Quick answer
North American Beavers feed on bark, twigs, aquatic plants, and roots, adjusting with season, age, and what is abundant in Rivers, lakes, and ponds across North America. That label is a preferred pattern, not every item an individual might sample.

North American Beaver diet overview
North American Beavers (Castor canadensis) are best summarised as Herbivore — bark, twigs, aquatic plants, and roots. Anatomy and habitat (Rivers, lakes, and ponds across North America) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How north american beavers find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
North American Beaver role in the food web
As herbivores shaping plants and seeds, north american beavers move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild north american beavers. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Dam building
Beavers cut trees with powerful incisors and weave branches into dams that raise water levels, protecting lodge entrances and creating ponds. These wetlands filter water, reduce flooding downstream, and provide habitat for hundreds of species — beavers are considered ecosystem engineers.
Lodges and family life
Beaver families live in dome-shaped lodges with underwater entrances. Kits are born in spring and stay with parents for up to two years, helping maintain dams and learn construction skills. Castoreum from scent glands marks territory.
