Wetlands are one of the most important sources of life in ecosystems, as they contribute to the development and sustainability of organisms in ecosystems by providing fresh water and other direct and indirect services. Wetlands are vulnerable ecosystem, so management and conservation of them is a vital task. Considering the importance of protecting the wetlands, this study aimed to investigate the status of Amirklayeh wetland located in Gilan province based on Carlson's Trophic State Index. Sampling was done monthly from 5 stations from April to September of 2018 and the parameters measured for assessing the trophic state of wetland were Total phosphorus (TP), Total Nitrogen (TN) and Chlorophyll a (chl-a). The results indicate that the status of Amirklayeh wetland during the research period, with the Carlson index of 41 was due to the entry of organic and inorganic materials from the drainage of sewage and runoff from the surrounding area to the wetland. Therefore, the role of management and protection of the wetland is proved by decreasing the level of access and maintaining the use of natural lands, in order to maintain the livelihood of the wetland and restore it.
