Abstract

The present study aims to characterize the ligneous vegetation of the forest massif of Chettaba in terms of its floristic composition and its structure. The data was collected by means of floristic surveys, measuring the diameter at 1.30 m for trees and by counting individuals with a diameter < 5 cm in four plots of 30m x 30m (900 m2). Diversity indices were calculated based on specific frequencies. The dendrometric parameters and calculated diversity indices vary from one plot to another. Thus, the density varies from 444 to 1067 individuals/ha, the basal area from 5.30 to 18.12 m²/ha, the average height from 3.82 to 6.47m, the total volume is from 13.14 to 79.44 m3/ha. The Shannon index varies from 0.38 to 0.99 bits and that of Pielou from 0.29 to 0.55 bits, thus reflecting a generally low woody diversity. Holm oak with a high IVI value is considered a main species. These data complete and refine the knowledge of this forest phytodiversity, an essential basis for the development of management plans for sustainable management.
