Coastal Wetland Area Change For Two Freshwater Diversions In The Mississippi River Delta, John R. White, Brady Couvillion, John W. Day
Coastal Wetland Area Change For Two Freshwater Diversions In The Mississippi River Delta, John R. White, Brady Couvillion, John W. Day
United States Geological Survey: Staff Publications
Coastal systems around the globe are being re-integrated with adjacent river systems to restore the natural hydrologic connection to riparian wetlands. The Mississippi River sediment diversions or river reconnections are one such tool to combat high rates of wetland loss in coastal Louisiana, USA by providing freshwater, sediment, and nutrients. There has been some disagreement in the published literature whether re-establishing river reconnection is slowing or contributing to coastal wetland loss. This issue is due to the difficulties in the application of remote sensing in low-relief environments where water level changes could indicate either land loss or simply temporary submergence. …
Connecting Communities To Coastal Resilience: Enhancing Sustainability Through Public Participation In Salt Marsh Management And Restoration In Suffolk County, Ny, Jennifer L. Mcgivern
Connecting Communities To Coastal Resilience: Enhancing Sustainability Through Public Participation In Salt Marsh Management And Restoration In Suffolk County, Ny, Jennifer L. Mcgivern
Dissertations, Theses, and Capstone Projects
Coastal resiliency is becoming significantly more critical to the livelihood of coastal communities as the frequency and intensity of storm events increases and is exacerbated by rising sea levels due to climate change. In October 2012 Superstorm Sandy impacted the New York-New Jersey area costing over $70 billion in storm damages and 147 lives lost, as storm surges surpassed record highs for the region. Protruding more than 100 miles into the Atlantic Ocean with over 1,000 miles of shoreline, Long Island is particularly vulnerable to the increasingly ferocious and numerous storms as well as the rising sea levels that climate …

As stony coral tissue loss disease (SCTLD) swept through the Florida Reef Tract, one of the most severely impacted species was the iconic pillar coral, Dendrogyra cylindrus. As the species’ population experienced a precipitous decline, a collaborative rescue project collected colony fragments for safekeeping at onshore and offshore nursery facilities. Between 2015 and 2019, a total of 574 fragments representing 128 genotypes were collected. These are currently dispersed among five facilities where they continue to provide opportunities to (1) refine best husbandry practices for D. cylindrus, (2) develop treatment options for SCTLD that have been adapted for use …
Factors Contributing To The Success Of Restored Oyster Reefs In The Choptank River Of The Chesapeake Bay, Virginia, Tara L. Bardar
Factors Contributing To The Success Of Restored Oyster Reefs In The Choptank River Of The Chesapeake Bay, Virginia, Tara L. Bardar
HCNSO Student Capstones
Populations of Crassostrea virginica, the Eastern oyster, have been declining since the late 1800s. While overharvesting is the primary cause of decline, the Eastern oyster is also facing the threat of disease and habitat loss. As oyster populations decline, habitat suitable for oyster spats declines as well, as these prefer to settle on the shells of other oysters that have formed reefs. Knowing this, oyster restoration projects have been focused around testing methods that will increase recruitment of spat and allow oyster reefs to form. A current and ongoing restoration project in the Choptank River of the Chesapeake Bay, …

The rapid shrinkage of Lake Urmia, one of the world's largest saline lakes located in northwestern Iran, is a tragic wake-up call to revisit the principles of water resources management based on the socio-economic and environmental dimensions of sustainable development. The overarching goal of this paper is to set a framework for deriving dynamic, climate-informed environmental inflows for drying lakes considering both meteorological/climatic and anthropogenic conditions. We report on the compounding effects of meteorological drought and unsustainable water resource management that contributed to Lake Urmia's contemporary environmental catastrophe. Using rich datasets of hydrologic attributes, water demands and withdrawals, as well …
Identifying Disease-Resistant And Thermal-Tolerant Genotypes In The Threatened Staghorn Coral, Acropora Cervicornis, Morgan V. Hightshoe
Identifying Disease-Resistant And Thermal-Tolerant Genotypes In The Threatened Staghorn Coral, Acropora Cervicornis, Morgan V. Hightshoe
HCNSO Student Theses and Dissertations
Since the 1970s, loss of herbivores, coral bleaching, pollution, and disease epidemics have reshaped the ecological framework of coral reefs. Staghorn coral, Acropora cervicornis, was a major reef-building scleractinian coral found throughout Florida and the Caribbean that experienced unprecedented population declines primarily due to disease and coral bleaching. These two stressors are coupled; the highest coral disease prevalence occurs after periods of thermal stress caused by increased sea surface temperature. Previous research documented three disease-resistant A. cervicornis genotypes in Panama, but it is unknown if disease-resistant genotypes exist in the Florida Keys. Thermal tolerance has been found to be …
Working On The Railroad: Coastal Streams Prioritization To Inform Restoration Planning, Paul Schlenger, Phil Bloch, Jennifer Griffiths
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, the …

