Throughout the Pacific Northwest, stream habitat degradation has been cited as a factor contributing to the decline and ESA listing of of Pacific Salmon. Thus, stream habitat restoration is a major component of recovery plans as a method to increase salmon population productivity. Over 10 years after the majority of salmon listings we now have many datasets available to evaluate salmon habitat restoration placement, including our restoration projects database (Pacific Northwest Salmon Habitat Project Database), habitat assessments, salmon recovery plans, and spatial habitat mapping. By creating data dictionaries and metrics to standardize and analyze currently available datasets (e.g., restoration data, recovery plans, monitoring data, population abundance data) evaluations can be made to determine whether the right types of habitat actions are going in where they are most valuable. Further, a quantitative framework can be developed to link habitat conditions to fish population condition through stream restoration actions. This information can them be provided to local groups and agencies involved in salmon recovery to help inform the adaptive management process.

The Multnomah Channel Wetland Restoration Monitoring Project characterizes wetlands use by juvenile salmonids and other fishes in the Multnomah Channel Marsh Natural Area (MCMNA) and nearby habitats of the Columbia River estuary. The project is a collaborative program by federal, state, and municipal organizations evaluating the ecological effectiveness of floodplain restoration actions at the MCMNA on behalf of at-risk juvenile salmonids. The project uses a wide range of sampling methods to document fish, invertebrate prey, vegetation, and physical habitat conditions and to experimentally assess salmon performance. Sampling methods include: PIT arrays and remote detection systems to monitor salmon access, residency, and movements to and from the wetland; experimental net pens to compare salmon food and relative growth potential within different vegetation types; beach seines, traps, PIT detectors, electro-shockers, and other gear to monitor fish abundance and salmon stock composition; and benthic cores, insect fallout traps, emergent traps, and neuston nets to determine invertebrate prey composition, abundance, and transport from the wetland site. Fish samples are also collected along the main-stem estuary, Multnomah Channel, and other wetlands to investigate the effects of river flow and water elevation on fish access to the MCMNA. Invertebrate and fish stomach samples are analyzed at the main campus of Oregon State University (Corvallis, OR) and at the Oregon Department of Fish and Wildlife Corvallis Research Laboratory. Other activities, vessels, and sampling equipment are staged from the Pt. Adams Research Station in Hammond, OR.

A study to evaluate the role of changing ocean conditions on growth and survival of juvenile salmon from the Columbia River basin as they enter the Columbia River plume and Pacific Northwest coastal habitats. Adult returns vary dramatically (over 10 fold) as a result of changing (good or bad) ocean conditions juveniles experience. Evaluating the benefit of restoration efforts in the Columbia River to restore endangered salmon populations needs to consider ocean conditions as a contributing factor to recovery. This is a large collaborative project with contributions from NWFSC, Oregon State University, and Oregon Health and Science University. The work focuses on three objectives: 1) Determining the distribution, growth, and condition of juvenile Columbia River Chinook and coho salmon in the plume and their ocean environments with associated physical and biological features, and effects on salmon survival via regular spring and summer surveys. 2) Using additional focused surveys to obtain critical pieces of information on predator impacts, specific food resources, biological condition, and means by which juvenile salmon exit the Columbia River estuary. 3) Synthesizing the early ocean ecology of juvenile Columbia River Chinook and coho salmon, test mechanisms that control salmonid growth and survival, and produce ecological indices that forecast salmonid survival. This project provides critical information on marine survival to the Columbia River salmonid management community (hydrosystem, harvest, hatchery, and habitat management) provides environmental indicators useful for forecasting salmon returns, and provides a greater understanding of ecological controls on salmon populations. This is a long-term monitoring and research project initiated in 1998. Species, abundance, and distribution of birds during salmon surveys.

Sampling juvenile salmon and associated fishes in open waters of the lower Columbia River estuary. Field work includes bi-weekly sampling during the spring outmigration (Apr-June), and monthly sampling throughout the summer and fall. We use a purse seine to sample open water habitats. Our objectives are to document the seasonal and interannual variation in juvenile salmon immediately prior to ocean entry, with respect to abundance, size, origins (H/W), stocks, food habitats, and parasites/pathogens. We also document the larger estuarine fish community, which serves a critical role as prey for juvenile salmon predators. Abundance and size of fish caught in Columbia estuary.
