The old secondary forest was dominated by Cratoxylon arborescens
(Hypericaceae) and Pternandra caerulescens (Melastomataceae), whereas the primary forest was dominated by dipterocarps.
The Shannon–Wiener diversity index was 3.40 for the old secondary forest plots and 4.17 for the primary forest plots; the
Jaccard’s coefficient of similarity was 24%. Mortality, recruitment, turnover and tree growth rates were greater in the old
secondary forest.
