Hedgehog Road Mortality and Mitigation

Road casualties are a major cause of hedgehog mortality in the UK, with simple infrastructure changes offering significant welfare and conservation benefits.

Key Facts

Road kills are estimated to account for hundreds of thousands of hedgehog deaths annually in the UK
Hedgehogs are most active at night when road visibility is lowest
They have a defensive response of curling into a ball rather than fleeing vehicles
Female hedgehogs with young are particularly vulnerable as they range further to find food
Speed reduction schemes and road underpasses have been shown to reduce hedgehog road mortality
Hedgehog tunnels under roads are effective where installed alongside fencing that guides animals toward crossings

Welfare Considerations

Road mortality represents one of the most significant welfare problems facing hedgehogs in the UK. The defensive curl response that protects hedgehogs against predators is entirely ineffective against vehicles and may contribute to their death by preventing escape. Death from vehicle impact varies from instantaneous to prolonged suffering from injuries. Simple, low-cost interventions - reducing speed limits on rural roads at night, installing drift fencing guiding animals to underpasses, and raising awareness among drivers - can significantly reduce casualties. Reporting road-killed hedgehogs to the PTES roadkill survey contributes to mapping and mitigation planning.
