Wildlife Corridors and Animal Welfare

Wildlife corridors connect fragmented habitats, allowing animals to move safely between areas. They reduce vehicle collisions, increase genetic diversity, and dramatically improve wild animal welfare outcomes.

Key Facts

Habitat fragmentation is one of the leading drivers of wildlife population decline globally.
Wildlife corridors are strips of connected habitat linking isolated patches and allowing safe animal movement.
Road crossings (underpasses and overpasses) are the most effective corridors in urbanized landscapes.
Wildlife crossing use has been documented for large mammals, small mammals, reptiles, and amphibians.
The Banff wildlife overpasses in Canada reduced wildlife-vehicle collisions by 80% in target areas.
Corridors also facilitate gene flow between populations, reducing inbreeding and genetic vulnerability.

Welfare Considerations

Wildlife corridors address one of the most pervasive sources of wild animal welfare harm: road mortality and the isolation stress of fragmented populations. Animals forced to cross roads face death or injury; populations trapped in isolated habitat patches face resource competition, disease spread, and genetic deterioration. Corridors are the infrastructure solution that reduces these harms at landscape scale. While not cheap to construct, wildlife crossings deliver measurable welfare and conservation benefits that compound over time. Investment in corridor infrastructure is one of the most cost-effective conservation and welfare interventions available in developed landscapes.

What You Can Do

Support wildlife corridor advocacy organizations in your region.
Advocate for wildlife crossing infrastructure investment in road construction and maintenance budgets.
Learn about local wildlife movement patterns to inform corridor siting advocacy.
Donate to organizations that fund wildlife crossing research and implementation.
Support land conservation efforts that preserve natural corridor functions between protected areas.
