フィリピンの二次林で2012年から2024年の樹木インベントリデータを用い、炭素蓄積量と経済的価値を評価。蓄積量は202.4 Mg C/haで老齢林に匹敵し、年間2.53 Mg C/haの吸収速度は老齢林の約9倍。炭素クレジット価格に基づく経済価値は2012年の4,798ドルから2024年には7,220ドルに増加。地域の気候変動緩和戦略における二次林の重要性を示す。
English
This study evaluates carbon stocks and economic value in a Philippine secondary forest using tree inventory data from 2012, 2016, and 2024. The forest stored 202.4 Mg C/ha, comparable to old-growth forests, with a sequestration rate of 2.53 Mg C/ha/year, about nine times faster. Economic value of carbon stock rose from USD 4,798 in 2012 to USD 7,220 in 2024, highlighting the site's role in climate mitigation.

📄 Abstract（原文）
Tropical forests play a critical role in climate mitigation, yet long-term data on their carbon dynamics remain scarce, particularly in the Philippines. This study examines forest structure and carbon sequestration in a 1-hectare permanent plot established in a secondary forest on Mt. Nacolod, Southern Leyte, Philippines using 2012, 2016, and 2024 tree inventory data. The study aimed to (1) assess biomass and carbon storage trends, and (2) estimate the economic value of carbon. The secondary forest stored 202.4 Mg C/ha, comparable to reported values of old-growth forests in the Philippines. Its sequestration rate of 2.53 Mg C/ha/year is approximately nine times faster than old-growth forests and exceeds regional dipterocarp regrowth rates. Although sequestration slowed post-2016, the site remained a robust carbon sink. The estimated economic value of the stand’s carbon stock increased from USD 4,798 in 2012 to USD 7,220 in 2024, while carbon sequestered over the 12 years was valued at USD 1,076 under prevailing carbon credit prices. Key findings underscore the dominance of Dipterocarpaceae and the site’s high carbon sequestration capacity, emphasizing its critical role in regional climate mitigation strategies. Continuous monitoring reinforces its value as a long-term carbon sink, providing a benchmark for conservation and climate policy for tropical forests in the region.
