Vancouver Island Marmot (Marmota vancouverensis)

The Vancouver Island marmot is Canada’s most endangered endemic mammal and one of the rarest mammals in the world. Although conservation breeding and reintroduction programs have given this species a fighting chance, it continues to teeter on the brink of extinction.

Roughly the size of a house cat, these members of the rodent family are extremely sociable, often seen greeting one another with nose-touching and play fighting. When in danger, the Vancouver Island marmot makes a piercing whistle sound, earning it the nickname “whistle pig.” These animals build burrows for giving birth, hiding from danger and hibernating from early October to late April. When spring arrives, they often have to tunnel through several metres of snow that have covered their dens.

Habitat

Vancouver Island marmots live in subalpine meadows. For an area to offer suitable habitat, it needs to have a soil structure suitable for constructing burrows and enough grass and other vegetation for food. Vancouver Island marmots also use habitats created by clear-cut logging.

Range

As its name suggest, this species occurs only on Vancouver Island, British Columbia. They were once found in many parts of the island but have disappeared from about two-thirds of their historic natural range. Today they are limited to sites on Mt. Washington and the Nanaimo Lakes region. Populations plummeted in the 1990s, and by 2003, fewer than 30 wild marmots were recorded.

Threats

Vancouver Island marmots have taken to colonizing clear-cut forests. While these habitats work well in the short term, they become unsuitable for marmots as the logged forests start to grow back. Furthermore, females produce significantly fewer offspring in these areas. Predators like cougars, wolves and golden eagles are major threats — threats that may increase if warmer temperatures caused by climate change reduce the amount of time that marmots spend hibernating in safety.

Recovery

Recommended Recovery Actions

B.C.’s Recovery Strategy for Vancouver Island marmots calls for ongoing conservation breeding and release to increase marmot numbers and maintain genetic variability. It also recommends using releases and translocations to maximize breeding opportunities for wild marmots.
