This study aimed at evaluating floristic list, life forms and chorology of plant species of Shalam protected area, which is in western Iran. This region is characterized by various physiographic conditions and oak (Quercus brantii L.) as the dominant tree species. Plant species were collected by field survey in May and June 2016. The species were identified and their chorology, growth form and life form were determined using taxonomy resources. The results showed that flora of this region includes 129 plant species, belonging to 34 families and 101 genera. The Poaceae­ (20 species), Papilionaceae (18 species), Asteraceae (15 species) and Lamiaceae (12 species) were the most frequently encountered families. The number of species were more in southern than in the north-facing slope in different elevation classes. According to Raunkiaer’s classification of life forms, therophytes and hemicryptophytes were the dominant life forms in the study area. In addition, annunal and perennial forbs dominated the growth forms of both facing aspects. In geographical distribution point of view, Irano-turanian and Irano-turanian- Mediterranean in all physiographic conditions had the highest geographical distribution.
