This book addressing the vegetation characteristics of WAFR flora, including trees, understory layer and the soil physical and chemical properties. It examined slope orientation effects on the vegetation composition, diversity, structure, density of the plant communities, tree canopy cover and tree girth/diameter at breast height (DBH) as well as soil physical and chemical properties. It was assumed/ hypothesised that the differences in vegetation characteristics are related to differences in resources available in addition to the fact that (SFSA) receives many times the amount of solar radiation that received by (NFSA). The results showed that slope aspects had significant effects on the composition, structure, and biomass, density of the plant communities developing in both slope aspects and soil physical and chemical properties
