Relational Values And Valuation: Challenges, And Possibilities, Kai Chan Apr 2018

Relational Values And Valuation: Challenges, And Possibilities, Kai Chan

Salish Sea Ecosystem Conference

Although the ecological valuation literature has been focused largely on instrumental values, there is increasing recognition that relational values might play a crucial and related role in environmental policy and practice. For example, relational values—as preferences, principles and virtues about human relationships involving nature—are identified as central in the IPBES Conceptual Framework, and recent work has investigated the implications of these for conservation and ecosystem management. But what are the implications of relational values for ecosystem valuation? In this talk, I address this question in three points. First, whereas instrumental or economic values are values of a thing ...


Wood Waste Assessment, Characterization, And Remediation In Esquimalt Harbour, Mikaela Davis, Scott Northrup Apr 2018

Wood Waste Assessment, Characterization, And Remediation In Esquimalt Harbour, Mikaela Davis, Scott Northrup

Salish Sea Ecosystem Conference

Log booming and wood processing operations in BC’s Esquimalt Harbour since the 1800s have resulted in the accumulation of wood waste deposits throughout the subtidal zone. Wood waste can adversely affect sediment quality and benthic and infaunal communities, prompting the Department of National Defence to prioritize the assessment of effects of wood waste on the ecological health of the nearshore marine environment in Esquimalt Harbour. In alignment with the overall Esquimalt Harbour Remediation Project, The Esquimalt Harbour Wood Waste Assessment and Characterization Project was initiated in 2016 and continues into 2018, with Hemmera supporting the assessment, determination of impacts ...

The presentation includes a report on protected species seen during the first year of both projects, and the use of ArcGIS Online Survey 123 for sightings data collection.


Discerning Population Connectivity And Natal Origins Of Pacific Herring (Clupea Pallasi): Inferences On Population Structure From Otolith Chemistry, Wade Smith, Tony Pitcher, Margot Hessing-Lewis, Brian P.V. Hunt, Evgeny A. Pakhomov Apr 2018

Discerning Population Connectivity And Natal Origins Of Pacific Herring (Clupea Pallasi): Inferences On Population Structure From Otolith Chemistry, Wade Smith, Tony Pitcher, Margot Hessing-Lewis, Brian P.V. Hunt, Evgeny A. Pakhomov

Salish Sea Ecosystem Conference

Pacific herring, Clupea pallasi, undertake annual migrations between feeding and spawning grounds that link life stages, habitats, populations, communities, and ecosystems. However, movement patterns of these highly mobile fish are poorly understood. Declines in Pacific herring abundance and slow population recoveries in the absence of fishing pressure have elevated concerns over the status of this ecologically, economically, and culturally important species. Pacific herring spawn on substrate in nearshore habitats where eggs and larvae develop for approximately two weeks before hatching. Early development within discrete spawning grounds could facilitate the incorporation of distinctive chemical signatures within otoliths that could be used ...


Understanding The Implications Of A Changing Environment On Harvested Bivalve Populations Using Habitat Suitability Models, Ted Dewitt, Nathaniel Lewis, Eric Fox, Stephen Pacella Apr 2018

Understanding The Implications Of A Changing Environment On Harvested Bivalve Populations Using Habitat Suitability Models, Ted Dewitt, Nathaniel Lewis, Eric Fox, Stephen Pacella

Salish Sea Ecosystem Conference

Habitat suitability models are useful to forecast how environmental change may affect the abundance or distribution of species of interest. In the case of harvested bivalves, those models may be used to estimate the vulnerability of this valued ecosystem good to stressors. Using literature-derived natural history information, rule-based habitat suitability models were constructed in a GIS for several bivalve species (Clinocardium nuttallii, Mya arenaria, and Tresus capax) that are recreationally and commercially harvested in NE Pacific estuaries, including in the Salish Sea. Spatially-explicit habitat maps were produced for two Oregon estuaries using environmental data (salinity, depth, sediment grain size, and ...


