A Comparative Study of Vegetation in Madar and Shohouh Valleys in Hadhramout

Abstract

Bee rangeland plants are the basic sector of successful bee projects because they possess a verified range
of species whose flowers contains nectar and pollen grains used in bee feeding. The study is conducted in
Madar valley and Shohouh valley in Hadhramout valley. The objectives of the study are to compare bee
plant species scattered in the two valleys . The survey of plants was carried out in February and March
2017 using systematic sampling plots collection. 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 .
