We evaluated the efficacy of several fencing designs for restricting movements of 18 captive, female white-tailed deer (Odocoelus virginianus), including standard wovenwire fencing (1.2-m, 1.5-m, 1.8-m, 2.1-m, and 2.4-m tall), opaque fencing (1.2-m, 1.5-m, and 1.8-m tall), and an outrigger fence (i.e., 0.6-m outriggers attached to a 1.2-m-tall wire fence angled at 45º). We recorded the number of successful fence crossings for each deer and characterized behaviors associated with each failed crossing attempt. No deer crossed the 2.4-m fence, whereas all deer crossed the 1.2-m fence. We observed no differences in crossing success between woven-wire and opaque fencing at heights <1.8 m. The outrigger fence was a effective as the 2.1-m fence when the outrigger was angled toward the deer. Efficacy decreased when the outrigger was angled away from the deer. Therefore, this fencing design may act as a 1-way barrier, discouraging deer from entering the roadway, but, unlike standard 2.4-m fencing, allowing them to exit it should they become trapped.
