Abstract

The main object of the authors is to present the plant community of Argania spinosa (L.) Skeels in Algeria. The distribution area of this forest tree in the district of Tindouf (Algeria) is identified for the first time. Using phytosociological method adapted to plant community of arid and Saharan land, this study describes three new syntaxa: Faidherbio albidae—Arganietum spinosae, Periploco angustifoliae—Rhoetum tripartitae and Acacio-Arganion spinosae. The Argania community is submitted to important damages by most populations which explain the regression of its current distribution area.

Résumé

Après avoir défini le contexte écologique de la hamada, les auteurs identifient l'aire de répartition de l'arganeraie d'Algérie et précisent sa structure et son écologie. Par la méthode phytosociologique adaptée au contexte aride, ils mettent en évidence trois syntaxons nouveaux:Faidherbio albidae—Arganietum spinosae, Periploco angustifoliae—Rhoetum tripartitae et Acacio-Arganion spinosae. Du fait de la richesse floristique qui lui est associée, l'arganeraie est soumise à une pression élevée de la part des populations riveraines, ce qui explique la régression et la fragmentation de son aire de répartition actuelle.
