A total of 26 species belonging to 22 genera and 15 families were recorded from the mangrove areas along the Thaung-ga-done creek, Pyapone Township, Ayeyawady Region. The recorded families included Acanthaceae, Meliaceae, Avicenniaceae, Leguminosae, Asclepidaceae, Sterculiaceae, Palmae and Sonneratiaceae. Among those, Avicenniaceae family represented the highest diversity and abundance in the study areas followed by Rhizophoraceae family and Acanthaceae family. Along the creek, Avicennia offinalis, Acanthus ebractraus and Bruigyira cylindrica species were dominated. However, Derris trifoliata and Sesapenia sp. were also represented as the abundance species among the mangrove associate species. Seven transect lines were laid along the creek. Simpson's index and Shannon Weiner index were used as tools for measuring the diversity and abundance of the plant species. Highest diversity value by Simpson's index was 0.82 in transect 3 and by Shannon Weiner index was 2.78 in transect 3.

Keywords : Delta, Simpson's index, Shannon Weiner index.
