Outline of Final Research Achievements

Crown shyness (CS) is a clearance between crowns of neighboring trees. CS is considered to be formed by movement and collision of crowns, which may depend on the wind speed, tree architecture and wood mechanical property. The variations of CS in natural forests are not well understood, thus we aimed to understand how CS is formed and to what extent CS depend on tree characteristics. In this study, we did the following tasks; (1) determining to what extent tree stems were deformed by wind and topography, (2) building a procedure to measure CS with UAV and (3) clarifying the links between CS and tree characteristics.
