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.
Greenland caribou, found in southwestern Greenland, are "mixed migrators" and many individuals do not migrate; those that do migrate less than 60 km. [171] Unlike the individual-tending mating system, aggregated rutting, synchronized calving and aggregated post-calving of barren-ground caribou, Greenland caribou have a harem-defense mating ...
The timing of migration periods is closely linked to seasonal changes and as unpredictable climate conditions increase, barren-ground caribou must migrate over larger distances. [26] [25] Migration is dictated by the access to easily available lichen. [24] An increased distance of migration places further stress and energy expense on the caribou.
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.
Western Arctic Caribou Herd. Also known as WACH, this herd is one of the largest in Alaska, extending from Wainwright to Kotlik, and they migrate yearly along the Arctic Ocean to their calving ...
Once thought to be hybrids or intergrades with Peary caribou, they are now known to be a barren-ground caribou named after the strait that they migrate across: Dolphin-Union caribou. Further research showed that some R. t. pearyi x groenlandicus hybrids occur on Banks Island and the northwest corner of Victoria Island.
Reindeer, or caribou, are members of the deer family Cervidae. Deer, elk, moose, and wapiti are also members of this family. The distinction between reindeer and caribou depends on where they live.
The caribou are the primary sustenance of the Gwichʼin, a First Nations/Alaska Native people, who traditionally built their communities to align with the caribou's migration patterns. They are also routinely hunted by other indigenous peoples, including the Inupiat , the Inuvialuit , the Hän and the Northern Tutchone .
