A Study of Floristic, Life Form, and Chorology of Plants in the West of Maharloo watershed, Fars Province

In this study, the flora, life form and chorology of plants in the west of Maharloo watershed located in Fars province, with an area of 293.8 square kilometers, were studied by sampling by linear method and linear transect during 2019 and 2020. This region is located at an altitude of 1800 to 2050 meters above sea level. Based on the results, 154 plant species belonging to 34 families and 108 genera were identified in this region, of which 30 species were endemic to Iran and the Iranian plateau and 5 species were endemic to Fars province. The families Asteraceae with 29 species (18.83%), Papilionaceae with 20 species (12.98%) and Poaceae with 18 species (11.68%) are in the first to third ranks, respectively. Therophytes with 59 species (38.32%) were the most abundant life form. The highest chorology of plants with 82 species (53.25%) is related to the Iranian-Turanian region. It is suggested that with proper management will be provided opportunities for reproduction and conservation of plant species in this region.
