Wildlife corridors link fragmented habitat patches, enabling movement, gene flow, and population viability. They also directly reduce welfare harms caused by isolation and habitat loss.
Wildlife corridors reduce welfare harms in multiple ways. By enabling movement between habitat patches, they reduce the risk of starvation in resource-poor fragments. By allowing genetic mixing, they reduce inbreeding depression and associated disease vulnerability. By providing safe movement routes, well-designed corridors reduce roadkill mortality — a source of acute trauma for millions of animals annually. Corridor protection and creation is a high-impact welfare intervention that operates at landscape scale, benefiting entire populations rather than individual animals.
