The dynamics of variations in carbon biomass in community forest and agroforestry in South Sulawesi

Knowledge of the variation of potential carbon stocks in different types of forests provides information about the capabilities of each forest type in dealing with climate change mitigation. This research was conducted to determine the dynamics of carbon stocks in gofasa plantation community forests and compared to other land use systems in South Sulawesi. The research used sample plots 20 m x 50 m to measure tree biomass and 1 m x 1 m sub plots for undergrowth and litter. The results of the study indicated that there were variations of potential carbon stocks in plantation community forests and agroforestry. Carbon stocks in plantation community forest were varied according to the condition and age of forest stand. The total aboveground carbon stocks in homogenous gofasa stand ranged from 22.34 to 52.65 ton/ha by the difference in stand ages, while in mixed community forest was 77.60 ton/ha. As for agroforestry system, the carbon stocks ranged from 46.40 to 65.89 ton/ha. The dynamics of variations in carbon stocks in plantation community forest and agroforestry were determined by several variables such as species composition, stand age, and stand density. Therefore, a good management of community forests and agroforestry systems will ensure the mitigation of climate changes and environmental preservation through effective carbon storage.
