Deer fencing along roads and in forestry affects welfare by preventing movement, causing entanglement injuries, and disrupting natural behaviour patterns, requiring design solutions that balance safety and connectivity.
Deer fencing creates a welfare trade-off between preventing road collision mortality and the welfare consequences of habitat fragmentation and entanglement. Poorly designed fencing that traps deer in enclosed areas causes starvation and chronic stress when resources are depleted. Entanglement in barbed wire or high-tension fencing causes severe injuries - particularly to fawns - that may result in prolonged suffering or death. Wildlife-friendly alternatives including jump posts that guide deer over fences, underpasses, and regular fence checking programmes reduce both collisions and entanglement mortality. Road planning that avoids creating deer movement bottlenecks reduces the need for extensive fencing.
