The population, however, increased substantially over the last three generations and was estimated at about 28000 in 1997.; Cette population de caribou est endémique au Canada. Le nombre d'individus de l'espèce, auparavant considérée comme disparue, s'est rétabli à environ le quart de la population historique. Cette population n'a pas été recensée depuis 1997, elle fait l'objet d'un taux élevé de prises dont la durabilité est remise en question par certains. L'espèce migre entre le continent et l'à®le Victoria, et le réchauffement climatique ou le trafic maritime accru peut rendre la traversée sur les glaces plus dangereuse. Cependant, cette population a considérablement augmenté au cours des trois dernières générations et, en 1997, elle a été estimée à environ 28 000 individus.

History
The original designation considered a single unit that included Peary Caribou, Rangifer tarandus pearyi, and what is now known as the Dolphin and Union population of the Barren-ground Caribou, Rangifer tarandus groenlandicus. It was assigned a status of T; La désignation initiale considérée comme une seule unité comprenait le caribou de Peary, Rangifer tarandus pearyi, et le caribou de la toundra (population Dolphin-et-Union), Rangifer tarandus groenlandicus. Cette unité a été désignée ' menacée ' en avril 1979. Division en 1991 pour permettre la désignation de trois populations distinctes : population de l'à®le Banks (en voie de disparition), population du Haut-Arctique (en voie de disparition) et population du Bas-Arctique (menacée). En mai 2004, les trois désignations de population ont été désactivées, et le caribou de Peary a été évalué séparément du caribou de la toundra (population Dolphin-et-Union), Rangifer tarandus groenlandicus. La population Dolphin-et-Union est composée d'une partie de l'ancienne ' population du Bas-Arctique ' et elle a été désignée ' préoccupante ' en mai 2004.
