Migratory woodland caribou

The migratory woodland caribou refer to two herds of caribou, that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or Woodland caribou. that exist in Nunavik, Québec and Labrador, the Leaf River Caribou Herd (LRCH) and the George River caribou herd (GRCH), south of Ungava Bay. Rangifer tarandus caribou is further divided into three ecotypes: – migratory barren-ground ecotype, the mountain ecotype or woodland (montane) and the forest-dwelling ecotype (boreal caribou). The "George River herd which morphologically and genetically belong to the woodland caribou subspecies, at one time represented the largest caribou herd in the world and migrating thousands of kilometers from boreal forest to open tundra, where most females calve within a three week period. This behaviour is more like barren-ground caribou subspecies." They argued that "understanding ecotype in relation to existing ecological constraints and releases may be more important than the taxonomic relationships between populations." The migratory George River caribou herd travel thousands of kilometers moving from wintering grounds to calving grounds near the Inuit hamlet of Kangiqsualujjuaq, Nunavik (also known as George River hamlet). In Nunavik, northern Québec and Labrador the caribou population varies considerably with their numbers peaking in the later decades of each of the 18th, 19th and 20th centuries. In 1984, about 10000 caribou of the George River herd drowned during their bi-annual crossing of the Caniapiscau River during the James Bay hydro project flooding operation. The most recent decline at the turn of the 20th century caused much hardship for the Inuit and Cree communities of Nunavik, who hunt them for subsistence.
