| Outline of Final Research Achievements |
Most forest ecosystems act as substantial sink for CO2 from the atmosphere. Hence, there are many studies on carbon dynamics in forest ecosystem to quantify carbon pool and fluxes for precise estimation of contributions of forest ecosystems to climate change mitigation. In general, old-growth forests are traditionally viewed to be in carbon equilibrium. However, contrary to more than 40 years of conventional wisdom, a new analysis (Luyssaert et al. 2008) suggests that old growth forests are usually "carbon sinks". But the question is not yet decided. To fill the gap of knowledge on the contributions of the old-growth forests to climate change mitigation, we conducted a research program for evaluation of carbon dynamics in cool-temperate old-growth beech forests in Japan. Our results showed that carbon dynamics in the old-growth forest was affected by stand structure, and suggested that the carbon sink ability would be altered depend on the unique stand structure.
