Carbon stock and vegetation estimation the abandoned pond, Pulau Sembilan, North Sumatra, Indonesia

Abstract

Abstract The purpose of the study was to determine the species vegetation and carbon stock assessment derived from abandoned aquaculture ponds. Analysis of plant (tree, sapling, and seedling) was performed at Pulau Sembilan, Langkat, North Sumatra, Indonesia. The stage of the seedlings, saplings, and trees was analyzed from four transects. Each transect contained 100 m in length. Each estimated plot of a total of four transects comprised of 30 plots. The abandoned pond was dominated by Rhizophora apiculata and Bruguiera parviflora, the lowest on the species of Morinda citrifolia and Rhizophora mucronata. The diversity index of Shannon-Weiner was 1.44-1.72. The total biomass in the pond was 4,557.43 k/ha with a carbon potential of 2.10 tons/ha.
