ABSTRACT
Quantitative habitat surveys have been conducted in western Oregon streams since 1990. Over 950 streams, a total of 6,000 kilometers, have been surveyed in coastal basins with the results organized into over 3,100 reaches characterized by land use, channel morphology, and valley form. The data have been compiled into a comprehensive database that describes key attributes of instream habitat, riparian structure, and channel morphology. The information was used to describe current status of habitat throughout the coastal basins and the potential to support coho salmon Oncorhyn-chus kisutch populations. Example maps and evaluations were developed for the Yaquina River watershed to describe and compare coho salmon habitat. The datasets will support sustainability because they can be used to estimate potential survival and production of juvenile coho salmon in coastal basins, to identify core habitats, for designing and evaluating monitoring programs, and for developing restoration strategies.
