Hedgehog Welfare: Garden Visitors in Decline

European hedgehog populations have declined by over 50% since 2000. Understanding their needs and reducing garden and road hazards can meaningfully support their welfare and survival.

Key Facts

European hedgehog populations have declined by an estimated 50% in the UK since the year 2000.
Road mortality is estimated to kill hundreds of thousands of hedgehogs annually in the UK alone.
Hedgehogs travel up to 2 km per night in search of food; garden fences fragment their foraging range critically.
Slug pellets containing metaldehyde or methiocarb are toxic to hedgehogs and kill individuals indirectly through prey contamination.
Hedgehogs are insectivorous and rely on a diverse invertebrate community; pesticide use reduces their food supply.
Hibernation disruption from mild winters caused by climate change can lead to starvation in winter-active individuals.
Hedgehog highways — 13cm x 13cm holes in garden fences — allow movement between gardens and significantly expand foraging range.

Welfare Considerations

European hedgehog welfare is primarily threatened by habitat fragmentation and human-caused hazards in the landscape they share with people. Road mortality causes traumatic deaths on a large scale; garden boundary fences prevent the wide-ranging foraging that hedgehogs need to maintain body condition for hibernation. Pesticides reduce invertebrate prey availability and directly poison hedgehogs who consume contaminated slugs. These threats are largely addressable through individual and community action: creating hedgehog highways between gardens, eliminating pesticide use, providing supplemental food and water in dry periods, and taking appropriate road-crossing precautions. Hedgehog welfare is intimately connected to the broader cause of garden biodiversity and insect-friendly gardening.

What You Can Do

Create a hedgehog highway by cutting or drilling a 13cm x 13cm hole at the base of your garden fence.
Eliminate pesticide and slug pellet use in your garden to protect hedgehog food sources.
Provide fresh water and supplemental food (meaty cat or dog food) for hedgehogs visiting your garden.
Check compost heaps and piles of leaves before disturbing them to avoid harming hibernating hedgehogs.
Support hedgehog rescue organizations and rehabilitation centers in your area.
