| Outline of Final Research Achievements |
Industrial plantation rapidly expands in various tropical areas. Therefore, plantation monitoring is now an urgent issue. Satellite remote sensing is very useful for monitoring forest conditions. Especially microwave satellite remote sensing technique enables to observe the Earth’s surface without being affected by cloud which covers tropical area throughout the year. In this study, we analyzed L-band microwave synthetic aperture radar (SAR) data for plantation monitoring. We identified forest degradation occurred within the part of forest compartment by means of comparing SAR data with on-site survey data. Furthermore, we show the possibility of the quantitative evaluation of forest structure complexity and quantity of understory vegetation using microwave satellite data. Based on the findings, our future work is to utilized microwave satellite data for spatial evaluation of biodiversity which strongly correlates with forest complexity.
