Wetlands and Urbanization: Implications for the Future
The Puget Sound Wetlands and Stormwater Management Research Program (PSWSMRP) was a ten-year regional research effort documenting how urbanization affects wetlands. The studies examined the impacts of stormwater on the five major structural components of wetlands: (1) hydrology, (2) water quality, (3) soils, (4) plants, and (5) animals. The fourteen papers in this monograph are divided into four sections: Program Overview, Descriptive Ecology, Assessment of Stormwater Effects, and Management Guidelines.