Survival Of Hatchery-Origin Juvenile Pinto Abalone (Haliotis Kamtschatkana) Outplanted To Restoration Sites In The San Juan Islands, Henry Carson, Michael Ulrich, Josh Bouma
Salish Sea Ecosystem Conference
The Washington Department of Fish and Wildlife, Puget Sound Restoration Fund, and other project partners have outplanted thousands of hatchery-reared pinto abalone in annual cohorts to ten sites in the San Juan Archipelago since 2009. We measured the “success” of each outplant site by the proportion of total juveniles placed that survived to a reproductive size. In winter 2017 surveys we observed a range of successes, from 0% at the worst site to 5.6% at the best. When nearby individuals are included, this success ranges as high as 7.5%. These percentages do not account for the probability of detection for …
Salish Sea Bull Kelp Restoration Research: Local, Regional And International Collaborations, William Heath, Sherryl Bisgrove
Salish Sea Bull Kelp Restoration Research: Local, Regional And International Collaborations, William Heath, Sherryl Bisgrove
Salish Sea Ecosystem Conference
Bull kelp forests are important nearshore habitats for many fish and invertebrates and are an integral part of the “salmon highway” from river to estuary to ocean and back. In recent decades kelp forests have been in serious decline in the Salish Sea and other coastal regions. Research to improve our understanding of causes of the decline and on restoration methods began in the north Salish Sea in 2011 with a kelp out-planting project by Nile Creek Enhancement Society(NCES) at Hornby Island. NCES and Project Watershed began a collaboration in 2015 with work in the K'omoks Estuary and Cape Lazo …
What's Working To Restore Puget Sound? Connecting Investments, Actions, And Outcomes, Leska S. Fore, Keith Dublanica, Jennifer Johnson, Jessica Archer
What's Working To Restore Puget Sound? Connecting Investments, Actions, And Outcomes, Leska S. Fore, Keith Dublanica, Jennifer Johnson, Jessica Archer
Salish Sea Ecosystem Conference
Throughout Puget Sound, long-term funding and investment in recovery actions have resulted in measurable improvements. Results from individual projects have been reported anecdotally in terms of improved water quality, habitat condition and wildlife, and salmon populations. Yet our ability to report these positive outcomes to funding agencies has been limited. This is because information and results are scattered across databases maintained by multiple local, state, tribal, and federal agencies. Data sets are typically well curated, but not connected. We have developed a prototype of a web tool that combines information about actions and outcomes to demonstrate the value of investments …

Hall, Todd Zackey, Frank Leonetti, Michael Rustay
Salish Sea Ecosystem Conference
Landscape context is critical in estuary restoration planning and assessment due to the complexity and size of estuaries, and the unique attributes and cumulative effects of individual restoration projects. In addition, the diversity and mobility of estuarine species, in particular juvenile salmon, highlights the importance of landscape position given certain locations in the delta are less accessible to salmon. The Snohomish River delta has been the focus of major estuary restoration efforts in recent years and efforts could result in the largest cumulative estuary restoration action in Puget Sound. While several large projects have been initiated/competed in recent years, information …

Restoration Action Effectiveness: Employing The Concept Of Net Ecosystem Improvement, Ronald M. Thom, Thomas Mumford, Lucas Hart, Richard Childers
Salish Sea Ecosystem Conference
The mission statement of the Northwest Straits Initiative includes ‘improving ecosystem health’ of the Strait of Juan de Fuca and Northern Puget Sound by restoring and protecting natural habitats and resources. For the Initiative, and many other programs, defining ‘ecosystem health’ and developing relevant and measureable health metrics is problematic, and yet critical to both assessing program action effectiveness as well as justifying investments. The Initiative is exploring utilizing the concept of net ecosystem improvement (NEI) to summarize results of actions and couch the results in a broader ecosystem perspective. Net improvement is defined as following development; there is an …
The Fisher Slough Case Study: Seven-Year Monitoring Summary: Measuring Outcomes For Fish, Farms And Flooding, Jenny Lynn Baker
The Fisher Slough Case Study: Seven-Year Monitoring Summary: Measuring Outcomes For Fish, Farms And Flooding, Jenny Lynn Baker
Salish Sea Ecosystem Conference
Half of Puget Sound’s wild Chinook salmon come from the Skagit River. Although the number dropped dramatically as 80 percent of salmon habitat in the river delta was lost over the last two centuries, the Skagit remains a critical stronghold for Puget Sound Chinook. The Skagit Chinook Recovery Plan calls for 2,700 acres of estuary restoration. But with farms in Skagit County generating more than $500 million each year, there are concerns that habitat restoration would mean loss of agricultural land, and the economy and culture it supports. The Fisher Slough project was intended to overcome long-standing conflicts between farm …

