In 2013, the West Fork Fire Complex burned almost 80,000 acres at high elevation and killed huge areas of smaller trees and subalpine fir. When you see one, we hope you’ll recall some of these interesting facts about snowshoe hares. ), and ascarids (Ascaris sp.). 01 : 30 MIN SEC. Snowshoe hares that camouflage themselves by changing their coats from brown in summer to white in winter face serious threats from climate change, and it’s uncertain whether hare populations will be able to adapt in time, according to a North Carolina State University study. It normally lives 3 years in the wild. Snowshoe hare populations rise and fall on a regular 10-year cycle, and when they crash, “life becomes hell for the lynx,” says Stan Boutin, a biologist at the University of Alberta who … Aside from hunting, greatest threats for the survival of hares in the wild are habitat loss and lack of food. Status, Trends, and Threats Status NatureServe: G5 IUCN: LC (Least Concern) Trends Populations of snowshoe hare are subject to cycles of high abundance and scarcity. While snowshoe hares are not considered threatened or endangered, the likely population decline – as suggested by a Michigan State University study, … Snowshoe hares face a new threat: warmer winters By Samantha Harrington | Jan 9, 2018 In the absence of snow, white fur is a liability. Within the United States, most of these coniferous forests are found on mountaintops, such as the Rockies, or near the Canadian border.
During the summer in Wisconsin, a snowshoe hare is an unremarkable shade of brown. It’s always fun to spot a snowshoe hare in its natural environment. Snowshoe hare recognition of coat color mismatch could be vital to their survival in an environment that is projected to change. Originally, we planned on approaching each hare with a dog but soon realized that hare behavior was influenced by the noise created by the observer while locating the hare. Predators include bobcat, gray fox, red fox, red-tailed hawk, great horned owl, and barred owls. Understory removal may impact the capability of forests to support snowshoe hares, the primary prey of lynx. Like other hares it reingests its fecal pellets (coprophagy). Then things got worse. By Samantha Harrington | Tuesday, January 9, 2018.
), roundworms (Trichostrongylus sp. In the Allegheny Mountains, the species is found on steep, heavily forested slopes of hemlock, rhododendron, and mountain laurel with a dense, brushy understory (Merritt 1987). Snowshoe Hares in Northern Boreal Forests Karen E. Hodges, Centre for Biodiversity Research, University of British Columbia, 6270 University Boulevard, Vancouver, BC V6T 1Z4, Canada Abstract—Snowshoe hares exhibit eight to 11 year population fluctuations across boreal North America, typically with an amplitude of 10 to 25 fold. Snowshoe hares live in the coniferous and boreal forests of the Rocky Mountains, the Appalachian Mountains, the Pacific Northwest, New England, Alaska, Minnesota, Michigan, and Montana. This has an effect on its predators too. The biggest threat to snowshoe hares is climate change. The beetles left only small trees and subalpine fir in their wake, raising concern that reduction in the overstory might affect the habitat of snowshoe hare and secondary prey species. The number of snowshoe hare harvested dropped rather steadily from a peak of nearly 800,000 in the mid-1970s to fewer than 50,000 in 2009, according to … Such threats include certain kinds of forest management and fire suppression efforts that reduce the amount of understory vegetation in forests that support lynx. Current Threats: Click here to watch video from the field. Part 1: Background: Canadian Lynx and Snowshoe Hares In the module on Limited Population Growth, we studied the dynamics of a single population, taking into consideration only its "natural" growth rate and the "carrying capacity" of its environment.Mathematical ecology requires the study of populations that interact, thereby affecting each other's growth rates. Distribution
Populations ebb and flow roughly ever decade due to disease. mountain laurel and rhododendron. Another threat is the continued loss of habitat and second growth forests are lost due to the absence of timber harvesting. In the Poconos, the snowshoe hare favors mature forests with swamps and bogs at high elevations. The population in an area will build up over a period of years to peak abundance, followed by a sudden decline to a very low level. Snowshoe hares feed at night, following well worn forest paths to feed on trees and shrubs, grasses, and plants.
