Mangrove species composition, density, DBH, total basal area, and tree biomass fromthe CMNP are shown in Table 2. Themangrove forest can be divided into three vegetation zones based on the species composition, being dominated by A. alba, A. officinalis, R. apiculata, and S. caseolaris in the fringe forest, by R. apiculata, B. parviflora and A. alba
in the transitional forest, and by R. apiculata, A. alba, A. officinalis, and B. parviflora in the interior forest. The highest mangrove tree density was expressed in the fringe forest, followed by the interior and transitional forests (Table 2). Overall, mean tree biomass markedly increased from the fringe toward the interior forest (Table 2), and the total basal area was the highest in the fringe forest andwas the lowest in the transitional forest.
