Using of Atrush forest as study site, to quantity the forest structure, environmental services and economic returns from the forest, located in the northern part of the Kaliqeyamat mountain range and the eastern part of the heights of the kaneMazi, while it is bordered by the western part of the center of Sub-District Atrush and the southern part is bordered by the Sheikhan District (Ain Sofni), which is within latitude (36°49'), (36°53'), south and longitude (43°17'), (43°27') north and at a height ranging from (669-1017) m, above sea level. The total area of forest (1415) km², and content more the trees of (Pinus brutia), (Pinus pinea), (Quercus ajelops), (Quercus infectoria), (Platanus orientalis) and (Ficus carica) as well as shrubs (Crataegus saligna), (Junipours occidentalis), (Salix babylonica) and (Prunus amygdalus), species grown naturally, the pine species most common type of coverage of these species is estimated at approximately (27.58%). Assessing the forest structure provides a picture of current extent and condition of Atrush forest. The data collected for forest sent to the United States Forest Service (USFS) to utilized in the i-tree Eco-program(http://www.epa.gov/airquality/benmap/index.htm). The result of this study indicated that carbon storage with in tree species were varying. In addition to that only seven have stored (20.51) tons of carbon, all other tree species had less than the amount. Understanding the species grown in the site, number of per hectare and fast-growing species provides the information needed for management and utilization of Atrush forest.
