“…Application of TWINSPAN classification technique on the sampled stands in the present study resulted in 8 vegetation groups: 4 represented the polluted site, 2 for the non-polluted site and other 2 in both sites. The most dominant species were S. spinosum and J. phoenicea; this coincided with the study of Shaltout et al (2014), who recorded S. spinosum and J. phoenicea as dominant species in the polluted areas in this region. They also reported that the polluted areas were more diverse than the non-polluted ones, while the present study indicated that the vegetation groups of non-polluted sites were more diverse than that of the polluted ones, which coincided with the studies of Hegazy et al (2011) andAl-Sodany et al (2003) at Al-Gabal Al-Akhdr.…”

“…In the present study, concentrations of the heavy metals in the soil and waste water samples from the polluted sites were higher than those from the non-polluted sites; and all above the standard levels of Syrian Standard (0.01, 0.2, 0.1, 0.2 ug ml -1 for Cd, Cu, Cr and Ni, respectively). In the same region, this finding coincided with that of Shaltout et al (2014) who reported that the concentration of Cd and Cr were higher in the polluted areas than in the un-polluted ones.…”

“…It is a hot spot of plant diversity that confines about 50% of the endemic plant species in Libya (Qaiser and El-Gadi 1984). Few studies were carried out on its ecology (Gimingham and Walton 1954;Drar, 1963;Boulos 1972Boulos , 1997Le Houerou 1997Al-Sodany et al 2003;Hamad 2012;Hegazy et al, 2011;Abusaief and Dakhil 2013;Shaltout et al 2014).…”

The present study aims at describing and analyzing the floristic composition and vegetation types, as well as evaluating the impact of waste water pollution on the plant diversity and community structure in Al-Marj plain, North Libya. Forty-two stands, distributed among polluted and non-polluted sites, were selected seasonally for this study. A total of 156 species were recorded (92 in the polluted and 121 in the non-polluted sites). Eight vegetation groups were resulted after the application of TWINSPAN and DCA as classification and ordination techniques: four represented the polluted sites, two for the non-polluted sites and other two were mixed groups. Group II (Sarcopoterium spinosum -Pistacia lentiscus), which represents the polluted sites, had the highest values of soil moisture, salinity, sulphate, calcium and potassium; while group VI (Juniperus phoenicea -Olea europaea) inhabiting the non-polluted site, had the lowest value of organic matter, salinity and magnesium. Group VII (Foeniculum vulgare -Nicotiana glauca), representing the non-polluted site, was the most diverse, while VG III (Ricinus communis -Chrysanthemum coronarium), characterizing the polluted one, was the least. Heavy metal analysis, in both soil and waste water, indicated that the concentrations of Pb, Cd, Cr, Cu and Ni in the polluted sites were significantly higher than that in the non-polluted ones. The diagram resulting from CCA showed effectiveness of most soil variables, except carbonates, sodium, magnesium and chlorides. The impact of waste water discharge led to the emergence of new invasive species, which may severely affects the plant diversity and community structure of this hot spot of biodiversity in Libya

“…These species are: Anabasis setifera, Arthrocnemum macrostachyum, Halopeplis perfoliate, Halocnemum strobilaceum, Haloxylon persicum, Haloxylon salicornicum, Salsola baryosma, Seidlitzia rosmarinus, Suaeda fruticosa and Suaeda vermiculata . It was clear from these figures that the polluted sited were less diverged than the unpolluted sited this differed from the findings of ( Shaltout et al, 2014 ) who claimed that the polluted sites were highly diverse in their vegetation cover as compared to unpolluted sites. However, our data were in line with those of ( Al-Sodany et al, 2003 , Hegazy et al, 2011 , Shaltout et al, 2015 ) who indicated that the vegetation cover in the unpolluted sites were highly diverged as compared to the vegetation cover of the polluted sites.…”

The main objectives of this study were to determine the floristic composition of the vegetation cover and to find the effects of wastewater pollution on the plant community structure in eastern Saudi Arabia. 28 stands which were distributed among polluted and unpolluted sites, were chosen for this study. A total of 42 plant species were recorded (14 in the polluted and 28 in the unpolluted sites). The recorded plants comprised of 13 perennial plant species and 29 annual plant species. Seven vegetation communities were determined using TWINSPAN and DCA classification and ordination techniques. Three in the polluted sites, two in the unpolluted sites and the remaining two were mixed communities. The (Sarcopoterium spinosum – Pistacia len‐tiscus ) community in the polluted sites, had the highest values of soil moisture, salinity, sulphate, calcium and potassium. On the other hand, Juniperus phoenicea – Olea europaea community in the unpolluted site, had the lowest value of organic matter, salinity and magnesium. In respect of genetic diversity, the community of Foeniculum vulgare - Nicotiana glauca in the unpolluted site, was the most diverse, while Ricinus communis - Chrysanthemum coronarium in the polluted sites was the least one. Both soil and wastewater heavy metal analysis indicated that Pb, Cd, Cr, Cu and Ni concentrations in the polluted sites were significantly higher than those in the unpolluted ones. The impact of wastewater discharge led to the appearance of new invasive plant species that may significantly affect plant diversity and community structure in eastern Saudi Arabia. Finally wastewater discharge in open rangelands could adversely affect the growth of plant species in the rangelands and thus adversely affect plant community structure and diversity.

“…The application of TWINSPAN classification technique to the vegetation data produced seven groups and the application of DECORANA to the same data showed resemblances among some of these groups. Groups D, F and G were dominated by Juniperus phoenicea; this coincided with the study of Shaltout et al (2014).…”
