Carbon sequestration and stockpiling in Indonesian community forests become a pressing issue in the context of efforts to mitigate climate change and Indonesia’s contribution to the Sustainable Development Goals. This investigation aimed to determine the carbon stocks at various forest structures within the Lemo Nakai (CF) community forest. The CF encompasses an area between 3°25‘59,588” - 3 27‘57,982” in altitude and 102°19‘25,108” - 102°22‘23,416” in length. The research was conducted between February and July of 2022. The estimated biomass in dense, medium, and sparse forest structures was 601 tons ha-1, 443 tons ha-1, and 241 tons ha-1, respectively, with carbon reservoirs of 276 tons ha-1, 204 tons ha-1, and 111 tons ha-1, respectively. In addition, the estimated CO2eq absorption in dense, medium, and sparse forest structures were 1,013 tons ha-1, 748 tons ha-1, and 406 tons ha-1, respectively.
