Summary: Although the current fire weather conditions do under normal conditions not favour extensive land clearing by fire or escaping wildfires in Indonesia, the consequences of the large wildfires of 1997-98 must been taken into consideration. These fires had caused extensive degradation of primary and secondary forests along with the spreading of "alang-alang" (Imperata cylindrica) grasslands. These grasslands facilitate the spread of uncontrolled fires over large areas.
