Here we describe one conservation tool that will help to identify particularly significant river basins of the North Pacific for the conservation of salmon: the first Pacific-Rim wide assessment of salmon populations at a consistent scale. In conjunction with a scientific advisory panel and a peer review workshop we developed four criteria for the Pacific Salmon Conservation Assessment (PSCA) to provide an indication of aquatic ecosystem and salmon population resilience at the basin scale. These criteria are salmon abundance, diversity, hatchery influence, and landscape suitability. Highly abundant salmon populations have more “cushion” with which to absorb anthropogenic or natural disturbance (Quigley and...

Across the Pacific Northwest, both public and private agents are working to improve riverine habitat for a variety of reasons, including improving conditions for threatened and endangered salmon. These projects are moving forward with little or no knowledge of specific linkages between restoration actions and the responses of target species. Targeted effectiveness monitoring of these actions is required to redress this lack of mechanistic understanding, but such monitoring is in turn dependant on detailed restoration information; i.e. implementation monitoring. We assembled a database of restoration projects intended to improve stream and river habitat throughout the Pacific Northwest. The database was designed...

State of the Salmon GIS staff appended, cleaned, and clipped the basins to the North Pacific extent area. This coverage was then edited, by manual digitizing, checking accuracy against a 1:1,000,000 streams coverage, digital elevation models, and 4th field watershed boundaries where available. This process mostly entailed eliminating erroneous inclusion and exclusion of upper stream reaches within Hydro1k boundaries. When more detailed streams were consulted in the Pacific Northwest, Hydro1k basins could have been refined further and were in the cases when it affected distribution of salmonids at the time of processing (Summer 2004). This finer resolution stream data was not used extensively to maintain a consistent...
