Résumé:
The Mostaganémois coastline, part of the Oran Sahel, is located in the semi arid, under the influence of the sea; moreover the land has varied geological and edaphic characteristics. Plant biodiversity at the level of the Mostaganémois coastline has been achieved, knowing that the vegetation is subject to constraints of anthropogenic origin following socioeconomic issues, a highly coveted area, especially strong urbanization and accelerated tourism over the past three decades.
Our objective is to contribute to the study of flora and the transformation undergone by plant communities, spatial and temporal distribution of existing plant species during a certain period.
Our methodology is based on carrying out floristic surveys following a subjective sampling.
Our samples were identified by several floras, including the new Algerian flora of Quézel and Santa 1962, 1963. We have drawn up a floristic list for the three sites, grouping the families, species genera, the stratum and the ecological distribution of the plants taxa that we have included in the table.
