Wild Hedgehog Decline Welfare | Animal Welfare Hub

Hedgehog populations have declined by at least 50% since 2000 in Britain, with welfare implications for surviving individuals in increasingly fragmented habitats.

Key Facts

UK hedgehog populations have fallen from approximately 30 million in the 1950s to under 1 million
Road mortality, badger predation pressure, and loss of foraging habitat drive declines
Hedgehogs require territories of 10-20 hectares for viable foraging
Garden habitat can be significantly improved by providing corridors and food sources
Hedgehog Street campaign promotes garden connectivity through fencing holes

Welfare Considerations

Population decline has direct welfare implications for individual hedgehogs: as habitat becomes fragmented, animals must travel further to find food, increasing road crossing frequency and energy expenditure. Hedgehogs in degraded habitats enter autumn in poor body condition with insufficient fat reserves for hibernation, increasing winter mortality risk. Individual welfare interventions — providing food, water, and hibernation materials; installing hedgehog highways; avoiding use of slug pellets — help specific individuals while contributing to broader population recovery. The connection between landscape-scale conservation and individual animal welfare is direct.

What You Can Do

Install a hedgehog highway (13cm hole) in your garden fence
Provide water and supplementary food during dry summers and late autumn
Avoid metaldehyde slug pellets and other pesticides that harm hedgehogs
Join Hedgehog Street and record sightings to support population monitoring
