Floristic Composition, Diversity Species and Vegetation Analysis of Benghazi Plain Region (Daryanah to Tokra) – Eastern Libya

الملخص

The Floristic Analysis, life forms and chorology were conduct in Benghazi plain regions: Daryanah, Tansulukh, Al-Mabni, Brace and Tokra. The recorded of 138 species (64.49% annuals and 35.50% perennials) belonging to 32 families. In addition, results showed the absolute dominance of therophytes (66.68%), as well as the total chorological analysis of the served flora presented revealed that 82 species 65% of the total recorded species are mono-regional in being native to Mediterranean chorotype (77 species). The results were based on the fact that the Tokra area is more diverse because of its proximity to the Green Mountain, of the depth of its soil and the abundance of rainfall, and that drought and human activities such as agricultural expansion and urban sprawl negatively affect the vegetation, so the vegetation must be preserved through the establishment of reserves and the restoration of  environmental  balance.
