Considering appropriate adaptability of different wild species of pistacia in different arid and semi-arid environment of the country as well as its high value from the point of view of rezin and other chemical production, oil, and pharmacological consumption of their seeds, founding their habitats in the different areas of Markazi province (as a sub-project of the national project under the title of The study of pistacia distribution and related influencing factors in Iran) seems to be important. In this project first of all, the basic informaton including topographical,soil, climate, geologyl, and landuse map of Nazar Kardeh mountain in Saveh Town ship with 1/50000 scale were prepared and digitized.In order to study the phenological characteristics of the species.The parameters, such as the number of trees in the samples, trees height, trees width diameters, the time of flowering, the time of leaf appearance, the amount of seeds and its color, ... were recorded in sampling areas. After establishing the DEM of the areas, aspect and slope map were also produced using dfdx and dfdy filter using Ilwis Academic program package. On the basis of this investigation the following results were obtained. The distribution limits are located between 1080 to 1293 above sea level.The density of trees are 30 – 50 individuals per ha.The average hight of the trees is 3.27 m, and the maximum hight is 5 m.The average height of the tree trunk is about 1.18m.The average tree crown height is 2.10 m.The mean tree trunk diameter (diameter at breast hight ) is 7.3 cm.The average hight of the large and small crown are in order 2.1 m and 3.16m
