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...

Increased water use associated with rapid growth in the Las Vegas Valley has inadvertently led to the creation of unique wetland systems in Southern Nevada with an abundance of biological diversity. Constructed and naturally created wetlands in the Las Vegas Valley watershed were studied to characterize and understand their potential role for improving ecosystem services (i.e., water purificati...

Salinization, a widespread threat to the structure and ecological functioning of inland and coastal wetlands, is currently occurring at an unprecedented rate and geographic scale. The causes of salinization are diverse and include alterations to freshwater flows, land-clearance, irrigation, disposal of wastewater effluent, sea level rise, storm surges, and applications of de-icing salts. Climat...

Wetlands harbor an important compliment of regional plant diversity, but in many regions data on wetland diversity and composition is still lacking, thus hindering our understanding of the processes that control it. While patterns of broad-scale terrestrial diversity and composition typically correlate with contemporary climate it is not clear to what extent patterns in wetlands are complimenta...

external costs of environmental degradation are often ignored in economic analysis of projects. the mail goal of the paper is to economically analyze the current alternatives of meighan wetland utilization including extraction of sodium sulfate, aquaculture of artemia and integrative alternative considering external costs of wetland degradation. in order to detect eventual degradation of wetlan...

F.1.1 Current Wetland Area and Rates of Loss The ability to estimate soil carbon pools and fluxes in North American wetlands is constrained by the national inventories (or lack thereof) for Canada, the United States, and Mexico (Davidson et al., 1999). The National Wetland Inventory (NWI) program of the United States has repeatedly sampled several thousand wetland sites using aerial photographs...

Wetlands provide habitat for a diverse array of aquatic and semiaquatic species, many of which provide direct economic and recreational value (Woodward and Wui 2001). Despite the provided by wetland fauna and flora, ecosystem services historical wetland loss has been dramatic. Wetland loss was >50% in the U.S. and 60-70% in Europe by the 1980s, with most losses resulting from agriculture and ur...

Information about wetland dynamics remains a major missing gap in characterizing, understanding, and projecting changes in atmospheric methane and terrestrial water storage. A review of current satellite methods to delineate and monitor wetland change shows some recent advances, but much improved sensing technologies are still needed for wetland mapping, not only to provide more accurate global...

18 This paper presented an integrated conceptual model to describe the substrate 19 clogging in constructed treatment wetland. The model is based on pore space 20 reduction of the wetland substrate during the integrated treatment processes including 21 physical, biological and plant-related processes. A group of laboratory scale 22 constructed wetlands (CWs) was employed to set up the experimen...

ghourighol international wetland which is located at bostan-abad conuty in east azerbaijan province is known as one of the important tourism and promenade zone of iran due to its special natural gravities. therefore, studying tourism value of this place could express the importance of its protection, predicting needs, removing scarcities and the development of tourism. the aim of this research ...
