Responses Of River-Dependent Wildlife To Dam Removal, Salmon Restoration, And Nutrient Subsidies In The Elwha River Watershed, Olympic Peninsula, Washington, Kim Sager-Fradkin, Christopher M. Tonra, Peter P. Marra
Responses Of River-Dependent Wildlife To Dam Removal, Salmon Restoration, And Nutrient Subsidies In The Elwha River Watershed, Olympic Peninsula, Washington, Kim Sager-Fradkin, Christopher M. Tonra, Peter P. Marra
Salish Sea Ecosystem Conference
The ongoing removal of two hydroelectric dams from the Elwha River on Washington’s Olympic Peninsula provides an unprecedented opportunity to study the effects of dam removal and subsequent salmon restoration on river-dependent wildlife species. Salmon are widely known to distribute marine nutrients into freshwater systems, providing benefits to both riverine and upland wildlife communities through improved nutrient availability. We examined two species of river-dependent wildlife (river otter Lontra canadensis, and American dipper Cinclus mexicanus) to gather data on home range and seasonal movement patterns, body condition, and dietary contributions from marine-derived nutrients prior to and during dam removal. We radio-tracked …

Movement Of Transplanted Adult Salmonids In Previously Inaccessible Habitat In The Elwha River, Kinsey Frick, Raymond Moser, John Mcmillan, Sam Brenkman, Roger J. Peters
Salish Sea Ecosystem Conference
The removal of the Elwha and Glines Canyon Dams on the Elwha River will renew access for anadromous salmonids to 70 miles of high quality habitat located primarily within Olympic National Park. Concurrent dam removals began in 2011, with complete fish passage projected in 2014. While the long-term benefits to anadromous populations are undisputed, release of stored sediment behind the dams is temporarily elevating suspended solids and degrading existing spawning habitat downstream of the Elwha dam. To minimize deleterious effects in the lower river, give populations an early opportunity to spawn and imprint on upstream habitats, and examine the response …

Bringing Critical Systems Thinking To High School Students Through Ocean Acidification Research, Claudia Ludwig, Monica Orellana, Nitin S. Baliga
Salish Sea Ecosystem Conference
Ocean acidification is a complex phenomenon with complex consequences. Understanding this complexity and the impact of ocean acidification requires systems thinking and collaboration, both in research and in education. Scientific advancement will help us better understand the problem and devise more effective solutions, but executing these solutions will require widespread public participation to mitigate this local and global problem. We have translated current systems-level ocean acidification research into a 5 week high school curriculum module. We will present this curriculum which is easily implemented in schools and has resulted in a high level of engagement and learning. Thus far 13 …
A First Nation History And Approach To Acidification In Burrard Inlet, John Konovsky, Jesse Morin
A First Nation History And Approach To Acidification In Burrard Inlet, John Konovsky, Jesse Morin
Salish Sea Ecosystem Conference
In Burrard Inlet, the shellfish resources First Nations have traditionally relied upon are being affected by acidification. The archaeological record and traditional ecological knowledge coupled with long term data on pH levels can potentially be used to understand changes in species composition over the last 3000 years. However, because of 40 years of bivalve harvest restrictions, the effect of acidification on bivalve species composition has not been well recognized by First Nation communities. If the intention is to re-establish bivalve harvest opportunities in Burrard Inlet, First Nations will have to recognize and address acidification, perhaps by implementing recommendations from the …
Three Cost-Effective Public Domain On-Site Sewage Treatment Technologies Verified For Their Ability To Denitrify, Lynn Schneider
Three Cost-Effective Public Domain On-Site Sewage Treatment Technologies Verified For Their Ability To Denitrify, Lynn Schneider
Salish Sea Ecosystem Conference
Sewage typically contains high levels of nitrogen. Even with new technologies, on-site sewage (septic) treatment systems typically do not reduce nitrogen levels in treated wastewater. Cost effective on-site sewage systems with adequate denitrification capabilities are needed for areas where nitrogen has been determined a contaminant of concern. A collaborative effort between the Washington State Department of Health and the University of Washington Civil and Environmental Engineering Department was undertaken to design and evaluate cost effective, reliable, and low maintenance public domain treatment technologies that have high nitrogen removal efficiencies. The systems were installed and tested at the Snoqualmie Wastewater Treatment …
Use Of Viral Indicators To Assess Public Health Risk To Shellfish Growing Areas: A Case Study From Blaine, Washington, Mark Toy, Greg Goblick
Use Of Viral Indicators To Assess Public Health Risk To Shellfish Growing Areas: A Case Study From Blaine, Washington, Mark Toy, Greg Goblick
Salish Sea Ecosystem Conference
A hydrographic dye study of effluent from the Lighthouse Point Water Reclamation Facility in Blaine, Washington, was conducted in November 2012. Six cages filled with oysters were deployed at various locations (stations) along the anticipated path of the effluent to correlate the dye concentrations found at the cages with the indicator bacteria and viral findings in the oysters. Sampling was also conducted at the plant to assess bacteria and virus removal efficiencies through the treatment process. The study objectives were to: (1) determine the bacterial and viral conditions in the influent and effluent and removal efficiencies for a WWTP using …

