A number of wildlife species threatened or endangered with extinction can be found in the Canadian Boreal forest, including woodland caribou, American black bear, grizzly bear and wolverine. Habitat loss, mainly due to logging, is the primary cause of decline for these species.
Due to climate, carnivorous diets are inefficient means of obtaining energy; energy is limited, and most energy is lost between trophic levels. Predatory birds (owls and eagles) and other smaller carnivores, including foxes and weasels, feed on the rodents. Larger carnivores, such as lynx and wolves, prey on the larger animals. Omnivores, such as bears and raccoons are fairly common, sometimes picking through human garbage.
