RMECAT-2009-004-00Proposal Version 1Existing ProjectPending BPA Response2009-004-00Monitoring Recovery Trends in Key Spring Chinook Habitat Variables and Validation of Population Viability IndicatorsThe proposal has two major components that are identified below: 1.Habitat degradation is attributed as a significant cause for the decline of numerous salmonid populations. The key objective of this proposal is to identify areas that have depressed populations within a sub-basin in the Columbia, and establish habitat conditions for these populations at various scales. Over the next 10-year period, various aspects of the habitat and fish populations will be inventoried, and treatment-control and before-after control impact (BACI) designs will be applied to both habitat conditions and population attributes (abundance and productivity) on these sub-basins. 2.The second phase of this project will be developed after baseline habitat data are collected and will focus on life cycle-based models for spring Chinook salmon. The approach used will develop life-cycle specific models to address life-history complexities, and intends to capture inter-annual variation in recruitment as a function of freshwater and early ocean/estuary variation. Based on data collected from the previous sections overlayed with life-history parameters, we will develop a quantitative modeling approach to estimate the annual variation in recruitment (and survival). This approach will probably use a collaborative effort with other agencies in the region (e.g., ODFW and NMFS) and tribes (e.g., CTUIR) that may have similar objectives.Bryan Mercier (Inactive)06/01/201007/08/2011Bryan Mercier (Inactive)Bioanalysts, Inc., Columbia River Inter-Tribal Fish Commission (CRITFC), Fisher Fisheries Ltd., Paulsen Environmental Research Ltd., Tetra Tech, Inc.ProgrammaticNoneRME / AP Category ReviewRM&E Cat.
