1 - Investigation of birds' density and species diversity of Amir-Kelayeh international wetland during a 10-year period (2007-2016), based on winter census

In present study, the density and diversity of bird species (waterbird, wader and terrestrial bird dependent to the wetland) has been studied in Amir-Kelayeh international wetland based on the semi-winter birds census data, over a 10-year statistical period. During this ten-year period, the total number of 334776 birds from 46 different birds species was recorded in this wetland. Among the studied years, the highest number of 72188 birds in 2008 and the lowest number of 1877 birds in 2015 have been counted. In terms of quality and food items, this wetland and it's around paddy fields is a good refuge for the Anatidae and Rallidae family that with 64.86 and 50.06 percent of frequency depending on their diet, have the most abundant among the identified family. The biodiversity indexes showed a relatively high amounts, but with a declining trend, and also the index of species evenness indicated a stable trend during this 10-year period in Amir-Kelayeh Wetland. Considering the decreasing trend of biodiversity indexes in Amir-Kelayeh wetland in recent years, increasing the wetland ecological conservation through the management plans such as habitat structure conservation, and illegal hunting and pollution control is recommended.

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. Manuscript profile -

Environmental Impact Assessment ensures the environmental concept of sustainable development by providing the necessary environmental information to determine the environmental friendliness of a proposed project. Mechanical harvesting of aquatic plants along with biological and reed harvesting in the whole area of West Wetland and opening the entrance of Chafrud River were the main activities that could be implemented in this project. Mechanical harvesting operations are performed with a Harvester machine and reed harvesting is done with a motor saw or manually. The most important activities of the project are mechanical harvesting (reed harvesting and immersion of aquatic plants floating with the Harvester machine), restoration and cleaning of waterways (Chafrud River), dewatering and rehabilitation of West Wetland, biological control and operation of wooden bridge and bird watching station. Environmental parameters, consequences and nature of the effect, impact time, magnitude of the effect and the scope of the effect were investigated and the positive and negative effects of the design were determined.

4 - Assessment of trophy status of wetlands in Lorestan province based on Carlson TSI index( Case study: Poldokhtar wetlands, Borujerd corridor and Tanodar Doroud wetlands)

Therefore, a suitable method should be used to determine the trophy status, or in other words, the production capacity of an ecosystem. Conventional methods for determining the amount of trophy are based on three physical, chemical and biological parameters. Lorestan province due to its unique construction has unique wetlands, including 11 Poldokhtar wetlands with an area of 142.7 hectares, Bishe Dalan wetland with 913.5 hectares and Tanodar wetland with an area of 1000 hectares. In this study, to evaluate the trophy status, sampling of phosphorus (TP), total nitrogen (TN) concentration or Carlson trophy index (TSI) was used in Poldokhtar, Bishe Dalan and Tanodar for summer and winter of 2019. Based on the annual average of Carlson index, Poldakhtar and Bishe Delan wetlands are in mild mesotrophic trophy conditions and Tanodar wetland is in the eutrophic category. In the wetlands of Lorestan province, the sediment load of suspended solids and water turbidity have been exceeded these wetlands limits and has had destructive effects on the unstable wetlands` body due to the annual entry of large amounts of sediment from the catchment, development of gardens, various recreational withdrawals in Boroujerd and Doroud, increasing the level of river water pollution caused by municipal and industrial wastewater, also, wastes from city and rural recreation centers and wastes from point sources of pollution such as warm water fish breeding ponds.

Wetland management is an active process of supporting ecosystem services, because human activity simultaneously extracts economic and social benefits from ecosystem services, so in order to maintain these services for a long time and sustainably, quick balance through planning and decision appropriate selection is required. In Iran, based on the 4th, 5th and 6th development plans of the country, the Environmental Protection Organization has been obliged to implement the ecological management program in cooperation with other organizations and main stakeholders. The Integrated management plan is a strategy for the integrated management of water, land and livelihood resources that promotes conservation and sustainable use in a balanced manner. Integrated management plan of Amirkelayeh international wetland has been prepaired in the form of an international plan for the protection of Iran's wetlands. The method used is strategic planning system. This management plan has been prepared based on the results of educational and consultative workshops and with the participation of representatives of major local and provincial groups. In this research, the general framework of the prepaired plan, including strategic and special objectives, and priority actions to achieve the final goal and vision, has been examined.
