Abstract

This work deals with the study of the vegetation in an area completely protected from camels and an area partially exposed to camels. During they study eighteen species were recorded in the areas. Ten of these species were present inside the fence and the rest of the species were present in both areas. Vegetation analysis throughout the three studied seasons revealed that species richness and diversity were higher outside the fence with a significant difference in the first two seasons (winter and autumn) whereas it was insignificant during the third season (spring). Single linkage Euclidean distance were gathered in the studied quadrants in a homogenous matter. The results are discussed and the partial conservation of the plant life rather than complete conservation is recommended as the regular seasonal grazing throughout the three studied seasons appeared to have apositive effect on the vegetation.
