[2] The black-capped marmot lives in arctic tundra and alpine habitats from near sea-level to an altitude of 2,000 m (6,600 ft).

[2] It is a relatively small marmot (head-and-body length c. 39.5–61.5 cm or 15.6–24.2 in, weight 1.65–5.4 kg or 3.6–11.9 lb) with a short tail.

They live in colonies formed from many separate burrows, each occupied by an adult pair and their offspring.

The solar altitude plays a significant role in the daily activity pattern of family groups of black-capped marmots.

[5] It also alters the soil properties that affect the floral structure and distribution of the Arctic tundra by burrowing, hibernation, trampling and reproduction.
