DezRiver is one of the five most important permanent rivers of khouzestan province of Iran where there are about 15873 ha riparian groves, growing in continuous or discontinuous forms at different densities. Ten tree and shrub species were used in this experiment to increase diversity at the riparian groves of DezRiver and use them for rehabilitation and expansion program of the groves. The trail was conducted under experimental design of Randomized Complete Blocks with three replicates in 1993 at rainfed condition and in 2001. Ninety seedlings of each species were planted at each plot (3×3 m.) Survival and average of height and diameter of the species were recorded. Effects of drought and water logging period on the species performance were investigated. Six of the species (Eucalyptus camaldulensis 9616, E. microtheca, Acacia farnesiana, A. salicina, A. stenophylla and Dalbergia sisso) were the most resistant to ecological condition due to their high percentage of survival (> 75%). Acacia victoriaewas eliminated from the trail at the second year, because of its low resistant to soil and climate fragile conditions. The species E. camaldulensis 9616, Dalbergia sisso and A. salicina achieved the greatest average of height and diameter growth rate.
