Presentation of Diversity, Life Forms, and Chorology of Plant Species in Galehdar Watershed (Fars Province, Iran)

Aims Floristic survey of an area is a useful tool for identifying the biodiversity, particularly endemic, resistant, and endangered species. In the current study, plant species were classified to describe the flora of Galehdar watershed in Southern Fars Province. Materials & Methods The environmental data including climate, geology, and topography characteristics were obtained from Iran Meteorological Organization (IMO), Geological Survey & Mineral Explorations of Iran (GSI), and National Cartographic Center (NCC), respectively. The specimens of the study area were collected, identified, and classified according to Raunkiaer’s method and life-form class. Findings The flora of study area includes 164 species belonging to 129 genera and 55 families, which most frequent species belong to Asteraceae (25 species), Papilionaceae (21 species), and Poaceae (11 species). Conclusion The chorological studies indicated that 57.9%, 12.8%, and 29.3% of species belong to Irano-Turanian, Sahara-Seindian, and Irano-Turanian, Sahara-Seindian zone, respectively.
