AbstractThis study was conducted during spring of 2010 at Ashawa resort of Duhok governorate to identify the value of the vegetation cover according to the qualitative characters(ash, organic matter, ether extract, crude protein, crude fibers, soluble carbohydrate, calcium, potassium and phosphorus) percentages of understory vegetation and canopy cover common between aspects surrounding Ashawa resort with two elevations, The study found that there are significant differences between species, aspects and elevations for Grasses and herbs. Lathyrus sativa was significantly superior compared with other species,the east aspect was significantly superior in (potassium, crud protein and ash) percentage, the north aspect was significantly superior in (phosphorus , calcium and carbohydrate) percentage,the first level was significantly superior in (phosphorus, potassium, crud protein and ether extract) percentage, compared with the second level. As for trees and shrubs Cotoneaster racemiflorous shrubswere significantly superiorover other species for ash, carbohydrate, potassium and phosphorus percentage while it did not recorded any significancy with Quercus aegilops for ether extract. Percentage, but Q. infectoria was significantly superiorover cotoneaster racemiflorous shrubsin crude protein percentage, There were no significantly differences between both elevations levels in ether extract., crude protein, potassium and calcium percentage, while there were significantly differences between those elevations in ash, organic matter, crude fibers, soluble carbohydrate and phosphorus percentages.
