The research about the understorey plant community in the Lore Lindu National Park Central Sulawesi has been conducted from March 2004 to February 2005. The research used multiple plots by survey methods with plot size 2X2 m as much 25 plots each forest type. There were 2 types of observed forest namely: “wana” (primary forest) and “pangale” (primary disturbed forest). The result showed the understorey plant composition was differ in two forest types observed. “Wana” were dominated by Pilea wightii (Urticaceae), Curculigo orchimoides (Hypoxidaceae), Chionanthus ramiflorus (Oleaceae) Callophyllum soulatri (Clusiaceae) whereas “pangale” were dominated by Diplazium angustippina, Zizhipus sp (Rhamnaceae), Freycinetia angustifolia, Castanopsis accuminatissima. The Shanon diversity index of wana (3.25) was higher than pangale (3.06).
