Our work is devoted to the assessment of the plant biodiversity of the three selected resorts of the Ghardaïa region (Oued M’Zab). The floristic inventory carried out at the selected resorts allowed to identify 19 plant species and 13 families during the sampling period, the most common species are: Rhantherium adpressum, Peganum harmala and Tamarix gallica. This biodiversity varies between the three sites, we divided each station into 3 surveys. In the first station Oued M'zab (Dhaye Bendhahoua) we found 11 species and 05 species in the second station (BOUNOURA) and 11 speeds in the resort (EL ATTEUF), the collection varies by species, and the species that has the highest collection rate is: Tamarix gallica
