| Summary: | The Algerian tell, especially the area of Tlemcen, has a flora and vegetation of the most remarkable in its diversity including Algeria. We are currently witnessing an abuse of this wealth by man for survival with accelerated harvesting of these resources beyond their renewal capacity and because of the strong anthropic pressure. These species are used either for timber and fuel (firewood, etc.). Either as golf course (agro-forestry-pastoral system). Climatic variations (rainfall, temperature) proved a major change process that sward. However, the dynamics of these formations can understand their current extension has been and is still under the influence of human pressure becoming stronger; mainly through voluntary clearings (fertilizer use), grazing (addition of organic matter) and fires (flammable and combustible species). It now seems necessary to develop research programs to understand the genesis of this green energy by using new technologies.
