Struktur Tegakan dan Sebaran Jenis Ramin dan Meranti di Hutan Rawa Gambut (Studi Kasus PT. Diamond Raya Timber dan PT. Riau Andalan Pulp And Paper, Provinsi Riau)
Abstract
Ramin and meranti are recognized as main tree species in peat swamp forest. This study was aimed to determine stand structure and distribution of ramin and meranti, and to determine the existence and growth indicators of ramin and meranti in their natural habitat. The research was conducted in June 2010 at IUPHHK PT Diamond Raya Timber and PT Riau Andalan Pulp and Paper, Riau Province. Stem diameter of trees 10 cm up was recorded using vegetation analysis method in sampling plots size of 100 m x 100 m which was divided into sub plot of 25 m x 25 m. The result shows that the total number of tree species is 26 species at IUPHHK PT Diamond Raya Timber and 45 species at PT Riau Andalan Pulp and Paper. However, the abundance of ramin and meranti species is less than 12% from the tree total number growing in the peat swamp forest either at PT Diamond Raya Timber or PT Riau Andalan Pulp and Paper. Both ramin and meranti grow in the uniform pattern in which the distribution patterns of their stand structure did not follow usual form.
