Evaluation of plant diversity of the steppe interface, Sahara (Case of Brezina, El-Bayadh Algeria Southwest)
Abstract
The present work was carried out at the level of the steppe region of Brezina in the Algerian South-west, the objective of this study were the assessment and the description of the state of the ground vegetation based on the plant ecology. Floristic inventory counts more than 60 taxa, divided into 21 families usually returns to the Asteraceae and Fabaceae. The passage of the steppes of Alfa to other formations as sagebrush or Spart (Lygeum spartum) possible show that ecological conditions have really changed. This change is closely related to the pressure enthropozoogenic, translates to the common development of the Therophytiques, spiny or/and toxic and Sahara species. Their dominance remains an explanatory element of this advance of the desert.
