“…Moreover, Sheded () recorded 129 species in the basement of the Red Sea (Wadis; Gimal, Hamata and Abu‐Ghosun), while the Egyptian Protectorate Sector () recorded 140 species in Wadi Gimal protectorate including the study area. Galal () reported that the distribution of plant species differs along elevation gradients in Wadi Gimal. He found that A. tortilis subsp.…”

The present study deals with the analysis of the floristic composition and plant diversity of Wadi Gimal protectorate. Its major aim is to identify community types and environmental factors that affect their growth and distribution. These quantitative data provide rangers with knowledge that is necessary for monitoring and managing plant communities within the protected areas, as well as restoration of vegetation‐depleted habitats. Twenty‐seven stands were selected along the length of Wadi and its tributaries. Thirty‐five species were recorded in Wadi Gimal; with Poaceae as the dominant family and Phanerophytes dominating over other life forms. Saharo‐Arabians were the predominant chorological element. Six vegetation groups were recognized in Wadi Gimal. Zilla spinosa (VG C) which inhabited the Wadi bed had the highest species richness, species turnover, relative evenness and relative concentration of dominance. Capparis sinaica (VG A) which inhabited the mountain slope had the lowest species richness, relative evenness and relative concentration of dominance, while Salvadora persica group had the lowest species turnover. Phoenix dactylifera–Hyphaene thebaica (VG F) which dominated the deltaic part of Wadi, had the highest salinity; whilst Acacia ehrenbergiana (VG E) which dominated the upper‐stream part of the Wadi had the lowest value of salinity.

“…In arid areas, shrubby plants tend to be most abundant than trees because plants expand horizontally rather than vertically in order to provide safe microsites (Galal, 2011). Furthermore, horizontal expansion tends to increase soil capital resources such as water, soil organic matter, nutrients, etc.…”

“…The predominance of young plants confirmed the high capacity of regeneration of the dominant species and the low distribution of adult plants indicates their highly exploitation. The predominance of young over the mature plants in a system have been attributed to stable population (Galal, 2011). Moreover, high abundant of juveniles is essential for a population to maintain itself (Lykke, 1998;Okiror et al, 2012).…”

The present study investigates the importance of harvesting regimes and natural disturbances on the diversity, the population structure and the regeneration trends of the woody plant species of Sahelian rangelands and their implication for sustainable browsing management. Woody plants data was collected in 42 plots established in the interval of 500 m, along transects distant of 500 m, in the direction South-west and North-east of the study area. In each plot, height and diameter at breast height of each individual mature tree and shrub (diameter < 4 cm), and the number of seedlings (diameter > 4 cm) were recorded. A total number of 21 plants species were recorded, with low values of the Shannon-Weaver (H') index and the evenness of Piélou (E) indicating very low diversity of rangelands. Analysis of size classes distribution of diameters and heights of the whole vegetation and the three dominants species revealed high density of juveniles, relating to stable populations. The juvenile plants represented more than 80 of the vegetation with diameters and heights respectively lower than 6 cm and 2.5 m, indicating shrubby vegetation. Combretum micranthum, Guiera senegalensis and Combretum nigricans which have the highest values of IVI, have also the greatest rates of seedling and vegetative propagation densities. Stable populations with strong capacity of regeneration under harsh area and high human pression such as logging and grazing can be related ecological success. Management practices that promote plantations or managing natural regeneration of such species can facilitate fast secondary succession towards desirable condition.

“…Shrubs and trees of desert communities could thus be considered as keystone species, on which many other ecosystem processes depend (e.g. herbivory) (Galal, 2011). In Egypt, the desert vegetation is by far the most important and characteristic type of natural plant life.…”
