Abstract:
In the northern and the eastern slopes of Sabalan mountains which has a semi-aria climate. There were several pools، and wetlands and the study of the flora in these areas is important. Identification of plants provide useful guidelines for environmental and ecological management. In this study، flora، life form and chorology the species were studied and introduced. During vegetation growth، from 2008 to 2009 we collected and identified plant species in the region، and floristic list was provided. The results showed that totally، there were 216 plant species that belonged to 128 genera and 36 families in the studied area. The flora of these regions included 216 plant species that belonged to 128 genera and 36 families. Poaceae family including 25 genera and 46 species، Astraceae family with 11 genera and 19 species، Fabaceae family with 9 genera and 18 species and Brassicaceae family with 12 genera and 15 species، had the highest number of species. Also according to the classification Raunkiaer system (Raunkiaer، 1934) there were 22%. Therophytes، 30% Cryptophytes، 46% Hemicryptophytes، and 2% Chamaephytes. From view point of plant chorology، were formed in: 44. 44% Pluriregional، 20. 83% Europa-Siberian، Irano-Turanian and Mediterranean، 15. 74% Europa-Siberian، Irano-Turanian، 3. 7% Europa-Siberian، 2. 32% Irano-Turanian and Mediterranean، 5. 56% Indemic for Iran and 7. 41% of species were not identified. Considering that the region climate affected by Siberian، Hyrkaniane and Mediterranean climate therefore the most vegetative elements in this study region belonged to Europa-Siberian and Europa-Siberian، Irano-Turanian، respectively.
