What Early Life History Tells Us About Restoration Success In Olympia Oysters, Bonnie Becker, Michael Behrens
What Early Life History Tells Us About Restoration Success In Olympia Oysters, Bonnie Becker, Michael Behrens
Salish Sea Ecosystem Conference
Native Olympia oysters have been the subject of widespread restoration efforts across the west coast, including in the Salish Sea. The ultimate goal of restoration is to establish populations that are self-sustaining or even exporting new offspring to other appropriate habitats. It is difficult to study the early life history of marine invertebrates, which have a microscopic and planktonic larval form and often episodic settlement pulses. However, being able to predict larval behaviors and settlement preferences can allow practitioners to design habitats, choose sites, and distribute restoration networks more effectively. The purpose of this study, a collaboration among academic and …
Shellfish At Work: Nutrient Bioextraction Demonstration In South Puget Sound, Aimee Christy, Andrew Suhrbier, Bobbi Hudson
Shellfish At Work: Nutrient Bioextraction Demonstration In South Puget Sound, Aimee Christy, Andrew Suhrbier, Bobbi Hudson
Salish Sea Ecosystem Conference
This project explored the application of extractive aquaculture technologies using shellfish for nutrient mitigation in urban nearshore environments of Tacoma and Olympia, WA. Nutrient removal by shellfish, which are then harvested and removed from the system, has the potential to help address environmental issues such as excess inputs of nutrients (eutrophication), low dissolved oxygen, and reduced light availability. The research focus was to: 1) implement demonstration aquaculture systems; 2) determine nutrient removal services of mussels grown; 3) assess the feasibility of producing soil compost from the demonstration systems; and 4) increase local stakeholder awareness of and engagement in urban water …
Applying Ecosystem Services Analysis To The Shellfish Industry, Marlene Meaders
Applying Ecosystem Services Analysis To The Shellfish Industry, Marlene Meaders
Salish Sea Ecosystem Conference
Shellfish provide numerous essential ecosystem services that are valuable to humans, including nutrient uptake, water filtration, and provision of habitat for aquatic organisms. Ecosystem services analysis can be a valuable tool for examination and management of shellfish, and can be used in combination with other activities on a landscape-level. One example would be the examination of cumulative impacts within specific inlets of Puget Sound, which is especially relevant to the shellfish industry. Cumulative impacts analysis is a way to determine future use of an area given a variety of management decisions and projected growth within a water body. For example, …
Retrofitting An Urban Watershed To Protect Shellfish Beds, Mindy Fohn, Chris May
Retrofitting An Urban Watershed To Protect Shellfish Beds, Mindy Fohn, Chris May
Salish Sea Ecosystem Conference
In the 1960's shell fishing was abandoned in Dyes Inlet due to ongoing fecal pollution problems. In 1994 a stable and ongoing water quality monitoring program was established and identified polluted streams and near shore areas whereby a cooperative watershed effort resulted in numerous pollution correction projects. These efforts resulted in reclassification and upgrade of 1,500 acres of shellfish beds in 2003. However, polluted stormwater from the urban area of Silverdale has the potential to threaten the shellfish beds. Polluted stormwater was reduced by removing non-stormwater discharges from dumpster areas, enhancing road right of way storm system maintenance and working …

Salish Sea Ecosystem Conference
The risk of oil spills from existing oil infrastructure and transport presents a threat to aboriginal environmental and cultural values. First Nations can play a significant role in oil spill response to protect those resources. In this presentation, the authors summarize the Tsleil-Waututh Nation’s involvement in this area and provide recommendations for developing capacity and maximizing effectiveness of First Nations’ participation in oil spill prevention, preparedness, response and recovery. Prevention: First Nations should have the opportunity for consultation with provincial and federal regulatory agencies to ensure standards are adopted that reduce to the maximum extent possible the risk of spill …
Assessing Water Treatment Residuals As A Filtration Media For Phosphorus Removal At Wapato Lake - Tacoma, Wa, Brian Hite, Megan Hintz
Assessing Water Treatment Residuals As A Filtration Media For Phosphorus Removal At Wapato Lake - Tacoma, Wa, Brian Hite, Megan Hintz
Salish Sea Ecosystem Conference
Wapato Lake in Tacoma, WA is a 23-acre urban lake that has had problems of eutrophication and toxic algae blooms for over a hundred years. Inputs of phosphorus from both environmental and anthropogenic sources contribute to this problem. Much of the 900-acre watershed consists of residential or commercial development, increasing the amount of stormwater containing increased levels of phosphorus. Past management efforts designed to control eutrophication at Wapato included constructing a diversion structure to route phosphorus rich stormwater around the lake. This plan increased the retention time of Wapato to ≈ 8.5 years. We have been tasked by the City …

