Research site was determine using purposive sampling method with the area measuring of 60x200 meter, subdivided into 10 observation areas. Vegetation analysis was carried out by applying a square method or plots with certain sizes which were categorized into tree (20x20 meter) pole (10x10 meter), sapling (5x5 meter), seedling (2x2 meter), and ground cover (1x1 meter). The result of this study were consisting of 38 species of tree, 56 species of pole, 44 species of sapling , 24 species of seedling, and 19 species of ground cover.
