The Vancouver Island marmot (Marmota vancouverensis) naturally occurs only in the high mountains of Vancouver Island, in British Columbia, Canada. This particular marmot species is large compared to some other marmots, and most other rodents. Marmots as a group are the largest members of the squirrel family, with weights of adults varying from 3 to 7 kg depending on age and time of year. 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. This is the result of an ongoing recovery program designed to prevent extinction and restore self-sustaining wild populations of this uniquely Canadian species.
This rare marmot is found only in the high mountainous regions of Vancouver Island, in British Columbia, the Canadian Species at Risk Act listing it as endangered in May 2000. In 1998, the population reached an all-time low of 75 individuals, a captive breeding programme being started during that time. In captivity, there are around 90 Vancouver Island marmots in four breeding facilities, while an estimated 30 members of this species live in the wild ibn 2004. The ultimate goal is to restore a sustainable population of 400-600 Vancouver Island marmots in the wild, so there’s still much to be done. 2005 was a successful year, with 150 individuals in captivity and over 44 pups born.
