Photo by @chamiltonjames (Charlie Hamilton James) A beaver swims over to inspect its dam. Beavers are extraordinary engineers. They create dams to flood areas of forest so that the can access food safely. They can raise and lower the level of their ponds and they dig canals to transport food and building material.
