Juvenile Chinook Salmon (Oncorhynchus Tshawytscha) Residency And Early Growth In The Lower Fraser River Estuary, Lia Chalifour, David Scott, Misty Macduffee, John Dower, Julia Baum

Salish Sea Ecosystem Conference

The Fraser River has historically supported the most abundant salmon runs in North America, which have been declining for decades. Despite its importance and ongoing threats of climate change and habitat degradation, the Fraser River estuary is particularly understudied, with the latest comprehensive fish survey occurring in the early 1980s. We were particularly interested in the role of estuarine habitat in supporting juvenile salmon during the critical outmigration period. As part of a two-year study, which surveyed 20 sites in the lower estuary across three habitat types, we sampled over 3,000 juvenile Chinook salmon. We caught the majority of all …

Fir Island Farm: Estuary Restoration Project: Designing For Climate Change And Uncertainty In Shoreline Flood Risk Reduction And Ecosystem Restoration Projects, David Cline

Salish Sea Ecosystem Conference

The recently designed and constructed Fir Island Farm – Estuary Restoration Project involves construction of a 1-mile long shoreline levee (dike) setback for restoration of 130 acres of farm land for tidal marsh estuary ecosystem restoration. The key uncertainty, and resiliency, design elements of concern include 1) selection of dike level of protection and design elevations considering climate change sea level rise projections, 2) inclusion of erosion protection measures, 3) farm drainage tailwater conditions and 4) ecosystem marsh vegetated plain future elevations and large woody debris loading conditions. This presentation discusses how site characterization, instrumentation, numerical modeling and monitoring were …


Assessing The Effects Of Chemical Mixtures Using A Bayesian Network-Relative Risk Model (Bn-Rrm) Integrating Adverse Outcome Pathways (Aops) In Three Puget Sound Watersheds, Valerie Chu, Meagan J. Harris, Chelsea J. Mitchell, John D. Stark, Katherine E. von Stackelberg, Wayne G. Landis 2018 Western Washington Univ., United States

Assessing The Effects Of Chemical Mixtures Using A Bayesian Network-Relative Risk Model (Bn-Rrm) Integrating Adverse Outcome Pathways (Aops) In Three Puget Sound Watersheds, Valerie Chu, Meagan J. Harris, Chelsea J. Mitchell, John D. Stark, Katherine E. Von Stackelberg, Wayne G. Landis

Salish Sea Ecosystem Conference

Chemical mixtures are difficult to assess at the individual level, but more challenging at the population level. There is still little insight of the molecular pathway for numerous chemical mixtures. We have conducted a regional-scale ecological risk assessment by evaluating the effects chemical mixtures to populations with a Bayesian Network- Relative Risk Model (BN-RRM) incorporating a molecular pathway. We used this BN-RRM framework in a case study with organophosphate pesticide (OP) mixtures (diazinon, chlorpyrifos, and malathion) in three watersheds (Lower Skagit, Nooksack, Cedar) in the state of Washington (USA). Puget Sound Chinook salmon (Oncorhynchus tshawytscha) Evolutionary Significant Units (ESU) were …

Latitudinal Variation In Seagrass Wasting Disease From Puget Sound To Alaska, Olivia Graham, Corinne Klohmann, Emily Adamcyzk, Margot Hessing-Lewis, Angeleen Olson, Nick Tolimieri, Tiff Stephens, Colleen Amy Burge, Drew Harvell

Salish Sea Ecosystem Conference

Widely regarded as critical marine habitat, seagrass provides ecologically and economically valuable services in coastal areas worldwide. Eelgrass (Zostera marina) is one of five seagrass species native to the Pacific Northwest and is threatened by outbreaks of the marine protist Labyrinthula zosterae, the causative agent of seagrass wasting disease. Infection from L. zosterae causes necrotic lesions, limiting growth and compromising the health of eelgrass beds. To determine levels of wasting disease in subtidal eelgrass beds across a broad latitudinal gradient, we measured and compared disease prevalence and severity in 5 subtidal eelgrass beds in Puget Sound, 5 in the San …

