The authors examined the effects of initial fire severity on subsequent fire severity and also how the pattern of burn severity patches is affected by initial burn conditions.
The authors found a positive feedback between the initial severity of a fire and the severity of a later reburn, especially concerning high severity forest fire. Conversely, low- or moderate-severity fires may regulate future fires to similar severities, which follows historical patterns of frequent, low-severity fires in dry coniferous forest systems.
