ABSTRACT
The biodiversity of Egypt can be summarized as general features of the four main geomorphologic units, namely: Western desert, Nile land, Eastern desert, and Sinai Peninsula. The plant diversity in Nile system shows that Nile delta is the richest, while Nile in Fayium depression has the lowest diversity. Among the characteristic hydrophytes of the Nile Delta: Elodea canadensis, Pistia stratiotes, Lemna minor and Ranunculus rionii. Egyptian flora contains a low number of endemic species amounted 61 species and no endemic families most of the endemic species are grouped to the following families: Lamiaceae, Liliaceae, Scrophulariaceae, and Asteraceae. The Egyptian wetlands in Red Sea, Mediterranean Sea and Lake Nasser are important habitats for the bird migrations in which during autumn a huge number of white storks, common cranes and white pelicans are traced annually.
