Signs of Active Beavers
If beavers have bank dens on rivers that remain open all winter, they are not subjected to the confines of a dark, damp lodge for several months. They have access to fresh food year round, and aren’t limited to the pile of aging branches under the ice that they stored last fall near their lodge. On the other hand, beavers that do live in ponds that freeze over often can find an opening in the ice if there’s a big enough January or February thaw. In either case, signs of their activity on land can be found.
