BIODIVERSITY AND PLANTS PALATABILITY IN THE DROMEDARY RANGELANDS OF THE TALH "Acacia raddiana" IN THE REGION OF TINDOUF (ALGERIA)

Abstract

So far few studies have been carried on plants palatability within dromedary rangelands.Hence, our contribution focuses mainly on the floristic richness study and classification of dromedary rangelands plants of Acacia raddiana in the region of Tindouf according to their degree of palatability. For this purpose, thirty samples were collected within variable geomorphic units, namely tributary streams and wadis. The results show that the richest rangeland in species is the wadi with superficial silting. Besides, the analysis of the biological spectrum shows an overall prevalence of the therophytes. Moreover, the analysis of the palatability spectrum shows an overall prevalence of the plants with high and average appetency. This dromedary rangelands richness in various plants, integrate a wide range of palatability reflecting the selective feeding behavior of the dromedary. Indeed, it better consumes available resources in its natural environment and contributes to biodiversity conservation.
