Threat problemology by Tree analysis Technique in The ecosystem integrated management plan(Case Study: Amirkelayeh refuge)

The necessity of wetland management and conservation based on a comprehensive and integrated approach by attracting cooperation and participation of individuals, organizations, and groups in the community (stakeholders) is inevitable. The ecological approach is a strategy for the integrated management of water, land, and livelihood resources that promotes sustainable conservation and sustainable use in a balanced way . In this article, the problems of the wetland were investigated using the tree analysis Technique (facilitation technique) resulting from holding participatory workshops in the Amirkelayeh ecosystem integrated management plan. The results of drawing problem trees in working groups showed biodiversity problems consist of insufficient manpower and protective equipment, illegal hunting and fishing, the entry of invasive and non-native species, wildlife diseases, increasing of sediments caused by the decomposition of plants. These problems have created impacts including eutrophication, reduction of species diversity, and population of species, especially the population of native and migratory birds. In the socio-economic field, problems such as lack of awareness of managers and local communities about the functions of the wetland, lack of inter-organizational interaction, occupation land, and change of land use, intentional and unintentional fire, interference of the guide plan of Hassan-Bakandeh, and Amirabad village With the area of the wetland, and livelihood and economic problems causes habitat destruction. The Water- soil problems section consists of the entry of agricultural wastewater (fertilizers and pesticides), water withdrawal by unauthorized pumping, non-dredging of drains entering the wetland have caused consequences such as soil and water pollution, reduced surface area, and depth of water area. The sum of the results showed cannot be prevented from irreparable and progressive destruction also loss of its values and function if the Amirkelayeh ecosystem integrated management plan was not implemented.
