North American Beaver - July evening, Central Michigan
The beaver is not your typical rodent. It’s the largest one on the continent, and the only one that can cut down mature trees
Beavers can drastically alter landscapes. Working in family groups of four to eight, a beaver colony can cut down more than a ton of trees per year. This colony has dammed a stream with logs, mud and stones to make a pond. The land is so newly flooded that some trees have not yet drowned.
By altering streams, beavers expand wetlands , offering rich habitat for other species. Beaver ponds can also control runoff and reduce erosion. Eventually, this pond will clog with sediment. At that point, or when all accessible trees are cut, the colony will abandon its effort and begin again elsewhere.
This diorama is located in the Bernard Family Hall of North American Mammals.
For your nightmares tonight:
The largest rodent on the continent
Can cut down mature trees
Semiaquatic with closeable ears and nostrils and webbed hind feet
Their thick, paddlelike tails are covered with scaly-patterned grooves for flexibility.
