Farahnaz Nooraii and Allahyar Kamarii

The study of the vegetative coverage of a region in order to exploit its natural sources is of great importance. Islam Abad Gharb is located in Kermanshah between 45, 24 min to 38, 30 min of the eastern longitude and 33, 36 min to 35, 15 min of the northern latitude.

The highest average temperature is 37°C in August, and the lowest average temperature is -20°C in December. The vegetative coverage of the region was determined based on the floristic method, and the biological shape of each plant was determined generally. There are 79 families, 225 genera, and 335 species. Six big families are: Brassicaceae (28 spp.), Gramineae (27 spp.), Papilionaceae (26 spp.), Apiaceae (24 spp.).
