Carbon Sequestration and Environmental Service Assessment in the Special Purpose Forest Area of Mount Bromo, Indonesia
Resumo: This study aimed to evaluate the carbon and environmental service potential in the natural tourism zone of special purpose forest areas Mount Bromo. The study focused on understanding how this area, with its specific tree compositions and sizes, contributes to carbon absorption and environmental benefits, which can also translate into carbon credits, a form of state revenue. The methodology involved purposive sampling to create observational sample plots (OSP) of varying sizes based on tree diameter. These plots were designed to measure the biomass, carbon potential, and environmental service potential of the trees in a given area. The collected data included the composition of tree species, the number of each type of tree, their diameters, and heights. The study applied specific formulas to determine the potential of biomass, carbon, and environmental services in the area. Key findings revealed a dominance of mahogany trees (83 trees per hectare) among ten identified plant species, indicating a specific but lower biodiversity in this zone. The significant results of the study include the quantification of biomass potential, which was found to be 787.84 tons/ha above-ground and 228.47 tons/ha below-ground, totaling 1016.31 tons/hectare. The study also evaluated the environmental service potential, including CO2 absorption and O2 production. The CO2 absorption capacity of the area was estimated at 1753.04 tons/ha, with a corresponding high O2 production of 1279.72 tons/ha. Additionally, the potential for carbon credits in the area was calculated at approximately 70.12 US$/ha. This research is crucial in understanding how specific forest areas, like special purpose forest areas Mount Bromo, can play a significant role in global environmental sustainability efforts. © (2024) Polskie Towarzystwo Inzynierii Ekologicznej (PTIE).
