Habitat fragmentation is one of the leading causes of wildlife population decline. Wildlife corridors reconnect fragmented patches, allowing movement, gene flow, and welfare-positive range expansion.
Wildlife corridors address welfare at both individual and population levels. Individual animals attempting to cross roads face injury and death. Isolated populations in fragmented habitat suffer genetic inbreeding, reduced prey availability, and increased inbreeding-related health problems. Connectivity allows animals to move in response to seasonal, climatic, and resource changes — exercising their natural ranging behaviour rather than being confined to shrinking habitat patches. Infrastructure investment in wildlife crossings and landscape-scale corridor planning addresses individual welfare and population resilience simultaneously.