The map depicts over 36,000 individual change events covering over 85,000 acres throughout the …
Human Dimensions Of Puget Sound Ecosystem Health And Recovery: Social Sciences Scale And Scope, Mary Rozance, Kathleen Wolf
Human Dimensions Of Puget Sound Ecosystem Health And Recovery: Social Sciences Scale And Scope, Mary Rozance, Kathleen Wolf
Salish Sea Ecosystem Conference
The Puget Sound Basin is surrounded by human settlements that range from small resource-dependent communities, to metropolitan areas that are experiencing rapid population growth. Scientific studies in the biophysical disciplines have documented the Puget Sound's ecological decline, established baseline conditions for recovery, and identified human-based sources of ecosystem impacts. The Puget Sound region is a complex socio-ecological system thus making equal attention to human dimensions an important goal, even a necessity. Social scientists across a variety of disciplines (such as economics, geography, anthropology, sociology, and psychology) can contribute to large-scale ecosystem health and recovery in two general ways. First, studies …
Nine Years Of Rockfish Surveys In The Strait Of Juan De Fuca, Shawn Larson, Jeff Christiansen
Nine Years Of Rockfish Surveys In The Strait Of Juan De Fuca, Shawn Larson, Jeff Christiansen
Salish Sea Ecosystem Conference
For decades, biologists from the Seattle Aquarium have been informally monitoring bottom fish on rocky reefs in Neah Bay, Washington. Based on increasing concern over the long term stability of bottom fish populations in this area by both state and federal agencies, the Aquarium formalized monitoring in 2005 with diver-based video surveys to quantify bottom fish (rockfish and lingcod) diversity and abundance over time. Divers performed 100-meter video transects, devised to be non-invasive and repeatable, to assess diurnally active and relatively sessile bottom fishes over time. Transects were conducted in the Strait of Juan de Fuca each year in August …

Salish Sea Ecosystem Conference
Empirical data on recruitment and dispersal patterns of marine species can provide a scientific basis for conserving biodiversity and improving fisheries via marine reserves. We examined patterns of larval dispersal in brown rockfish (Sebastes auriculatus) using genetic markers (microsatellites). Tissue samples from 1,837 fish were collected in 2004 to 2009 from 18 sites in the Puget Sound, Washington. Genetic parentage analysis using maximum-likelihood and exclusion approaches identified seven offspring that assigned to a parent, with one offspring assigned to both parents. All offspring recruited and settled at the main study site, Point Heyer; four offspring originated from parents resident at …
Reducing Disaster Vulnerability Of Coastal Communities On The Salish Sea, Stephanie Chang
Reducing Disaster Vulnerability Of Coastal Communities On The Salish Sea, Stephanie Chang
Salish Sea Ecosystem Conference
This paper provides an overview of the disaster vulnerability of coastal communities on the Salish Sea. In addition to natural hazards such as earthquakes, tsunamis, and floods (both riverine and coastal), coastal communities in this region are at risk from human-induced and technological disasters such as oil spills and terrorism threats. Vulnerability – or the propensity to suffer loss when a hazard event occurs – is affected by many factors related to geographic setting, the built environment, economic conditions, socio-demographics characteristics, and institutional context. In a case study of Metro Vancouver, this paper identifies and compares key vulnerability factors in …
Coastal Resilience For Habitats And Humans: Integrating Green And Grey Infrastructure Solutions, Roger Nathan Fuller, Eric Grossman
Coastal Resilience For Habitats And Humans: Integrating Green And Grey Infrastructure Solutions, Roger Nathan Fuller, Eric Grossman
Salish Sea Ecosystem Conference
Communities are protected from floods and storms by both engineered infrastructure like levees, and natural habitat infrastructure like wetlands. We understand the performance and cost effectiveness of engineered or grey infrastructure well. However, recent natural disasters have illustrated both their insufficiency in protecting communities and the high repair costs. We know that green infrastructure, or natural habitats, also protect communities from river floods and coastal storms but we know little about their performance and cost. This knowledge gap leads to greater investment in grey at the expense of green. In addition, green infrastructure provide other benefits to human communities, and …

Multiple Stressors On The Potential Toxicity Of Heterosigma Akashiwo, A Fish-Killing Flagellate In The Salish Sea., Julia Matheson, William Cochlan, Charles Trick
Salish Sea Ecosystem Conference
As a large, island rich, estuary, the Salish Sea is strongly influenced by a diversity of ocean water intrusions and by direct and indirect human activities. The consequences of these processes provide multiple stressors on incumbent species, such as the potentially economically damaging blooms of the fish-killing flagellate Heterosigma akashiwo. Here we present laboratory findings on the combination of increased ocean acidification (pH) and modified nutrient supply (N:P) on the toxicity of a Puget Sound isolate from the Salish Sea. The toxicity and growth responses of batch cultures, conducted at a range of initial concentrations of nitrate and phosphate (N:P …

Brandenberger, Maggie Dutch, Joan Hardy, Christopher Andrew James, Deb Lester, April Markiewicz, Dale Norton, Sandra M. O'Neill, Brian Penttila, Heather Trim, Irvin Schultz, James West, Kathleen Conn, Alec Maule
Salish Sea Ecosystem Conference
We are now approaching a tipping point where priority pollutants may no longer be the primary driver of environmental impairment. Contaminants of Emerging Concern (CECs) present a challenge to environmental monitoring and management programs because the rapidly emerging state of the knowledge requires an adaptive and transparent prioritization framework. The state of the science, treatment technologies, and regulatory policies are not well understood, CEC quantification is challenging and expensive, and the management approach is not simply a concentration based criteria, but may include biological end-points. The need for a shared responsibility and leveraging across many programs was evaluated through a …

