Pendugaan Kerapatan Vegetasi Menggunakan NDVI dan Cadangan Karbon di Zona Inti Taman Nasional Gunung Halimun Salak

Abstract

Increasing concentrations of greenhouse gas emissions causes climate change and global warming. Gunung Halimun Salak National Park (GHSNP) potentially mitigate CO2 emissions change by increasing carbon stocks. This study aimed to estimate vegetation density using the Normalized Difference Vegetation Index (NDVI), biomass and aboveground carbon stocks, as well as to analyze the relationship of NDVI with vegetation diversity and carbon stocks in the core zone of GHSNP. The method used was vegetation analysis and carbon estimation using allometric and destructive testing for seedling and understory levels. The total plots were 15 (a plot size of 50 × 50 m). NDVI was categorized into three classes, specifically class 1 (0,147 – 0,276), class 2 (0,276 – 0,321), and class 3 (0,321 – 0,493). The core zone of GHSNP consists of 82 plant species from 53 families. The most families found were Euphorbiaceae, Lauraceae, Moraceae, Rubiaceae, and Urticaceae. The research location was dominated by african wood (Maesopsis eminii). The average biomass and carbon concentrations based on density class were 124,46 ton/ha dan 58,50 ton/ha, respectively. Carbon concentration strongly correlated with basal area (r = 68,9%). NDVI values had a positive correlation and can be used to estimate species abundance, tree density, Shannon-Wiener index, LBDS, and carbon concentration.
