YOGYAKARTA – Wai Apu Watershed is one of the watersheds on Buru Island, Maluku, which has an important role for local and regional economy. Recent development indicates this watershed has experienced some problems, which can threaten its important role in local regional economy. This is assumed to have occurred due to forest land degradation
This study succeeded in getting several important findings about the patterns and processes of forest degradation, which are new and never disclosed by previous researchers. The findings of the pattern and process are mostly development of the theory of transformation characterized by loss of land area that was developed by Forman (1995), which in theory development is classified as application theory. Therefore, the findings of process and pattern in theory development can be classified as, at least, preposition theory, which is under the theory of changes in land transformation as its application theory. "The disclosure of the spatial pattern findings in this research refers to the spatial pattern based on the peculiarities of physical symptoms distribution on forest land cover in a watershed," said the man born in Ambon on May 3, 1969.
