- Abstract
The arid and semi-arid regions of the extreme west of Algeria, as in the study area, represent in the current state, a transitional environment between the steppes and matorrals. Our objective being the floristic and ecological characterization of the vegetation of the study area and thus to seize the dynamic aspects and the evolution of the groupings. The method of Transects is used to know easily and quickly the effect of the modifications of the environment (exposure, slope, ground...) on the distribution of the vegetation in other words to determine to understand the dynamics. The results obtained are likely to provide us with valuable information as well on the evolution as on the situation of the degraded zones. Indeed, steppe and presteppe vegetation occupy important surfaces, but also in a more limited way almost everywhere in the region. The pre-steppe vegetation with xeric determinism has remained essentially confined to the altitudes, with an extremely low development and where the grassy and therophytic cover clearly dominates. Despite the intensity of anthropogenic degradation, the irreversibility stage is not yet achieved; since the advent of a rainy period leads to a more or less rapid recovery of the vegetation.
