Abstract. Marimpan LS, Khan K, Pramatana F, Purnama MME, Sinaga PS, Sipayung RH. 2026. Carbon stock estimation of ​​Kelimutu National Park, East Nusa Tenggara, Indonesia. Asian J For 10 (1): r100116. https://doi.org/10.13057/asianjfor/r100116. The increasing rate of global warming each year occurs alongside the decline in environmental quality, deforestation, and land desertification. Forests are major carbon reservoirs and play a critical role in the global carbon cycle, as well as being capable of reducing the impact of global warming. The Kelimutu National Park, East Nusa Tenggara, Indonesia, which contains the tri-colored lakes, must be preserved to maintain stability in CO2 absorption. The aim of this study was to estimate biomass and carbon stock in forest area of the Kelimutu National Park Forest. This study used a non-destructive vegetation sampling method to estimate biomass including using employing allometric equation to calculate vegetation biomass, while necromass and litter used equations developed by the National Standardization Agency. Furthermore, to determine the potential for CO2 absorption from the atmosphere, a conversion factor of 3.67 is applied. The study results show that carbon storage in vegetation is 104.33 Mg ha-1, in litter is 7.32 Mg ha-1 and in necromass, which includes dead tree and deadwood, amounts to 20.49 and 46.49 Mg ha-1, respectively, resulted total carbon stock of 178.63 Mg ha-1. The CO2 absorption potential is 601.97 Mg CO2 ha-1. This research underscores the importance of preserving Kelimutu National Park not only as a geological heritage but also as an asset in global carbon regulation.
