The Field Assessed Benefit and Design Strategy (FABADS) was introduced by the U.S. Army Cops of Engineers as part of the Upper Susquehanna River WatershedCooperstown Area Ecosystem Restoration Feasibility Study and Integrated Environmental Assessment. Authorized by the U.S. Congress, the pilot program is “to conduct a study and develop a strategy for using wetland restoration, soil and water co...
The Glaciated Interior Plains historically supported a broad variety of wetland types, but wetland losses, primarily due to agricultural drainage, range from 50% to 90% of presettlement area. Wholesale land use change has created one of the most productive agricultural regions on earth, but wetland conversion has also led to the loss of the ecosystem services they provide, particularly water qu...
The aim of this study is to assess the risk factors of pipelines and prioritize their severity in order to prevent their effects in Shadegan International wetland, Iran. Due to the participatory nature of the managerial affairs, the study employs an integrated approach that combines Analytic Hierarchy Process (AHP) and Delphi Method. Also, Likret Scale has been applied to quantify the qualitati...

The United States has lost about half its wetland acreage since European settlement, and the effectiveness of current wetland mitigation policies is often questioned. In most states, federal wetland laws are overseen by the U.S. Army Corps of Engineers, but Michigan administers these laws through the state's Department of Environmental Quality (MDEQ). Our research provides insight into the effe...
Inland wetlands are of the most important natural terrestrial types of water resources. Against its importance in protecting and improving biodiversity, air quality and macro-climatic condition of their regions, industrial development, and urbanization treat their natural existence and behavior. Therefore, monitoring and quality evaluation of wetlands are necessary to analyze and infer their na...

background: in the recent years, eutrophication has become a serious challenge for many of the water ecosystems. it has affected the environmental and economical aspects of the anzali wetland, which is known as one of the significant ecosystem. due to the increase of the nutrient loadings from the industrial, agricultural and human activities, the wetland’s health is faced many serious problems...
To understand long-term changes in Chicago region wetlands, in 2002 we investigated the status of 31 high quality grassor sedge-dominated wetland plant communities that were originally sampled in 1976. Our objectives were to quantify vegetation changes over time by resampling transects and then correlating changes with site fire histories, as well as other factors linked with compositional and ...
environmental and strategic assessment of ecotourism potential in anzali wetland using swot analysis
swot analysis is used extensively as an assessment and planning method, particularly in tourism planning. however, there are little documentations on application of swot analysis in ecotourism. an assessment on systematic use of swot analysis was carried out in the present study to highlight the applicability of the swot technique in detailed investigations. in this study, based on field survey...
