The endangered Vancouver Island marmot remains one of the world's rarest mammals. 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. The first marmots went to Toronto Zoo in 1997, but this initial effort was quickly followed by efforts made by the Calgary Zoo and Mountainview Conservation and Breeding Centre in Langley, BC. The Marmot Recovery Foundation also built a dedicated marmot facility on Mt. Washington, Vancouver Island to further facilitate captive breeding and pre release conditioning. The fundamental idea was to produce marmots in a fashion that would facilitate their eventual return to the wild.
