Five 0.5-ha plots were subjected to different levels of overstory removal of 0 per cent, 8 per cent, 28 per cent, 45 per cent and 55 per cent. The regeneration population 3 years after overstory removal was similar in density and composition to the population before overstory removal except removal was similar in density and composition to the population before overstory removal except for an unidentified liana that was not found in 1986 but was moderately abundant in 1989. Regeneration of commercial tree species (tolerant and intolerant), noncommercial tree species, and nontree species was compared with the residual basal area and percentage of basal area removed. Frequency of intolerant commercial species increase as residual basal area decreased. Frequency of tolerant commercial species was not affected by residual basal area or percentage of basal area reduced.
