Ghamisheleh forests located at 36 km of northern Marivan, Kurdistan province, were quantitatively analyzed, on the basis of IVI (Importance Value Index ), a total of two forest types, Quercus libani Olive. on north, north west and north east and , Quercus brantii Lindl. on south, south east, south west and east, aspects. Spatial patterns of species distribution were characterised by clumped ( contagious ) distribution in all forest types. The mean total tree basal area ( 25.4, 22.9 m2/ha) were exhibited by Quercus libani and Quercus brantii types,respectively and the total density (494.1,429.7 tree/ha) were determined by Quercus libani and Quercus brantii types,respectively. Maximum IVI among all the aspects was shown by Quercus libani ( 238.1). Minimum similarity coefficient was observed between north, north east, north west and south, south east, south west, east.
