Hedgehog populations are declining sharply in many countries, driven by habitat fragmentation, road deaths, and garden hazards that concentrated welfare interventions can address.
Individual hedgehogs suffer acutely from road collisions, pond drowning, garden machinery injuries, and slug pellet poisoning. Those who survive such injuries often require months of rehabilitation. At the population level, habitat fragmentation means hedgehogs cannot find mates or sufficient food, leading to chronic poor condition and reduced reproductive success. The welfare and conservation solutions converge: connected gardens, wildlife-friendly hazard reduction, and the elimination of toxic chemicals benefit both individual animals and populations. Urban areas can serve as hedgehog conservation strongholds if residents coordinate habitat improvements.
