This swamp is a mixed community dominated by Aegiceras corniculatum , Heritiera littoralis , Excoecaria agallocha , Kandelia candel, Bruguiera gymnorrhiza , with importance values of 37.88, 28.19, 14.33, 11.33 and 8.27 respectively. The community’s mangrove species diversity and evenness , as based on the Shannon-Wiener Function, were 1.44 and 62.01%, which were lower than those of the south su-tropical evergreen broad-leaf forest community but its ecological dominance (0.26) was higher.
