Hedgehog Road Mortality: Scale, Impact and Solutions

Road traffic kills an estimated 100,000 hedgehogs annually in Britain, contributing to dramatic population decline.

Key Facts

Between 100,000 and 335,000 hedgehogs are killed on British roads annually
Roads create barriers to movement fragmenting hedgehog populations
Male hedgehogs travel up to 3 kilometres per night making them especially vulnerable
Underpasses at known hedgehog crossing points reduce road mortality
Hedgehog populations have declined by 30% in urban areas since 2000

Welfare Considerations

Road mortality causes acute suffering in individual hedgehogs and chronic population-level effects that reduce the welfare of all individuals in fragmented populations through reduced genetic diversity and mate choice. Hedgehogs injured by vehicles may survive with severe trauma, facing prolonged suffering before death or rescue. Preventing road deaths through speed reduction, wildlife crossing infrastructure and habitat management addresses both individual and population welfare simultaneously.

What You Can Do

Drive slowly at night in rural and suburban areas during hedgehog active season
Support campaigns for wildlife underpasses on roads through hedgehog habitat
Create hedgehog-friendly gardens connected to neighbours through small fence holes
Report road-killed hedgehogs to citizen science initiatives tracking mortality patterns
