The burrows they create and vacate become homes for other wildlife such as rabbits, skunks, opossums, raccoons, and foxes. In moderate numbers, groundhogs prove to be very valuable. Responding to their natural instinct to stop the flow of running water, Beavers build dams with the materials available to them which usually consists of small trees of two to six inches in diameter, but could be as large as 33 inches thick.
