The Vancouver Island marmot (Marmota vancouverensis) naturally occurs only in the high mountains of Vancouver Island, in British Columbia.[3][4] This particular marmot species is large compared to some other marmots, and most other rodents. Marmots are the largest members of the Sciuridae family, with weights of adults varying from 3 to 7 kg depending on age and time of year.[5]
Marmota vancouverensis is one of only five land mammals endemic to Canada.[6] 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.[7][8][9] There was an 80% to 90% loss in population, starting around the 1980s and lasting until the early 2000s.[10] The population has since started to regain its ranks. This is the result of an ongoing recovery program designed to prevent extinction and restore self-sustaining wild populations of this unique Canadian species.[11][12] 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.[13] As of the fall of 2021, there were approximately 25 colonies with marmots likely to emerge.[14] These are spread between 2 metapopulations (clusters of colonies that marmots could travel between), and one isolated colony at Steamboat Mountain.[4] There may be marmots in the Schoen Lake area, but there has not been a confirmed sighting in that area for over 5 years.[4]
