Vignette 20: Fraser River Estuary In Need Of Urgent Intensive Care, Laura Kehoe, Tara G. Martin May 2021

Vignette 20: Fraser River Estuary In Need Of Urgent Intensive Care, Laura Kehoe, Tara G. Martin

Institute Publications

The Fraser River is the lifeline of the Salish Sea, influencing its stratification, circulation, and primary productivity. If we do not take strong action to conserve the Fraser River estuary, two-thirds of the species at risk in this region are predicted to have a less than 50% chance of survival. Many of the region's most iconic species could disappear. Conservation action combined with environmental governance is a pathway for a brighter future for the Fraser River and other highly contested regions.


State Of The Salish Sea: Executive Summary, Kathryn L. Sobocinski May 2021

State Of The Salish Sea: Executive Summary, Kathryn L. Sobocinski

Institute Publications

This report synthesizes information on past, current, and emerging stressors within the Salish Sea estuarine ecosystem. The Salish Sea is a complex waterbody shared by Coast Salish Tribes and First Nations, Canada, and the United States. It is defined by multiple freshwater inputs and marine water from the Pacific Ocean that mix in two primary basins, Puget Sound and the Strait of Georgia. Human impacts are multifaceted and extensive within the Salish Sea, with a regional population of almost 9 million people. Population growth has driven urbanization and development, which in turn has triggered structural changes to the landscape and …

Vignette 08: Connection To Place: Indigenous Leadership In Səlilwət (Burrard Inlet), Tsleil-Waututh Nation’S Treaty Lands And Resources Department

Institute Publications

Since time out of mind, Tsleil-Waututh have used and occupied Burrard Inlet and surrounding watersheds. Generations of Tsleil-Waututh people were brought up with the teaching, “When the tide went out, the table was set.” About 90% of our diet was once derived from Burrard Inlet and the Fraser River, but today the Inlet is unable to support our needs. Cumulative effects of colonial settlement and development have eroded the ecological health, integrity, and diversity of the Inlet. Tsleil-Waututh Nation (TWN) has a goal to restore the health of the Inlet so that we, and future generations of Tsleil-Waututh People, can …


Section 1: Introduction, Kathryn L. Sobocinski May 2021

Section 1: Introduction, Kathryn L. Sobocinski

Institute Publications

Section 1 is an introduction to the report and the Salish Sea as a whole. The introduction provides an overview of the Salish Sea, the concept of "ecosystem health," and a roadmap to the rest of the report.


Section 2: Context, Kathryn L. Sobocinski May 2021

Section 2: Context, Kathryn L. Sobocinski

Institute Publications

Section 2 sets a foundation for understanding the Salish Sea ecosystem by describing its fundamental biophysical processes and structure, including estuarine circulation, ecological productivity, and an overview of several important biogenic habitats.


Section 3: Urbanization And Human Impacts To The Seascape, Kathryn L. Sobocinski May 2021

Section 3: Urbanization And Human Impacts To The Seascape, Kathryn L. Sobocinski

Institute Publications

Section 3 turns to an in-depth discussion of stressors and impacts to the ecosystem from population growth and urbanization, such as increases in impervious surfaces, hardening of shorelines, and the problems caused by a myriad of marine contaminants.


Section 4: Climate Change: A Global Problem With Local Impacts, Kathryn L. Sobocinski May 2021

Section 4: Climate Change: A Global Problem With Local Impacts, Kathryn L. Sobocinski

Institute Publications

Section 4 shifts from the local impacts of urbanization to the locally realized impacts of global climate change, including ocean acidification and sea level rise, followed by evidence of climate change in the ecosystem, ranging from phytoplankton and kelp, to wetlands, salmon, and marine birds.


