The beaver can adapt to aquatic human environments easily and usually by choice. In aquatic human environments, beavers can adapt easily due to the abundance of food, shelter, and the lack of predators. Urban landscapes provide the ideal bark from trees, such as poplar, birch, cherry, pear, willow, maple, and pine trees that beavers will favor. Once a beaver has found a prevalent food source it will look for a den site that is relatively close to that food source. Beavers will typically start to knock down trees in September; they are gearing up for the winter to come.
After they chew down the tree, they will then either chew it up into smaller pieces or they will drag the whole tree into the water to add it to what’s called a “food bed” a food bed is a stash of food that a beaver will instinctively build under the waterline of its current waterhole. The beaver does this for one reason only, so the beaver will have access to food just in case the water freezes. Beavers are a rodent that is originally from the extreme northern section of the United States and Canada. It is in this area that this oversized rodent devolved the instinctual habits that it still carries on today, even in areas that do not get cold enough weather for the water to freeze. I have seen these beavers behave this way as far south as Florida. This is just what they do!
