Investigation of Flora, Life Form, and Medicinal Species in the Central Part of Eastern Kiyar (between Dastgerd Imamzadeh and Shalamzar) in Chaharmahal and Bakhtiari Province

Carrying out scientific activities in various biological, agricultural, pharmaceutical and industrial fields in a region requires knowing and introducing the collection of plants in that region. The study of plant biodiversity in Central Zagros is important from different aspects and has been the focus of attention. In this research, the flora of a region of Eastern Kiyar including 5 villages located in Chaharmahal and Bakhtiari province was investigated. Plant specimens were collected and identified in two vegetative periods, and traits related to the biological form, belonging to the vegetative area, condition, and medicinal potential of the species were determined. The results showed that the flora of this area consisted of 269 species belonging to 181 genera and 48 genera. The most important families in terms of the number of species were Asteraceae (51 species), Fabaceae (24 species), Brassicaceae (23 species), and the largest families in terms of the number of genera were Asteraceae (27 genera), Brassicaceae, (17 genera), Poaceae (16 genera) and Lamiaceae (13 genera) respectively. The study of the frequency of vegetative forms by the Raunkiaer method in the flora of the region showed that 47% of the species were hemi-cryptophyte, 32% of the species were therophytes, 12% geophytes, 6% chamophytes and 2% phanerophytes. Also, 188 species (70%) belonged to the Iran-Turani vegetation zone. Among the species, 66 medicinal species and two species in critical conservation status were detected.
