本研究は、インドネシアのケリムツ国立公園における森林のバイオマスと炭素蓄積量を推定した。非破壊的な植生サンプリング法とアロメトリー式を用いて、植生、リター、ネクロマス（枯死木）の炭素量を算出し、総炭素蓄積量は178.63 Mg ha-1、CO2吸収ポテンシャルは601.97 Mg CO2 ha-1と推定された。この結果は、同公園が地球規模の炭素調整において重要な役割を果たすことを示している。

English

This study estimates biomass and carbon stock in Kelimutu National Park, Indonesia. Using non-destructive sampling and allometric equations, it finds total carbon stock of 178.63 Mg ha-1 in vegetation, litter, and necromass, with a CO2 absorption potential of 601.97 Mg CO2 ha-1. The findings highlight the park's role as a carbon reservoir and its importance for global carbon regulation.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

インドネシアの国立公園における炭素蓄積データは、日本が推進する国際的な森林保全やREDD+の取り組みにも関連するが、国内のGX政策（SSBJや有報など）への直接的な示唆は限られる。

In the global GX context

This paper provides empirical carbon stock data from an Indonesian national park, contributing to the global understanding of forest carbon dynamics. It can inform nature-based solutions and carbon offset methodologies relevant for international climate disclosure frameworks like TCFD and ISSB that include land-use emissions.

👥 読者別の含意

🔬研究者:Provides detailed carbon stock estimates for a unique forest ecosystem using standard allometric equations.

🏢実務担当者:Can be used for baseline carbon accounting in REDD+ projects or forest carbon credits.

🏛政策担当者:Offers evidence for the importance of protecting national parks as carbon sinks in national climate strategies.

📄 Abstract（原文）

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.
