The survey is conducted using the Standard Line Transect Method to classify the species inhabiting each area, and the mangrove tree height, crown cover ratio, regeneration per ㎡, and girth at breast height(GBH) are measured using the field guide method developed by Primavera and BRAR. As a result of the investigation, there are total of five mangrove species(Avicennia marina, Rhizophora stylosa, Ceriops tagal, Excoecaria agallocha, Pemphis acidula), of which Excoecaria agallocha and Pemphis acidula are excluded from the measurement because they are found outside the investigation area.
