Wildlife corridors connect fragmented habitats allowing animal movement essential for population welfare and genetic diversity. Supporting corridor creation and protection has wide-ranging welfare benefits.
Habitat fragmentation causes chronic welfare impacts at individual and population levels. Animals attempting to cross between habitat fragments face road mortality, hostile urban environments, and the energetic cost of navigation through unsuitable areas. Isolated populations gradually lose genetic diversity through inbreeding, increasing susceptibility to disease and reducing reproductive success. Corridors that allow safe movement between habitat patches enable natural population dynamics, reduce disease vulnerability through genetic mixing, and allow species to shift their ranges in response to climate change. Individual welfare improvements from corridors include reduced crossing mortality and access to more diverse food sources.
