Forestry and Other Land Uses (FOLU) merupakan sektor penting dalam strategi pembangunan rendah karbon dan ketahanan iklim. Kawasan konservasi Taman Nasional Gunung Halimun Salak (TNGHS) berpotensi dalam mitigasi perubahan iklim melalui peningkatan stok karbon. Penelitian ini bertujuan untuk menduga kerapatan vegetasi menggunakan Normalized Difference Vegetation Index (NDVI), menduga biomassa dan cadangan karbon, serta menganalisis hubungan NDVI dengan keanekaragaman vegetasi dan cadangan karbon di zona inti TNGHS. Metode yang digunakan yaitu analisis vegetasi dan pendugaan karbon menggunakan pendekatan alometrik dan destruktif untuk strata semai dan tumbuhan bawah. Plot yang dibangun berukuran 50 m × 50 m sebanyak 14 plot. Berdasarkan hasil analisis NDVI, kelas kerapatan terbagi menjadi kelas 1 (0,72 - 0,76) dan kelas 2 (0,77 - 0,85). Komposisi vegetasi di zona pemanfaatan TNGHS terdiri atas 36 jenis tumbuhan dari 16 famili. Famili terbanyak adalah Lauraceae, Fagaceae, dan Myrtaceae. Lokasi penelitian didominasi oleh Castanopsis acuminatissima. Rata-rata biomassa dan stok karbon yang diperoleh masing-masing sebesar 268,98 ton/ha dan 126,96 ton C/ha. Stok karbon memiliki korelasi tertinggi dengan LBDS (r = 84%). Nilai NDVI memiliki korelasi tertinggi dengan kerapatan pohon per ha. Forestry and Other Land Uses (FOLU) is an important sector in low-carbon development strategies and climate resilience. The Gunung Halimun Salak National Park (TNGHS) conservation area has the potential to mitigate climate change through increasing carbon stocks. This research aims to estimate vegetation density using the Normalized Difference Vegetation Index (NDVI), estimate biomass and carbon stocks, and analyze the relationship between NDVI and vegetation diversity and carbon stocks in the core zone of TNGHS. The methods used are vegetation analysis and carbon estimation using allometric and destructive approaches for seedling and understory strata. There were 14 established with the size 50 m × 50 m. Based on the results of NDVI analysis, density classes are divided into class 1 (0.72 - 0.76) and class 2 (0.77 - 0.85). The vegetation composition in the TNGHS core zone consists of 36 plant species from 16 families. The most abundant families are Lauraceae, Fagaceae, and Myrtaceae. The research location is dominated by Castanopsis acuminatissima. The average biomass and carbon concentrations obtained were 268.98 tonnes/ha and 126.96 tonnes C/ha respectively. Carbon concentration had the highest correlation with LBDS (r = 84%). NDVI values had the highest correlation with tree density per hectare.
