Wild Animals

Road Ecology and Wildlife Welfare

Roads are among the most significant anthropogenic threats to wildlife, killing billions of animals annually and fragmenting populations across landscapes.

Key Facts

US roads kill an estimated 1-2 million vertebrates per day
Badger culls under road mortality alone kills more than 50,000 annually in the UK
Wildlife crossing structures reduce mortality by over 80% where implemented
Hedgehog numbers correlate inversely with road density across the UK
Reptile and amphibian populations are severely fragmented by roads in Europe

Welfare Considerations

Animals killed by vehicles typically suffer traumatic injury, and many are not killed immediately but die slowly from their injuries. Young animals dispersing from birth territories are disproportionately vulnerable. Road noise and light pollution cause chronic stress in animals living near roads, affecting behaviour, reproduction, and health over extended periods. The cumulative welfare impact of road networks is distributed across enormous numbers of individuals.

What You Can Do

Support wildlife crossing programmes on high-mortality road sections
Reduce speed on rural roads particularly during dawn and dusk movement periods
Report road casualties to national recording schemes
Advocate for wildlife-sensitive road planning and mitigation requirements
Join local wildlife road casualty recording initiatives
