Phytosociology of Matorral of the South-East Slope of Tlemcen: A Case from Western Algeria

The present work was carriedout at the level of the Matorral South-East of Tlemcen North-West Algeria, tomeet this objective 150 surveys, were conducted using the phytosociological method of Braun-Blanquet. The infiltration of Quercetea ilicis, Pistacio-Rhamnetalia alaterni, Rosmarinetea officinalis, Stellarietea mediae, and Tuberarietea guttatae, which demonstrate that ecological conditions have in fact changed, is significant in the phytosociological study of groups. The commonly used method is to harvest all plant speciesen countered and make the list of speciesona plot of minimum area 03 stations (Ain Tallout, Meurbah and Dermam).

The study is able to identify five groups using numerical classifications ascending hierarchical (CAH), which demonstrate how the ecological conditions have actually changed and caused the gradual disappearance of the vegetation cover in Quercetea ilicis, Pistacio-Rhamnetalia alaterni, Rosmarinetea officinalis, Stellarietea mediae, and Tuberarietea guttatae.
