Our work is dedicated to the evaluation and analysis of plant phytodiversity in the Ghardaïa
region (Noumérat, Metlili), by carrying out a floristic study, physical and chemical analyzes of the
soil, as well as a histological study of the tissues of certain selected plant species.
The results obtained showed that the soil in our study area is alkaline with very low salinity and
a sandy texture. It also showed that organic matter is poor and humidity is low. As well as the total
and active limestone content varies from one station to another.
The inventory that we carried out made it possible to cite a list composed of (25) species divided
into (15) families, noting that the biological type Therophyte is very widespread in the two stations.
