Wildlife corridors - strips of habitat linking fragmented reserves - are essential for maintaining animal movement, gene flow, and access to resources, with direct welfare implications.
Wildlife corridors address welfare at both individual and population levels. For individual animals, connectivity means access to mates, food, and water without the high-risk crossing of roads or developed land. For populations, it prevents the inbreeding depression and local extinction that come from isolation. The welfare case for corridors is strong: animals trapped in isolated patches experience resource scarcity, inbreeding, and disease more acutely than those in connected landscapes. Investment in corridor creation - from garden hedgerow planting to major infrastructure projects - delivers wildlife welfare returns that compound over time.
