Fencing is one of the most significant causes of habitat fragmentation.

Fence removal and modification are two of the Reserve's ongoing efforts to increase connectivity and ease the movement of animals like pronghorn and deer. In the Sun Prairie region, volunteers, staff, and local contractors will have helped remove nearly 70 miles of fence by the end of 2014.

Our fencing in Sun Prairie is also designed to secure the 31,000-acre range of APR’s bison herd by using a solar-powered electric wire configuration that also allows the passage of other large mammals.
