NORTH AMERICAN BEAVER (Castor canadensis): SPECIES ACCOUNT

Beavers are found in North America, northern Europe, and northern Asia. After a decrease in population, these animals have been reintroduced to Russia, Scandinavia, and Argentina. They are also found in Chile.

Beavers live primarily along streams, ponds, lakes, swamps and other waterways, in areas where they can build dams. They are found mainly in areas with a year-round water flow, but are found occasionally in roadside ditches, drainage ditches, and sewage ponds. They are have also become more common in urban areas.

Beavers feed primarily on the bark and outer layers of deciduous trees such as birch, willow, alder, sweet gum, magnolia, maple, and dogwood. They eat twigs, leaves, and roots of trees and shrubs. They also eat various parts of aquatic plants, especially the young shoots of water lilies. During the warmer months, they may add grasses, corn, and other plants to their diet.

Populations of beavers, once extremely low, are gaining in numbers. The Eurasian beaver is listed as Near Threatened, not currently threatened, but could become so, by the World Conservation Union (IUCN).
