Wetlands and Urbanization Implications for the Future Report of the Puget Sound Wetlands and Stormwater Management Research Program, 1997 For a more up-to-date version of this report, please visit CRC press. Edited by Amanda L. Azous and Richard R. Horner Washington State Department of Ecology, Olympia, WA King County Water and Land Resources Division, Seattle, WA University of Washington, Seattle, WA Washington State University Cooperative Extension, Seattle, WA The Puget Sound Wetlands and Stormwater Management Research Program (PSWSMRP) was a ten-year regional research effort intended to document the impacts of urbanization on wetlands. The wetlands included in the study were representative of those found in the Puget Sound Lowlands ecoregion, most likely to be impacted by urban development. The program’s goal was to to employ research results to improve the management of both urban wetland resources and stormwater. 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. You may download the entire report or any individual chapters. The files are stored in Microsoft Word Version 6.0 format, and have been compressed for faster downloading.

This chapter describes the impetus behind the program, and the issues facing the program at its inception. It summarizes the state of knowledge on these issues at the beginning and in the early stages of the program. The paper concludes with an outline of the general experimental design of the study. SECTION 2 DESCRIPTIVE ECOLOGY OF FRESHWATER WETLANDS IN THE CENTRAL PUGET SOUND BASIN. These chapters provide a descriptive ecology of the palustrine wetlands of the central Puget Sound Lowlands, organized according to the major structural components monitored during the program.
