EFFECT OF FACE AND GROWTH STAGE IN QUANTITATIVE AND QUALITITATIVE CHARACTERISTICS OF SINJAR MOUNTIAN VEGETATION

Abstract

This study was conducted in the first half of 2002 to determine the effect of the Aspect (interface ) and growth stages in the qualitative and quantitative characteristics of the surrounding areas and within Sinjar Mountain vegetation. Sinjar mountain is located Northwest of Iraq ,within the admininstrative borders of the province Nineveh to the west of Mosul city up to 150 Km and is within northern part of the Badeat Aljazeera . The highest visible point on the mountain is located at altitude of 1460 m. above sea level ,while the lowest point is allocated at altitude of 500 m. above sea level. The quantitative and qualitative characteristics were significantly affected by the Aspect and the location within mountain . Most of the quantitative and qualitative characteristics of the vegetation grew inside mountain outperformed to their counterparts in the three interfaces ,with the superiority of of the qualitative and quantitative characteristics of the vegetation of the Northern face to their counterparts in the Southren and Western faces .The percentage of crude protein , soluble carbohydrates , ash , and ether extracts decreased ,while that of crude fibers increased in the forage of pastoral inside the mountain and the Aspects as growth progress ,
