IMPORTANCE OF ALDER FORESTS FOR BIRDS IN THE NORTH-EAST OF ALGERIA: COMPOSITION AND STRUCTURE OF BREEDING BIRDS STANDS AND THE EFFECT OF FRAGMENTATIONZentar Amina, Ziane Nadia and Benyacoub Slim
This work attempts to highlight the composition and structure of alder nesting birds in Algeria, more specifically that of El Kala, and the effect of fragmentation on these nesting birds. We carried out the avifauna surveys in each area class by the I.P.A method which will allow us to measure the richness of the alder fowl. We have specified the composition and structure of the stands of pure alder groves in the El-Kala region (various sites). We have characterized the structure of the vegetation and its various parameters: (height of the different strata, overlapping of the strata, etc.) as well as the area (fragmentation). We calculated the different stand structure parameters and performed the stand analysis.
