Soil-Vegetation Relations in Some Stations of the Kabylia Region (North Algeria)

Abstract

In order to characterize the soil-vegetation relationship in Kabylia, a qualitative  inventory of plant species was carried out in the stations of Sidi Ali Bounab,  Redjaouna and Mizrana (Tizi-Ouzou) during the spring season 2022 as well as  physico-chemical analyzes of the soil (texture, total limestone CaCO3, pH, electrical  conductivity as well as organic matter). The inventory of the flora collected made it  possible to draw up a systematic list of 54 species, of which 26 species are listed at the  level of the Redjaouna station, which is the more diversified, 23 species at the station of  Sidi Ali Bounab and only 15 species at the station of Mizrana. The latter belong to 25  botanical families, 22 orders, 4 classes (Liliopsida, Equidopsida, Magnoliopsida and  Flicopsida), and 5 divisions of the kingdom Planteae. The Fabaceae family dominates in  the Redjaouna and Sidi Ali Bounab stations, so much said that at the Mizrana station  it is the Asteraceae family that dominates. The analysis of the quality of the soils by  determining their physical and chemical properties reveals that it is favorable to the  installation and the diversification of the flora thanks to their loamy-sandy texture rich  in organic matter and their neutral pH as well as their electrical conductivity, which is  confirmed by the ecological analysis (equitability which tends towards 1) as well as  statistical analysis by ACP and CAH.
