Boreal Caribou live throughout the boreal forest of the NWT in small groups and prefer to stay within the forest year-round. During calving, Boreal Caribou females space themselves out throughout the range, often where access is difficult for predators. Boreal Caribou need large areas of intact habitats so they can spread out to avoid predators.
Boreal Caribou use almost all forested areas east of the Mackenzie Mountains. They tend to spend time in mature coniferous forests with plentiful lichens. Ridges, swamps, burned areas and meadows are also important in spring and summer.
Boreal Caribou are well adapted to their northern environment. Their large, well-insulated hooves prevent sinking when traveling on wetlands and snow and are adapted for digging through snow for food.
Boreal Caribou are sometimes called the "grey ghosts of the forest" beause they are secretive and difficult to find, and when disturbed they usually disappear quickly into the forest.
