Korelasi indeks keanekaragaman dan kerapatan tegakan dengan simpanan karbon mangrove Estuari Perancak

Land use change is a huge threat for mangrove ecosystems,which are known their high carbon sequestration and storage capacity.Vegetation restoration efforts often undertaken, but fail to restore optimal ecosystem sequestration. The forest of Perancak Estuary with history project was made the subject this research. objectives include: (i) estimation biomass sediment stock; (ii) comparison restored, mixed natural mangroves’ total (iii) correlational analysis between stand density diversity indices stock. Nine sampling points were determined within three categories (mixed, natural, restored). Stand characteristics diameter at breast height (DBH) measured allometrically estimate carbon. Sediment analyzed Loss on Ignition (LOI) method. Correlational done Pearson’s correlation coefficient. Total stock 4472,93 tonnes ha-1 (biomass C: 4046,31 ha-1; 426,62 ha-1). Highest value found restored mangroves due contribution C offsetting its low C. Lowest decreased root production increased decomposition in tidal regimes. There strong positive Simpson index has stronger (though non significant) than Shannon-Wiener index.
