Beavers are best known for their natural trait of building dams in rivers and streams, and building their homes (known as beaver lodges) in the resulting pond. Beaver sign is usually quite obvious as they cause tremendous changes in their environments, from building ponds and lodges, to cutting down even very large trees, to storing young branches in the mud. In the image shown here, beavers have worn a trail through the brush.
