Abstract

Carbon conservation programs in mangrove ecosystems focus on the growth of mangrove vegetation that is measured based on the amount of carbon present at different tree stages particularly, the seedlings, saplings and mature mangrove trees. This study was aimed to determine carbon percentage of mangrove ecosystems using the SNI 06 – 3730 – 1995 and TAPPI T 211 om 85 methods, and to analyse the mangrove clustering based on carbon percentage. The  results showed that (1) Avicennia spp, Sonneratia spp, Bruguiera spp, Rhizophora spp, Aegiceras spp, Lumnitzera spp, Ceriop spp, Exoecaria agallocha and Xylocarpus granatum had carbon percentages between 45.01-55.54%; (2)  the carbon percentage of mangroves at different growth stages were as follows; seedlings at 16.3-21.2%, sapling at 19.0-28.1%, trees with diameter at breast height (DBH) of 10-20 at 38.1-46.3%, trees with DBH of 20-30 cm at 40.2-51.1% and trees with DBH of 30-40 cm at 49.1-55.2%. The carbon conservation is positively correlated with the carbon sequestration ability and growth of the mangroves.

Abstract

Mangrove ecosystem in Segara Anakan Lagoon (SAL) Cilacap as a typical and specific semiclosed estuary. SAL  is dominated by many species like as Rhizophora spp., Sonneratia spp., Bruguiera spp., Avicennia spp., and other species. The normalized different vegetation index (NDVI) and dominant vegetation index (DVI) are a suitable method to support the mapping analysis of mangrove structure and mangrove density.  This research aimed to develop mapping of mangrove species distribution, density and dominated species using NDVI and DVI.  The method of this research used NDVI analysis using satellite imagery 2017-2020 and domination vegetation with line and quadrat transect method. The results showed that  West Segara Anakan had mangrove dense (25 %), moderate density (25 %), rare density (50%) and East Segara Anakan had mangrove dense (43,86 %), moderate density (47.99 %), rare density (8,24 %).  Based on domination species showed that East Segara Anakan was dominated by Rhizophora stylosa (233-1633 trees ha-1), Rhizophora apiculata (100-1067 trees ha-1), Nypa frutican (50-2775 trees ha-1), whereas West Segara Anakan was dominated by Nypa frutican (565-2333 trees ha-1), Avicennia marina (198-933 trees ha-1), Sonneratia caseolaris  (132-700 trees ha-1) and Avicennia alba (107-1000 trees ha-1). Keywords : Mangrove density, mapping analysis, Segara Anakan Lagoon, NDVI and NDWI
