Sea Level Change In The Gulf Islands National Park Reserve, Southern British Columbia: Implications For The Interpretation Of Nearshore Archaeological Features, Glenda J. Wyatt

Salish Sea Ecosystem Conference

Sea level along the B.C. coastline has changed dramatically over the past 10,000 years due to isostatic rebound following deglaciation from the Fra ser Glaciation (Clague & James, 2002). In the future, sea levels globally are also predicted to rise according to the Intergovernmental Panel on Climate Change (IPCC) (2014), due to climate change. Lemmen et al. (2008), suggest that in the near future some B.C. coastal communities will have to deal with changes in shorelines due to rising sea levels, and hence erosional patterns, modifications to ecosystems and habitats, and potentially an altered marine food supply. This thesis examines …

Pacific Great Blue Heron Population Monitoring On Vancouver Island And The Surrounding Gulf Islands, Trudy A. Chatwin, Travis Heckford

Salish Sea Ecosystem Conference

The Pacific or Great Blue Heron fannini subspecies winters and breeds on Vancouver Island in locations within 5 km of the marine shoreline. Its visibility and close connection to the Salish Sea make it an important flagship species. Due to population concerns and threats associated with urban development, the Province of BC has coordinated monitoring of Great Blue Heron colonies on Vancouver Island and the adjacent Gulf Islands from 1997 through 2015. Starting in 2005, I trained volunteer stewards and technicians to use a standardized methodology to locate and assess heron colonies, count active nests, determine nest success and follow …

Bivalve Comparison Study At Clayton Beach From 1912 To Recent, Stephanie Yong

Scholars Week

The purpose of the bivalve comparison study is to examine changes in the bivalve populations at Clayton Beach between 1912 and the present. Sea floor material off the coast of Clayton Beach was collected to create a railroad bed for the Bellingham and Skagit Interurban Railway in 1912 by a dredge ship. The dredged material contains well-preserved shells that represent an unbiased bulk sample of the benthic molluscan fauna in Samish Bay prior to 1912. Clayton Beach provides a unique opportunity to examine species diversity, population numbers, and size frequency of the whole bivalve fauna from a particular point in …

Variation In Desiccation Resistance Between Different Rhagoletis Zephyria Populations Spanning The Cascade Mountains, Keely Hausken, Neal Shaffer, Jennifer Hill

Scholars Week

Local adaptation to environmental gradients can be an important source of variation that allows populations to evolve in response to environmental challenges. The snowberry maggot fly (Rhagoletis zephyria) is found throughout the different climate regions of Washington state. However, populations vary in their resistance to desiccation as an early pupa. We found that in low humidity treatments, desiccation resistance is predicted by annual precipitation and elevation and is tightly correlated with fly emergence the following season. Our results suggest that the variation in desiccation resistance in of R. zephyria is adaptive. Rhagoletis zephyria hybridizes with the agriculturally important invasive apple …

Roles Of Ubiquitin And Stress In Diacetyl Chemosensation Of C. Elegans, Ellen Zocher, Nelson Ruth, Marissa Hogg

Scholars Week

Ubiquitin is a small protein that can be attached to other proteins in a cell, tagging them for destruction. The process of adding ubiquitin to a protein substrate (ubiquitination), and the subsequent trafficking and degradation of this substrate, is a principle regulator of the abundance and activity of many proteins across all forms of life. We are examining the role and dynamics of this regulatory system in the olfactory neurons of the model organism Caenorhabditis elegans, specifically the olfactory receptor protein ODR-10, which allows the worm to detect diacetyl, a volatile compound that is produced by the bacteria the worm …

Calculating The Predictability Of Climate Change: The Effect Of Climate Change On Moth Species In The Pacific Northwest Varies Among Functional Groups., Julie Maurer

Scholars Week

Climate change has driven shifts in phenology and distribution for many species. These effects are often idiosyncratic and it remains unclear whether they vary consistently among functional groups, limiting our ability to draw broad conclusions about how climate change affects species. Previous studies have indicated that Lepidoptera (butterflies and moths) are sensitive to climate change. We analyzed a large database of moth specimen records from the Pacific Northwest (PNW) to examine climate change responses over more than 100 years for a suite of 241 functionally diverse species, including spring and fall active species as well as dietary generalists and specialists. …

