Abstract

The increase of the greenhouse gas emissions concentrations causes climate change and global warming. Mount Halimun-Salak National Park (TNGHS) has high potential in mitigating CO2 gas emissions through increasing carbon stock. This study aims to estimate vegetation density using the Normalized Difference Vegetation Index (NDVI), estimate biomass and carbon stock, as well as, analyze the relationship between NDVI and vegetation diversity and carbon stock in the core zone of TNGHS. The method used was vegetation analysis, while carbon estimation used an allometric and destructive approach for the seedling and understory levels. Fifteen plots with a 15 m x 15 m area were used in this study. Based on the results of NDVI analysis, density classes were divided into three classes; class 1 (0.147-0.276), class 2 (0.276-0.321), and class 3 (0.321-0.493). The vegetation composition in the TNGHS core zone consists of 82 plant species from 53 families. The most abundant families are Euphorbiaceae, Lauraceae, Moraceae, Rubiaceae, and Urticaceae. The research location was dominated by African wood (Maesopsis eminii). The average biomass and carbon concentration based on density class obtained were 124.46 tonnes/ha and 58.50 tonnes/ha respectively. Carbon concentration had a strong correlation with Basal Area (BA) (r = 68.9%). NDVI values were positively correlated and could be used to estimate the number of species, tree density, Shannon-Wiener index, BA, and carbon concentration.