Levin, Michael W. Schmidt, Raphael Girardin
Salish Sea Ecosystem Conference
Local, state, federal, tribal and private stakeholders have committed significant resources to restoring Puget Sound’s terrestrial-marine ecosystem. Though jurisdictional issues have promoted a fragmented approach to restoration planning, there is growing recognition that a more coordinated systems-based restoration approach is needed to achieve recovery goals. This presentation describes our collaborative effort to develop and apply an integrated environmental and human systems modeling framework for the Puget Sound Basin, inclusive of all marine and land areas (1,020 and 12,680 sq. mi.). Our goal is to establish a whole-basin systems modeling framework that dynamically simulates biophysical interactions and transfers (water, nutrients, contaminants, …

Shoreline Armoring Removal: Assessment Of Restoration Effectiveness In The Salish Sea, Jason David Toft, Jeffery R. Cordell, Megan Nichols Dethier, Emily Howe, Hannah Faulkner
Salish Sea Ecosystem Conference
Shoreline armoring removal is becoming a common restoration technique in the nearshore of the Salish Sea, yet we lack a comprehensive understanding of the ecological benefits obtained, and how such an understanding could be used to inform management recommendations and educate diverse audiences. To address this knowledge gap, we studied effects of shoreline armor removal at 10 sites, expanding the spatial framework of what was previously known by collaborating across academic (University of Washington), agency (Washington Department of Fish and Wildlife), and citizen science groups. Each site had three beach types of: (1) restored beaches with armoring removed 1-11 years …

Chinook Habitat Restoration Decision Support Tool- Identifying Chinook Salmon Habitat Restoration Effectiveness Based On Temperature, Flow, And Bioenergetics Models, Andrew Spanjer, Patrick W. Moran, Robert Black
Salish Sea Ecosystem Conference
Stream restoration projects focus on improving habitat for Pacific Salmonids in watersheds throughout the Pacific Northwest. Currently, few comprehensive tools are available for managers to mechanistically predict the improved fish growth that comes with restoration actions, such as riparian acquisitions, riparian planting or levee setbacks. Therefore, managers need tools that can predict salmonid growth potential given different decision scenarios. One approach to address the Puget Sound Partnership’s regional chinook recovery goals would be a linked stream temperature, flow, and fish bioenergetics model that predict chinook growth benefits of different remediation strategies. Considered strategies will include changes to riparian habitat and …
The Transformation Of Port Gamble Bay: From Remediation To Restoration, Celina Abercrombie
The Transformation Of Port Gamble Bay: From Remediation To Restoration, Celina Abercrombie
Salish Sea Ecosystem Conference
For over 140 years, a lumber mill operated at the mouth of Port Gamble Bay producing lumber and other wood products, and leaving behind a legacy of contamination and degraded habitat when it closed its doors in 1995. Fast forward to the present when state and federal agencies, local government, tribes, community groups, and industry teamed up to cleanup, restore and preserve the bay’s high-quality natural resources. Undertaking extensive cleanup and the largest creosote-treated piling removal effort in the Puget Sound, Pope Resources removed contaminated sediment, over 8,500 creosote-treated pilings and numerous overwater structures to improve over 3,000 feet of …
Is Local Adaptation A Factor In Planning Eelgrass Restoration? Initial Assessment Of Responses To Temperature By Eelgrass Growing Across A Stressor Gradient, Kate Buenau, Celia Thurman, John Vavrinec, A. B. (Amy B.) Borde, Ronald M. Thom
Is Local Adaptation A Factor In Planning Eelgrass Restoration? Initial Assessment Of Responses To Temperature By Eelgrass Growing Across A Stressor Gradient, Kate Buenau, Celia Thurman, John Vavrinec, A. B. (Amy B.) Borde, Ronald M. Thom
Salish Sea Ecosystem Conference
Large-scale eelgrass restoration in an environment as complex as the Salish Sea requires estimating the effects of a wide range of environmental conditions (e.g. temperature, salinity, turbidity) on the effectiveness of restoration actions in different locations. We have developed a spatial model of eelgrass growth in response to environmental drivers, based on physiological data collected in Sequim Bay, WA, to aid in identifying restoration sites. However, field tests suggest that the model underestimates the capability of eelgrass to grow in conditions more stressful than Sequim Bay. A critical uncertainty is the extent of localized genotypic and/or phenotypic adaptations by eelgrass …
Plant Community And Nutrient Development Within Four Estuary Restoration Sites In Kitsap County, Washington, Shannon Call, Jenise M. Bauman
Plant Community And Nutrient Development Within Four Estuary Restoration Sites In Kitsap County, Washington, Shannon Call, Jenise M. Bauman
Salish Sea Ecosystem Conference
Estuaries affected by physical barriers, such as culverts, experience reduced hydrological inputs and reduced connectivity resulting in the loss of ecological processes. To address reduction in ecological connectedness, culverts at three sites were removed and replaced with bridges. An observational field study was conducted in Kitsap County, Washington of three sites where culverts were replaced with bridges three, eight, and 13 years ago. Data was collected at a reference site where the estuary contains a culvert. It is hypothesized that estuary restoration will recover plant species, carbon sequestration, and nutrient cycling homogeneity above and below the restoration site. However, the …

