Anzali Wetland is one of the 10 most valuable and international wetlands in the world. this wetland With an area of about 20,000 hectares is a habitat for a wide range of mammals, fish, birds, reptiles and, rodents. The study of plants species provides one of the required criteria for distinguishing a wetland area and is used in the process of ecological demarcation of the wetland. The vegetation in the water body and it’s around was studied by 42 sampling plots and its species were identified. 180 species belonging to 124 genera and 48 families were identified. The Poaceae, Asteraceae, Cyperaceae, Fabaceae, Brassicaceae and, Caryophyllaceae were the most abundant families, respectively. Classification of plants based on biological form showed that the highest biological form was related to therophytes with 43%. After that, hemicryptophytes with 18% and, geophytes with 16% had the highest ferequency, respectively. The plants in terms of geographical distribution, mainly belong to the cosmopolitan elements. 35% of species belonged to the obligate. The facultative upland with 32%, facultative wetland with 15%, facultative with 14% and Upland with 4% consisted other wetland indicator plants, respectively.
