Beavers were brought back from the brink of extinction in the state when they were reintroduced in the Sandhills in the late 1930s. Today they have spread across the state and are thriving. They are also a good news/bad news proposition. What's good for the beaver isn't always good for people, like flooding land and destroying trees. On the other hand, their ponds provide waterfowl habitats and homes for other species.
