The Floristic Diversity of the Vegetation of the Littoral in the Area of Tlemcen (Western Algeria)

Hassiba Stambouli-Meziane and Mohamed Bouazza

This study is devoted to the analysis of the vegetation of coastal dunes in the region of Tlemcen. Resultswere obtained on these in general, including the biological and ecological. These results allowed us to individualize different phytosociological classes: The Cakiletea maritimae and Ammophiletea for cash at the beach; the Thero Brachypodietea and Quercetea ilicis in the sand dune and fixed dunes. Class Cakiletea maritimae and Ammophiletea grouped species of embryonic dunes. The Brachypodietea class includes species of sand dune. The class of Quercetea ilicis includes species of the dunes most advanced and most determined. Using phytosociological data and plant dynamics, we understand the evolution of the vegetation and its diversity.
