Citizen science roadkill recording programmes are revealing the scale of road mortality for wildlife and informing mitigation measures to reduce its impact.
Wildlife roadkill represents a massive source of animal suffering, with animals struck at high speed suffering traumatic injuries and deaths. The visibility of roadkill means it is one of the most immediate wildlife welfare issues the public encounters. Citizen science recording programmes transform individual observations into population-level data that informs mitigation. Installing wildlife crossing structures, adaptive speed limits during peak movement seasons, and wildlife-friendly drainage can reduce casualties significantly when targeted using roadkill data.
