Short summary
We studied wildfires in the Gran Chaco, one of the world’s largest dry forests, to understand why some fires become much larger than others. By analyzing thousands of fires together with environmental and landscape data, we found that fire size is mainly shaped by topography and vegetation structure, which determine how continuous fuels are across the landscape. Weather and human factors play a secondary role in explaining final fire size.