The Role Of Reproductive Timing As A Driver Of Genetic Differentiation In Populations Of Pacific Herring, Eleni L. Petrou, Todd Sandell, Dayv Lowry, Lorenz Hauser Apr 2018

The Role Of Reproductive Timing As A Driver Of Genetic Differentiation In Populations Of Pacific Herring, Eleni L. Petrou, Todd Sandell, Dayv Lowry, Lorenz Hauser

Salish Sea Ecosystem Conference

There is growing recognition that maintaining diversity in life history traits contributes to the sustainable management of wild populations. One important life history characteristic is reproductive phenology, and it has been shown that differences in the timing of reproduction can act as a barrier to gene flow between populations. If the difference in reproductive timing determines the level of connectivity, one would expect that genetic differentiation between populations would increase as a function of difference in reproductive date. This pattern, known as “isolation by time” (IBT), has been observed in wild populations of salmonids containing early and late runs. Pacific ...

Downstream Fish Passage Improvements At Hiram M. Chittenden Lock And Dam, Seattle, Wa: A New Approach For An Old Dam, Phil Peterson, Scott V. Pozarycki, Adam Slowik, Paul Heisey

Salish Sea Ecosystem Conference

The Salish Sea is ringed with human development and infrastructure of multiple generations, some of which strongly influenced patterns of early development and continue to this day to maintain significant elements of the human environment. These developments are not going away, we will not “preserve” our way out of the environmental challenges they pose. Thus, it remains the role of the scientists, engineers, and owners to collaboratively guide their modification and maintenance to make their operation and presence more benign to the fish and the environment. One such development is the US Army Corps of Engineers owned and operated Hiram ...

Ocean Networks Canada has operated Salish Sea CODAR high-frequency (HF) surface radar systems for monitoring surface currents since 2012. The network of antennae continues to grow, with four arrays now deployed in the southern Strait of Georgia, two more planned for the Strait of Juan de Fuca, and several more installed and planned along BC’s northern coast. These arrays provide hourly maps of surface currents. In the Strait of Georgia, where the Fraser River and ocean tides meet, there are complex surface current patterns that vary under seasonal river and wind conditions. Data are used to understand the circulation ...


Challenges And Opportunities For Marine Spatial Planning In The Salish Sea: Learning From Other Jurisdictions, Ross Jameson, Alexandra Barron, Sabine Jessen Apr 2018

Challenges And Opportunities For Marine Spatial Planning In The Salish Sea: Learning From Other Jurisdictions, Ross Jameson, Alexandra Barron, Sabine Jessen

Salish Sea Ecosystem Conference

The Salish Sea is a tremendously dynamic, diverse, and ecologically significant inland sea. It has supported indigenous communities for millennia and is now one of the most heavily used coastlines in the world. Increasing industrial use has resulted in declining biodiversity and ecosystem health. As we continue to see increases in human activities and escalating impacts from climate change on marine ecosystems, and associated declines in marine biodiversity and ecosystem health, Marine Spatial Planning (MSP) is becoming an increasingly important tool to ensure sustainable use of our coastal and marine resources, for generations to come. However, MSP is a resource ...


Effects Of Large Infrastructure On The Underwater Visual Environment And Heightened Predation On Salmon In The Salish Sea, David A. Beauchamp Apr 2018

Effects Of Large Infrastructure On The Underwater Visual Environment And Heightened Predation On Salmon In The Salish Sea, David A. Beauchamp

Salish Sea Ecosystem Conference

Most predatory fish, marine mammals, and birds that eat salmon rely primarily vision to feed. Natural processes and anthropogenic change affect visual conditions underwater which in turn profoundly affect the magnitude of predation risk on juvenile and adult salmon as well as forage fishes and other species in shoreline and pelagic environments. I will discuss the implications of how natural and anthropogenic changes in water transparency and artificial light pollution have significantly increased the predation threat environment for juvenile salmon in the Salish Sea and relate these to some of the major infrastructure projects in the Pacific Northwest. High levels ...

