The high abundance of aquatic plants and sedimentation are the main problems in Anzali Wetland. In this study the identification and biomass of dominated aquatic plants was investigated in western part of Anzali Wetland. Among four submerged macrophytes, the Ceratophyllum demersum and Myriophyllum spicatum had the highest distribution and abundance. The biomass average were 743.8 ± 536.5 and 292 ± 311 gr dry weight m-2 in summer 2017 and winter 2018, respectively. The biomass seasonal change was more in eastern rather than western of studied area. Azolla filiculoides had a high abundant and distributed in marginal area during summer while it was completely and incredibly disappeared until winter around Anzali Wetland. Among marginal floating macrophytes, Nelumbo nucifera and Hydrocotyle vulgaris were highly distributed with 240.6 ± 70.4 and 338.8 ± 142 gr dry weight m-2 respectively. The Wetland Macropphyte Index value was nearly similar around study area and was about 1. The annually dead of macrophytes in winter can increase the eutrophication trend in Anzali Wetland. Then, it's necessary to remove the aquatic plants in Anzali Wetland to preserve of its ecological and economical values.
