ABSTRACT

The objective of this work is to examine three wadis for edaphic factors and their impact on plant communities (Wadi Hagoul, Wadi El-Rashrash, and Wadi Araba) in the northern part of the Eastern Desert. There was a total of 92 plant species found in this research, including 35 annuals, 2 biennials, and 55 perennials, from 77 genera and 27 families. The dominant taxa and majority of the flora in the region under study include the Asteraceae, Boraginaceae, Fabaceae, Poaceae, Chenopodiaceae, and Zygophyllaceae families. The therophytes make up over 40% of all species, with chamaephytes coming in as a close second at 31%. According to a phytochorological analysis of the examined flora, 77.17% of the species reported are Saharo-Sindian taxa. Using the importance value (out of 200) of 92 plant species, this work was able to identify four distinct vegetation types. The most common plants in the region were found to include Haloxylon salicornicum, Zilla spinosa, Ochardenus baccatus, and Zygophyllum coccinum. Soil physical topography, soil salinity, and anthropogenic activities are main factors in determining plant distribution in the Northern Eastern Desert.
