The Completed Beaver Deceiver
Because small beavers might fit through the metal railing that was along the trash rack, additional fencing material was added along the length of the railing. Most installations will probably need some additional measure like this to prevent beavers from getting branches and other material around the landward side of the fence and into the culvert or other structure being protected. In addition, steel wire was stapled to the corner posts and the braces to prevent beavers from chewing through them in the unlikely event that one should get inside the structure.