Salish Sea Ecosystem Conference
Early Marine Survival (EMS) of Chinook and Coho salmon in the Salish Sea has plummeted over the past decades, and both bottom-up and top-down mechanisms for decline have been proposed. As a background for an ecosystem-based assessment of EMS, a pilot study on the basic oceanography of a small sub-component of the system was launched in spring and early summer, 2013. A repeat sampling grid covering Cowichan Bay and immediately connected waters was established, and then sampled on weekly intervals for temperature, salinity, chlorophyll fluorescence, nutrients and zooplankton. Oceanographic studies were carried out concurrently with fisheries assessments. A longer section …

Early Marine Survival Of Steelhead Smolts In Puget Sound, Megan Moore, Barry A. Berejikian, Frederick William Goetz, Thomas P. (Thomas Peter) Quinn, Sayre Hodgson, Ed Connor, Andrew Berger
Salish Sea Ecosystem Conference
Smolt-to adult survival rates for Puget Sound steelhead populations have declined substantially over the last 25 years and remain at or near historic lows. From 2006-2009, nearly 1,400 steelhead smolts from 9 watersheds within Puget Sound were tracked from river mouth to the Pacific Ocean using acoustic telemetry to: (1) estimate early marine survival through Puget Sound, (2) identify common areas of abnormally high mortality along the migration route, and (3) to identify factors that may influence survival. Cormac-Jolly-Seber mark-recapture models were used to jointly estimate survival and detection rate at telemetry arrays. Estimated survival rates from river mouths to …

