Dinarkooh Protected Area (DPA), which is located south of the city of Abdanan, Ilam Province, Iran, has not been investigated in terms of vegetation. The impact of climate change with increasing temperature and decreasing rainfall in DPA has been extremely sensible in recent years, especially in 2017. Plant species composition can play an important role in influencing the vegetation community from rainfall changes. This research investigates flora, life forms and chorology of DPA at 1300-1900m above sea level. Life forms were determined by Raunkiaer method. Overall, 142 plant Species belonging to 105 genera and 29 families were identified. Asteraceae (30 Species), Papilionaceae (21 Species), Poaceae (14 Species) and Lamiacea and Caryophyllacea (each 8 Species) constituted 21.12, 14.79, 9.85 and 5.63 percent of the flora, respectively. Totally, 87 % of the species belonged to Irano-Tourani region. Therophytes (45%) and hemicryptophytes (34 %) were more dominant life forms in the study area.
