Beavers can get a bad rap. Some people consider them pests because they dam up waterways and take up a lot of space. But beaver activity creates habitat for a diversity of plants and animals and helps improve water quality. So it’s worth it to work with beavers and coexist. Beaver are ecosystems engineers that have a positive ripple effect on our environment.

You Can Help

Be a flexible neighbor to beavers.

  • If beavers are chewing trees, wrap the trees with wire mesh fencing rather than relocating the beaver.
  • If a beaver dam on a stream or culvert is causing damaging flooding, protect the culvert with fencing or install a pond leveler.

More About Beavers

The beaver is a native species found across North America. They create ponds by felling trees to dam running water. After near complete local extinction (extirpation) in Virginia as a result of the North American fur trade, beaver populations have partially recovered.
