Le Cèdred el 'Atlas (Cedrus atlantica Manetti) est une essence forestièree ndémique des montagnes d'Afrique du Nord.I Ic onstitue l'essence noble des forêts de l'Algérie et du Maroc(M'Hirit, 1994). Il forme actuellement sept blocs distincts, dont quatred ans les montagnes marocaines et trois dans les montagnes algériennes (l'Atlas tellien, l'Ouarsenis et les Aurès). En plus de ses caractéristiques sylvicoles (bois d'oeuvre, huile aromatique) et écologiques (résistance au feu, rusticité et tolérance aux différents stress) qui font de lui une essence de base pour la reconstitution et la revalorisation du patrimoine forestier,l eC èdred el 'Atlasp ar les différentes formations qu'il constitue, offred es habitats favorables pour une faune très diversifiée.

This work aims to compile the birds breeding in the cedar forest of Aurès and to study the “Bird – Habitat” relationships. The data was collected using the progressive frequency sampling method that served as the basis for the diagnosis build on an analytical approach designed around three tools (mutual information, ecological profiles, modelling). Information theory tools allowed us to identify the indicator values of species as well as the most important descriptors. Habitat modelling has been prepared for species with a high indicator value. The logistic models are shown to be well adapted to the nature of the ornithological data. They related the occurrences of the species with the dendro-ecological descriptors. The 70 surveys carried out enabled us to identify 32 bird species. The ecological analysis revealed the most active descriptors and the species with high indicator value. The best-fitting models are those of Short-toed Treecreeper with positive effect of dead wood, density of trees and variability of distances between trees, and European Robin with negative effect of anthropization and general coverage, and positive effect of crown parametres. We conclude that promoting forest structural complexity by diversifying management regimes will be key to maintain avian biodiversity in cedar forests.