Regulation Of Ampa-Type Glutamate Receptor Homolog Glr-1 By Erad Ubiquitin Ligases In C. Elegans, Sam Witus

Scholars Week

Endoplasmic reticulum-associated degradation (ERAD) maintains cellular health by removing misfolded proteins from the endoplasmic reticulum (ER). ERAD is ubiquitin-dependent, and ubiquitination of target proteins can be catalyzed by ER-resident E3 ubiquitin ligases. In C. elegans, genes for three putative ERAD E3 ubiquitin ligases have been identified: hrd-1, hrdl-1, and marc-6 (HRD-1, GP78/AMFR, and MARCH-6 in mammalian systems). In C. elegans, these three genes cooperate to maintain the overall health of animals during ER stress. We are testing the roles of hrd-1, hrdl-1, and marc-6 in the neurons of C. elegans. GLR-1 is a glutamate receptor that is expressed in a …

Movements Of Sub-Adult Chinook Salmon (Oncorhynchus Tshawytscha) In Puget Sound, Washington, As Indicated By Hydroacoustic Tracking, Anna Kagley, Joseph Smith, Kurt L. Fresh, Kinsey Frick, Thomas P. (Thomas Peter) Quinn

Salish Sea Ecosystem Conference

Alternative forms of migratory behavior can have substantial consequences for the growth, survival, and fitness of the individuals involved. Salmonids vary in the tendency of individuals to migrate to marine waters (anadromy) or remain in freshwater habitats. In addition, substantial variation in migratory patterns can exist among anadromous and resident species. This talk summarizes our use of hydroacoustic telemetry to investigate the movement patterns of anadromous Chinook salmon Oncorhynchus tshawytscha remaining in the marine waters of Puget Sound after ocean entry rather than continuing out to the coastal waters of the North Pacific Ocean, as is typical of the species. …

2015 Olympia Oyster, Ostrea Lurida, Brooding Results From Northern Puget Sound, Jackie E. Dexter, Sarah K. Grossman, Courtney M. Greiner, Julie S. Barber, James T. Mcardle

Salish Sea Ecosystem Conference

The Swinomish Indian Tribal Community recently began a restoration project to establish, expand, and research Olympia oyster, Ostrea lurida, populations on reservation tidelands. For our pilot project, we evenly distributed seeded cultch in two pocket estuaries in Similk and northern Skagit Bays during the summer of 2012 and spring of 2013. Subsequently, we initiated a long-term monitoring program that included measuring reproductive benchmarks to determine population expansion potential. While brooding data have been collected at one other site in northern Puget Sound (i.e. Fidalgo Bay), it is likely that oysters in pocket estuaries will be exposed to different environmental …

Problem To Progress: Understanding And Improving Permitting For Shoreline Armoring In Kitsap County, Kathlene Barnhart

Salish Sea Ecosystem Conference

Kitsap County partnered with San Juan County and the Washington Department of Fish and Wildlife to objectively review and assess the effectiveness of existing marine shoreline stabilization permitting programs in achieving a balance between applicant needs and protection of nearshore resources. Utilizing a T.A.C.T. approach (Troubleshooting, Action planning, Course correction and Tracking & monitoring), the agencies worked together to identify gaps and overlap in the permit review and monitoring process, as well as the effectiveness of permit provisions (conditions) through field assessment of recent marine shoreline armoring projects. Actions to correct these internal deficiencies and …

Cross-Border Citizen Action: Protecting The Salish Sea From The Risks Of Fossil Fuel Transport, Alexandra L. Woodsworth

Salish Sea Ecosystem Conference

Currently, more than a dozen oil, coal and liquid natural gas projects are proposed on both sides of the border, threatening the health of the Salish Sea and its communities, as well as the global climate. Recent estimates suggest that if all the projects were to be approved, each year they would generate an extra 308 million tonnes of carbon dioxide emissions and an additional 1,200 ship journeys through the already-busy waters of the Salish Sea. Each fossil fuel project proposed in BC and Washington is currently being assessed in isolation from the others by the government agencies that are …

