Abstract: In this study, Senna holosericea and Prosopis juliflora are found to be the leading dominant species because of their wide ecological tolerance along the Super Highway near Sohrab Ghoth in Karachi. Abutilon indicum, Fagonia indica and Blepharis sindica were also found as leading species in other stands, but their importance values were rather low. Heavy metals such as Cu, Zn and Pb in stands dominated by P. juliflora and S. holosericea showed their broad range of occurrence, particularly for P. juliflora. One of the stands in which B. sindica was dominant, highest concentration of Cu (305 μgg-1) and the lowest levels of Zn (35 μgg-1) and Pb (15 μgg-1) have been reported. Considerable higher values of Cu, Zn and Pb metals have been recorded in some of the stands, where Suaeda fruticosa and Salsola baryosma was associated with P. juliflora.
