Wildlife Corridors and Road Ecology Welfare

Roads and transport infrastructure fragment wildlife habitat and cause billions of animal deaths annually worldwide, with wildlife corridors and crossing structures offering proven solutions to reduce mortality and maintain populations.

Key Facts

Roads are estimated to kill over one million vertebrate animals per hour globally across all species
Habitat fragmentation from roads reduces genetic diversity, blocks seasonal migration, and isolates populations
Wildlife crossing structures including tunnels, bridges, and culverts dramatically reduce animal mortality on roads
Badgers, hedgehogs, otters, amphibians, and deer are among the UK species most affected by road mortality
Light and noise pollution from roads disturb wildlife behavior far beyond the road surface itself

Welfare Considerations

Road mortality causes acute suffering and death for billions of animals annually, from instant death in high-speed collisions to prolonged suffering from non-fatal injuries. Animals that are injured but not killed face predation, starvation, and infection. Road fragmentation creates population isolation that leads to inbreeding depression and local extinction, representing a chronic welfare problem at the population level. Wildlife crossing structures have demonstrated dramatic reductions in mortality when properly located and maintained.

What You Can Do

Support campaigns for wildlife crossing structures on major roads in your region
Drive at appropriate speeds especially at dawn and dusk when wildlife is most active
Report road casualty wildlife to carcass recording databases that inform conservation planning
Advocate for wildlife-friendly road design standards in planning consultations
Support organizations like the Wildlife Trusts and Amphibian and Reptile Conservation that address road mortality
