The boreal woodland caribou are half again the size (males average 180 kg, up to 272 kg) of barren-ground caribou (males average 110 kg, up to 153 kg) and smaller than the three western montane ecotypes. They have dark colored fur (only the Selkirk mountain caribou is darker) and their boreal forest habitat stretches from Newfoundland to British Columbia in an irregular distribution. 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.
