Wild Hedgehog Population Decline Welfare

UK hedgehog populations have declined by over 50% since 2000, with surviving individuals facing habitat fragmentation, road mortality, and secondary poisoning — each cause involving significant individual suffering.

Key Facts

UK hedgehog population estimated at under 1 million, down from 30 million in 1950
Road traffic is the leading cause of hedgehog mortality
Slug pellets containing metaldehyde cause painful deaths before bans
Habitat fragmentation isolates populations and reduces foraging range
Garden fencing without gaps prevents hedgehog movement between territories

Welfare Considerations

The decline of hedgehogs represents both a conservation crisis and a welfare emergency. Individual hedgehogs struck by vehicles often do not die instantly, suffering from internal injuries and shock. Secondary poisoning from rodenticides and pesticides causes slow, painful deaths. Individuals isolated in fragmented gardens may face food shortages. The welfare dimensions of population decline are often overlooked in conservation discourse — each declining individual is also a suffering individual.

What You Can Do

Create a 13cm hole in your garden fence to allow hedgehog movement
Stop using slug pellets and opt for physical barriers or wildlife-safe alternatives
Drive slowly at dusk and dawn when hedgehogs cross roads
Leave wild corners of gardens with leaf piles for hedgehog nesting
Donate to British Hedgehog Preservation Society and local rescue centers
