The Vancouver Island marmot (Marmota vancouverensis) naturally occurs only in the high mountains of Vancouver Island, in British Columbia. 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.[3][4] This is the result of an ongoing recovery program designed to prevent extinction and restore self-sustaining wild populations of this unique Canadian species.[5][6] Due to the efforts of the recovery program, the marmot count in the wild increased from less than 30 wild marmots in 2003, to an estimated 250-300 in 2015.
