Wildlife corridors connect fragmented habitat patches, allowing animals to move between areas for foraging, reproduction, and seasonal migration. Connectivity reduces inbreeding, improves resilience, and decreases road mortality.
Animals in fragmented habitats face elevated mortality risk from road crossings, reduced prey availability, and stress from inability to complete natural behavioral needs. Inbreeding depression from small isolated populations reduces immune function and reproductive success, producing chronic welfare deficits across populations. Wildlife corridors address these harms at the landscape scale. Crossing structures benefit both common species and endangered ones, often with measurable reductions in road strike mortality and population genetic health improvements.
