Hedgehog Welfare and Conservation: Helping Britains Most Beloved Mammal

Hedgehog populations have declined by over 50% in Britain since 2000, driven by habitat loss, garden fragmentation, and road mortality. Understanding the causes and solutions helps people take effective action.

Key Facts

Britain has lost over half its hedgehog population since 2000, with continued decline in rural areas
Urban hedgehogs are declining more slowly than rural populations, partly due to garden feeding and habitat
Road mortality kills an estimated 100,000 hedgehogs annually in Britain alone
Garden fencing creates population isolation -- linking gardens with 13cm holes enables hedgehog movement
Badger predation can limit hedgehog populations in areas with high badger density, creating management conflicts
Hedgehog Street has mapped garden corridors across Britain using citizen science data from over 100,000 participants
Mild winters caused by climate change disrupt hedgehog hibernation, causing energy depletion and juvenile mortality

Welfare Considerations

Hedgehog welfare issues are concentrated in the transition from rural to suburban and urban environments. Road deaths are acute welfare events causing significant numbers of deaths. Isolation in individual gardens without connected habitat causes nutritional stress as animals cannot access sufficient territory. Mild winters that interrupt hibernation cause genuine welfare harm through energy depletion without adequate food to replenish reserves. These are largely preventable through coordinated action that most garden owners can participate in -- linking gardens, reducing pesticides, and providing supplementary food.

What You Can Do

Create a hedgehog hole (13cm x 13cm) in your fence to link your garden to neighbouring habitat
Reduce or eliminate slug pellet and pesticide use in your garden to maintain invertebrate prey for hedgehogs
Check bonfires and compost heaps before lighting or turning -- hedgehogs shelter in these
Join Hedgehog Street and record your hedgehog sightings to contribute to national monitoring
Support The British Hedgehog Preservation Society through donation or volunteering
