Urban and suburban gardens are important hedgehog habitats, and simple changes by householders can dramatically improve individual welfare and population health.
Hedgehogs entangled in garden netting suffer from restriction injuries, lacerations, and slow starvation if not discovered quickly. Animals trapped in garden ponds without a ramp to escape drown after exhaustion. Hedgehogs run over by strimmers in long grass suffer severe lacerations that require emergency veterinary treatment. Woken from hibernation in bonfires die from hypothermia or burns. These are entirely preventable with simple awareness changes. The welfare impact of multiple garden hazards on a declining species is significant at population level.
