L’ARGANERAIE DE TINDOUF

Abstract

Hamada is the traditional golf course for goat and camel breeding extensive. These pastoral potential, associated with the operation of tree species, including talha [Acacia tortilis (Forsk.) Hayne subsp raddiana (Savi) Brenan], determine the main activities of this region. Unpublished results presented concern chorologic developments related to the distribution area of the tree native flora specific to various ecological habitats. These results helped to highlight for many tree species new stations and specify the area of distribution of some other species : the distribution of the argan tree, Argania spinosa (L.) Skeels , 1911, which is known only, at some stations in the Oued El Ma is enlarged due to the recognition of new stations located in the hamada. Our investigations led to the discovery of new stations species population usually recognized as having an area of only specific distribution in the Mediterranean region. These stations are, in fact, Mediterranean area being completely isolated in the western Algerian Sahara. Beyond its operating current as rangeland, the argan tree, in terms of a conservatory in situ world heritage floristic diversity. Its protection and management is a major issue for the use of biodiversity in the context of sustainable development.
