Vegetative Enrichment of watersheds is one of the important objectives along with long term policies of the state for natural resources. Therefore, afforestation development needs the participation of people. Multipurpose tree planting helps to conserve soil and water and can be a suitable policy to enhance the participation of people. In order to determine the best species, 5 genotypes of almonds and a wild pistachio genotype were selected during the nursery phase and were planted as un-irrigated condition afforestation, on eastern, western, and southern aspects using randomized complete block design. Variables including mortality, collar diameter, seedling height and crown diameter were studied. Results showed that planting of two almonds genotypes (3 and 6) on western aspects considering their higher survival rate and growth attributes is recommended. Concerning the height survival rate and growth and the possibility of providing partial irrigation during summer periods, planting on southern aspects could also be recommended.