Shoreline Armoring Disrupts Marine-Terrestrial Connectivity In The Salish Sea, With Consequences For Invertebrates, Fish, And Birds, Sarah M. Heerhartz, Megan Nichols Dethier, Jason David Toft, Jeffery R. Cordell, Andrea S. Ogston
Salish Sea Ecosystem Conference
Within the marine-terrestrial ecotone, upper intertidal “wrack zones” accumulate organic debris from algae, seagrass, and terrestrial plant sources and provide food and shelter for many organisms. We conducted detailed surveys of wrack and log accumulations and supralittoral invertebrates in spring and fall over 3 years at 29 armored-unarmored beach pairs in Puget Sound, WA, USA. Additionally, behavioral observations of juvenile salmon (Oncorhynchus spp.) and birds were conducted at 6 pairs. Armored beaches had substantially less wrack overall, a lower proportion of terrestrial plant material in the wrack, and far fewer logs. Armored beaches had significantly fewer invertebrates and differed from …
Salmonid Early Response To Restored Freshwater Floodplain, Erin Morgan, Jeffery R. Cordell, Lauren Rich
Salmonid Early Response To Restored Freshwater Floodplain, Erin Morgan, Jeffery R. Cordell, Lauren Rich
Salish Sea Ecosystem Conference
Shortly after the construction of the Hansen Creek floodplain restoration project in 2010-2011, we conducted a pilot study of the initial use of the site by juvenile salmonids and the early development of invertebrate communities. We found that juvenile Coho salmon collected from the restored floodplain during periodic inundation events had higher instantaneous rations (a measure of feeding intensity) than Coho collected during regular monthly sampling in the creek channels. The floodplain site also had consistently higher insect abundances. Applying the data and lessons learned from the pilot study, we undertook a more comprehensive 13-month study of Hansen creek and …
Effectiveness Monitoring - Time And Space Matter, Robert Duff
Effectiveness Monitoring - Time And Space Matter, Robert Duff
Salish Sea Ecosystem Conference
The goal of this talk is to provide an understanding of how we can link environmental change to management actions. So called "effectiveness monitoring" connotes a single-minded approach to linking restoration with response in an ecosystem. A more holistic concept of effectiveness monitoring will be presented where many different types of monitoring can be employed in an EM context depending on scale (time and space). The framework of adaptive management will be discussed to help define expectations of scale that mangers and policy-makers expect. Examples relevant to Puget Sound will be shown that illustrate a continuum of monitoring that is …
Making Washington’S Shoreline Master Programs Climate Smart, Jennifer Hoffman
Making Washington’S Shoreline Master Programs Climate Smart, Jennifer Hoffman
Salish Sea Ecosystem Conference
Shoreline Master Programs (SMPs) are the vehicle through which local jurisdictions implement Washington’s Shoreline Management Act, the legal framework for shoreline management throughout the State. While Washington’s coastal communities, economies, and ecosystems will see significant climate change impacts, including increased erosion, sea level rise, and ocean acidification, SMPs have not traditionally incorporated these factors. Ecology released interim guidance on incorporating sea level rise into SMPs in 2010, and is working on updated guidance now. This talk will focus primarily on options for incorporating climate change into the inventory and characterization (I&C) phase of the SMP process, which provides the scientific …
Shoreline Monitoring Toolbox: Development And Goals For Implementation, Jason David Toft, Kate Litle, Joleen Palmer
Shoreline Monitoring Toolbox: Development And Goals For Implementation, Jason David Toft, Kate Litle, Joleen Palmer
Salish Sea Ecosystem Conference
Shoreline monitoring is often a desired or required goal by volunteer groups and local entities, but protocols and guidelines can be hard to find and misleading if not used appropriately. We will present the initial developments of a Shoreline Monitoring Toolbox, an idea that progressed from its original concept at the Shoreline Restoration Monitoring Consortium in June 2013. Among the issues are the needs of local entities for a standardized approach for monitoring and a “toolbox” of protocols and information. Emphasis is placed on methods that are simple and affordable, and that can be used for monitoring restoration sites, establishing …

Symptoms Of Adult Coho Salmon Pre-Spawn Mortality Are Not Produced By Exposures To Artificial Mixtures Of Metals And Pahs., David Hugh Baldwin, Julann Spromberg, Jay W. Davis, Steven Damm, Jenifer K. Mcintyre, Nathaniel L. Scholz
Salish Sea Ecosystem Conference
Over the past decade, monitoring surveys in the greater Seattle area have revealed anomalous behaviors among adult coho salmon returning to spawn in restored urban streams. Behaviors included erratic surface swimming, gaping, fin splaying, and loss of orientation and equilibrium. Affected fish died within hours, and female carcasses showed high rates (> 90%) of egg retention. This phenomenon was termed coho pre-spawn mortality (PSM). From 2002-2012, rates of coho PSM ranged from ~ 30-90% in monitored urban streams. The severity of PSM was closely associated with fall rain events. Samples from affected coho exhibited evidence of exposure to metals and …
Meta-Analysis Of Project Effectiveness: Learning At The Regional Scale, Constance Amanda Sullivan, Leska S. Fore, Scott A. Collyard
Meta-Analysis Of Project Effectiveness: Learning At The Regional Scale, Constance Amanda Sullivan, Leska S. Fore, Scott A. Collyard
Salish Sea Ecosystem Conference
Many regional monitoring programs are designed to answer questions about the effectiveness of restoration or management actions. How do we evaluate regional effectiveness of restoration efforts from project scale studies? Regional decision-making depends on results from local-scale projects. Statistical meta-analysis provides a method for determining which restoration actions are the most effective. Meta-analysis is widely applied in other fields to evaluate the effectiveness of medical treatments and educational programs. We define an effectiveness study as one in which monitoring data are collected before and after a restoration action. Many examples of effectiveness monitoring studies exist in Puget Sound, including projects …

