| Outline of Final Research Achievements |
In forests, distances between individual canopy trees are large and it is unclear the degree of interaction between individuals for light competition. In the present study, we evaluated the degree of interaction, which was defined as the fraction of light that penetrated through the foliage of neighbor individuals, using two methods. The results suggest that the degree of interaction in a forest is about 0.5, indicating there is a significant interaction in light interception between neighbors. This value is useful for modeling of game in light competition in forests, contributing to projection of CO2 absorption rate in future forests.
