Description

Abstract: The Oregon Department of Fish and Wildlife (ODFW) Aquatic Inventories Project conducts stream habitat surveys as part of the Oregon Plan for Salmon and Watersheds. The goal of these surveys is to document the status and trends of stream conditions that exist in coastal drainages of western Oregon. To better interpret landscape patterns in aquatic habitat character, the Aquatic Inventories Project has sought to improve the definition of a set of reference conditions from which to compare habitat survey sites. Over the past three years, the set of reference conditions used in analyses was selected from basin-wide habitat surveys conducted between 1992 and 1997. These conditions did not adequately represent the variety of stream sizes, geologic types, or ecoregions present in all coastal streams. The Aquatic Inventories Project selected a set of new reference survey locations that better represent reference conditions in coastal streams for a variety of ecoregions, geologic types, and basins. The reference sites selected for the year 2000 represented watershed areas with low impact from human activities such as roads, development, and forest management. Ideally, areas would have been selected that were completely free from human disturbance, but we concluded it was more important to represent a larger geographic range of conditions across the landscape.
