| Outline of Final Research Achievements |
Our primary objective is to evaluate the physical and physiological impact of canopy fragmentation on canopy trees, through predicting the change in micro environment, especially wind synopsis, around canopy trees caused by the fragmentation.
We determined 3-dimensional leaf distribution of 64 canopy trees using terrestrial laser scanning method. The leaf distribution, the combination of leaf area index and the clumping structure determined the drag relations against crown with simple equation. The wind environment on canopy related to the complexity of canopy structure created by gaps. We also clarified the property of turning moment in tropical trees to use for the evaluation of wind damage risks. We could not observe clear relationship between the decline in canopy trees and the location from canopy gaps in both a seasonal forest in Vietnam and a rain forest in Malaysia.
