The Eastern Desert of Egypt occupies the part of the country east of the River Nile. It extends from the latitude of Cairo at the north to the Egypt/Sudan border at the south with an area of about 224,000 km2. This desert consists mainly of high and very rugged mountains running parallel to the Red Sea coast. The mountains of this desert consist of Precambrian crystalline igneous and metamorphic rocks and constitute the basement complex of Egypt (Said, 1962). However, sedimentary rocks occur mainly at the northern (mainly limestone) and southern (mainly sandstone) fringes of the desert. The mountains in the Eastern Desert are dissected by well developed drainage systems ending either at the Red Sea or at the Nile Valley. The dissection of this desert by dense networks of valleys and ravines indicates that although the present time is a dry period, the region must have witnessed some periods of wet climate in the past (Zahran and Willis, 2009). The FAO soil map of the world shows that soils of the Eastern Desert of Egypt belong mostly to the Lithosols or soils of rocky origin (Beumont et al. 1988).
Water resources are poor and are restricted to torrent storms which occur randomly in place and time. Rainfall percolates through the gravel and sand deposits of stream (wadi) beds forming local underground reservoirs (Abu Al-Izz 1971). Water shortage, topography and poor soil conditions are the main limitations to sustain traditional agriculture, however, drought resistant vegetation or typical desert plants (Xerophytes) are observed scattered along the coastal strip and in valleys. The Eastern Desert of Egypt has harsh living conditions due to prevailing hot and dry climate. Administratively, this desert is named the Red Sea Governor...

...have low fertility due to the predominance of quartz grains. If aridity, topography and hot climatic are compiled with poor soil fertility, vegetation cover becomes rare and traditional agriculture is not suitable. However, specific vegetation, which tolerates water shortage and other environmental stresses, could grow in this region. Among the natural vegetation of the region are Acacia and Tamarix Spp. Local Bedouins depend on natural vegetation as a food and energy resource as well as for medical purposes. Their animals also depend on this natural flora for grazing. In addition, there are some local attempts for cultivation of some species depending on groundwater, such as the FAO farm (120 south of Marsa Alam). At this farm, olive and Henna are cultivated. However, water scarcity near the farm forced grazing animals to damage cultivated vegetation in this farm.
