Short summary
We examined the variables controlling fire severity and the amount of vegetation burnt during wildfires and prescribed burns. Fire severity varied strongly within and between wildfires in relation to fire-weather conditions and vegetation type. The amount of surface vegetation burnt was a function of the amount present pre-fire, whilst moss layer consumption related to prolonged dry periods. Moss flammability may explain the higher carbon-release during wildfires compared to prescribed burns.
