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 Canarium subulatum
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.
