Investigation of physiognomic and floristic characteristic of mountain meadows in the south of Alborz Mountain (Parvar region)

Study of vegetation composition is necessary for indication of the plants existence and condition. The vegetation identification has a crucial importance because of their fundamental role in the bioscience and the knowledge and utilization of natural environment. Accordingly, the current study has been done to consider the distribution and diversity of meadows in Iran and their importance on forage production. In this regard, plants were collected and classified base on life form, bioform and their Lifespan in order to study the floristic of meadows. Our survey was carried out in Parvar area which showed that this area had 54 species, 45 genus and 22 families. Poaceae with 18 species and Asteraceae with 6 species had the highest abundance in the region. The main vegetation compositions of meadows were included a variety of grasses and grass-like form. Furthermore, Hemi-cryptophytes were the main Bio-form in this area that demonstrated the cool and moderate climate.