Grossman, Guy Gelfenbaum, Angela Lind-Null, Kimberly Larsen, Christopher A. Curran, Jean Takekawa, Lisa Belleveau, Peter W. Swarzenski, Robert E. Kayen, Anna Davenport
Salish Sea Ecosystem Conference
Restoration science is often described as an ultimate test of ecological theory; assessing the value of restoration actions is challenged by difficulties in measuring complex interactions between restored physical processes and the response of biological resources. Yet, demonstrating the value of restoration is a key to sustaining future public investment, especially in light of uncertainty of future climate change effects. At the Nisqually River Delta, a restoration partnership between the U. S. Fish and Wildlife Service Nisqually National Wildlife Refuge (Refuge), the Nisqually Indian Tribe (Tribe), and Ducks Unlimited culminated in re-established tidal flow to 360 ha of historic floodplain …

Rewards, Challenges, Approaches And Solutions For Developing The Soos Creek Bioassessment Tmdl, Stephanie E. Brock, Dave Garland, Joan Nolan
Salish Sea Ecosystem Conference
The focus of this presentation is to outline the development of Washington State’s first bioassessment TMDL. Under section 303(d) of the Clean Water Act and supporting regulations (40 CFR 130.7), states are charged with developing a list of impaired and threatened waters requiring a Total Maximum Daily Load (TMDL). Impaired waters are those not meeting one or more of the applicable Water Quality Standards, including designated uses, narrative criteria and numeric criteria. If biological assessment indicates a waterbody is impaired, the waterbody is included on the state’s section 303(d) list and prioritized for TMDL development. The Soos Creek watershed has …

It also addresses the various public perceptions of climate change via Yale’s Global Warming’s Six Americas project. The …
Extreme Pco2 Variability In A Macrotidal Eelgrass Meadow Mediated By Tidal And Diurnal Cycles, Brooke Love, Colleen O'Brien, Douglas A. Bulthuis
Extreme Pco2 Variability In A Macrotidal Eelgrass Meadow Mediated By Tidal And Diurnal Cycles, Brooke Love, Colleen O'Brien, Douglas A. Bulthuis
Salish Sea Ecosystem Conference
It has been suggested that photosynthetic activity of macrophytes in coastal areas can decrease pCO2 and may provide areas of refuge for organisms sensitive to ocean acidification. To assess the effect of a large eel grass meadow on water chemistry, discreet samples were collected hourly over several 24 hour cycles in Padilla Bay, WA. Calculated pCO2 ranged from less than 100 ppm to greater than 700 ppm, often over the course of only a few hours. Aragonite saturation, DIC and pH were also highly variable. These data, weather station data and in-situ sensors(Padilla Bay National Estuarine Research Reserve) were used …
Genomic Approaches To Assessing Ecosystem Health, Steven (Steven Beyer) Roberts
Genomic Approaches To Assessing Ecosystem Health, Steven (Steven Beyer) Roberts
Salish Sea Ecosystem Conference
Shellfish are an important component of our ecosystems. As sessile filter feeders, shellfish offer a valuable resource for revealing how the nearshore can be negatively influenced by anthropogenic activity and natural processes. Research in our lab focuses on using transcriptomic approaches to interrogate physiological responses, which in turn provides important insight into environmental conditions. Several projects will be presented including lab-based trials as well as efforts to characterize natural oyster populations in Puget Sound. More recently we have developed global epigenetic and proteomic approaches that could provide new insight into contaminant exposure and physiological impact. The potential for epigenetic approaches …

