| Outline of Final Research Achievements |
In northern Thailand, there are two types of teak plantation; those of FIO have been well-managed as commercially-based industrial forests while those of RFD have been left without any management for the main purpose of ecosystem conservation. This study investigated those plantations in terms of GIS mapping, soil environments, forest metrological environments, and tree ecophysiology in order to clarify the environmental factors and mechanisms that affect teak growth performance and to assess the effectiveness to rehabilitate degraded forest. As the main finding, the most important factor which determinates teak growth in this area is regarded to be soil moisture availability and amount during the early rainy season. In order to attain both teak production and forest conservation, new zonation of forests to production forest and conservation forest with high biodiversity will be required taking into consideration soil moisture retention and supply capacity.
