Testing Wildlife Friendly Fencing Modifications to Manage Wildlife and Livestock Movements

Fences along roadways serve as safety measures to protect humans from vehicular collisions with wildlife and livestock by containing animals in appropriate pastures and keeping them off roadways. Fences can act as semi-permeable or complete barriers to wildlife movement. As a consequence, through landscape fragmentation, fences reduce landscape connectivity, impede resource selection, and are a direct cause of mortality in ungulates (e.g., pronghorn, elk, deer) and other species (e.g., greater sage-grouse). To combat these effects on wildlife, multiple fence modifications have been recommended by management agencies using the best available science to either facilitate or deter wildlife and/or livestock from crossing fences.
