Abstract

Oshtorankooh protected area is located in the east of Lorestan. The aim of the present study was to investigate vegetation, biological forms, and geographical distribution pattern of plant species in the area. A total of 730 species of vascular plants belonging to 77 families and 382 plant genera were identified. Asteraceae (116 species), Fabaceae (81 species), Lamiaceae (74 species), Poaceae (63 species), Brassicaceae (56 species), Apiaceae (46 species), and Rosaceae (24 species) had the highest number of species and the largest share of species richness in the study area. Hemicryptophyt with 264 species (36.16%) and Therophyt with 251 (34.38 %) were the most frequent biological form of the area. The plant species of the Irano-Turanian region with 330 species (45.2%) had the highest distribution and the dominant species of the region. Of the total species identified in the Oshtrankooh protected area, 107 were Iranian Endemics. In order to preserve valuable species of this region, it is necessary to implement severe conservation plannings.
