There are about 350000 hectares of sand dunes and sandy lands in Khuzestan. During the past 40 years, different physical, chemical and biological operations were applied to stabilize these lands and the results were statisfactory. These operations were important in view point of soil conservation, environment rehabilitation and sustainable development, but not in view points of economical and social affairs. The trail was conducted to in troduce some multipurpose forest species in rainfed condition of semi-arid parts of Khuzestan and on sand dune lands. Three species of Acacia, including A. acuminata, A. farnesiana and A. victoriae were planted in 1993 under statistical design of Complete Blocks, with three replicates, at 3H3 m. spacing and against dominant wind direction. After seven years, the data were analyzed. The results showed that there were significant differences between the species. A. farnesiana had the highest percentage of survival (62%), wherease A. victoriae achieved the maximum rate of height and diameter growth (3.87 m. and 5.3 cm, respectively).
