Urban hedgehog populations depend on connected garden networks, with garden boundaries being the most important structural barrier to range and survival.
Urban garden connectivity is the most important structural welfare intervention for hedgehogs in towns and cities. Without movement between gardens, individual hedgehogs cannot access sufficient food, shelter, and mating partners within a connected habitat network. Solitary hedgehogs trapped in isolated garden fragments face malnutrition and reproductive failure. Each hedgehog highway hole creates the possibility of connection that improves the welfare of all hedgehogs using that network.
