ABSTRACT: This study aims to develop a method for assessing above ground bimass and carbon sequestration using data obtained from unmanned aerial vehicle (UAV) imagery. The research focuses on analyzing above ground biomass and estimating carbon storage by examining the correlation between carbon sequestration and vegetation indices through regression analysis. Field survey data revealed a total of 336 trees and 22 plant species. The total above ground biomass in the study area was found to be 86.214 tons, with a corresponding carbon sequestration of 40.520 tons of carbon. Vegetation index (VI) analysis employed three modeling approaches—NDVI_FC, SAVI_FC, and MSAVI2_FC—using an area block method. The estimated carbon sequestration values were 6.90388, 6.90388, and 6.83419 tons, respectively. Using the grid block method, the carbon sequestration values derived from NDVI_FC, SAVI_FC, and MSAVI2_FC were 32.47310, 32.48533, and 34.17078 tons, respectively. This study demonstrates the effectiveness of UAV imagery in estimating carbon sequestration, which can be effectively applied in natural resource management and environmental planning.
