The only species of marmot endemic to Vancouver Island, [11] it apparently evolved rapidly since the retreat of the Cordilleran ice sheet some 10,000 years ago. [12] It is distinct from other marmot species in terms of morphology, [13] genetics, [14] behaviour, [15] and ecology. [16]
Grey wolves follow the ungulates. Bears, such as black and grizzly, enjoy the many berries of the alpine meadows in the zone. Smaller mammals like the wolverine, hoary marmot, the endangered Vancouver Island marmot, Arctic ground squirrel, and the Siberian lemming are present. Birds of prey include the golden eagle and gyrfalcon.
Marmots are large rodents with characteristically short but robust legs, enlarged claws which are well adapted to digging, stout bodies, and large heads and incisors to quickly process a variety of vegetation. While most species are various forms of earthen-hued brown, marmots vary in fur coloration based roughly on their surroundings.
Found in the wild only on Vancouver Island in British Columbia, the marmot differs significantly from other marmot species. [3] In an effort to increase Vancouver Island marmot populations, the Vancouver Island Marmot Recovery Foundation has established captive breeding facilities across Canada. [ 4 ]
Ground squirrels are rodents of the squirrel family that generally live on the ground or in burrows, rather than in trees like the tree squirrels.The term is most often used for the medium-sized ground squirrels, as the larger ones are more commonly known as marmots (genus Marmota) or prairie dogs, while the smaller and less bushy-tailed ground squirrels tend to be known as chipmunks (genus ...
The National Park Service wants to replant sequoia groves in Sequoia and Kings Canyon National Parks, where wildfires in 2020 and 2021 inflicted lasting damage on the iconic sequoia forests.

Habitat size and numbers of species are systematically related. Physically larger species and those living at lower latitudes or in forests or oceans are more sensitive to reduction in habitat area. [23] Conversion to "trivial" standardized ecosystems (e.g., monoculture following deforestation) effectively destroys habitat for the more diverse ...