New Wood Waste Standard Operating Procedures For Canadian Disposal At Sea Program, Adam Larusic, Rebecca Seifert

Salish Sea Ecosystem Conference

Environment and Climate Change Canada’s Disposal at Sea Program regulates Disposal at Sea activities with the goal of preventing marine pollution. Most of the material that is disposed of at sea is dredged material that must be moved to keep shipping channels and harbors clear for navigation and commerce. In British Columbia dredged material sometimes contains wood waste as a by-product of the wood processing industry. This presentation will provide an overview of new wood waste operating procedures being proposed for the Disposal at Sea Program, based on recommendations from a report by Azimuth Consulting Group of Vancouver, BC.


Working On The Railroad: Coastal Streams Prioritization To Inform Restoration Planning, Paul Schlenger, Phil Bloch, Jennifer Griffiths Apr 2018

Working On The Railroad: Coastal Streams Prioritization To Inform Restoration Planning, Paul Schlenger, Phil Bloch, Jennifer Griffiths

Salish Sea Ecosystem Conference

Puget Sound’s nearshore has been substantially modified since the Industrial Revolution with extensive infrastructure developed along the shoreline. In Washington State, the BNSF railroad right-of-way runs along 52 miles of the shoreline, while another 73 miles of railroad is within 200 feet of the shoreline. In many places, the railroad forms a barrier between the coastal watershed and the shoreline preventing the delivery of water, sediment, wood and organic matter into the nearshore. This creates ongoing degradation of habitat quality in the nearshore, including small estuaries and coastal embayments, which provide important habitat to juvenile Chinook salmon. In addition ...

Salish Sea Ecosystem Conference

The majority of the Town of La Conner sits at an elevation (MLLW) of 8-13 feet where over the last number of years Town staff have gone from seeing the baseboards of their overwater business district being reached once or twice every four to five years to being reached four to five times a year. These high water events come at great expense to the Town and leave the Town regularly just shy of a major disaster. The Town of La Conner partnered with the Skagit Climate Science Consortium (including USGS, UW Climate Impacts Group and Western Washington University) and ...


When Fish Speak English, Heidi Siegelbaum Apr 2018

When Fish Speak English, Heidi Siegelbaum

Salish Sea Ecosystem Conference

“What did you just say?” This is the world where cognitive psychology, neural linguistics, risk communication and prose meet the hard sciences. In the Salish Sea, people are aching for meaning, narratives, tools and pathways to help protect what they love or what lines their wallets... but only if they understand the value of Puget Sound as a biological place, a community, an economy and a braided culture. The pathway from data to knowledge to understanding to action is a circuitous and long path which starts with clear communication and first and foremost, understanding our target audiences. These are the ...


Marine Protected Areas And The Role Of Engos In Supporting Mpa Establishment Within The Salish Sea, Ross Jameson, Jacob Chila Apr 2018

Marine Protected Areas And The Role Of Engos In Supporting Mpa Establishment Within The Salish Sea, Ross Jameson, Jacob Chila

Salish Sea Ecosystem Conference

The Salish Sea is a marine bioregion of extraordinary biological, cultural, spiritual, and socioeconomic value. These waters have sustained indigenous and non-indigenous coastal communities over generations by providing food, cultural, economic, and ecological services. With the growing impacts of human activities and climate change, conservation strategies are needed to ensure the future health of the Salish Sea. Marine protected areas (MPAs) are a tried-and-true conservation measure to protect an area’s natural and cultural resources. Public call for the establishment of an MPA within the Southern Strait of Georgia (SSoG), the waters surrounding the Canadian Gulf Islands near Victoria, started ...


