North American beaver (Castor canadensis), one of two species of beaver that build dams. Beaver dams are dams built by beavers to provide ponds as protection against predators such as coyotes, wolves, and bears, and to provide easy access to food during winter.These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species.rees approaching a diameter of 90 cm may be used to construct a dam, although the average is 10 to 30 cm. The length depends on the diameter of the tree and the size of the beaver. There are recorded cases of beavers felling logs of as much 45 m tall and 115 cm in diameter.
