Wildlife corridors that connect fragmented habitats enable animal movement essential for genetic diversity, foraging, and welfare across landscapes increasingly divided by human infrastructure.
Wildlife corridors address welfare at a landscape scale by enabling animals to move between habitat patches to find food, mates, and shelter. Fragmented populations that cannot move face increased competition for resources, higher predation risk from concentration, and reduced genetic diversity that compromises resilience to disease and environmental change. Road kills represent a massive and often underestimated welfare burden. Infrastructure solutions including wildlife bridges, underpasses, and habitat stepping stones have demonstrated effectiveness for many species. Urban wildlife corridors including connected gardens, parks, and verges play an underappreciated role in urban biodiversity welfare.
