Castor canadensis
Beaver (Castor canadensis)
Description: This is a very large brown rodent, with a flat tail, and large webbed feet. They chew trees down to build large dams and lodges and for food (bark). Beavers can change the environment by causing water to back up where it was not before or cut off water supplies all together. This can lead to the formation of a bog or fen and cause the downstream to slow or stop all together.
