Detailed explanation-1: -They are able to stay underwater for longer periods of time. They have large, ever-growing, chisel shaped teeth. Gives them access to food that they couldn’t reach without felling the tree like buds, leaves and bark of trees. Also provides them with woody branches to use in making their dam and lodge.
Detailed explanation-2: -Why do beavers build dams? Beavers build dams across streams to create a pond where they can build a “beaver lodge” to live in. These ponds provide protection from predators like wolves, coyotes, or mountain lions.
Detailed explanation-3: -Beavers increase biodiversity and provide salmon habitat They bring wood into the water, and that wood provides food and shelter for insects, and those insects become food for other species, including salmon.
Detailed explanation-4: -Lodges are dome-shaped structures built of sticks and mud with a large interior chamber above the water line. Lodges vary in size from 6 to 40 feet, depending on the number of beavers in the colony. Beavers sometimes dig burrows into the banks of ponds, rivers and drainage ditches instead of building a lodge.
