Wetlands and Urbanization

Book excerpt: Urbanization affects wetlands in direct and indirect ways. Over the past several decades it has become increasingly apparent that unmanaged runoff is the primary threat to the country's watershed resources. Wetlands and Urbanization: Implications for the Future is the result of a ten year research project focused on the understanding and managing the impacts of urban stormwater on wetlands. The book documents the background, methods, and results of the research and uses the information to draw conclusions about managing wetland ecosystems in urban areas. The project culminates in a set of comprehensive guidelines for the management of wetland hydrology. While the focus of this research is regional in nature, its applications are broad. First, the research shows how to measure and assess the impact of urbanization on wetlands. Secondly, it presents scientific approaches available for use in an integrated assessment of wetland condition. And thirdly, it provides guidelines for biomonitoring wetlands using multiple indicators. Wetlands and Urbanization presents an integrated watershed approach to the scientific evaluation of the impact of landscape urbanization on wetland functions. It associates the source of impact (the landscape) with the sink (the wetland), relates findings to implications for future planning and management of watersheds and provides a model for future comprehensive investigations of wetland impacts from urbanization.
