Wild UK Amphibian Road Mitigation

Infrastructure solutions for reducing amphibian road mortality, including tunnels, drift fences, and patrol programs.

Key Facts

Amphibian tunnels with drift fencing have reduced road mortality by 90% at some crossing sites
Tunnels must be of adequate dimensions and correctly positioned to be effective
Councils and Highways England are increasingly incorporating amphibian tunnels in road projects
Volunteer patrol programs have saved millions of toads at high-mortality road crossings
Warm, wet nights in February-March trigger the main migration in the UK

Welfare Considerations

Road mortality causes direct, traumatic death for individual amphibians at scale. Infrastructure solutions that allow safe passage under roads eliminate this mortality source for all future migrations. The welfare benefit of a correctly installed tunnel compounds over decades of use.

What You Can Do

Advocate for amphibian tunnels at known high-mortality road crossing sites
Volunteer with or donate to local toad patrol groups during migration season
Report amphibian road casualties to inform conservation planning for future infrastructure
