Results from the final reduced model of proportion area burnt for the Mudumalai landscape.
(a) Effect of wet season rainfall on proportion area burnt in a year keeping early dry season rainfall constant at its mean value (112mm) and with previous year’s proportion area burnt held constant at three values– 0.49 (maximum of the range; solid line), 0.21 (mean of the range; dotted line) and 0.0 (minimum of the range: dashed line). (b) Proportion area burnt for a year at different values of wet season rainfall keeping previous year’s proportion area burnt constant at its mean value (0.21) and early dry season rainfall held constant at three values– 195mm (maximum of the range; solid line), 112mm (mean of the range; dotted line) and 22mm of rainfall (minimum of the range: dashed line).

Fig 2.
Results from the final reduced models of proportion area burnt for each of the moisture regimes (a) MR1: ≥1400mm (b, c) MR2: 1400-1200mm (d) MR3: 1200-1000mm and (e) MR4: ≤1000mm. The three lines in (b) represent area burnt at three levels (maximum, mean and minimum) of the range of the previous year’s proportion area burnt when early dry season rainfall is held constant at the mean (112mm) for MR2. The three lines in (c) represent area burnt at three levels (maximum, mean and minimum) of the range of early dry season rainfall when the previous year’s proportion area burnt is held constant at the mean (0.21) for MR2. The three lines in (d) and (e) represent area burnt at three levels (maximum, mean and minimum) of the range of early dry season rainfall particular to the respective regimes.
