One of them is about 6.5 Kilometers along southern-northen geographical directions and other is about 12.5 Kilometers along western-eastern geographical direction. The most important ecological characterstics in sites under study have been determined in four parts: ecology(climate) (26 factors- use from Kriging method), soil(14 factors- To dig a profil in each site and study), phisygraphy(8 factors- slope, geographical direction and altidue study) and plant covering(percentage of conopy cover and percentage of plant composition- Random- Systematic Sampling). In order to study the similarities between places under study and Key words: Range, Environment factors, Ordination , Dendrogram
