カメルーン東部の半落葉樹林において、林床植生（草本、低木、リター、細根）の炭素蓄積量を推定した。4つのプール全体で11.92 ± 2.15 tC/haを貯蔵し、その47%は細根による。炭素蓄積量は直径・高さ階級に応じて釣鐘型分布を示した。REDD+プログラムの最適化や生態系の気候変動耐性向上のために、林床の炭素計上を見直す重要性を指摘する。
English
This study estimates carbon stocks of understory components (herbaceous plants, understory woody species, litter, and fine roots) in semi-deciduous forests of eastern Cameroon. The total understory carbon stock is 11.92 ± 2.15 tC/ha, with fine roots contributing 47%. Carbon stocks across diameter and height classes show a bell-shaped distribution. The findings highlight the need to reconsider the role of understory in carbon accounting for REDD+ programs and climate resilience.

📄 Abstract（原文）
In the tropical forests of the Congo Basin, the understory constitutes a forest stratum whose components are generally neglected in studies related to forest carbon storage, despite their contribution to climate change mitigation. The objective of this study is to estimate the carbon stocks of understory components (herbaceous plants, understory woody species, litter, and fine roots) in semi-deciduous forests of eastern Cameroon. Carbon stock estimation was carried out using a destructive sampling approach. Data on woody species with a diameter ≤10 cm were collected in 14 randomised plots of 20 m × 20 m (400 m²). Data on woody species with a diameter ≤4.99 cm, herbaceous plants, litter, and fine roots were collected in subplots of 10 m×10 m, 1 m×1 m, 0.5 m×0.5 m, and 0.2 m×0.2 m, respectively. Diameter and height of woody species were measured. The understory, composed of the four carbon pools mentioned above, stores 11.92 ± 2.15 tC/ha, of which 47% is contributed by fine roots, 26% by woody species, 25% by litter, and 2% by herbaceous plants. A significant difference was found among carbon stocks across the different pools considered. Carbon stocks across diameter and height classes followed a bell-shaped distribution, with peaks in the 2.5–7.5 cm diameter classes and the [4–8 m] height classes. Given these substantial quantities, it is essential to reconsider the role of the understory in carbon accounting, particularly to optimise REDD+ programs and enhance the resilience of Cameroonian forest ecosystems to climate change.
