Species Profile
North American Beaver
Castor canadensis
A remarkable semi-aquatic mammal distinguished by its broad, flat tail, powerful orange incisors, waterproof fur, and exceptional ability to build dams and lodges.
North American Beavers are highly skilled builders that use branches, mud, and stones to construct dams and protective lodges. Their continuously growing incisors allow them to cut trees and gather woody vegetation for food and construction. They primarily consume bark, leaves, twigs, and aquatic plants. Beavers live in family groups consisting of a breeding pair and their offspring, cooperating to maintain their homes, defend territories, and store food for winter.
As ecosystem engineers, Beavers transform waterways into wetlands that provide habitat for fish, amphibians, birds, and numerous other species. Their dams can improve water retention, trap sediment, and create refuges during dry periods. However, flooding, tree damage, and blocked drainage systems sometimes bring them into conflict with property owners. Conservation and coexistence efforts emphasize protecting riparian habitats and using nonlethal water-management solutions where necessary.
Coexistence tip
Observe beavers from a safe distance, protect valuable trees with suitable fencing, and use nonlethal water-control methods to manage flooding.
Risk level
Low — Generally avoid humans but can inflict serious bites if cornered, threatened, or handled.
Why it matters
Beaver wetlands provide essential wildlife habitats.
Their dams improve water retention and ecosystem resilience.
