One  transect of 10 m x 900 m was  constructed perpendicular  to  the sea edge  to know  the pattern  of
mangrove forest communities from the sea edge through the inland area. Then, one sample plot of 50 m x 50 m
was established at each forest community to explore its vegetation structure and soil characteristics.
The results show that in Talidendang Besar area, there are three mangrove forest communities stretching
from the sea edge to the inland, namely Bruguiera parviflora, B. sexangula and B. sexangula-Nypa fruticans.
The soil factors such as pH.EC (electrical conductivity), % K, % Na, C-organic, N-total, NH4 (ammonia), and
CEC  (cation exchange  capacity) were  regarded  important  in  influencing  the  pattern of  the mangrove  forest
communities.
