Abstract

The authors study the syntaxonomic structure and the ecological and dynamic value of the matorrals of the Eastern Morocco, between the Algerian frontier and the chains of the Rif and the Middle Atlas. They belong to the class Ononido-Rosmarinetea in an essentially semi-arid environment and take part in various series constituted by Tetraclinis articulata, Pinus halepensis, Juniperus turbinata and Quercus rotundifolia. We thus define 32 associations or communities in connection, in littoral and sub-littoral environments, with the Cisto mauritanici-Thymetalia munbyani in which the genus Cistus, Rosmarinus, Thymus and Genista are prevailing, and in more continental environments, with the Anarrhino fruticosi-Astragaletalia armati in which Stipa tenacissima is very frequent. As for the alliancies, we describe, in the first order, respectively from the north to the south, the Ulici africani-Rosmarion tournefortii and the Staehelino macrocephalae-Genistion pseudoretamoidis, and in the second order we describe the Bupleuro aiouensis-Globularion nainii, essentially on the edges of the Eastern Middle and High Atlas. At a higher altitude, we also define or restructure various associations in connection with the Erinacetalia Quézel 1952 and that it would be advisable to refer to the alliancy Genistion pseudopilosae-Thymion comosi Benabid 1990 present on the Causses of the Middle Atlas also on the Bou Iblane, the Tichchoukt and the Ayachi.
