British hedgehog populations fell from an estimated 36 million in the 1950s to under 1 million today. Rural declines are driven by agricultural intensification. Urban populations benefit from food availability, reduced predator pressure, and milder microclimates. Urban hedgehogs represent a conservation and welfare opportunity.
Urban hedgehogs face specific welfare threats: road traffic mortality (100,000+ killed annually on UK roads), garden hazard entrapment (netting, litter, bonfires, strimmers), and poisoning from slug pellets containing metaldehyde or methiocarb. These causes of suffering are largely preventable through individual action.
Hedgehog-friendly gardens provide: access holes in fences and walls (13cm square), log and leaf pile shelters, pesticide-free slug management (beer traps, nematodes), and ponds with ramps for escape. 'Hedgehog highways' — connected garden networks — allow territorial ranging of 1-2km nightly.
Supplemental hedgehog feeding (meat-based cat or dog food, not bread or milk) supports welfare during drought when invertebrate food is scarce. Dedicated hedgehog feeding stations protect food from domestic cats and foxes while allowing hedgehog access. Coordinated neighborhood feeding programs improve population welfare.
Animal crossings designed for hedgehogs (culverts at road edges), wildlife warning signs, and citizen science roadkill monitoring help manage traffic mortality. Community-led campaigns for slower urban traffic speeds have welfare benefits beyond hedgehogs.
British Hedgehog Preservation Society operates a rescue referral network for injured and orphaned hedgehogs. Key welfare interventions: rescuing underweight autumn hoglets, treating mange and ringworm, releasing in appropriate habitat. Citizen science reporting (iRecord, Hedgehog Street) generates population data guiding conservation action.
