Urban Hedgehog Welfare and Garden Hazards

Urban hedgehogs face a range of anthropogenic hazards in garden environments that cause preventable injury and death, alongside population pressures from habitat loss.

Key Facts

UK hedgehog populations have declined by up to 50% since the year 2000
Garden netting, ponds without exit ramps, and bonfires kill thousands of hedgehogs annually
Slug pellets containing metaldehyde and mesurol are toxic to hedgehogs that eat poisoned slugs
Hedgehogs travel up to 3km per night requiring corridors between connected garden habitats
Solid garden fencing prevents hedgehog movement - 13cm gaps at ground level allow passage
Hedgehogs are effective biological pest controllers consuming slugs, beetles, and caterpillars

Welfare Considerations

Urban hedgehog welfare suffers from a thousand individual garden management decisions that collectively create a hazard-filled landscape. Ponds without wildlife ramps drown hedgehogs that fall in attempting to drink. Garden netting left at ground level entraps hedgehogs whose spines prevent withdrawal. Bonfires built in autumn are frequently constructed over hibernating hedgehogs who cannot escape. Each of these hazards causes suffering and death that is entirely preventable with simple modifications. The metaldehyde slug pellet route is particularly pernicious - hedgehogs are poisoned indirectly through eating dying slugs, causing acute suffering. The cumulative impact of multiple hazards across typical urban garden landscapes creates serious barriers to hedgehog population recovery.

What You Can Do

Create a 13cm gap at the base of garden fences to allow hedgehog passage
Install wildlife exit ramps in garden ponds and check netting before leaving it out
Always check bonfire bases before lighting in autumn and winter
Switch to ferric phosphate slug pellets or non-toxic pest control methods
