Dynamic and structure of lowland dipterocarps forest after fire in Bukit Suharto, East kalimantan, Indonesia

Approximately 3.5 million ha of lowland forest in Indonesia was heavily burnt
in 1982 due to forest fire associated ENSO. This catastrophe were reoccurred heavily
in 1998 cause severe damaged of 1.5 million ha forest area. Meanwhile, 520,000 ha
were destroyed included those in Bukit Suharto Education Forest covering no less than
4205 ha. It was about 21% of total area. This research reported the impact of forest
fire on forest dynamic after 4 years. The research plots was conducted in lowland
dipterocarps forest after fire of 9 ha experiment plots. Research plots categorized into
3 subplots of Light Felling (LF) plots (dbh > 50 cm), Heavy Felling (HF) with dbh >
30 cm and control. The result showed that average tree density/ha after prescribed fire
were 13.9%, 20.9%, and 29.1% in LF, HF and control respectively. Mean while the
diameter distribution of the stand were changed. Considering this severe damage,
forest recovery toward normal (climax) stand would take longer time, so that
rehabilitation is compulsorily important.
