Floristic studies, life forms and chorology of plants in Kouh-payeh area, Isfahan Province, Iran

The Kouh-payeh with an area of ۳۰۰۰ km۲ is located at ۷۰ km east of Isfahan on the edge of central Kavir at longitude ۵۲° ۲۶ʹE and latitude ۳۲° ۴۳ʹN. In this study, the floristic richness, life form, geographical distribution and conservation status were assessed. All plant species were collected from Kouh-payeh area during ۲۰۱۴-۲۰۱۶. The collected species were identified, then life forms and chorology of each species were estimated. By examining a total of ۲۰۰ collected plant species, ۳۸ families and ۱۳۷ genera were found. The dominant life forms were mainly identified as therophytes (۴۵%) and hemicryptophytes (۳۴%). Based on chorotype information, an Irano-Touranian distribution (۶۰%) was generally observed in this area. Other chorotypes such as Irano-Touranian/Saharo-Sindian (۶%) and Irano-Touranian/ Euro-Siberian (۶%) were present in lower quantities. Among the identified species, ۴۳ endemic species were also recognized. In terms of conservation status, there were Low Risk (۷۷%), Vulnerable (۱۵%) and Data Deficient (۸%) needed some conservation policies. This study was performed for the first time in this area.
