| Outline of Final Research Achievements |
To evaluate carbon budget of the beech forest by micrometeorological method with high accuracy, we held CO2 profile observations under the forest canopy in addition to CO2 flux observations on the canopy. CO2 storage under the canopy in winter was significantly large and contributed 10% of annual carbon budget.
Besides, we held consecutive photographing by time-lapse camera and soil temperatures measurements for phenology and snowmelt observations. In the beech dominant plot, snowmelt was earlier than other plots and leaf-emergence was also earlier than other species. Survival rates for beech seedlings and saplings decreased significantly as snowmelt duration increased.
