Understanding of forest recovery process after logging is crucial for sustainable forest management and biodiversity conservation of tropical forests. To clarify the effect of logging on the recovery process of tropical forest, we compared tree dynamics among three lowland forest stands with different logging histories in Borneo. A 0.25-ha census plot was established in primary forest and two logged forests. The old and new logged forests were subject to selective logging in 2005 and 2015, respectively. The dominant tree species were dipterocarps in the primary forest, and Macaranga species in the two logged forests. Stem diameter growth rate was higher in the new logged forest compared with the primary and the old logged forests. Focusing on Macaranga species, the new logged forest had smaller trees with higher diameter growth rate compared with those in the old logged forest. Tree mortality rate and recruitment rate were higher in the new logged forest than the primary and old logged forests. Dipterocarp saplings were observed under Macaranga tree canopies in the old logged forest. Our results suggest that the new logged forest is still at stand initiation phase under canopy gaps and the old logged forest is at the subsequent stem exclusion phase.
