Wild Mammal Road Casualties and Mitigation

Road traffic kills millions of wild mammals annually in the UK, making roads one of the most significant welfare threats to wildlife.

Key Facts

An estimated 100,000 hedgehogs, 50,000 foxes, and 100,000 badgers are killed on UK roads annually
Badgers are particularly vulnerable due to foraging patterns that repeatedly cross roads
Wildlife underpasses and badger gates under roads significantly reduce casualty rates
Seasonal peaks in wildlife casualties correspond to dispersal, mating, and migration periods
Citizen science road casualty recording provides data for infrastructure planning

Welfare Considerations

Road traffic kills cause acute welfare harm to individual animals and population-level harm to sensitive species. Badgers killed on roads may leave dependent cubs in setts. Hedgehog casualties disproportionately affect females moving between territories. Deaths are often not instantaneous — injured animals die over hours or days from the roadside. Infrastructure solutions including wildlife underpasses, road crossing gantries, and vegetation management have demonstrated significant casualty reductions where implemented.

What You Can Do

Drive carefully at dawn, dusk, and night when wildlife movement peaks
Report road casualty sightings to citizen science recording schemes
Advocate for wildlife crossing infrastructure in road construction and renovation
Support local wildlife groups monitoring road casualty hotspots
Move injured animals from the road if safe to do so and contact wildlife hospitals
