Analyse phytosociologique des formations de matorral du massif des Béni-Snasséne (Maroc Oriental)

Abstract

Phytosociological analysis of Béni-Snassène shrubland (Morocco oriental). The study consists in defining the phytosociological units in which one line up the formings of the Béni-Snassène matorral, to specify their floristiques affinities with the groupings which their are close and their positions in the dynamic series of the region and finally to determine the climatic conditions and edaphic in which they develop. The methodology of approach used for that is known phytosociological or sigmatist. This one allowed the individualization of eight vegetable associations among which each is examined on the plans floristique, biogeographic, ecological and dynamic. These associations are arranged as follows: Classe of Quercetea ilicis with three associations integrated into the order of Pistacio-Rhamnetalia and the alliance of Asparago-Rhamnion; Classe of the Cisto-Lavanduletea with a single association belonging to the order of Halimietalia-riphaeo atlantici; Classe of the Rosmarinetea with four associations being attached to the order of Cisto mauritanici-Thymetalia munbyani.
