The local distribution pattern of H. arbona aggrcgative; the number of individual of tm is smaller than pole, sapling and seedling. There was some poaching for H. arbona's trees andcaused the number of individual of tree level become small. 6 ind./ha; compared with pole which had 86 ind.iha, sapling 468 i n d h ot 3664 ind./ha for seedling.
