Study of Biomass in Two Mangrove Ecosystems

This study aims to determine the storage of biomass in mangrove ecosystem Jakarta Bay compared Ambon Bay. research used descriptive quantitative method. Sampling technique using Point Center Quarter Method (PCQM) which was measured around chest height trees (DBH). Data analysis performed an allometric equation where each plant has a specific gravity. The results this indicated that composition species consists 6 species, namely: Bruguiera cylindrica (L.) Bl, Rhizophora apiculata Sonneratia alba Smith, Aegiceras corniculatum Blanco, Avicennia officinalis L, Ceriops tagal. In ecosystem, Bl and Smith had higher values other four species. Meanwhile, Bay, plants is dominated by Smith. subsurface region lower than aboveground biomass.
