چکیده مقاله:

The recognition of the vegetation cover of an area is the basis of ecologic studies, also it plays an important role in the environmental life management. The mountain of Naft-chak is located on the northern slope of Alborz Mountains in the east of Guilan, and the intersection of three provinces of Guilan, Mazandaran, and Qazvin. Elevation range varies between 1500 and 3012m a.s.l. The aim of this research was to identify the plant species, determination of life forms and chorology of each taxon. For this purpose, plant specimens were collected from different parts of this area during 2017 and 2018 and the species identification was carried out using Flora of Iran and Flora Iranica then kept duplicate each species in University of Guilan herbarium (code 6242 to 6418). A total number of 176 vascular plant species belonging to 140 genera and for this purpose, plant specimens were collected from different parts of this area during 2017 and 2018. A total number of 176 vascular plant species belonging to 140 genera and 56 plant families were identified from the region. The largest plant families with the highest number of species in the region include Lamiaceae (17 species), Rosaceae (14 species), Asteraceae (13 species) and Fabaceae (10 species). The main life form area: Hemicryptophytes with 50%, Geophytes with 19 %, Phanerophytes with 18 % and Chamaephytes with 2 %.The largest proportion of the chorological elements belong to Irano-Turanian floristic region which indicates that the area is strongly influenced by Irano-Turanian floristic element.
