“…This species is able to grow on a variety of substrates from open sand to cemented sand (see Danin, 1983;TielboK rger, 1997;Bornkamm et al, 1998 for the Sinai and Nizzana regions; Bornkamm & Kehl, 1990 for the Western Desert of Egypt). Artemisia monosperma grows on both mobile and partly stabilized sands (Danin, 1983(Danin, , 1991 and is sometimes used as a sand binder (Koller et al, 1964).…”

“…They were also clearly separated along the first two axes of DCA, forming two major divisions along the inner city-surrounding deserts gradient. Some of these groups were recorded in other surrounding deserts of urban environments such as Calligonum polygonoides-Centropodia forsskaolii-Pulicaria undulata group that inhabits landscape vegetation outside Bahariya Oasis (Abd El-Ghani 1981) and Faiyum region (Abd El-Ghani 1985); Suaeda vermiculata group, Asphodelus aestivus-Deverra tortuosa-Gymnocarpos decandrus-Thymelaea hirsuta group lives in the western Mediterranean region (Bornkamm and Kehl 1990;Shaltout and El-Ghareeb 1992;Shaltout et al 1994); Hyoscyamus muticusAerva javanica group around the urbanized areas of Feiran Oasis (Abd El-Ghani 1998); and the Alhagi graecorum group in the outskirts of the Nile Delta region (Shaltout and Sharaf El-Din 1988;Shaltout and El-Sheikh 2002). The lower number of both species and communities in the inner town has been documented in other studies (Kunick 1974;Sundik-Wójcikowska 1987;Pyšek and Pyšek 1988;Kowarik 1990).…”

Information on the urban flora and vegetation in the industrial new cities in Egypt are insufficient and far from complete. For this reason, this study was undertaken as the first attempt to fill this gap of knowledge. For two successive years (2004 and 2005), a reconnaissance survey was conducted in four new industrial cities: 6th October, El-Sadat, Burg El-Arab and 10th Ramadan; aiming at: (1) recognizing the floristic composition and vegetation structure of each of the studied cities; (2) identifying the main urban habitats dominating the studied cities; (3) comparing the vegetation of the urban habitats at the boundaries of each city, where desert soil merges gradually with the agricultural land, with that at its centre (purely agricultural land); and (4) analyzing, quantitatively, the vegetation groups (plant communities) that characterize the urban habitats. A total of 189 permanent stands in the four cities were selected to represent the apparent variation in the different habitats. These stands were distributed as follows: 49 in 6th October, 37 in El-Sadat, 45 in Burg El-Arab, and 58 in 10th Ramadan. Altogether, 305 species of the vascular plants constituted the main synanthropic flora and the total number of species varied from 171 in Burg El-Arab, 157 in 10th Ramadan, 144 in Sadat and 132 to 6th October. The largest families that formed the main bulk of the recorded flora were Gramineae, Compositae, Leguminosae, followed by Euphorbiaceae, Chenopodiaceae, Cruciferae, Cyperaceae, Umbelliferae and Solanaceae. Five main urban habitats (from inner city toward outskirts) were distinguished: lawns, home gardens, public gardens, waste lands and desert outskirts. The most species-rich habitat was the waste lands (172 species), while the total number of species varied from 104 in the lawns and 113 home gardens, to 123 in the desert and 133 in the public gardens. Generally, the recorded synanthropic flora within the five main urban habitats can be classified into: (1) cultivated plant species that included ornamentals, hedges, shade plants, fodder plants, vegetables and fruits; (2) canal banks, salinized areas and wetland plants; (3) xerophytic plants of the outskirting desert; and (4) weeds of arable Urban Ecosyst (2011) 14:585-616

“…It may depend on simple qualitative techniques such as the Braun-Blanquet table sorting method (Braun-Blanquet, 1939;Guinochet, 1951;Lemée, 1953;Leredde, 1957;Bornkamm & Kehl, 1990;Kaabèche & Gharzouli, 1993Peinado et al, 1995;Quézel et al, 1995;Abd El-Ghani, 1996) or be based on floristic list assemblages related to discrete habitat types (Kassas & Imam, 1954;Kassas & Girgis, 1965) with an emphasis on phytogeographical plant distribution (Barry & Celles, 1973) and geobotanical studies . More complex numerical, quantitative methods include cluster analysis, two-way indicator species analysis (TWINSPAN) and correspondence analysis (Noy-Meir et al, 1970;Ward et al, 1993;El-Demerdash et al, 1995;Cowlishaw & Davies, 1997;Abd El-Ghani, 1998).…”
