Ecology and Life History
Short General Description
A hoofed mammal (caribou).
Migration
false - true - false - Makes seasonal elevational migrations; early winter habitat lower in elevation than late winter habitat (Rominger and Oldemeyer 1989).
Non-migrant
false
Locally Migrant
true
Food Comments
In many areas, relies heavily on lichens. In southern Selkirk Mountains of British Columbia, shifted from diet of primarily vascular taxa during snow-free months to an arboreal lichen-conifer diet during late winter; in winters with slower snow accumulation, foraged extensively on myrtle boxwood (PACHISTIMA) and other vascular plants (Rominger and Oldemeyer 1990). Late fall and early winter diet consists of low evergreen shrubs, mushrooms, grasses, and sedges (Matthews and Moseley 1990).
Reproduction Comments
Mating occurs primarily in last half of October. Male defends group of several females. Calving occurs in late May or early June, though the timing of the rut and calving varies somewhat among different herds. Females begin breeding at 2-3 years. Most adult females bear a calf each year. End of metabolic weaning occurs at about 6 weeks, though nursing may continue for at least 160 days (Can. J. Zool. 70:1753).
Ecology Comments
Tends to congregate in family groups of 3-10; adult males solitary except in breeding season (Matthews and Moseley 1990). Annual calf mortality, due to predation, severe weather, or malnutrition, 40-70% (Matthews and Moseley 1990).

Global Range
FG - 20,000-2,500,000 square km (about 8000-1,000,000 square miles) - FG - Historic range: southeastern Alaska and much of Canada, and south into northern U.S. from New England to Washington. Deforestation eliminated caribou from New England and adjacent Canada, the Great Lakes states, and North Dakota by the early 1900s. Still widespread across much of boreal forest in Canada (Kelsall, 1984 COSEWIC report). A remnant U.S. population survived in the Cabinet and Yaak Mountains of Idaho and Montana until the 1950s. A once-extensive population in the Selkirk Mountains of eastern Washington, northern Idaho, and southeastern British Columbia) still survives in small numbers. Reintroductions have been attempted in Maine.
