2. Total devastation after the forest fires of 1997-98 in East Kalimantan. Around 5.2 million hectares were burnt. Burnt peat swamp forest (left) and unburnt forest (right). Post-fire regeneration of tropical trees is very slow and patchy due to seed loss, grass invasion, increased fire susceptibility and thin bark of trees.

4. ‘Whole of Island’ Relationship between Area Burnt and Prior Rainfall • PAB month i= exp B1 × rainfall_lag k, • where k = 0 (present month’s rainfall), k=1 (average of current and previous month’s rainfall),…, and k=11 (average of last 12months rainfall, including current month’s rainfall). • Highly negative B1 values indicate a strong negative correlation between fire and rainfall.

5. Spatial Distribution of Relationship between Area Burnt and Prior Rainfall Strong negative correlation between fire and rainfall Weak correlation between fire and rainfall
