Wildlife corridors allow animals to move between fragmented habitats, reducing the welfare consequences of isolation, inbreeding, and inability to access adequate food and mates.
Fragmentation traps animals in habitats that cannot fully meet their needs, creating chronic stress from food insecurity, limited mate choice, and inability to move away from threats. The individuals experiencing these consequences — the pronghorn that cannot reach winter range, the mountain lion inbreeding through genetic isolation — are the welfare reality of disconnected landscapes. Wildlife corridors address animal welfare at population scale, restoring the movement freedom that allows wild animals to meet their needs and avoid the stress of constrained, impoverished environments.
