  1. The sixteen most abundant species accounted for 51% of total tree species abundance in the overstory and 72% in the regeneration layer. The 16 species of the overstory that accounted for 51% provide 67% of the trees in the regeneration layer. Abundance columns show the number of tree species individuals across the 90 sample plots and 450 sub-sample plots. The percentage column was calculated by dividing the abundance of each species by all tree species abundance. Accumulation aggregated the percentage column from the first to the last species. The Group column classifies species as common species and threatened species and newly occurred species. Rank shows the ranking of the species in terms of their share of total abundance for the overstory and the regeneration. Species are sorted by the abundance of the overstory species from largest to smallest value. Sp1 to Sp5 are unidentified species
