host several species (Hall, 1981). Habitat varies throughout the region. Maine, New Hampshire, and Vermont, in the north of the region, have a humid continental short summer climate, with cooler summers and long, cold winters. Massachusetts, Connecticut, and Rhode Island, in the south, have a humid continental long summer climate, with hot summers and cold winters. The average rainfall for most of the region is from 1,000 to 1,500 mm (40 to 60 in) a year, although the northern parts of Vermont and Maine see slightly less, from 500 to 1,000 mm (20 to 40 in). Snowfall can often exceed 2,500 mm (100 in) annually (New England Climate Initiative, 2006). Most mammals in this region exhibit specializations for dealing with the sometimes harsh winter conditions. A comprehensive listing of all species found in the region follows.
