Wildlife corridors connecting fragmented habitats reduce stress, injury, and mortality in wild animals by enabling safe movement, gene flow, and access to seasonal resources.
Wildlife corridors directly improve individual animal welfare by reducing the stress, injury, and mortality associated with navigating fragmented landscapes. Isolated populations experience higher rates of inbreeding, chronic stress from territorial conflicts in overcrowded patches, and nutritional deficits when unable to follow seasonal food sources. Roads represent a major welfare hazard — vehicle strikes cause painful deaths and injuries to millions of animals annually. By enabling safe movement, corridors reduce chronic stress, support population health, and allow animals to access the full range of resources their ecology requires. Corridor investment is thus both a conservation and an animal welfare intervention.
