Life Of Siberian Reindeer Herders, Yamal, Russia.

- Migratory Woodland Caribou (R. tarandus caribou), or Forest Caribou, once found in the North American taiga (boreal forest) from Alaska to Newfoundland and Labrador and as far south as New England, Idaho, and Washington. Woodland Caribou have disappeared from most of their original southern range and are considered threatened where they remain, with the notable exception of the Migratory Woodland Caribou of northern Quebec and Labrador, Canada. The name of the Cariboo district of central British Columbia relates to their once-large numbers there, but they have almost vanished from that area in the last century. A herd is protected in the Caribou Mountains in Alberta. The above quoted range includes R. tarandus caboti (Labrador Caribou), R. tarandus osborni (Osborn's Caribou – from British Columbia) and R. tarandus terraenovae (Newfoundland Caribou). Based on a review in 1961, these were considered invalid and included in R. tarandus caribou, but some recent authorities have considered them all valid, even suggesting that they are quite distinct. An analysis of mtDNA in 2005 found differences between the caribous from Newfoundland, Labrador, south-western Canada and south-eastern Canada, but maintained all in R. tarandus caribou.
- †Queen Charlotte Islands Caribou (R. tarandus dawsoni) from the Queen Charlotte Islands was believed to represent a distinct subspecies. It became extinct at the beginning of the 20th century. However, recent DNA analysis from mitochondrial DNA of the remains from those reindeer suggest that the animals from the Queen Charlotte Islands were not genetically distinct from the Canadian mainland reindeer subspecies.