Is Natural Recovery Occurring At Historic Log Storage Sites In Howe Sound?, Herb Herunter, Steve Macdonald Apr 2018

Is Natural Recovery Occurring At Historic Log Storage Sites In Howe Sound?, Herb Herunter, Steve Macdonald

Salish Sea Ecosystem Conference

Log handling and storage has contributed large amounts of wood waste to the benthic environments of Howe Sound over the last century. Rates of organic matter deposition in these areas far exceed those of natural origin. Debris, in the form of wood chips, bark, and whole logs, quickly overwhelm benthic environments leading to physical disruption and anoxic conditions unsuitable for most biota. It is estimated that these sites may remain relatively devoid of marine life for many years or decades. As such there is considerable interest in the actual size of these sites and remediation opportunities, especially in productive nearshore ...


Monitoring Stormwater Contaminants In The Puget Sound Nearshore: An Active Biomonitoring Tool Using Transplanted Mussels (Mytilus Trossulus), Jennifer Lanksbury, Andrea J. Carey, Mariko M. Langness, Brandi Lubliner, Laurie A. Niewolny, James E. West Apr 2018

Salish Sea Ecosystem Conference

Stormwater delivers a diverse range of contaminants to receiving waters including Puget Sound. Monitoring stormwater pollutants and their effects on biota is critical to informing best management practices aimed at recovering Puget Sound health. In the winter of 2012/13, the Washington Department of Fish and Wildlife’s Toxics-focused Biological Observation System (TBiOS) team conducted a pilot study using transplanted mussels to characterize the extent and magnitude of contamination in nearshore biota of Puget Sound. Mussels are now a key TBiOS indicator organism for tracking contaminants in the nearshore, and the Stormwater Action Monitoring (SAM) program has adopted mussels for ...


Ambient Monitoring To Inform The Protection Of Beneficial Uses And Achieve Water Quality Goals In Sinclair And Dyes Inlets, Puget Sound, Wa, Robert Johnston, Michelle Aylward, Gunther Rosen, Jonathan Strivens, Nicholas Schlafer, Marienne Colvin, Jill M. Brandenberger, Paul Caswell Apr 2018

Ambient Monitoring To Inform The Protection Of Beneficial Uses And Achieve Water Quality Goals In Sinclair And Dyes Inlets, Puget Sound, Wa, Robert Johnston, Michelle Aylward, Gunther Rosen, Jonathan Strivens, Nicholas Schlafer, Marienne Colvin, Jill M. Brandenberger, Paul Caswell

Salish Sea Ecosystem Conference

Currently discharge limits enforced under the Clean Water Act are focused on meeting National Pollution Discharge Elimination System (NPDES) limits at the end of the pipe and environmental performance is measured based on meeting the NPDES discharge limits; but meeting discharge limits has very little to do with achieving water quality goals for coastal and estuarine ecosystems. Therefore an effective monitoring and assessment program is needed to assess continuous process improvement, evaluate the ecological conditions, and provide metrics that can inform effective management of coastal and estuarine water quality. Here we report on an ambient monitoring program within Sinclair and ...

Understanding Shoreline Landowner Views On Water Quality Best Management Practices And Outreach, Robert C. Simmons, Darcy Mcnamara, Heidi Keller

Salish Sea Ecosystem Conference

Place-based research targeting rural shoreline property owners provided valuable insights into water quality issue awareness, viewpoints, and willingness to adopt best management practices (BMPs). This information can improve the efficacy of outreach programs designed to motivate shoreline homeowners to protect adjacent waterways. Between 2009 and 2016, 7 different sets of audience research were conducted to determine how to increase the voluntary adoption of water quality BMPs on private land. The studies focused on shoreline landowners and were conducted in rural areas in the South Puget Sound and Hood Canal regions of Washington State. Barriers and motivators for a variety of ...

