Le caribou aux TNO

Le caribou de Dolphin-et-Union

Dolphin and Union caribou look similar to Peary caribou but are larger and slightly darker with grey velvet covering their antlers. The population was considered as Peary caribou in the past but recent genetic studies indicate the animals are distinct from both barren-ground and Peary caribou.

Dolphin and Union caribou are restricted to Victoria Island and the nearby mainland coasts of Nunavut and the NWT. They cross the frozen sea ice between Victoria Island and the mainland twice a year.

Selon les estimations de 1997, 2007, 2015 et 2018, la population était supérieure à 30 000 individus en 1997, mais de seulement 18 000 en 2015, puis de seulement 4 000 en 2018. D’après les savoirs traditionnels dénés et inuits, une tendance à la baisse et des changements de répartition ont été observés chez les caribous de Dolphin-et-Union. Le taux de mortalité du caribou de Dolphin-et-Union due à la noyade (glace trop mince), à la prédation et à la chasse est assez élevé.

Dolphin and Union caribou are listed as a species of ‘Special Concern' under both the federal Species at Risk Act and the territorial Species at Risk (NWT) Act. In 2017, COSEWIC re-assessed the status of Dolphin and Union caribou as Endangered in Canada.

A management plan for Dolphin and Union caribou in the NWT and Nunavut was completed in 2018.
