FLORISTIC DIVERSITY OF WITHANIA FRUTESCENS (SOLANACEAE) IN THE STATIONS OF ZENÂTA AIRPORT AND SEBAA CHIOUKH IN THE REGION OF TLEMCEN (WESTERN ALGERIA)

Abstract

Vegetation cover is one of the main components of natural environments. Vegetation plays a fundamental role in the structure and functioning of ecosystems, of which it constitutes an expression of biological potential. The forest ecosystem of western Algeria, and more precisely that of the Tlemcen region, which is part of the Mediterranean domain, has suffered for several years a continuous regression, clearly visible and sometimes irreversible, and most often due to a combined action of climatic, ecological and anthropogenic factors. Faced with the gravity of this ecological situation in the region, the need for an action plan to preserve biodiversity is imperative in order to measure and quantify the degradation of biological resources. But such a plan can only see the light of day if the knowledge and management of the flora by the ecologists is mastered, with the major concern for the dynamics of the vegetation, because the vegetation of the Tlemcen region presents a good example. Study of plant diversity and an interesting synthesis of the natural dynamics of ecosystems, from the coast to the steppes.
