Impacts on Quality of Inland Wetlands of the United States: A Survey ofIndicators, Techniques, and Applications of Community-Level Biomonitoring Data

摘要

The report focuses on inland wetlands of the conterminous United States. Exceptfor those bordering the Great Lakes, these are not subject to significant tidal fluctuations. They are generally fresh water wetlands, except for saline wetlands in some mid-continent and western regions. Other tidal, tundra, and tropical wetlands were not included because their consideration would have involved a greatly expanded scope of work. Protocols for biological sampling of tidal wetlands have been presented by Simenstad et al. and others. For purposes of this report, 'wetlands' are considered to be vegetated areas transitional between uplands and open water. A principal goal of the report is to encourage each state to track their progress in protecting wetland ecological condition. It emphasizes
