State Rank Reason (see State Rank above)
Species is common in montane environments and can be quite abundant at times. Increased variability of snow presence and loss of snow pack and decoupling of molting periods with snow presence may lead to declines in populations of this species through increased predation rates.

How we calculate Conservation Status Ranks
 
General Description
This large lagomorph is characterized by large feet and ears. Its pelage is brown for most of the year, but becomes white in the winter. Its large hind feet allow it to move easily over the snow. This species is an important prey item form mid to large sized forest carnivores. Although its range extends into the river bottoms and draws of eastern Montana, it is most frequently observed in the montane forests within the western and central regions of the state.

Diagnostic Characteristics
Snowshoe Hares can be separated from cotton-tail rabbits by size and general morphology, and from jackrabbits by the white outer margin of the ear which is present year round but more distinct in summer.

Migration
Non-migratory.

Habitat
In western MT, apparently preferred fairly dense stands of young pole-sized timber with some use of more open stands, openings, and edges (Adams 1959, Koehler et al. 1979). Uses dense riparian thickets in eastern Montana (Hoffmann et al. 1969).

National Vegetation Classification System Groups Associated with this Species

Food Habits
Spring and summer: forbs and grasses. Fall and winter: more shrubs and sometimes conifer needles. Occasionally reingests feces. Sometimes eats sand (Adams 1959).

Ecology
Home ranges may overlap (Adams 1959).

Reproductive Characteristics
Breeding season late February to early July. First pregnancy noticeable in late March. Lactation from late April to late September. 2.8 to 2.9 litters/year. 2.6 to 3.0 young/litter (Adams 1959).
