Outline of Final Research Achievements |
In order to investigate the carbon balance of northern forest ecosystems in succession, long-term field experiments have been conducted in two differently disturbed forest ecosystems in Hokkaido, Japan: a naturally re-growing ex-larch forest after sever disturbance due to windthrow (Tomakomai) and a newly opened larch forest (Teshio). The experiments include vegetation survey, soil assessment and CO2 flux measurement by the eddy covariance and chamber techniques. In Tomakomai, annual net ecosystem CO2 exchange (NEE) had approached to zero (carbon neutral) until the 7th year after disturbance, though NEE remained positive (a carbon source) after that. In Teshio, however, the young larch forest became carbon neutral in 7 years. The difference between the two forests suggests that undergrowth vegetation and coarse woody debris plays important roles in NEE.
