Phytosociology of wadi system west of Qusseir province

Abstract

Twelve wadis proliferate in the area surveyed drain this part of the Red Sea mountains into the Sea at Qusseir province. Phytosociological study of these wadis is based on the analysis of 55 stands using the Zuarich‐Montpellier technique. The vegetation survey revealed the prevailance of perennials in this area. Two distinct community types are recognized in the stands studied in the investigated wadis, each of which seems to have its own ecological characteristics especially concerning the water factor. The community type dominated by Capparis decidua and Tamarix nilotica covering the deltaic areas and the end parts of the wadis traversing the inland basement complex country. Some members of this community type are halophytic plants. The other community type dominated by Pulicaria undulata and Pulicaria crispa was found inhabiting most of the wadis courses especially the high localities. Members of this community type reflect the prevailing xerophytic conditions. Elements of the alliance Zygophyllaeion coccini previously recognized in other wadis of this desert are well represented in these wadis. Within the area surveyed, the individuals of most species covered in this study exhibit a wide range of variation in size and vitality. These differences are related mainly to differences in water resources.

Vegetation analysis, phenological patterns and chorological affinities in Wadi Qena, Eastern Desert, Egypt

“…Salama & Fayed () recognized Z. spinosa and S. imbricata in one community in Wadi Barramiya. Zilla spinosa has also been recorded in the wadi system west of Qusseir province, Wadi El‐Matuli, Wadi Gimal, Wadi Qassab, Wadi Kherit and Wadi El‐Ghuza (Salama & El‐Naggar, ; El‐Sharkawi, Fayed & Salama, , , ; El‐Sharkawi, Salama & Fayed, , ), respectively. The 54 collected species in the present study is higher than that recorded (39 species) in the previous studies, which may be attributed to the dry period during 2009 and a heavy rainfall in January 2010.…”

Variations in Vegetation Structure, Species Dominance and Plant Communities in South of the Eastern Desert-Egypt

“…In Egypt, like in the other arid lands, the desert vegetation is characterized by openness and is composed of a permanent framework of perennials, the interspaces of which may be occupied by ephemerals and their duration depends on the irregular rainfall and soil thickness (Zahran and Willis, 2009). The vegetation composition and plants distribution covering the Egyptian Eastern Desert and Red Sea coast such as in the northern inland part Fossati et al, 1998), in Wadi Allaqi (Sheded et al, 2012), in Wadi Degla (Hegazy et al, 2012), in Wadi Gimal (Galal and Fahmy, 2011;Gomaa, 2012), in Wadi Natash (Suzan et al, 2013) and in central Eastern Desert (Abd El-Ghani et al, 2013a;Salama and El-Naggar, 1991;Salama and Fayed, 1990;Salama et al, 2012Salama et al, , 2013 have been studied.…”

A Study on Vegetation Diversity Along Cairo – Ismailia Desert Road, Egypt

“…In the Eastern Desert, the natural vegetation occurs in the main stream of the wadis as well as on the slopes of the mountains that receive rainfall with mean annual up to 60 mm Willis, 2009 andEl-Amier, 2014). The plant life in the Eastern desert was studied botanically by different researchers (Kassas, 1953a(Kassas, , 1953b(Kassas, , 1954Kassas and El-Abyad, 1962;Girgis, 1964, 1965;Fayed, 1989, 1990;Salama and El-Naggar, 1991;Abd El-Ghani, 1998;Boulos, 2008 andSalama, et al, 2013). Most of the previous studies dealt with the different ecological aspects, with less attention to the floristic features of this desert.…”
