日本語
エチオピア北部タボタットのツツジ科帯森林で、胸高直径1.5cm以上の樹木を測定し、汎熱帯・地域別アロメトリー式で地上・地下バイオマスと炭素を推定した。総バイオマスは約54.78t/ha、炭素は27.29t/ha、CO2換算で最大100.53t/haの貯留能を示す。Erica arboreaが炭素蓄積の大半を占め、REDD+のベースライン整備に資する。土壌炭素や枯死木など未測定プールの評価が今後の課題とされる。
English
This study measured woody plants (DBH ≥1.5 cm) in the Tabotat Ericaceous Belt forest, northern Ethiopia, estimating above- and belowground biomass and carbon using pan-tropical and local allometric equations. Total biomass reached ~54.78 t/ha and carbon ~27.29 t/ha, equivalent to up to 100.53 tCO2e/ha, with Erica arborea dominating stocks. It provides a baseline carbon inventory relevant to REDD+ monitoring, while noting unmeasured pools such as soil organic carbon, deadwood, and litter.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業のScope 3や森林クレジット調達の文脈では、途上国森林の炭素インベントリ整備はオフセット・自然資本評価の基礎情報となる。ただしSSBJ・有報開示への直接の示唆は限定的。
In the global GX context
Adds a site-level carbon inventory to the global stock of REDD+/AFOLU baselines, supporting MRV for nature-based credits and land-sector accounting under voluntary carbon markets. It illustrates the data gaps (soil carbon, deadwood, litter) that still limit comparability with IPCC-guideline reporting.

📄 Abstract（原文）
Forests play a critical role in the natural global carbon cycle by capturing carbon dioxide from the atmosphere via photosynthesis. Therefore, carbon inventories serve as a baseline for assessing carbon capital supplied by REDD+ programs. However, Ethiopia does not have carbon inventories for every forest patch to monitor and enhance the carbon sequestration potential of the different forests. This study aimed to estimate the biomass carbon stock in woody plants of Tabotat Ericaceous Belt forests for climate change mitigation. Trees with diameter at breast height ≥ 1.5 cm were measured for their diameter and height. Both above- and below-ground biomass and carbon were estimated using pan-tropical and local allometric equations. The results were analyzed using PAST software, version 4.03, and Microsoft Excel, version 2016. The accumulation of forest biomass, including above- and below-ground, is approximately 54.78 tons per hectare, and the carbon content is 27.29 tons per hectare. The Tabotat Ericaceous Belt forest can store up to 100.53 metric tons of carbon dioxide equivalent per hectare from the atmosphere, significantly contributing to regional climate change regulation. Erica arborea accumulated 40.14 ton per hectare of total biomass (above- and belowground biomass) and 20.07 of total carbon (above- and belowground carbon) in their bodies than other tree or shrub species. Rosa abyssinica Lindely stores 0.01 ton per hectare total biomass (above- and belowground biomass) of biomass and 0.005 total carbon (above- and belowground carbon). The future research should assess the unmeasured carbon pools, such as soil organic carbon, deadwood, and litter.