Relative Abundance Of Sixgill Sharks (Hexanchus Griseus) In Elliott Bay, Seattle, Washington, Denise Griffing, Shawn Larson, Jeff Christiansen, Joel Hollander, Tim Carpenter

Salish Sea Ecosystem Conference

The Sixgill Shark Research Project is designed to address gaps in the body of scientific knowledge on bluntnose sixgill sharks (Hexanchus griseus) in Puget Sound. This project utilizes three interwoven techniques: (1) genetics research, (2) visual marker tagging, and (3) video analysis. Seattle Aquarium biologists monitor sixgill shark sightings reported by local divers (since 1999) and study their relative abundance in Elliott Bay under the Aquarium’s pier (since 2003). Here we report on our findings of relative abundance.

Bluntnose sixgills are a species of conservation concern. Sixgills are listed as “near threatened” on the IUCN Red List. Living mainly at …

Simulating The Dispersal Of Invasive Clams In A Freshwater Lake Using A Three-Dimensional Hydrodynamic Model; A Prototype For Simulating Invasions In Marine Ecosystems, Elizabeth Kilanowski, Lambert Rubash

Salish Sea Ecosystem Conference

The discovery of several populations of an invasive Asian clam (corbicula fluminea) in Lake Whatcom, the drinking water source for approximately 100,000 people in Northern Washington State, created a need among elected officials, local government staff, and the public for a better understanding of lake hydrodynamics during the reproductive season for the Asian clam, and for times when Quagga and Zebra mussel invasions are likely. Seasonal vertical thermal stratification of the lake and a desire to predict likely locations of additional clam populations or of new populations of mussels led to the choice of a model that could be configured …

Protecting Puget Sound From Csos By Retrofitting Urban Neighborhoods With Green Stormwater Infrastructure, Kathryn Gwilym Pe, John Phillips, Steve Burke Pe, Peg Staeheli Fasla

Salish Sea Ecosystem Conference

In 2009 King County Wastewater Treatment Division (KCWTD) selected green stormwater infrastructure (GSI) as the preferred alternative for controlling combined sewer overflows (CSO) for the 1100-acre Barton combined sewer system (CSS) basin in Seattle. In 2008 KCWTD reported that the basin had an average of four overflows per year that discharge a total of four million gallons into Puget Sound. In order to reduce the overflows to no more than one CSO event per year for Washington State’s Department of Ecology compliance, KCWTD retrofitted 15 residential streets with bioretention cells in order to intercept, treat and reduce the amount of …

A Nonparametric Statistical Approach To Analyzing Eelgrass Density Data, Traci L. Sanderson, Michelle Spani, Andrew Rippington

Salish Sea Ecosystem Conference

As part of continuing work in Port Gamble, WA a diver-based eelgrass survey was completed to support the application for a Hydraulic Project Approval (HPA), as required by the Washington State Department of Fish and Wildlife (WDFW) for in-water work. The survey was completed following interim guidelines established by WDFW in 2008, although to fit the guidelines to the specific project some methods were modified and approved by WDFW. Collecting statistically robust data proved to be difficult, as shoot density in the eelgrass bed was highly variable. In some areas the variance was so high that power calculations estimated the …

MacIlroy Consulting, Inc. and Environmental Science Associates (ESA) collaborated to develop data visualization and communication tools for the Skagit Climate Science …

Assessing Habitat Compensation In The Lower Fraser River And Estuary, Megan A. Lievesley, Dan Stewart, Brad Mason, Rob Knight

Salish Sea Ecosystem Conference

Over the last century, wetland ecosystems along the Lower Fraser River (LFR) have been heavily impacted by foreshore development and industry. Wetlands along the LFR provide important ecosystem services and habitat for wildlife such as rearing grounds for fish and staging grounds for migratory birds. For 30 years, habitat compensation has been the accepted method for offsetting habitat degradation; however, due to a lack of follow-up research and consistent baseline data it is yet to be determined if compensation projects truly replicate habitat lost. This project, funded by the National Wetland Conservation Fund, aims to (1) review, assess, and determine …

