Wildlife corridors connect fragmented habitats, allowing movement, genetic exchange, and seasonal migration — reducing isolation-related welfare and population harms.
Habitat fragmentation harms wildlife welfare directly by preventing movement between food patches and water sources, isolating social groups, and forcing animals into human-dominated landscapes where they face vehicle strikes and conflict. Wildlife corridors address these welfare harms alongside their conservation benefits. The design of effective corridors is species-specific — predators require different crossing dimensions than ungulates, and aquatic corridors serving fish differ from terrestrial ones. The human health and safety benefits of reducing wildlife-vehicle collisions also align with animal welfare in making the case for corridor investment.
