Road traffic is a significant and quantifiable cause of hedgehog mortality, and the patterns of road casualty occurrence point to specific interventions that could save substantial numbers of animals.
Hedgehogs struck by vehicles experience traumatic injury. Many do not die immediately, suffering from internal injuries on the road verge before death. The predictable seasonal and geographic patterns of casualties mean targeted interventions at known high-mortality locations could prevent large numbers of deaths. Road casualties are not random events but preventable through infrastructure modification and driver awareness.
