Habitat

Mountain beavers primarily inhabit moist, coniferous forests in the Pacific Northwest of North America, from California to British Columbia. They prefer areas with dense undergrowth, such as near streams or in damp, shaded slopes, where they can dig burrows. These habitats offer ample vegetation for food and protection from predators.

Diet

Mountain beavers are herbivores that primarily eat ferns, leaves, buds, and bark from a variety of plants. They forage at night or during dawn and dusk, often clipping and storing vegetation in their burrows for later consumption. Their feeding behavior includes selective browsing on understory plants in moist environments.

Behavior

Mountain beavers are solitary animals that live in elaborate burrow systems, often with multiple entrances for escape. They are primarily nocturnal or crepuscular, emerging to forage and gather food while avoiding daytime heat. They exhibit territorial behavior, defending their burrows with scent markings and vocalizations.

Conservation Status

The mountain beaver is classified as Least Concern by the IUCN, with stable populations in most areas. Major threats include habitat loss from logging and urban development, which fragment their forested habitats.
