Wild Hedgehog Welfare and Decline

British hedgehogs have declined by over 50% since 2000, with habitat loss, road mortality, and garden management practices threatening the welfare of surviving populations.

Key Facts

UK hedgehog populations have declined from approximately 30 million in the 1950s to an estimated 1 million today
Road deaths kill an estimated 100,000-300,000 hedgehogs annually in the UK — a major population pressure
Slug pellets containing metaldehyde and methiocarb poison hedgehogs that consume poisoned slugs
Garden fences prevent hedgehog movement between feeding and resting areas — connected gardens are essential habitat
Hedgehogs need to range 1-2km per night for food — fragmented suburban gardens cannot support adequate foraging territory
Litter, especially elastic bands, netting, and tin cans, causes entanglement injuries affecting a significant proportion of rehabilitated hedgehogs
Bonfire building without checking for hedgehogs sheltering inside results in hedgehog deaths during Guy Fawkes and other celebrations
Hedgehog Street campaign has registered over 100,000 hedgehog-friendly gardens with holes in fences for corridor creation

Welfare Considerations

Wild hedgehog welfare reflects the broader challenge of sustaining viable wildlife populations in human-modified landscapes. Surviving individual hedgehogs face road mortality risk, poisoning from garden chemicals, entanglement in garden litter, and the nutritional stress of operating in fragmented habitats without adequate foraging territory. Each of these welfare harms is largely preventable through accessible actions: switching to wildlife-safe slug control, creating fence holes, checking bonfires, and removing entanglement hazards. The cumulative impact of these individual garden decisions across millions of properties creates the landscape that determines whether hedgehog populations persist or continue declining.

What You Can Do

Create a 13cm hole in garden fences to allow hedgehog movement between gardens
Switch to wildlife-safe slug control methods and avoid all pesticide use that could harm hedgehog prey or hedgehogs directly
Check bonfires for hedgehogs before lighting and leave leaf piles undisturbed in corners as hibernation habitat
Remove netting, elastic bands, and other entanglement hazards from garden areas accessible to wildlife
