Influence of Habitat Compexity and Floodplain Reconnection Projects on the Physical and Biological Conditions of Seattle Urban Streams: Pre-Project Monitoring: Final Progress Report, 2005-2007

摘要

We documented pre-restoration physical and biological conditions at four reaches in Thornton Creek, 95th Street, N.F. Confluence, S.F. Confluence, and Knickerbocker. For each study site (treatment) a control reach was selected. The purpose of this report is to provide a summary of pre-project data collected during the first year and a half of this long-term monitoring project to evaluate the effectiveness of Seattle Public Utilities (SPU) habitat complexity projects. Physical conditions documented included channel morphology, streambank condition, vegetation, regional surface/groundwater interactions, and hydraulic interactions, and instream habitat. Biological conditions included fish, benthic invertebrates, and periphyton.
