Estimation of carbon stock at the mangrove forest of Sangkulirang District, East Kutai Regency, East Kalimantan Province

Abstract

Mangrove forests provide environmental, economic, and social benefits such as fish breeding, lumber production, water purification, recreation, education, and carbon sequestration. Mangroves are important organic carbon sinks, and there is a lot of interest in using them to reduce greenhouse gas emissions. Future climate change and deforestation would have a negative impact on organic carbon storage potential, hence worldwide estimates of future change remain a major research subject. The carbon stock varies by location. The purpose of this study was to estimate the carbon stock of mangroves in Sangkulirang District, East Kutai, East Borneo. Mangrove sediment organic carbon, above-ground biomass, under-ground biomass, and necromass were the parameters studied. Carbon stock was conducted by surveying the mangrove species, diameter, and height on a plot of 20x20m for tree, 10x10m for pole, 5x5 m for sapling, and 2x2 m for seedling. The biomass and carbon stock estimation using an allometric equation. Necromass carbon was conducted by taking a necromas in 1x1m plot and weight them for wet and dry weight. The mangrove carbon estimation method of Indonesian National Standard SNI_7724-2011 was applied in this study. According to the research, the total average carbon in mangroves in Sangkulirang District is 1386,87 Mg C ha-1.
