The purpose of this study was to determine the diversity of wintering water birds and waders in Alagol, Almagol, Ajigol and Anzali wetlands and the impact of land use changes on the distribution of these wetlands.Materials and Methods: ETM + satellite images after atmospheric and geometrical correction were used to evaluate the changes. The NDVI index identified the overall vegetation cover of the wetlands on and out of the coast. Then, dominant plants and representative of wetland status were identified and evaluated by unsupervised classification. The diversity of water birds and waders was assessed using Total Count Method. Species diversity index, species uniformity and interspecific similarity were calculated and reported.Results: The catchment area of the studied wetland has decreased significantly during the last 10 years and the type of vegetation and area of the catchment area has increased toward nutritional state. The highest number of migratory water birds belonged to the duckweed, with an average of 65.99% of the total migratory bird population belonged to this species, especially the water feeding ducks.Conclusion: Due to the lack of legal compliance with the wetland and the increasing use of agricultural and human-made land uses, this changing and growing land use will have adverse effects on the wetland ecosystem