Salish Sea Ecosystem Conference
Eelgrass (Zostera marina) is one of 25 Vital Signs to track the health of Puget Sound and restoration of this critical nearshore habitat is part of the overall regional recovery strategy. Eelgrass restoration will provide a multitude of benefits, ranging from habitat for species to ameliorating the effects of climate change. Since 2013, the Washington State Department of Natural Resources has led regional evaluation of potential eelgrass restoration sites and transplanting in Washington State. Through collaborations we have developed and tested strategies to enhance transplant success and restore natural processes. We developed an eelgrass transplant suitability model to identify potential …
Sea Level Rise Guidance For Nearshore Habitat Restoration In Puget Sound, Harriet Morgan, Nicole Faghin, Jay Krienitz, Tish Conway-Cranos
Sea Level Rise Guidance For Nearshore Habitat Restoration In Puget Sound, Harriet Morgan, Nicole Faghin, Jay Krienitz, Tish Conway-Cranos
Salish Sea Ecosystem Conference
Many agencies, organizations, and communities across Puget Sound are working to restore nearshore habitats from historic degradation to reestablish or maintain the functionality of these ecosystems. Sea level rise is expected to cause increased coastal flooding in low-lying areas and increased storm surge reach in coastal zones. There is widespread recognition that these new threats must be addressed in the siting, design, and maintenance of Puget Sound’s nearshore habitat restoration projects, especially given the limited resources available for restoration. In spite of this, existing information on sea level rise has not yet been synthesized in a way that facilitates incorporation …
Lessons Learned: Tidal Marsh Restoration In A Dynamic Context Of Stress And Climate Change, Roger Nathan Fuller
Lessons Learned: Tidal Marsh Restoration In A Dynamic Context Of Stress And Climate Change, Roger Nathan Fuller
Salish Sea Ecosystem Conference
In the Stillaguamish estuary, tidal wetlands have been receding for decades as a result of both natural and anthropogenic changes. Despite current restoration efforts, monitoring suggests that rising stress from climate change impacts on summer flows, legacy stresses from the levee system, and increased plant mortality from avian and insect herbivores may interact to accelerate the rate of marsh loss. Lessons learned from a 2012 restoration project should inform adaptive management and future restoration projects. Post-restoration monitoring has revealed a pattern of interacting stresses at both the site and system scales that affects marsh productivity and resilience to climate change. …

