Wildlife corridors connect fragmented habitats and allow animals to move safely between areas, reducing road mortality, inbreeding, and resource stress.
Wildlife corridors address a welfare problem at its structural root: the fragmentation of habitats by roads, agriculture, and development that forces animals to either remain in isolated and resource-limited areas or attempt dangerous crossings. Animals trapped in isolated populations face increasing resource competition, inbreeding, and higher stress, while those attempting to cross roads face direct mortality. Corridors reduce these welfare harms by allowing natural movement, foraging range expansion, and social contact with individuals from other populations. At the garden scale, small but meaningful contributions to urban wildlife corridor connectivity are possible through removing or adding gaps to fences, creating pond networks, and planting wildlife-friendly vegetation that connects adjacent green spaces.
