Lightning-caused fires (LCFs) and fire environments influenced by thunderstorms are increasingly implicated in extreme wildfire events around the world, with devastating consequences to society and the environment. However, the disaster potential inherent to LCFs is often neglected, especially where the fire regime is determined mostly by anthropogenic ignitions. Such disconnect between perceived risk and actual risk is illustrated with the Iberian Peninsula, where thunderstorm-driven wildfires are comparatively rare but have resulted in large-scale burning and considerable loss of human life. Even low LCF regions should embrace fire management strategies able to cope with LCFs.
