Taiwan study finds soil holds most forest carbon reserves

Taiwan Forestry Research Institute (TFRI) research reveals that soil holds the largest carbon reserves in Taiwan’s forests, accounting for about 45% of total ecosystem storage, surpassing tree trunks. A study in Nantou’s Renlun Forest Road found deep soil under Taiwanese China fir has the highest carbon concentration among artificial forests, outperforming Chamaecyparis formosensis and Taiwania cryptomerioides, with differences of 10-20 metric tons per hectare. Selecting optimal tree species for afforestation could boost Taiwan’s carbon sink competitiveness, while long-term management, including non-commercial thinning, sustains sequestration despite typhoons and heavy rains.