Greening Real Estate Professionals: A Model For Landowner Engagement Through Effective Education For Brokers & Appraisers, Erica S. Guttman, Robert C. Simmons

Salish Sea Ecosystem Conference

Real estate brokers, appraisers, and developers are an essential audience for bridging communication with new landowners throughout the Salish Sea watershed. The majority of these professionals share concerns about protecting water quality, ensuring the health of theSalishSeafor recreation and economic vitality, and preventing activities that lead to anthropogenic-caused landslides, flooding and other disasters.

Since 1998, WSU Extension has managed a real estate school focused on "green" topics to engage real estate professionals in these issues critical to their clients and our region's water resources. In recent years, our focus has centered on the topics of Green Stormwater Infrastructure and Understanding …

A Framework To Assess Vulnerability Of Biological Components To Ship-Source Oil Spills In The Marine Environment, Kate Thornborough, Candice St. Germain, Lucie Hannah, Miriam O

Salish Sea Ecosystem Conference

A structured approach to identify biological components most affected by a ship-source oil spill has been developed utilising a suite of criteria to assess vulnerability. Our approach divides criteria into three categories: exposure, sensitivity, and recovery, each encompassing a number of criteria which are envisaged to be consistent and broad enough to be usable in any region in Canada. In support of this, we are working with biologists from other Canadian regions who are currently developing ship-source oil spill response plans (i.e. Pacific, Quebec and Maritimes) to test the usability of this approach in multiple marine environments. For the Pacific …

Variable Marsh Resilience To Stress Offers Clues To Climate Change Adaptive Management, Roger Nathan Fuller, Katrina L. Poppe, John M. Rybczyk, Eric Grossman, Chad Stellern

Salish Sea Ecosystem Conference

In Puget Sound’s Stillaguamish estuary, tidal marshes exhibit evidence of multiple stressors that affect their vulnerability and provide insight into adaptive management opportunities to enhance their resilience. Despite high accretion rates, some marsh areas have receded by 10m/yr since 1964. Sources of stress include overgrazing by snow geese, high soil salinities, insect attacks, and changes in flow and inundation patterns. These interact with winter vegetation structure, sediment composition, and wave exposure to result in spatially variable marsh resilience. Some marshes are receding quickly, some slowly, and others are minimally affected. In the context of climate change, with potentially substantial near-term …

Mapping On The Edge: Shoreline Mapping For Regulation And Voluntary Stewardship, Kate E. Emmings

Salish Sea Ecosystem Conference

Nothing generates conversations between landowners and local government like a map! Shoreline mapping is a crucial decision making tool for local governments and regulators. It provides information about appropriate location of shoreline infrastructure, such as docks, and informs landowners about the location of important natural transition areas between the land and the sea. Maps can also provide information that limits the activities of private landowners and as such can cause community conflict if they are inaccurate or unclear. Because mapping can be used to inform regulation, local governments often have different needs than scientists and NGOs, but there is no …

Armoring On Puget Sound: Progress Towards A Better Baseline, Hugh Shipman, Jennifer Burke, Randy E. Carman, Kurt L. Fresh

Salish Sea Ecosystem Conference

The construction of seawalls and similar structures along Puget Sound’s shoreline impacts geomorphic processes and ecological functions. The extent of shoreline armor has been adopted by the Puget Sound Partnership as a vital sign indicator, is used by local, state, and federal groups as a measure of ecosystem function, and has been employed as a tool for prioritizing restoration actions.

