POTENSI DAN KANDUNGAN KARBON HUTAN MANGROVE DI KARANGSONG, INDRAMAYU, JAWA BARAT

The location of this study was originally abandoned ponds. The research aims to obtain information about potential species and carbon content of mangrove forests in the Karangsong, Indramayu, West Java. The plots were made in three places consisting of 12 samples of 10 x 10 m for tree inventory, saplings and seedlings with 20 m plot spacing. The results showed that in the mangrove forest of 15.9 ha, eight species were found. The dominant species for tree and sapling stages are Avicennia marina Blume with IVI 279.74% and 156.03%, respectively. The dominant species for  seedling stage is Rhizophora stylosa Griff. with IVI 21.32%. Regeneration in mangrove forests is quite good. The biomass and carbon content at study site were dominated by R . mucronata Lam. with a biomass of 72.48 tons/ha (equivalent to 36.24 tons C/ha or 133 tons of CO 2 /ha) and A . alba Blume of 20.60 tons/ha (10.30 tons C/ha equivalent to 37.80 CO 2 /ha). Total biomass at the study site was 103.42 tons/ha (equivalent to 51.71 tons C/ha or 189.78 tons CO 2 /ha).
