Wildlife corridors connect fragmented habitats enabling animal movement, gene flow, and population resilience. Effective corridor design is critical for species survival.
Wildlife corridors directly reduce individual animal suffering by enabling movement between habitat patches without crossing lethal barriers. Road mortality is one of the most significant and traumatic causes of wildlife death, with estimates of over 1 million vertebrates killed daily on roads in the US alone. Effective corridor design with crossing structures reduces this mortality while enabling the behavioral freedoms of movement, foraging, and social contact that define wild animal welfare. The welfare benefits extend beyond mortality reduction to include stress reduction from not being trapped in small, resource-limited patches.
