The primary aim of this study was to compare the composition of primary tree species in secondary forests of different disturbance intensity (clearance occurrences), with nearby relatively undisturbed forest in Laos. The juvenile cohort of tree species individuals was chosen for the basis of analyses as the composition of this cohort most likely predicts the future composition of the maturing forest. Pioneer species were excluded from the analysis.Diversity indices between remnant and fallow forest communities were compared, and compositional analysis to further investigate differences between primary and secondary forests was conducted
