, with small ears and large hindfeet. In summer, dorsal pelage is brownish, dusky gray, or even rusty; ventral pelage, under chin, and sometime feet are white. Most populations have a white fur in winter, although underfur remains gray, and white is restricted to hair tips. Some populations along the Pacific coast of North America are polymorphic because part of the population remains brownish in winter. Autumn molt occurs in August—=November, and spring molt occurs in March—June.

Various forest types of conifers, aspen, birch, beech, maple, and mixed hardwoods. The Snowshoe Hare prefers subclimax forest, transition zones, and swamp edges. Its populations reach peak numbers after fire when shrub and regrowth cover becomes dense, and lowest densities occur when forests mature and ground cover becomes sparse. The Snowshoe Hare favors edge habitat but avoids open habitat. It is not found as a relict species in small isolated patches of forest. A study showed that Snowshoe Hares use multiple vegetation types even when food and cover are apparently abundant in a single habitat.

The Snowshoe Hare eats grasses, sedges, dandelions, ferns, and different herbs in summer. Its winter diet includes birch, spruce, willow, tamarack, and pine. Regular runways are used to reach favored feeding areas.

. Onset of breeding was early in years with high spring temperatures and fewer days of snow cover. The Snowshoe Hare is promiscuous. Gestation is ¢.36 days. Two litters per year are typical in northern parts ofits distribution and at high elevations; 3—4 litters/year are typical in central parts of its distribution. Litter size increases by c.1 young from the first litter of the season to later litters, and regionally from c.2-2 young to c.6 young. Females have 7-5-17-9 young/year. Young start hopping at c.2 days old and dig at c.5 days old. Young gather at nursing places 1-2 hours after sunset and are nursed for 2-5 minutes immediately after females arrive. Young begin to eat solid food at 6-8 days old.

Home range sizes of Snowshoe Hares are 5-9-13 ha in thick cover. Females have smaller home ranges than males, and adults have larger home ranges thanjuveniles. In the northern part of the distribution, populations cycle every 8-11 years, with peak densities up to 300 times higher than during the lowest phases but normal ranges are 10-30 times higher. Population cycles are synchronous over wide geographical areas. Causes that trigger population crashes are food scarcity due to the high densities during population peaks and predators, or only effects of predation pressure such as the Canadian Lynx (Lynx canadensis) wellknown case. Southern populations of Snowshoe Hares appear to be non-cyclic, or they fluctuate with reduced amplitude. The Snowshoe Hare has a clear dominance hierarchy. Males are more frequently involved in more intense interactions than females. Males are more dominant during winter, and females are more dominant during the breeding season in summer.

Classified as Least Concern on The [UCN Red List. The Snowshoe Hare is widespread, and its populations are stable. The population in Canada and Alaska is continuous, but they are fragmented further south in the contiguous USA. Some concern exists about status of populations in the south-eastern USA where the distributional limit might be receding northward due to habitat loss, fragmentation, increase in predator numbers, and perhaps climate change and resulting loss of snow cover. Status of distinct populations along the Pacific coast of North America is unclear. The Snowshoe Hare is an important game animal and a forestry pest. The Snowshoe Hare in New Mexico (USA) is in need of enhanced management and conservation attention due to restricted distribution and low densities.
