Arasbaran region is located in the north west of Iran and north of the east Azarbayjan province and most of these forests are seen in four areas of Kalibarchay, Ilgenechay,Hajilerchay and Selenchay. Result showed that 107 species belonge to 74 genera and 36 families of vascular plants are found. which Dicotyledons with 32 families were the richest group. In terms of abundance, Monocotyledons with 4 families and Gymnospermes with 2 families were in the second and third place respectively and one family with one genus and one specie was also from vascular cryptogam. Families of fabaceae with 18 species, Asteraceae with 13 species. Rosaceae with 8 species, Lamiaceae  with 6 species and Poaceae with 6 species were as the most important plant families in term of plant species that included a total of 47.63 % of the total species. Life forms of region plants contains of Hemicryptophytes with 42 species Phanerophytes with 26 species, Therophytes with 25 species, Cryptophytes with 11 species and Chamephytes with 3 species ,which among them Rosaceae had the greatest number of Phanerophytes, peas greatest number of Therophytes, chicory greatest number of Hemicryptophytes, mint largest number of Chamephytes and grasses has the highest number of Cryptophytes. According to classifications were made on the basis of Rannkier system and calculation were made Hemicryptophytes with having 39.25 percent share of the total number of species constitute the dominant life forms of the region which respectively after them Phanerophytes with 24.29% and and Therophytes with 23.36% and Cryptophytes with 10.28% and Chamephytes with 2.80% are in the next orders results of determination of corotype plants of region showed that plants with the Geographical distribution of the Irano-Turanian with 34.5%, Euro- Siberian with 30.5% are the most important group of the Region
