Wild Hedgehog Decline: Habitat Loss and Road Mortality

European hedgehog populations have declined dramatically over recent decades, with road deaths, habitat fragmentation, and agricultural intensification among the primary causes. Conservation efforts are gaining momentum.

Key Facts

UK hedgehog populations have declined by around 50% since the year 2000
Hedgehogs can travel up to 2 miles per night foraging for food
Road traffic kills an estimated 100,000-300,000 hedgehogs annually in the UK alone
Garden fragmentation caused by fencing is a major barrier to hedgehog movement
Hedgehogs consume large quantities of beetles, earthworms, and slugs — helping gardens naturally
Use of pesticides reduces hedgehog prey availability significantly
Hedgehog hibernation runs roughly from November to March in temperate climates
A simple 13cm x 13cm hole in garden fences allows hedgehog passage

Welfare Considerations

Declining hedgehog populations mean individual animals face greater difficulty finding food, mates, and safe refuges. Injured hedgehogs commonly present at wildlife hospitals with road injuries, garden tool wounds, and bonfire-related burns. Individual welfare and population-level conservation are closely linked here — every hedgehog that survives and breeds contributes to population recovery. Gardens with piles of leaves for hibernation, reduced pesticide use, and fence gaps for movement can dramatically improve local hedgehog survival.

What You Can Do

Create a hedgehog highway by cutting a 13cm gap in garden fences
Leave areas of your garden wild with log piles and leaf heaps for shelter
Stop using slug pellets and pesticides that reduce hedgehog prey
Check grass before mowing and bonfires before lighting
Report hedgehog sightings to local wildlife recording schemes
Support hedgehog rescue organizations and wildlife hospitals in your area
