In Canada and probably elsewhere,  such structures are also used to control the flow of water in culverts and avoid beavers to obstruct the culvert with dams, flooding, eroding the roads or various other structures in the area.See   http://www.nature-track.com/Living_With_Beavers.html 

But I would difficult to make the inventory of such structures in forestry areas.
