Utilisation de l’Indice de biodiversité potentielle dans les formations de chêne faginé dans l’Aurès (nord-est de l’Algérie) : Évaluation des capacités d’accueil pour la biodiversité et promotion d’une gestion intégrative

Abstract : The hosting capacity for ordinary biodiversity of forests dominated by Portuguese oak (Quercus faginea Lam.) was assessed in the Aures by using the Index of Potential Biodiversity (IBP), used for the first time in Algerian forests. The IBP diagnostics were carried out on 12 plots covering a total area of 4 ha. The total scores obtained range between 64% and 70% of the maximum possible score, indicating a fairly high hosting capacity for animal, plant and fungal species. Very large trees and standing dead wood are among the factors receiving the highest scores, mainly due to Portuguese oak and Atlas cedar (Cedrus atlantica (Manetti ex Endl.) Carrière). The characterization of stands using the ten IBP factors makes it possible to propose management in favour of biodiversity. The IBP has proved to be relevant in this specific context of oak forests, which encourages applying such tests in other types of Algerian forests.
