Abstract

The present study was carried out to evaluate the floral diversity of Touggourt area in Sahara Septentrional Algerian. Foursampling sites purposely selected for this study.Using the subjective sampling method using and minimum area field technique.The results revealeda floristic richness of 49 species belonging to 44 genera and 22 botanical families grouped into two monocotyledon and dicotyledon classes, divided into 26 perennials and 23 ephemeral. The families best represented are Amaranthaceae (18.36%) followed equally by Asteraceae and Poaceae (14.28%). The distribution of species remains heterogeneous from one station to another and from one biotope to another. The biological spectrum of species harvested with a predominance of Therophytes (36,71%) and Chamyphetes (30,61%), a predominance that denotes a semiarid and arid climate. Biogeographically, saharo-Indian binding species are best presented with (42.85%) followed by endemic species (22.44%) indicating that Touggourt is a predominantly Saharo-Indian and endemic phytogeographic aera.the preservation of this short-term exceptional biodiversity requires the urgent establishment of scientific studies and appropriate safeguards.
