The most abundant and frequent tree species were firetolerant dipterocarps. D. obtusifolius (24% of all measured stems)
and D. tuberculatus (13%) occurred in 95% of all focal tree plots, Shorea species (S. obtusa and S. siamensis, 20% of all stems) in 86%.Themost common non-dipterocarp tree was Canariumsubulatum Guillaumin (Burseraceae; 90% of all plots) but it was much less abundant (6% of all stems). In the dense ground layer, Kyasuma gras (Pennisetum pedicellatum Trin.), the Ginger lily Globba schomburgkii Hook. f. and the leguminous climber Spatholobus
parviflorus Kuntze were most frequent. The climbing fern Lygodium flexuosum (L.) Sw. was typically associated to wetter
sites and the noticeable ant harboring epiphyte Dischidia nummularia R. Br. to dry sites.
