Abstract
Hassanlou Wetland is one of the natural attractions of West Azarbaijan Province which is registered in the list of international wetlands in the Ramsar Convention. After the construction of Hassanlou dam the depth of the wetland increased, the amount of salts decreased and as a result, the wetland became more of a lake behind the dam. The change in conditions due to the construction of the dam has caused the wetland ecosystem to undergo changes. Since Hassanlou Dam Lake has a high capacity for growing of invasive aquatic plant species, samples of plant species and water from the lake were collected to identify invasive species and also to determine the water trophy. The results of the study showed the presence of four invasive plant taxa including Stuckenia pectinata, Potamogeton perfoliatus, Cerathophyllum sp., and Najas marina. Calculations based on the Carlson trophy index indicated that the water of this lake is eutrophic. The cause of this issue can be attributed to the washing of agricultural runoff containing manure of cattle that graze around the lake. High trophy has increased the density of invasive aquatic plant species, which is considered a serious threat to lives of native plant species and fisheries. To remove these unwanted plants and control their population, it is recommended to use physical, mechanical, biological and chemical control methods. In most cases, physical and mechanical methods to cut these plants are not efficient and it is appropriate to use approved herbicides that target a specific plant.
