Influences of abiotic and biotic factors (climate, soils, vegetation types, plant functional types) on fire regimes via four “switches” (fuels, fuel availability [amount, structure, continuity], fire weather, and ignitions). Plant functional types have similar responses to the environment and effects on ecosystem functioning. Potential effects of changing climate, human activity, and atmospheric CO₂ are indicated by dashed lines. Figure modified from Bradstock 2010