Collaborative Solutions To Riparian Protection And Restoration In The Chimacum Creek Watershed, Sarah Doyle 2018 North Olympic Salmon Coalition, United States

Collaborative Solutions To Riparian Protection And Restoration In The Chimacum Creek Watershed, Sarah Doyle

Salish Sea Ecosystem Conference

For several decades, the North Olympic Salmon Coalition (NOSC) has been working with agricultural producers in the Chimacum Creek Watershed to plant riparian buffers and restore salmon habitat. In recent years, NOSC and partners have had difficulty engaging landowners to participate in riparian restoration and protection programs due to issues regarding drainage, reed canary grass and beaver damage. To help guide us in how to address these barriers to landowner willingness, NOSC partnered with local entities to develop a Chimacum Creek Protection and Restoration Strategy. Since the strategy has been implemented, four priority farms are now being considered for protection …

Watershed Assessment Modelling To Identify Critical Sources Of Pollution And Evaluate Effectiveness Of Conservation Management Practices, Nichole Embertson, Meagan Harris, Andrew Phay

Salish Sea Ecosystem Conference

Critical watershed assessments allow land managers to create strategic plans and prioritize funding and technical assistance when resources are limited. The Natural Resources Conservation Service (NRCS) National Water Quality Initiative (NWQI) provides a framework for watershed assessment to support long-term, strategic watershed planning and prioritize resources. The Tenmile Watershed in the Nooksack Basin in Whatcom County was selected as a pilot watershed for the NWQI assessment for Washington State in 2017. The primary objective of this assessment was to identify critical source areas (CSAs) within the watershed that were most susceptible to nutrient, sediment and bacteria export based on physical …


A Practical And Informative Sandpiper Monitoring Procedure For The Salish Sea, Ronald Ydenberg, Dov B. Lank, Richard Johnston, David Hope, Rachel Canham 2018 Simon Fraser Univ., Canada

A Practical And Informative Sandpiper Monitoring Procedure For The Salish Sea, Ronald Ydenberg, Dov B. Lank, Richard Johnston, David Hope, Rachel Canham

Salish Sea Ecosystem Conference

The Salish Sea contains important sites for shorebirds, including migrants and winter residents. There is a need for practical, informative and easily-applied monitoring procedures and goals. Counts at stopover sites are on their own uninformative, because they are strongly affected by factors unseen by local observers. A fall in the usage of a site might signal a global population decline, but could also be due to a reduction of that site’s quality, to an increase in site quality elsewhere such that some birds redistribute, or to changes in migratory behavior. A good framework for assessing the health of shorebird populations …


The Effects Of Diluted Bitumen (Dilbit) Exposure During Embryonic Development On The Future Swimming Performance And Metabolic And Ionic Recovery Post-Exercise In Sockeye Salmon (Oncorhynchus Nerka), Feng Lin, Chris Kennedy 2018 Simon Fraser Univ., Canada

The Effects Of Diluted Bitumen (Dilbit) Exposure During Embryonic Development On The Future Swimming Performance And Metabolic And Ionic Recovery Post-Exercise In Sockeye Salmon (Oncorhynchus Nerka), Feng Lin, Chris Kennedy

Salish Sea Ecosystem Conference

Expansions in the transportation of diluted bitumen (dilbit) products in coastal regions of British Columbia potentially increase the risk of exposure of early life stage (ELS) Pacific salmon by both acute as well as sublethal effects. The objective of present study was to investigate the effects of dilbit exposure (from the embryonic to swim-up sockeye (Oncorhynchus nerka) on their swimming performance and exercise recovery at later life stages (juveniles). Embryos were exposed to 4 concentrations (0, 13.7, 34.7 and 124.5 μg/L total PAH [TPAH]) of the dissolved fraction of Cold Lake Winter Blend dilbit immediately following fertilization until swim-up. The …