Identifying Areas Of High Conservation Value In Howe Sound To Strengthen Regional Marine Spatial Planning, Fiona Beaty, Jessica Schultz, Bill Wareham

Salish Sea Ecosystem Conference

Marine spatial planning is a crucial step in the transition toward ecosystem-based management. It allows multiple users to co-manage marine spaces, minimizes user conflict, and informs marine conservation strategies. Spatial planning tools, such as web-based interactive maps, are especially useful in regions with complex and overlapping jurisdictions, where understanding processes outside of district boundaries can be both critical and difficult to achieve. Howe Sound/Atl’kitsem is one such region. The area is a fjord adjacent to Metro Vancouver and is within the traditional territory of the Squamish First Nation. Additionally, Howe Sound is governed by three regional districts, five ...


Interactive Effects Of Ocean Acidification And Ocean Warming On Pacific Herring (Clupea Pallasi) Early Life Stages, Brooke Love, Cristina Villalobos, M. Brady Olson Apr 2018

Interactive Effects Of Ocean Acidification And Ocean Warming On Pacific Herring (Clupea Pallasi) Early Life Stages, Brooke Love, Cristina Villalobos, M. Brady Olson

Salish Sea Ecosystem Conference

The synergy of ocean acidification and ocean warming may lead to negative marine organism responses not apparent under single stressors. While adult fish are effective acid-base regulators, and presumably less affected by environmental stressors, early life stages may be more susceptible. Pacific herring are ecologically and economically important forage fish, native to the U.S. Pacific Northwest (PNW). However, the herring populations in the PNW have experienced reductions in stock abundance. This study focused on the combined effects of ocean acidification and ocean warming on Pacific herring embryo and larval life stages. Pacific herring embryos were incubated under a factorial ...

Salish Sea Ecosystem Conference

There have been on-going efforts for increasing coastal resilience to the risk of coastal inundation as a result of sea-level rise in Washington. Accurate coastal risk projection depends on detailed and accurate information of sea level rise, including waves and storm surge induced by windstorms. This paper presents a modeling study simulating wind-induced waves in the Salish Sea. A nested-grid modeling approach was used to provide accurate and robust model simulations at various scales. The NOAA NCEP’s WaveWatch III (WW3) model is configured at global and regional scales with wind forcing obtained from the Climate Forecast System Reanalysis (CFSR ...


Turning The Ship: A New Direction For Managing Wood Waste In The Salish Sea Of Washington State, Russ Mcmillan, Chance Asher, John Evered, Celina Abercrombie Apr 2018

Turning The Ship: A New Direction For Managing Wood Waste In The Salish Sea Of Washington State, Russ Mcmillan, Chance Asher, John Evered, Celina Abercrombie

Salish Sea Ecosystem Conference

Wood waste has been a major driver in numerous large scale, nearshore cleanups in Washington State Its presence has contributed substantially to both the extent and volume of sediment requiring cleanup which is costly and time consuming. Success in dealing with wood waste must start with controlling sources and a reassessment of how timber-related uses of our waters are conducted. Recognizing its ecological impacts and the financial burden of cleanup prompts the change from practices that release wood waste to state waters. While it is tough to change from traditional use of waters for transport and storage of logs or ...


Age Truncation And Portfolio Effects In Puget Sound Pacific Herring, Margaret Siple, Andrew O. Shelton, Tessa B. Francis, Dayv Lowry, Adam P. Lindquist, Timothy E. Essington Apr 2018

Age Truncation And Portfolio Effects In Puget Sound Pacific Herring, Margaret Siple, Andrew O. Shelton, Tessa B. Francis, Dayv Lowry, Adam P. Lindquist, Timothy E. Essington

Salish Sea Ecosystem Conference

Forage fish undergo dramatic changes in abundance through time. Long-term fluctuations, which have historically been attributed to changes in recruitment, may also be due to changes in adult mortality. Pacific herring, a lightly exploited forage fish in Puget Sound, WA, have exhibited shifts in age structure and decreases in spawning biomass during the past 30 years. Here, we investigate changes in adult mortality as a potential explanation for these shifts. Using a hierarchical, age-structured population model, we indicate that adult natural mortality for Puget Sound Pacific herring has increased since 1973. We find that natural mortality has increased for every ...
