This study was carried out in order to compare the stablishment of 7 needle leaved and broad leaved species and their resistance to drought in semiarid site in Talar river basins (Grabsar region of Masandaran province), since 1369. Experimental design was completely randomized blocks with 3 replications and 7 treatments (Pious brutia, Cupressus arizonica, Cupressus sempervirens var. I lorizontalis, Tetraclinis articulata, Rohinia pseudacacia, Ailanthus altissima, Celtis austra/is). Survival, mean collar diameter, mean hight and qualitative parameters were measured and analized after 5 years. Analize of variance show that differences between treatments are significant so that Cup. Setup. Far, Horizontalis, Celtis austra/i.s and Cup. crizonico were successful, Pious brutia was promissing spicces and the other species were not successful.
