The plant survey recorded 22 families, 42 genera and 48 species in Madar valley as well as recording 25 families, 42 genera and 52 species in Shohouh valley.

High plant repetition and high frequency percentage are found in the two valleys for Prosopis juliflora, Ziziphus spina-christi, and Acacia tortillis, while less frequency percentage was found for Ziziphus leucodermis, Maerua spp, Citrus aurantifolia and Pithecellobium dulce.

Maddar valley was found to be better than Shohouh valley in plant frequency percentage for Ziziphus spina-christi, Acacia tortillis, and Acacia ehrenbergiana.

High density and relative density were found in the sampling plots for Prosopis juliflora, Zygophyllum spp, Acacia tortillis and Acacia ehrenbergiana, while less plant density for Ziziphus leucodermis and Maerua sp was found.

There is an abundance of Ziziphus spina-christi, Acacia tortillis, Prosopis juliflora and Phoenix dactylifera in Madar valley and Shohouh valley, while there is a less abundance of Ziziphus leucodermis and Maerua spp at the two valleys .