Protectiveness Of Aquatic Life Criteria For Copper Against Olfactory And Behavioral Effects In Freshwater And Saltwater Fish, David Deforest, Joseph S. Meyer, Robert W. Gensemer, Joseph W. Gorsuch, Burt Shephard, Jeanmarie Zodrow, William Adams
Salish Sea Ecosystem Conference
Stormwater runoff can result in episodic increases of copper concentrations in receiving waters of the Salish Sea basin. Based on several laboratory studies demonstrating that short-term exposures to low copper concentrations can cause olfactory and behavioral effects in Pacific salmon and trout, there is concern that these short-term increases in copper concentrations during storm events could be adversely impacting salmon and trout populations. For example, copper-induced olfactory impairment could potentially reduce the ability of juvenile salmon to avoid predators. Although behavior and olfactory impairment are more sensitive endpoints than the acute lethality endpoint commonly used for evaluating short-term exposures to …
Washington State Department Of Ecology: Biological Assessment Model Development And Use In State Regulatory Programs, Chad Brown, Chad Larson
Washington State Department Of Ecology: Biological Assessment Model Development And Use In State Regulatory Programs, Chad Brown, Chad Larson
Salish Sea Ecosystem Conference
The focus of this presentation is to summarize the Department of Ecology’s collection, model development, and regulatory use of macroinvertebrate community data. Surface water quality standards for the State of Washington are developed and enforced by the Department of Ecology. These rules to protect state waters are expressed as numeric and narrative criteria in Washington Administrative Code 173-201A. Monitoring data and information are compared to these criteria to determine compliance with the standards. Water column monitoring data for numeric pollutant criteria do not always provide sufficient information alone to detect water quality problems that may be related to a combination …

Spatio-Temporal Dynamics Of Marbled Murrelet Hotspots During Nesting In Nearshore Waters Along The Washington To California Coast, Martin G. (Martin George) Raphael, Andrew Shirk, Gary A. (Gary Anthony) Falxa, Scott F. Pearson, Craig S. Strong
Salish Sea Ecosystem Conference
The Marbled Murrelet, Brachyramphus marmoratus, is a federally listed alcid that forages in nearshore waters of the Pacific Northwest, and nests in adjacent older-forest conifers within 40-80 km of shore. To estimate abundance and distribution of murrelets, we conduct at-sea surveys from May to July each year, starting in 2000 and continuing to present. We record numbers of individuals sighted by using distance-based transects and compute annual estimates of density after adjusting for detectability. At-sea transects are subdivided into 5-km segments, and we summarized mean and variance of density at each segment in Puget Sound and along the coast from …

$Aving With Fish, Floodplains & Farmers: Expanding The Reach, Jeffery E. Mcgowan, Lauren Rich
Salish Sea Ecosystem Conference
Since 1955, Skagit County has been involved in flooding and sediment issues concerning Hansen Creek. Some form of sediment removal has been the response to localized flooding in the lower portion of the Hansen Creek Watershed. In 1982, at the request of flooded landowners, a Sub-Flood Control Zone was formed. Skagit County will present data on the costs of maintenance dredging and responding to emergency flooding over the 1997-2007 10-year period and also savings to both the County and landowners from the time when the floodplain project was implemented. Since the completion of the Hansen Creek Alluvial fan project in …

Adding Texture And Relief To Seattle’S New Seawall, An Application Of Ecological Engineering, Jeffery R. Cordell, Jason David Toft
Salish Sea Ecosystem Conference
The aftermath of the 2001 Nisqually earthquake revealed that Seattle’s seawall was decaying and in need of replacement. The resulting seawall replacement project presented an opportunity to replace vertical featureless walls with more complex and productive habitat. Several years before the new seawall was designed, the City of Seattle invited University of Washington biologists to participate in developing concepts for improved seawall habitat. This resulted in collaborations with several City of Seattle departments, during which we designed, deployed, and evaluated large habitat panels that tested several types of slopes and textures. Four years of monitoring algae, sessile invertebrates, and epibenthic …
