The aim of this research was to collect basic data of mangrove ecosystem which covered inventory of biodiversity and ecology structure by using primary and secondary data. Primary data of mangrove forest ecosystem has been collected by line transect method while secondary data was collected by study literature and previous study report. The result showed that there were 17 types of primary mangrove and 18 types of secondary mangrove. The main value indeks in every study area indicated that in the study area I and IV, Xylocarpus granatum had high value as 104,53 and 104,22 subsequently.
