Wildlife corridors allow animals to move between fragmented habitat patches, reducing inbreeding, increasing foraging range, and improving population resilience.
Animals in fragmented habitats face welfare consequences from restricted movement including inability to find mates, food shortages when local resources are depleted, and increased risk of road mortality when crossing between patches. Corridors allow natural dispersal that reduces inbreeding and ensures genetic diversity. They also allow range shifts in response to climate change. Well-designed corridors include appropriate vegetation, crossing structures over roads, and connections between patches of sufficient quality habitat.
