The species composition and zonal distribution of mangroves in five research sites viz., Kapa, Masanpa, Panadoung, Kywe Ka Yan and Kyauk Phyar from Myeik coastal areas were studied from December 2017 to July 2018. Transect lines in landward, seaward and shoreline, and plots based on Point Center Quarter Method (PCQM) were used. A total of 21 species of true mangrove were recorded. Rhizophora apiculata and R. Mucronata were the most dominant species in the study sites, especially in the seaward areas. Among the recorded species, Aegiceras corniculatum, Avicennia officinalis, R. apiculata, R. mucronata, Sonneratia alba and Nypa fruticans were distributed in all study sites. Bruguieragy mnorhiza and B.cylindrica, were recorded only in shoreline areas and Heritiera littoralisis was found only in landward areas in all study sites. Among the study sites, Kapa has been designated as the highest species composition, representing 17 species, whereas Kyauk Phyar, representing 12 species as the lowest species composition. The environmental parameters of mangrove forests were also provided in all study sites. The various salinity ranges significantly controlled the distribution and growth of mangrove plant species in the study sites.