As a result, we recognized the importance of accurately characterizing the extent, character, and distribution of shoreline armor. The objectives of our project were to review existing data sources, assess methodologies, identify gaps in data quality or coverage, and to …

Resources For Marine Shoreline Design, Theresa Mitchell

Salish Sea Ecosystem Conference

Shoreline armoring and reducing the use of hard, structural approaches to protecting property is a hot topic across marine communities of North America. As we learn more about the importance of the marine and terrestrial interface (the nearshore zone), we also understand more about how our past practices of hard armoring shorelines can be problematic to the nearshore zone and the ecosystem goods and services it provides. Shifting property owners away from using common hard approaches to erosion protection is difficult to achieve without easy access to information on effective environmentally-friendly alternatives.

The Washington Department of Fish and Wildlife and …

From The Ivory Tower Through The Black Box: Engaging Effectively With Government To Turn Ideas Into Action, Gabriel Mastico

Salish Sea Ecosystem Conference

When researchers, communities, and/or environmental organizations propose new approaches to address ecological challenges, responsibility for implementing them often falls (in part) to practitioners working within government. Government employees face considerable challenges in synthesizing the available knowledge to support a recommendation for decision-makers to adopt a new approach. This presentation draws on an insider’s experience to help conservation researchers and practitioners understand the key challenges and opportunities that government employees face in navigating their organizations’ decision-making processes. It also suggests best practices to help proponents of new approaches frame conservation finance ideas in ways that resonate with local governments and their …

An Inventory Of Environmental Governance In The Salish Sea, Laurie D. Trautman

Salish Sea Ecosystem Conference

How is the natural environment of the Salish Sea governed? The fact that the Salish Sea is bifurcated by a national border has inhibited our ability to answer this question. Indeed, the Salish Sea involves not only two national governments, but also a multitude of both state and non-state actors, which exist across scales, and interact in different frameworks (i.e. First Nations/tribes often seek only to negotiate with federal, rather than state/provincial governments). Environmental governance in the Salish Sea also encompasses informal modes of interaction involving public and private interest groups, social movements and community stakeholders, in addition to traditional …

Synthesis Of Results From Twelve Puget Sound Regulatory Effectiveness And Incentive Investigations, Aimee Kinney, Tessa B. Francis, Jeff Rice

Salish Sea Ecosystem Conference

Between 2011 and 2014, the Puget Sound Marine and Nearshore Grant Program funded twelve projects relating to shoreline regulatory and incentive programs. Here we provide an overview of overarching themes that emerged from a review of the projects in aggregate. Despite the different approaches to problem identification, data collection, and analysis in these investigations, the conclusions reached and recommendations made are remarkably similar. Key findings and implications of our analysis relate to: (1) armoring compliance rates; (2) compliance monitoring methodologies; (3) local Shoreline Master Program (SMP) capacity limitations; (4) SMP implementation improvements; and (5) incentive programs to encourage the use …

Developing Locally-Driven (Shoreline) Monitoring Programs In The Salish Sea (And Beyond), David Sale

Salish Sea Ecosystem Conference

During the development of the Bainbridge Island Shoreline Monitoring Program (SMP), a volunteer group of scientists and engineers (Bainbridge Island Environmental Technical Advisory (ETAC)), provided the City of Bainbridge Island (COBI) City Council and staff with advice and recommendations on relevant shoreline science and the SMP. One of the recommendations was for COBI to adopt and initiate a locally–driven and -managed monitoring program to address both the effectiveness of the SMP over time, and uncertainties in knowledge of specific Bainbridge Island shoreline drivers and processes. The program would be designed to integrate past and current studies by COBI and other …

Reducing Uncertainties In Managing In British Columbia Waters: Applying An Adaptive Management Mindset On The South, Central And North Coasts, Erica Olson, Carol Murray, Natascia Tamburello

Salish Sea Ecosystem Conference

British Columbia’s vast coastline is characterized by ecologically rich, rugged, and remote regions where there are many uncertainties about the way that ecosystems function. This translates into a challenge for environmental managers, as it creates considerable uncertainty about which management actions will be most effective for achieving management goals and objectives. Adaptive management can offer a way forward by providing systematic, rigorous approach for designing and implementing management actions to maximize learning about critical uncertainties affecting decisions on environmental management policy and practice. It typically follows a six-step cycle focusing on the implementation and monitoring of management actions that are …
