Pistacia atlantica is a very important species in Iran. It is a multiple potpuse species people who lives near it's habitat consider it as a holly tree and also it is economicaly valuable to them, they use and sell the fruit, the gum and the seed oil. The goal of this project is to convince these people that by taking care of these trees and improving them they can have more benefit. To reach this goal, two different sit were chosen for investigating different characteristic of the trees and area and also the improvement activity. These sit were in Kordestan province one in near Marivan city in an area called Dezly and one near Baneh city in an area called Armardeh. Geographical characteristics of these area is Dezly Longitude: 603812-604877 Latitude: 3916861-3917638 Armardeh Longitude: 570887-572930 Latitude: 3973102-3974836 728 trees were investigated in these two sits. For each tree phenology, yield, gender, health, age class, height, latitude and longitude were distinguished. For improvement 4 trees were in 5 different age classes were chosen. These trees were fertilized. The results showed that number of male trees were significantly more thane female trees in Armardeh. Number of main trunk was higher in Dezly, so that 81% of trees in Armardeh had one mane trunk. The diameters of the trunks were higher in Armardeh. 73.7% of trees in Armardeh were in good health. Trees in Armardeh beard more fruit than Dezly. It seems that the owners of Armardeh site have taken a god care of the trees but in Dezly because the owners change each year, they do not take care of the trees very well.
