Hedgehog Road Mortality and Wildlife Crossing Solutions

Hedgehog road mortality is a significant contributor to population decline. Engineering solutions and driver behaviour changes can reduce this preventable welfare and conservation problem.

Key Facts

An estimated 335,000 hedgehogs are killed on UK roads each year, representing approximately 25% of the total population
Hedgehogs are crepuscular and nocturnal, maximising their exposure during peak dawn and dusk commuter traffic
Roads fragment hedgehog habitat, isolating populations in areas that cannot support viable breeding groups
Wildlife crossing structures including tunnels under roads can restore connectivity for hedgehogs and other wildlife
Speed reductions in residential areas from 30mph to 20mph significantly reduce hedgehog road mortality
Hedgehog population decline is multi-causal but road mortality is consistently identified as a major contributing factor

Welfare Considerations

Road mortality kills hundreds of thousands of hedgehogs annually, each death preceded by the pain and distress of vehicle impact. Many hedgehogs do not die immediately but survive impact to die slowly at the roadside. At population level, this mortality rate contributes to the 50%+ decline in UK hedgehog populations since 2000. Infrastructure solutions that allow hedgehogs to cross roads safely address both the welfare of individual animals and the conservation of the population.

What You Can Do

Slow down particularly at dusk and dawn in residential areas where hedgehogs are active
Report road hedgehog casualties to the National Hedgehog Monitoring Programme for population data
Support local campaigns for 20mph speed limit reductions in residential areas
Advocate for wildlife crossing installation in new road schemes affecting hedgehog habitat
Create hedgehog highways (13cm gaps in garden fences) to reduce road crossing necessity
