Vegetation Analysis of Cyrene (Campus apollo) Shahat AL-Jabal AL-Akhdar, Libya.

Abstract

The present study addressed the analysis of the natural vegetation in the Cyrene (campus apollo) ShahatAL-Jabal AL-Akhdar, Libya, by using the quadrate method. The diversity of vegetation at the site was estimated using nine quadrates. The dominant plant species were determined by the Importance Value Index (IVI) and were the most dominant species; Phlomis floccosa D. (IVI, 33.78%), Geranium molle L. (IVI,18.46%), and Sarcopoterium spinosum (L.) Spach. (IVI, 17%). The spatial distribution of vegetation in the study area was also studied by taking the (IVI) of each species within each quadrat and applying it to the Classification and ordination of communities, and by entering the data of the (IVI) for 9 quadrats and applying it to a Community Analysis Package (CAP) Program for the Classification and ordination of communities, and by using a technique Two-Way Indicator Species Analysis (TWINSPAN), which includes the Dendrogram and Detrended Correspondence analysis (DCA), done classification of vegetation in the study area into two communities, that according to the similarity between the quadrats and the prevailing dominance of the species in each community. Climatic variables were also taken (rainfall, maximum and minimum temperature), a ten-year average was calculated via data obtained from the Libyan National Meteorological Center, physical and chemical analyzes of soil was also carried out.