What Goes Down The Drain Eventually Reaches The River: Characterizing Contaminants Of Emerging Concern (Cecs) In The Columbia River Basin, Jennifer Morace, Elena Nilsen
Salish Sea Ecosystem Conference
Toxic contamination is a significant concern in the Columbia River Basin in Washington and Oregon. To help water managers and policy makers in decision making about future sampling efforts and toxic-reduction activities, the USGS did a reconnaissance to assess contaminant concentrations contributed directly to the Columbia River through wastewater-treatment-plant (WWTP) effluent and stormwater runoff from adjacent urban environments, as well as to evaluate instantaneous loadings to the Columbia River Basin from these inputs. Nine cities were selected in Oregon and Washington to provide diversity in physical setting, climate characteristics, and population density. Samples were collected from a WWTP in each …
Monitoring The Movements Of A Critical Marine Resource: Tracking A Forage Fish In Puget Sound, Theresa Liedtke, Ryan Tomka, Collin Smith, Lisa Gee, Dennis Rondorf
Monitoring The Movements Of A Critical Marine Resource: Tracking A Forage Fish In Puget Sound, Theresa Liedtke, Ryan Tomka, Collin Smith, Lisa Gee, Dennis Rondorf
Salish Sea Ecosystem Conference
Forage fish are small, schooling, pelagic fish that form a critical link in marine food webs between plankton and larger fish, marine mammals, and seabirds. In Puget Sound, the forage fish assemblage includes Pacific herring, Pacific sand lance, surf smelt, and northern anchovy. There are significant information gaps on basic life history, distribution, movements, and stock abundances for these species, making management of this resource challenging. To begin addressing some of these gaps, we initiated a study of the movements of surf smelt during their spawning period in November 2012. We captured fish near a well-documented spawning beach in Sinclair …
Variation In Juvenile Chinook Salmon Diet Composition And Foraging Success Between Two Estuaries With Contrasting Land-Use Histories, Aaron David, Charles Simenstad, Jeffrey R. Cordell, Jason David Toft, Christopher Ellings, Ayesha Gray, Hans B. Berge
Variation In Juvenile Chinook Salmon Diet Composition And Foraging Success Between Two Estuaries With Contrasting Land-Use Histories, Aaron David, Charles Simenstad, Jeffrey R. Cordell, Jason David Toft, Christopher Ellings, Ayesha Gray, Hans B. Berge
Salish Sea Ecosystem Conference
The transition of juveniles from fresh water to estuarine and marine environments is a critical period in the life cycle of Pacific salmon, during which survival can be strongly size-selective. Because the amount and quality of food consumed are major determinants of juvenile salmon growth, successful acquisition of energy rich prey during estuarine residence is critical for survival. Humans have likely impacted the feeding relationships of juvenile salmon in estuaries by destroying estuarine wetlands and by altering the abundance of salmon in estuaries. While the estuarine foraging habits of juvenile salmon have been extensively examined, few studies have conducted quantitative …

Observations On Abundance Of Bluntnose Sixgill Sharks, Hexanchus Griseus, In An Urban Waterway In The Salish Sea, 2003-2012, Shawn Larson, Denise Griffing, Jeff Christiansen, Joel Hollander, Tim Carpenter
Salish Sea Ecosystem Conference
The bluntnose sixgill shark, Hexanchus griseus, is a widely distributed but poorly understood large, apex predator. Anecdotal reports of diver-shark encounters in the late 1990’s and early 2000’s in the Pacific Northwest stimulated interest in the normally deep-dwelling shark and the reason for its presence in the shallow waters of the Salish Sea. Analysis of underwater video documenting sharks at the Seattle Aquarium’s sixgill research site on Seattle’s waterfront and mark-recapture techniques were used to identify individual sharks to answer simple questions about abundance and seasonality. Temporal changes in relative abundance in Puget Sound were reported from a controlled study …
The Relationship Of Oak Gall Size To Lichen Proximity On Quercus Garryana, Garrett Noyd, Alex Nelson
The Relationship Of Oak Gall Size To Lichen Proximity On Quercus Garryana, Garrett Noyd, Alex Nelson
Salish Sea Ecosystem Conference
Oak galls are formed when a female gall wasp lays her eggs on the host plant. She then injects the host plant with a toxin that makes the plant form a tumor around her eggs, protecting them. Oak galls and lichen both use the same nutrients, resulting in competition for nutrition and space on a tree. Our data was collected at the Glacial Heritage Preserve in Thurston County, Washington. The purpose of this paper is to study the relationship between oak gall placement and the presence of lichen on twigs. We measured the diameter of an oak gall and then …
