Estimasi Karbon Tersimpan Pada Hutan Rakyat Di Pekon Kelungu Kabupaten Tanggamus

Abstract

The increasing rates of forest degradation and deforestation has been decreasing carbonstocks of forest. Pekon kelungu is one of the village that developing the community forestusing agroforestry system that is also has a function as a carbon stock. The research wasconducted to determine the dominant vegetation and to predict the amount of above groundcarbon stock at the community forest in Pekon Kelungu. The Important Value Index (IVI) wascalculated to measure plants domination.  Allometric equation was used to measure carbonstored for living and dead tree, volume formulas for necromass and Biomass ExpansionFactor formula for litter and seedlings. Durian, cacao and campaca is the dominat tree poleand seedling, respectively. The total carbon of above ground biomass of community forest inPekon Kelungu is amounted to 101,61 ton/ha. Carbon stored on tree component is amountedto 99,92 ton/ha, necromass is amounted to 0,81 ton/ha, litter is amounted to 0,87 ton/ha andseedling is amounted to 0,02 ton/ha.Keyword : carbon stock,community forest, IVI,
