DIVERSITE FLORISTIQUE ET STRUCTURE DEMOGRAPHIQUE DES PEUPLEMENTS DE QUERCUS SUBER L. DE LA FORET D’OULED BECHIH (SOUK AHRAS)

Abstract

The present study aims to characterize the floristic diversity and the demographic structure of the woody groups of cork oak (Quercus suber L.) of the forest of Ouled Bechih (Souk Ahras). Floristic and dendrometric data were collected in four plots of 900 m² and regeneration was assessed. The flora inventory has identified 25 species belonging to 25 genera and 18 families. The Asteraceae family is the most common (20%), followed by the Fabaceae, Oleaceae and Rosaceae (8%). The other families include species that are very poorly represented (4%). The diameter and height structures show a concentration of adult individuals in all the stands. In the perspective of rehabilitation and sustainable management of forest ecosystems, this study provides additional information on the current state of cork oak stands in the Ouled Bechih forest.
