Hedgehog numbers have declined dramatically in the UK, with road traffic, habitat loss, and garden practices among key causes.
Declining hedgehog populations mean fewer individuals living longer, healthier lives in appropriate habitat. Road casualties are particularly welfare-relevant, with injured hedgehogs often dying slowly. Hedgehogs with access to connected gardens, pesticide-free lawns with invertebrate prey, and safe hibernation sites have significantly better survival and reproductive success. Small changes by many gardeners cumulatively create meaningful habitat improvements.
