Grant's caribou was described as a small, pale form occupying a limited range at the west end of the Alaska Peninsula and nearby islands. Originally described as Rangifer granti (Allen, 1902), [ 6 ] it was brought under barren-ground caribou as R. arcticus granti [ 7 ] [ 8 ] [ 9 ] because its size and form were closer to the barren-ground type ...
The migratory woodland caribou refers to two herds of Rangifer tarandus (known as caribou in North America) that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or woodland caribou [1] [2] that live in Nunavik, Quebec, and Labrador: the Leaf River caribou herd (LRCH) [3] [4] and the George River caribou herd (GRCH) south of Ungava Bay.
In Alaska, the Western Arctic Caribou herd (490,000 strong in 2004) traverses the Brooks Range in its annual migration. The smaller Central Arctic herd (32,000 in 2002), as well as the 123,000 animal Porcupine Caribou herd, likewise migrate through the Brooks range on their annual journeys in and out of the Arctic National Wildlife Refuge. The ...
A healthy caribou population reflects a healthy boreal ecology. By safeguarding its environment, we can not only save this species and a slew of others, but we can also do our part to combat ...
The populations of caribou are controlled by predators and hunters (who shoot about 22,000 caribou a year). [16] Though in the 1970s there were worries that oil drilling and development in Alaska would harm caribou populations, they seem to have adapted to the presence of humans, and so far there have been few adverse effects.

The barren-ground caribou (Rangifer tarandus groenlandicus; but subject to a recent taxonomic revision) is a subspecies of the reindeer (or the caribou in North America) that is found in the Canadian territories of Nunavut and the Northwest Territories, in northern Alaska and in south-western Greenland.
The fact that caribou migrate long distances means they tend to have longer legs. Depending on the region in which caribou or reindeer live, their physical characteristics will vary slightly.
Most boreal woodland caribou are not migratory. The Labrador caribou, which interbred in ancient times with barren-ground caribou, migrate long distances, while and the Torngat Mountains population of Nunavut, Quebec, Newfoundland and Labrador, and the Atlantic-Gaspésie caribou, move with the seasons to different elevations.
