| Research Abstract |
Vegetation changes of tropical seasonal forests in Thailand was investigated using wood charcoal produced by forest fire and opal phytoliths. Forest fire occurred in Thailand at least 10000 years ago. The frequency of fire seemed to affect the forest vegetation: frequent fire induced deciduous dipterocarp forests, which were replaced with mixed deciduous forests, and then with evergreen forests with decreasing forest fire. Tropical seasonal forests were considered to be distributed to lower latitude area compared to the present distribution. Opal phytolith analysis used in this study was useful in studying past vegetation changes.
