To highlight the state of the vegetation cover in the Western Sahara, a study was carried out on the floristic groups of Acacia raddiana in the Tindouf region. A floristic inventory of the species where Acacia raddiana is present were carried out, and at the same time, climatic data (precipitation and temperature) were analyzed. The results of this study show the shortage of precipitation and confirm the drought that the region experiences throughout the year. The floristic study makes it possible to identify 59 species distributed within 24 families. Therophytes play a very important role in the floristic composition of the studied area.
