Effects of interstate highway fencing on white-tailed deer activity

Locations of white-tailed deer (Odocoileus virginianus) along a 41.4-km section of Interstate 84 (I-84) right-of-way in Pike County, Pennsylvania, were determined by radio telemetry and spotlight surveys. Bucks crossed roads more often (P 0.05) between road-kills and highway direction, habitat, topography, or fence placement. However, deer were killed more often ≤0.48 km of an interchange. Management efforts to reduce the incidence of road-killed deer should address increasing the effectiveness of deer fence and decreasing the incentive for deer to enter the right-of-way.
