Why Are Caribou Endangered?
Woodland caribou used to occur in the northern forests of New England, the Great Lake States and the Inland Northwest. They are now restricted to the Selkirk Mountains. Recent surveys indicate that there are approximately 40 animals in the recovery area. Over-hunting in the early 20th century caused a massive decline in their population. Timber harvests and large wildfires caused a loss of habitat and forest fragmentation. Caribou are less resilient than either deer or elk and have very specific habitat needs. Female caribou do not breed until they are 3 1/2 years old, and produce only one calf per year. This reproductive rate is among the lowest in the deer family. Calves are especially vulnerable to predation. Many of them die of exposure to the rain, snow, and low temperatures of their rearing areas. Only about 3 calves out of a possible 10 survive.
