The pastoral dry and very dry areas in the Syrian steppe are among the most fragile ecosystems vis-à-vis the human activities. Therefore, most of these ecosystems were exposed to severe degradation which led to the disappearance of many plant species.

The study, which was carried out in three Syrian protected areas in the Syrian steppe (Jabila Azman ,Ashshola and Madbaa] under three protection patterns [fallow, broadcasting and replanting] together with the control [outside the protected area], has shown the effect of the partial protection and the ground factors on biodiversity and plant structure. The areas under protection and replanting with slight slopes and graveled soils outyielded the other areas in terms of the natural renewal, qualitative richness and plant structure. However, other areas under the same protection pattern did not show the same success because these areas were located in places poor in water storage and this played a limiting role for the growth and multiplication of the plant species in the dry and very dry areas.

Keywords: Syrian steppe, plant biodiversity, partial protection, rehabilitation and ecological factors.

تعد المناطق الرعوية الجافة وشديدة الجفاف في البادية السورية من أكثر الأنظمة البيئية هشاشة حيال التعديات البشرية ,لذلك فقد تعرض الكثير منها للتدهور الشديد مما أدى إلى اختفاء العديد من أنواعها النباتية .