Section 5: Cumulative Ecosystem Effects, Kathryn L. Sobocinski, Jennifer Boldt, Todd Sandell, Jaclyn Cleary, Michael Schmidt, Isobel Pearsall, Iris Kemp, Brian Riddell, Lynda V. Mapes May 2021

Section 5: Cumulative Ecosystem Effects, Kathryn L. Sobocinski, Jennifer Boldt, Todd Sandell, Jaclyn Cleary, Michael Schmidt, Isobel Pearsall, Iris Kemp, Brian Riddell, Lynda V. Mapes

Institute Publications

Section 5 introduces cumulative effects and brings in brief case discussions focused on herring, salmon, and orcas. Understanding the layers of stressors the ecosystem faces is integral to gaining a full picture of declines in ecosystem function.

Section 6 offers a list of science-based needs and opportunities brought to light by the report and various existing efforts within the Salish Sea science community, representing opportunities for greater collaboration across geographic and jurisdictional boundaries.


Vignette 06: Living Shorelines In Puget Sound, Jason Toft May 2021

Vignette 06: Living Shorelines In Puget Sound, Jason Toft

Institute Publications

Nearly one third of Puget Sound’s shorelines are armored (e.g., seawall, bulkhead, riprap). Armoring has documented negative impacts on the flora and fauna that benefit from healthy intertidal beaches. Although shoreline armor may be necessary in some cases to protect people and property, there are often promising “living shoreline” options to restore natural features, also referred to as soft or green shorelines. These options can be applied to situations where complete restoration is either impractical or not feasible given human constraints. Living shoreline techniques often include a mix of design options, including armor removal, sediment nourishment of beaches, log placement, …


Vignette 07: Stormwater Effluent Exerts A Key Pressure On The Salish Sea, Emily Howe May 2021

Vignette 07: Stormwater Effluent Exerts A Key Pressure On The Salish Sea, Emily Howe

Institute Publications

One of the primary terrestrial pressures on the Salish Sea estuarine and marine environment is urban stormwater runoff. When rainfall runs across hard, impervious surfaces, rather than soaking into the soil, it picks up and delivers toxic contaminants directly to nearby streams, rivers, and eventually the Salish Sea. In fact, for most toxic substances, surface runoff is the largest contributing source of loading to Puget Sound. Unfortunately, the Salish Sea’s relationship with stormwater effluent is no outlier; stormwater is the fastest growing cause of surface water impairment in the United States as urbanization transitions forested and other natural landscapes to …


Vignette 11: Ecological Consequences Of Built Shorelines In The Salish Sea, Stuart H. Munsch May 2021

Vignette 11: Ecological Consequences Of Built Shorelines In The Salish Sea, Stuart H. Munsch

Institute Publications

The world's population is disproportionately located near water. As a result, many nearshore ecosystems are highly modified. This is the case in the Salish Sea where many species rely on shoreline habitats. One of the major modifications to the Salish Sea's shoreline is armoring. Armored shorelines sever the connection between land and sea, preventing mutual exchange of nutrients and energy, influencing fish composition, and affecting photosynthetic species through overwater structures. By appreciating habitat impacts and how to mitigate them, we may steer toward a future that enables people and nearshore ecosystems to coexist. Restoring shorelines by removing armoring can recover …


Urban-Related Distribution Patterns Of An Iconic Salish Sea Mesopredator, The Giant Pacific Octopus (Enteroctopus Dofleini), Eliza C. Heery, Amy G. Olsen, Blake E. (Blake Edward) Feist, Kenneth P. Sebens Apr 2018

Urban-Related Distribution Patterns Of An Iconic Salish Sea Mesopredator, The Giant Pacific Octopus (Enteroctopus Dofleini), Eliza C. Heery, Amy G. Olsen, Blake E. (Blake Edward) Feist, Kenneth P. Sebens

Salish Sea Ecosystem Conference

Like many coastal areas globally, the Salish Sea has undergone rapid urbanization over recent decades. Terrestrial research suggests urbanization facilitates a variety of mesopredators by enhancing food and shelter resources and by limiting apex predation. Yet urbanization’s effect on mesopredators in the marine environment has rarely been examined. The giant Pacific octopus, Enteroctopus dofleini, is an iconic mesopredator of the Pacific Northwest due to its size and cognition, and is thought to reach a particularly large maximum size in inland waters of the Salish Sea. We examined the spatial distribution patterns and habitat use of giant Pacific octopus in Puget …
