Don't Leave It to Beavers

Beaver populations have increased significantly during the last half century and have spread across most areas of the country. As beaver populations expand, the problems created when they instinctively dam culverts become a concern for road engineers and maintenance crews. MTDC, with the assistance of U.S. Department of Agriculture Animal and Plant Health Inspection Service National Wildlife Research Center experts, published a report detailing methods to prevent beavers from plugging culverts.

Graphic image of the cover page for the report entitled: How To Keep Beavers From Plugging Culverts.Image of a culvert plugged by a beaver dam.The report, How to Keep Beavers from Plugging Culverts (0577–2830–MTDC), also discusses methods tried successfully and unsuccessfully by Forest Service personnel.
