Book Description
The Wild Salmon Policy (WSP) outlines Fisheries and Oceans Canada's (DFO) strategies for managing Canada's salmon resources. The status assessment (Strategy 1) involves developing benchmarks and determining the biological status of Conservation Units (CUs). In order to apply the WSP status assessment strategy to Interior Fraser Coho (IFC) salmon (Oncorhynchus kisutch), abundance-based benchmarks were calculated, based on previously published methods, and a comprehensive set of population dynamics, abundance, trend, distribution, and productivity information were reviewed for each of the five CUs. This assessment found no evidence that smolt-adult survival has improved or returned to the higher productivity regime. Because the productivity is low, the sustainable harvest that can be expected from the management unit is also low relative to historic levels.

Book Description
Assessments of the conservation status of species depend on using multiple indicators, and most methods for combining indicators either assume that all indicators are equally important or they use some other pre-determined weighting. This article discusses the case of Canada's Wild Salmon Policy, which requires that the biological status of Conservation Units (CUs) of Pacific salmon (Oncorhychus spp.) be assessed by combining the status of several indicators or metrics. We developed a questionnaire for experts based on stated preference methods and found that the status of spawner abundance and trend in spawners metrics had the highest relative importance in assessment of CU status, especially for cases with high data quality and amount (DQA). Without information on metric status, DQA had little influence on CU status ratings. Our study presents a novel method for combining indicators to assess conservation status, and in future could be applied to other species and contexts.

Book Description
"We developed an approach to rapidly assess the biological status of Pacific Salmon Conservation Units (CUs) under the Wild Salmon Policy (WSP). This approach assigns a Red (poor), Amber (intermediate), or Green (good) status, with High, Medium, or Low confidence, to CUs with applicable data. Existing integrated WSP status assessment approaches are labour intensive, and therefore, have only been completed for ~11% of the ~377 current Pacific Salmon CUs, and have not been updated since they were assigned in expert workshops. The WSP rapid status approach can provide a more complete and current picture of status across Pacific salmon species in BC & the Yukon. We developed seven candidate WSP rapid status algorithms based on completed WSP integrated status assessments, evaluated algorithm performance against a set of criteria, and identified the best performing algorithm. WSP rapid statuses are incorporated into DFO's new Pacific Salmon Status Scanner, an interactive data visualization tool for salmon experts. Rapid statuses in DFO's Salmon Scanner will be combined with expert review to support Fisheries Act Stock Management Unit (SMU) Limit Reference Point (LRP) status requirements, state of salmon reporting, climate change vulnerability assessments, and planning, prioritization and monitoring of hatchery, harvest and habitat actions"--Abstract, page xi.

Book Description
A key component of the Wild Pacific Salmon Policy is the conservation & stewardship of habitat for wild Pacific salmon. To focus & support habitat conservation & stewardship efforts, a suite of indicators at a range of scales is needed. This report represents a consolidation of a background information review & workshop project conducted to provide an overview of the state of habitat indicator development for wild Pacific salmon and to propose candidate indicators. After an introduction on the Wild Pacific Salmon Policy and the project study approach, chapter 2 presents an overview of Pacific salmon life history stages, habitat utilization, and relationships between salmon production & habitat characteristics. Chapter 3 summarizes previous activities related to development of salmon habitat indicators and frameworks for indicator selection. Chapter 4 contains a table of candidate indicators of habitat status. Chapter 5 lists data sources in British Columbia to support the candidate indicators. Chapter 6 briefly discusses several watershed-based programs related to wild Pacific salmon habitat & indicators. Chapter 7 is a summary of the salmon habitat indicator workshop findings; the full workshop report is appended. The final chapter makes recommendations for identifying a suite of habitat indicators with a view to optimizing the potential for successful implementation. Other appendices include a detailed preliminary analysis of the candidate indicators.