The project was part of the port authority’s Habitat Enhancement Program, which focuses on creating, restoring and enhancing fish and wildlife habitat. The project presented a significant opportunity to restore coastal wetland habitat on the south shore of Burrard Inlet. The creation …
Fir Island Farm: Estuary Restoration Project: Designing For Climate Change And Uncertainty In Shoreline Flood Risk Reduction And Ecosystem Restoration Projects, David Cline
Salish Sea Ecosystem Conference
The recently designed and constructed Fir Island Farm – Estuary Restoration Project involves construction of a 1-mile long shoreline levee (dike) setback for restoration of 130 acres of farm land for tidal marsh estuary ecosystem restoration. The key uncertainty, and resiliency, design elements of concern include 1) selection of dike level of protection and design elevations considering climate change sea level rise projections, 2) inclusion of erosion protection measures, 3) farm drainage tailwater conditions and 4) ecosystem marsh vegetated plain future elevations and large woody debris loading conditions. This presentation discusses how site characterization, instrumentation, numerical modeling and monitoring were …
Collaborative Solutions To Riparian Protection And Restoration In The Chimacum Creek Watershed, Sarah Doyle
Collaborative Solutions To Riparian Protection And Restoration In The Chimacum Creek Watershed, Sarah Doyle
Salish Sea Ecosystem Conference
For several decades, the North Olympic Salmon Coalition (NOSC) has been working with agricultural producers in the Chimacum Creek Watershed to plant riparian buffers and restore salmon habitat. In recent years, NOSC and partners have had difficulty engaging landowners to participate in riparian restoration and protection programs due to issues regarding drainage, reed canary grass and beaver damage. To help guide us in how to address these barriers to landowner willingness, NOSC partnered with local entities to develop a Chimacum Creek Protection and Restoration Strategy. Since the strategy has been implemented, four priority farms are now being considered for protection …
Integrating Watershed-Scale And River-Reach Protection And Restoration Planning To Promote Climate Resilience In The South Fork Nooksack River (Sfnr), Oliver Grah, Susan Dickerson-Lange
Integrating Watershed-Scale And River-Reach Protection And Restoration Planning To Promote Climate Resilience In The South Fork Nooksack River (Sfnr), Oliver Grah, Susan Dickerson-Lange
Salish Sea Ecosystem Conference
The Nooksack Indian Tribe reservation is located at the foot of the North Cascades Mountains, approximately 13 miles east of Bellingham, WA and the Salish Sea. The Tribe relies on a harvestable surplus of Pacific salmon in the Nooksack River for cultural, subsistence, and commercial purposes. Today, Pacific salmon runs are less than 10 percent of the runs in the late 1800’s. Causes of the declines are complex; however, it is well understood that the legacy of commercial forestry, agriculture, and development has increased sediment loading and water temperature. Climate impacts will cumulatively add to the legacy impacts, which are …

The increasing availability of commercial off-the-shelf unmanned systems is placing powerful data acquisition tools within reach of scientists and engineers engaged in coastal management, restoration, and remediation. Two diverse use cases are presented here which showcase the effectiveness of combined mapping by Unmanned Aircraft System (UAS) and Unmanned Surface Vessel (USV) to generate orthomosaic imagery and 3D digital surface models of subaqueous/subaerial terrain in low-lying and intertidal settings. These examples include combined UAS structure from motion (SfM) photogrammetry and USV single-beam sonar bathymetry: (1) to inform remedial design alternatives at an intertidal mudflat cleanup site in Class B airspace; and …
Structure From Motion On Salish Shores: Remote Mapping For Restoration, Branden Rishel
Structure From Motion On Salish Shores: Remote Mapping For Restoration, Branden Rishel
Salish Sea Ecosystem Conference
This talk will showcase several projects by Coastal Geologic Services (CGS) in which structure from motion (SfM) modeling played a critical role, while also briefly discussing the advantages and possible applications of this relatively new technology. Over the last few years, SfM has transformed from an emerging technology to a reliable, efficient, and cost-effective method for constructing aerial orthophoto mosaics and 3D models of coastal landscapes. Low-altitude aerial imagery, such as from inexpensive drones (UAS or UAV), can be used to create point clouds that exceed LiDAR resolution and accuracy, at a much lower cost. This enables 3D scanning of …
Protection And Restoration Of Salmon Bearing Streams In Agricultural Landscapes Of The Puget Sound Basin: A Synthesis Of Approaches To Reach-Scale Planning For Eight Focus Areas, Colin Hume
Salish Sea Ecosystem Conference
In 2015 the Department of Ecology led development of a new initiative to protect and restore riparian areas on salmon bearing streams across agricultural landscapes of the Puget Sound Basin. Using Environmental Protection Agency National Estuary Program funding through the Watershed Lead Organization, the initiative solicited grant proposals from local organizations to develop reach-scale plans for river reaches that provide the strategic basis for a subsequent phase of implementation funding to acquire riparian zones from willing landowners either through conservation easement or fee-simple purchase. Grants were awarded to an array of partnerships between land trusts, Native American tribes, local governments, …
