The Eastern Desert of Egypt occupies 21% (c. 223000 km2) of the total area of Egypt. From the early beginnings of the last century, this desert attracted scientists, especially botanists, to study its flora, ecology and vegetation. This study (between Latitudes 30 00 N and 24 00 N) included an up-to-date checklist of its flora, quantitative analysis of its vegetation, patterns of species distribution, and a proposed phytogeographical map based on GIS analysis techniques of 500 geo-referenced sites as a preliminary step towards a general vegetation map. Classification of the vegetation yielded...

The present study deals with the floristic analysis, vegetation composition and its relation to environmental variables in the Sallum area along the Mediterranean coastal land of Egypt. It is included in the semi-desert vegetation zone with an attenuated desert climate. The recorded taxa were classified according to the life-form spectrum and chorological affinities in the study area. Stratified random sampling method was employed. Five main geomorphologic units can be distinguished in the study area from the coast in the north to the fringes of the Diffa plateau in the south. A total of 219...

The Nile Delta comprises about 63% of Egypt's most fertile land. The present flora and vegetation of water plants growing in water channels of the Nile Delta were studied through four main sectors covering its whole area. Distribution maps of some species were presented in different categories of species distribution. The severe human activities contributed largely in the disappearance of many hydrophytes. The numerical analysis of the vegetation revealed the identification of 17 vegetation groups in the different sectors. The relationship between water and its macrophytic vegetation was...
