Wild Mammals of North America. "Vancouver Island Marmot." In particular, forest clearcutting at low elevations[20] likely altered dispersal patterns. Vancouver Island Marmot Population and Habitat Viability Assessment Workshop (Jackson et al. Systematic marmot surveys have been conducted since 1979, with variable count effort and coverage of the Island. It is endemic to Canada - one of only a small handful of mammals to occur in this country and nowhere else. Family Sciuridae. [21] Major predators upon Vancouver Island marmots include golden eagles, cougars and wolves. 2015) Establishment of a non-profit registered charitable organization, the Marmot Recovery Foundation, both to raise funds and to administer the day-to-day recovery efforts (established 1998). World Book Encyclopedia. 2015). Thanks to recent recovery efforts, the population has increased from a low count in 2003 of less than 30 wild marmots living in a handful of colonies to just over 200 marmots on over more than 20 mountains in … A decline below that threshold precipates rapid decline. Dispersal involves traversing lowland conifer forests and valleys to other subalpine meadows. The Vancouver Island marmot population is still growing slowly and is extremely vulnerable to predation from wolves and cougars that can … It is the eleventh largest Island in Canada. Donate today to help the marmot recover. [2], Although endemic to Vancouver Island, Marmota vancouverensis now also resides successfully at several captive breeding centres across Canada as well as several sites on Vancouver Island at which local extinction was observed during the 1990s. Number of Cities: About fifty towns and cities are on Vancouver Island. Bryant (2005) reported the following: "Population counts began in 1979 and have continued, with variable coverage and intensity, until the present. Ecologist Justin Brashares suggests that at least some of the marmot's group behavior is learned, so that the loss of marmot "culture" has caused them to become more solitary, and interact aggressively rather than cooperatively when they do encounter each other.[23]. Vancouver Island Range. Size: Vancouver Island is about 460km long and 100km wide, with around 32,134km2 total area. 1 Vancouver Island marmot 2 Contents 3 [edit]Description 4 [edit]Life-history, habitat characteristics and population trends 5 [edit]Conservation status 6 [edit]Related species 7 [edit]Use as symbol The Vancouver Island marmot (Marmota vancouverensis) naturally occurs only in the high mountains of Vancouver Island, in British Columbia, Canada. The Vancouver Island marmot (Marmota vancouverensis) naturally occurs only in the high mountains of Vancouver Island, in the British Columbia.This particular marmot species is large compared to some other marmots, and most other rodents. The Vancouver Island Marmot is a remarkable animal. Wild population. or when marmots first arrived on the island. The Vancouver Island marmot population is still growing slowly and is extremely vulnerable to predation from wolves and cougars that can more easily access colonies along the logging roads puncturing high alpine forests. The Vancouver Island marmot (Marmota vancouverensis) is one of the rarest mammals in the world. Vancouver Island marmots have been documented to eat over 30 species of food plants, generally shifting from grasses in the early spring to plants such as lupines in late summer. Even with introductions into suitable habitats, only 30-35 individuals are present in the wild. [5][6] Due to the efforts of the recovery program, the marmot count in the wild increased from fewer than 30 wild marmots in 2003, to an estimated 250–300 in 2015. [27] In 1997 there were so few numbers of marmots on Vancouver Island that managers took the bold step of capturing some to create a "genetic lifeboat" and therefore create the possibility of restoring wild populations. [17] Suitable meadows are rare[18] compared to nearby regions of the British Columbian mainland or the Olympic peninsula of Washington State; habitat scarceness is believed to be the primary reason for the rarity of this marmot species. It is believed that populations expanded during the 1980s, Some natural meadows may be kept clear of invading trees by snow-creep and periodic avalanches or fire. The Vancouver Island marmot population will get a boost thanks to assistance from the Calgary Zoo. In 2009, Nagorsen and Cardini identified, from museum specimens, substantial physical differences between species that can only be explained by rapid evolution in a relatively isolated island context. Litter sizes average 3-4 pups, and weaned pups generally emerge above ground for the first time in early July. Vancouver Island lies in the temperate rainforest biome. In 1998 a new model for species recovery was born involving the government, private industry and public donors. Causes of marmot population declines are numerous. 100: 241–245.
