Tree Diversity and Community Composition of the Tutong White Sands, Brunei Darussalam: A Rare Tropical Heath Forest Ecosystem

Table 3

Mean diameter at breast height (DBH), mean basal area, and total basal area of trees in six plots in the Tutong White Sands. Total basal area of a plot was calculated from the sum of basal areas of all trees within the plot. Different superscript letters indicate significant differences in plot mean values at α = 0.05.
