Carbon Balance Monitoring in Forest Ecosystems

Fujihokuroku Site
Fujihokuroku Site (Quick plotSource data (User registration))
Fuji Hokuroku Flux Observation Site (FHK) is located in the larch forest in the foothills of Mt. Fuji in Yamanashi prefecture. We began monitoring in 2006 to understand the carbon cycle processes in forest ecosystems. We employed multiple approaches to investigate forest carbon balance, such as micrometeorological measurement, forest census, and eco-physiological approach. This site is planned to be a core platform for validating satellite-based remote sensing of forest carbon stock.

Teshio Site
The observations at Teshio experimental forest (TSE) started in 2001, and the larch forest was clear-cut and planted in 2003. We monitor and evaluate the changes in forest ecosystem structure and functions on a regional scale by applying particular techniques such as the eddy covariance method and remote sensing.

Tomakomai Site
The comprehensive field research on the carbon cycle in forest ecosystem was conducted at Tomakomai site (TMK). Unfortunately, the tower and observation system were destroyed by the strong winds during a typhoon in 2004 and the monitoring was stopped. Available datasets are from July 2000 to September 2004.
