Biological recovery the steppe of Hammada scoparia after enclosure in the region of Naama (Algeria)

Abstract

This work was being carried out in the steppe of remth (Hammada scoparia) in Oranian part of the Saharan Atlas (Tiout - south of Naama). The H. scoparia of Saharan group occupies the foothills south of the Saharan Atlas and glazes and hamadas of the northern part of the Sahara where it seems to find its optimum development. The objective of the study is the floristic and ecological characterisation of the steppe vegetation groups of H. scoparia after 4 years of enclosure grazing (Eg). For the past three decades, steppe of H. scoparia were completely overwhelmed, both in their structure and their operation by increasing the herd and the continued use of natural pastures using animal load significantly higher than the production potential of course, which is reflected by the reduction of their capacity for natural regeneration.
