The holm oak figures among the most prominent forest species in Algeria. The present state of its populations, the regression of its distribution, its ecological importance and the necessity, in the current world context, to promote biodiversity conservation and sustainable ecosystem development are all reasons justifying the elaboration of an Algerian holm oak forest typology, which furthermore constitutes the preliminary step to any management strategy. The vastness of our study area permitted the analysis and evaluation at different scales of holm oak forest diversity in relation with its environmental factors. Several papers have already described the primary role of climate in the distribution of holm oak formations. This study of the climate vegetation relationship in the Algerian holm oak forests will permit an evaluation of their bioclimatic and altitudinal significance and their dynamic relations. The evaluation of different climatic parameters by a new method of automatic interpolation (neural network method) served, on the one hand, to characterize the present bioclimatic area of Algerian holm oak forests, and on the other hand, to indicate an acceptable typology of the altitudinal zonation of mountain's vegetation.
