The use of components of biological diversity for development in various fields (industry, medicine, agriculture and others) as well as ignorance of the potential make existing inventory of flora and fauna heritage is the first step intersectoral approach initiated since the signing in June 1994 in Rio, by Algeria, Convention on Biological Diversity.
The Forest ecosystems Dréat it’s a part of Algeria, it's located north of the province of M'sila.and it's very diversified by the middle forest and its rich flora. The flora inventory revealed the existence of nearly 442 species of which more than 248 genera belonging to several families have medicinal properties. As in most regions of Algeria, the inhabitants of Dréat employ some of these species in traditional medicine (Quercus ilex L., Eryngium ilicifolium Lamk, Scandix pecten-Veneris L, Asteriscus pygmaeus Coss and Kral, Calendula aegyptica Desf., Carlina involucrata ssp corymbosa Q and S, Centaurea furfuracea Coss and Kral, Cirsium echinatum (Desf) DC ...).
The study area contains a very rich and important flora with 72 endemic species, 142 rare species, rare and quite rare and 156 medicinal species.
A significant number of spontaneous species in the study area have potential value in terms of medicine, these species are the subject of mining in particular substances essential oils (such as: Foeniculum vulgare (Miller) Gaertn, Artemisia absinthium L, Cynara cardunculus L, Matricaria chamomilla L, Taraxacum officinale Weber ex Wiggers, Scorzonera undulata Batt, Borago officinalis L, Capsella bursa pastoris L).
The implementation processes of cultures of these species, in place of the anarchic collection, can improve the income of local people while ensuring the conservation of plant diversity. The culture of these economic interest and marketing plants, undoubtedly increase the income of people in the region Dreat.