Snoqualmie Valley Agricultural Production District Riparian Restoration And Ag Partnership Building: Emds Pilot Project, Kollin Higgins

Salish Sea Ecosystem Conference

This project occurred at the tail end of a broader King County engagement effort in the Snoqualmie River Valley between farming, fish, and flood risk reduction interests that recognized large scale riparian restoration could have a broad effect on the amount of land being used for agriculture. King County worked with the US Forest Service, the King Conservation District and local farmers to develop an Ecosystem Management Decision Support (EMDS) model to transparently and quantitatively evaluate the value of 10 miles of the Snoqualmie River for riparian restoration and agricultural land value. This approach allowed the county to focus its …


If You Build It, They Will Come: Marine Habitat Provided By A Wastewater Outfall, Kimberle Stark, Jeffrey Lundt, Wendy Eash-Loucks 2018 King County, United States

If You Build It, They Will Come: Marine Habitat Provided By A Wastewater Outfall, Kimberle Stark, Jeffrey Lundt, Wendy Eash-Loucks

Salish Sea Ecosystem Conference

King County built a new marine outfall in 2008 that discharges treated wastewater effluent to the Puget Sound Central Basin about 1.6 kilometers offshore at a depth of 183 meters (m). The outfall consists of two 1.6 m diameter HDPE pipes weighted with concrete anchors. To assess the artificial reef effect of the exposed pipes and its use as habitat by marine organisms, underwater video has been collected annually since 2009 at the shallower depths (to -91 m MLLW). Initial video showed rapid colonization by barnacles and other invertebrates. Several rockfish species have routinely been seen on the pipes, particularly …


The Chemical And Biological Effectiveness Of Bioretention For Preventing Sublethal And Lethal Toxicity In Coho Embryos Exposed Episodically To Urban Stormwater Runoff During Development, Jenifer K. McIntyre, Jessica I. Lundin, Jay W. Davis, John Incardona, Julann Spromberg, Nathaniel L. Scholz 2018 Washington State University

The Chemical And Biological Effectiveness Of Bioretention For Preventing Sublethal And Lethal Toxicity In Coho Embryos Exposed Episodically To Urban Stormwater Runoff During Development, Jenifer K. Mcintyre, Jessica I. Lundin, Jay W. Davis, John Incardona, Julann Spromberg, Nathaniel L. Scholz

Salish Sea Ecosystem Conference

Green stormwater infrastructure (GSI) includes an evolving set of technologies to mitigate the physical and chemical habitat degradation that results from urban runoff entering aquatic ecosystems. Bioretention is a common GSI approach, used, for example in rain gardens, to infiltrate stormwater runoff into soils prior to or instead of discharging into a water body. Initial research has shown that bioretention is biologically effective for preventing most toxicity from urban runoff exposure, but initial trials used fresh bioretention soil media (BSM) with less than 5 repeated treatments. Does bioretention continue to be biologically effective at preventing toxicity over more treatment events? …

Development And Application Of Lc/Ms Based Analysis For Marine Algal Toxins In Hood Canal, Sang Seon Yun, Aaron Bentson-Royal, Kenneth Collins, Seth Book, Ron Figlar-Barnes

Salish Sea Ecosystem Conference

Harmful algal toxins have been well recognized as public health threats (James et al., 2010; Van Dolah, 2000), and a multitude of measures to prevent harmful algal blooms (HABs) derived health risks have been proposed and implemented (Trainer and Hardy, 2015). Coastal communities such as the Skokomish Indian Tribe, consuming a large amount of shellfish to meet their dietary needs are particularly vulnerable to such risks. Washington Department of Health (DOH) has been monitoring marine algal toxins in Puget Sound including coastal areas by collecting shellfish samples followed by mouse-based toxin analysis. To address on-going and future marine algal toxin …
