Hedgehog Urban Survival and Road Mortality

European hedgehogs face mounting pressures from urban expansion, road traffic, and garden hazards. Understanding their welfare needs can help communities create safer environments for this beloved but declining species.

Key Facts

Hedgehog populations in the UK have declined by over 50% since 2000
Road traffic kills an estimated 100,000 hedgehogs annually in Britain alone
Garden chemicals and slug pellets cause secondary poisoning in hedgehogs
Hedgehogs travel up to 2 km per night foraging, crossing multiple gardens and roads
Fencing and walls fragment hedgehog habitat, preventing essential movement
Hedgehogs are nocturnal and rely heavily on smell and hearing to navigate
A single female hedgehog may raise two litters of 4-5 hoglets per year

Welfare Considerations

Urban hedgehogs face chronic stress from habitat fragmentation and novel hazards. Road strikes cause traumatic injuries including broken limbs and spinal damage. Surviving hedgehogs admitted to wildlife hospitals show signs of dehydration, malnutrition, and secondary infections. Garden hazards including netting, ponds, and strimmers injure thousands annually. The cumulative effect of these pressures on hedgehog welfare is significant, as animals must navigate increasingly hostile environments to meet their basic needs for food, shelter, and mates.

What You Can Do

Create a 13cm gap in garden fences to allow hedgehog passage between gardens
Avoid using metaldehyde slug pellets, which poison hedgehogs through secondary ingestion
Check grass and leaf piles before using strimmers or bonfires
Provide a ramp or gentle slope in steep-sided garden ponds
Install a hedgehog house with dry leaves and straw for shelter
Drive slowly at night on rural and suburban roads
Support wildlife hospital hedgehog rehabilitation programs
