Description
Acacia raddiana, in Arabic talha, belongs to the legume family and the mimosaceae subfamily. The talha is a tree that can reach 7 to 13 m in height, with a diameter of 40 to 50 cm.
It plays an important role in the lives of nomads. In the dry season, it compensates for the deficiency of the grass, with animals grazing on its leaves and consuming its pods.
Nomads extract the gum which they use as a pharmaceutical product to treat lung infections. Tannins are extracted from its bark. Its wood is used for heating.
Formerly, the Sahara was covered with vast areas of Acacia raddiana, thus creating a link between the pistachio tree of the Atlas and the jujube tree in northern Algeria and the acacia of the African savannahs.
The abusive exploitation and progressive drying of the Sahara led to a considerable reduction in the surface area of the talha, which is currently only maintained in relict stations in southern Oran and the mountainous massifs of the central Sahara.
It is a species very resistant to drought, maintaining itself in conditions of extreme aridity, thanks to its taprooting capable of fetching water at depth. This characteristic makes talha a species to be retained for the reforestation of desert regions.
Studies on this species are being carried out in Algeria by the National Center for Research on Arid Zones (CNRZA).
