Flora Diversity According to an Altitudinal Gradient in Kabylia Region

Abstract

The study focuses on a floristic inventory according to an altitudinal gradientfollowing a transect that includes five stations (Yakouren, Taddart, Tirsatine, TiziRached, Oued Aissi) located equidistant from the forest of Yakouren to the SebaouValley in Greater Kabyliarandom sampling was adopted during the spring season of2015 by harvesting all the plant species encountered in a comprehensive manner,while focusing on their distribution taking into account environmental factorsincluding climate, precipitation, rainfall, temperature, altitude and the nature of thesubstrate. The collected species are sorted, identified and counted. The recorded florais divided into 5 classes (Magnoliopsida, Liliopsida, Pteridophyta, Monocotyledonsand Equisetopsida), 25 orders divided into 27 families and 65 species. It shows theapparent impact of altitude and climate.
