Hedgehog Garden Welfare: Mortality Risks and Habitat Improvements

Hedgehogs face numerous hazards in domestic gardens including strimmers, ponds and bonfire piles. Simple changes can dramatically reduce garden mortality and support hedgehog welfare.

Key Facts

UK hedgehog populations have declined by over 50% since the year 2000, with garden loss being significant
Garden strimmers and lawnmowers kill thousands of hedgehogs each year, particularly those sheltering in long grass
Garden ponds without escape ramps are drowning traps for hedgehogs attempting to drink or cross
Bonfire piles built in autumn frequently shelter hibernating hedgehogs and are a major mortality cause
Slug pellets containing metaldehyde and iron phosphate both harm hedgehogs directly and by poisoning prey

Welfare Considerations

Garden hazards cause significant acute suffering for individual hedgehogs. Strimmer injuries are among the most horrific wildlife casualties seen by rehabilitators, causing severe lacerations to legs, faces and abdomens that require intensive veterinary care and often prove fatal. Drowning in ponds represents prolonged distress. Bonfire burning of occupied hibernation sites causes death by burning or smoke inhalation. At the population level, these garden mortalities compound habitat fragmentation and food loss to create a cumulative welfare and conservation crisis for a species already under severe pressure from agricultural intensification.

What You Can Do

Check thoroughly for hedgehogs before using a strimmer or lawnmower, especially in long grass
Build a bonfire pile only the day you intend to light it, or check it carefully before lighting
Install a hedgehog escape ramp in any garden pond
Create a hedgehog hole in garden fences to allow free movement between gardens
Eliminate slug pellets and choose pet-safe alternatives such as copper tape or beer traps
