To build communication, coordination, and information sharing among scientists and restoration practitioners, this project established a coastwide network from Baja California to British Columbia, the Native Olympia Oyster Collaborative. The project team synthesized past restoration projects, developed an experimental design for future research, and created educational and outreach materials that convey the importance of native oyster restoration on the Pacific coast. These efforts engaged communities in Olympia oyster restoration, provided tools to enhance future restoration outcomes, and strengthened connections among researchers and practitioners to support ongoing collaboration. This catalyst project was funded by NOAA through the National Estuarine Research Reserve System Science Collaborative to advance collaborative science. It did not produce any new data.

Blue carbon storage – carbon sequestration in coastal wetlands – can help coastal managers and policymakers achieve broader wetlands management, restoration, and conservation goals, in part by securing payment for carbon credits. Despite considerable interest in bringing wetland restoration projects to market, the transaction costs related to quantifying greenhouse gas fluxes and carbon storage in restored marsh has been a significant limiting factor to realizing these projects. The Waquoit Bay National Estuarine Research Reserve has been at the forefront of blue carbon research and end user engagement. Building on the efforts of a previous project, Bringing Wetlands to Market in Massachusetts, this project developed a verified and generalized model that can be used across New England and the mid-Atlantic East Coast to assess and predict greenhouse gas fluxes and potential wetland carbon across a wide environmental gradient using a small set of readily available data. Using this model, the project conducted a first-of-its-kind market feasibility assessment for the Herring River Restoration Project, one of the largest potential wetland restoration projects in New England. The project team developed targeted tools and education programs for coastal managers, decision makers, and teachers. These efforts have built an understanding of blue carbon and the capacity to integrate blue carbon considerations into restoration and management decisions.

The values of the Great Barrier Reef World Heritage Area (GBRWHA) are threatened by coastal development through habitat loss and runoff of sediment, nutrients and pollutants. Future coastal development is difficult to predict because it depends on volatile socio-economic and political factors. With this in mind, we developed a research project that uses spatially explicit scenario planning to identify plausible futures to 2035 for the GBRWHA coastal zone. The method used to produce maps of these scenarios is land-use change modelling using the GIS Idrisi. A governance analysis for the GBR coast is part of the project and is included in the scenario-planning process. Using a conservation planning approach, this project sets out to identify key priorities for restoring and protecting coastal ecosystems in the GBRWHA coastal zone. The objectives are to: - Compile spatial data on the coastal ecosystems and socio-economic characteristics of the GBRWHA coastal zone - Produce spatially explicit land use scenarios for the GBRWHA coastal zone to 2035 - Analyse the governance system in the GBRWHA coastal zone - Identify conservation goals for the GBRWHA coastal zone - Assess impacts of development for assets related to the conservation goals - Bring all the above information together to determine spatial options for allocating protection and restoration actions to achieve goals

Coastal researchers, fishermen, fishery managers and educators teamed up to understand changes in shrimp populations in response to shifting environmental conditions in estuaries. The Project Shrimping has deep cultural and economic ties to the South Carolina and Georgia coasts, and the southeast US Atlantic coast region as a whole. However, over the past two decades, commercial shrimp landings have been highly variable. Fishery management agencies, extension offices, and several southeastern Reserves have identified the need to better understand how shrimp populations are responding to changing environmental conditions, including warmer winters and altered salinity regimes. To do this work, a diverse team with members from universities, fishery management agencies, fisheries extension offices, and Reserves came together to form the Lowcountry Shrimp Collaborative. The Lowcountry Shrimp Collaborative used a comprehensive approach to examine how environmental conditions in estuaries are affecting abundance and timing of shrimp populations throughout the region through examination of each stage of the shrimp life cycle. Together, the Collaborative: Analyzed and synthesized numerous ongoing, long-term (30+ years) datasets on multiple shrimp life history stages (postlarval, juvenile, sub-adult, adult, commercially harvested) and environmental conditions (water quality, including System-Wide Monitoring Program data); Conducted field sampling targeting shrimp and their prey in salt marsh creeks during spring and summer seasons, over two years, at three southeast Reserves; Ran controlled seawater laboratory experiments to understand the impacts of competition for limited resources between shrimp species during their overlapping periods of estuarine residency; and, Interviewed commercial shrimpers based in Georgia and South Carolina, to better understand historical changes in, and perceptions of environmental impacts on, the shrimp industry in the southeast US. The project found that estuarine water temperature is rising across the region, mainly driven by increases during winter months. Warming temperatures can alter the life histories of shrimp, including shifting body size, altering the timing of migratory cues, and modifying habitat use. These warmer temperatures are also resulting in longer shrimping seasons with shrimpers often able to continue harvesting well into January. These results were confirmed by observations shared by shrimpers, who joined for a project wrap-up event where the team presented results and engaged in lively discussions about research needs and opportunities for collaboration between researchers, managers, and the industry.

This project synthesized Sentinel Site data for four New England National Estuarine Research Reserves (Great Bay, Narragansett, Waquoit Bay, and Wells), which have been individually monitoring salt marsh vegetation and elevation changes since at least 2011. The project team developed statistics-ready data packages linking vegetation change with surface elevation and other data, including output from an inundation tool. This project equipped New England reserves and coastal managers with new information to inform and improve the management, protection, and restoration of salt marshes. It produced an improved Sentinel Site monitoring protocol and established a methodology for analysis of marsh condition that can be used across the reserve system and by coastal managers nationwide. This catalyst project was funded by NOAA through the National Estuarine Research Reserve System Science Collaborative to advance collaborative science. It did not produce any new data.

Through the current project, the Chesapeake Bay-Virginia Reserve is building on the strengths of the previous years of CECB to extend the reach into Middlesex County, while developing an alumni program to support the program in Gloucester and Mathews. All three counties lie within a region experiencing relative rates of sea level rise greater than the global average. This science transfer project was funded by NOAA through the National Estuarine Research Reserve System Science Collaborative to promote the use of science. It did not produce any new data.

This project team will leverage a well established collaborative group, GTM Reserve’s Oyster and Water Quality Task Force and engage additional users, including state agencies, nonprofits and the oyster fishery community that are working to improve water quality in Guana River Estuary. To assist with the development of restoration and management plans, this project will: 1) identify sources of nutrients to the Guana River Estuary, and determine how nutrient loads from the lake to the river are affected by hydrology and land use; 2) map the current distribution of shellfish communities; 3) quantify filtration and nitrogen removal by shellfish; and 4) conduct field and lab experiments to assess how water quality affects shellfish health, and also how shellfish affect water quality in the estuary. In collaboration with project end users, the project team will generate a suite of research products, including a coupled hydrodynamic-biogeochemical model for Guana Lake and monitoring and restoration recommendations. Project findings will be shared through a stakeholder workshop exploring ways to reduce nutrient inputs into the estuary, a training program for using shellfish for water quality remediation, and peer-reviewed and outreach publications.

A team of collaborators from the Tijuana River National Estuarine Research Reserve, Southwest Wetlands Interpretive Association, and University of California-Davis are exploring the environmental consequences of managing the opening and closing of lagoon mouths. The project approach includes the following elements: Collaboration with Users: The project team will regularly engage members of the Southern California Wetlands Recovery Project, which coordinates and funds restoration projects throughout the region. Data Synthesis: Long-term water quality and vegetation data will be analyzed from three estuary systems: San Diego Bay, Los Peasquitos Lagoon, and Tijuana Estuary. The team will look at how mouth closures influence factors such as dissolved oxygen and salinity, which in turn affect plants and animals. Literature Review: The project team will pull together relevant scientific articles and reports to guide its interpretation of monitoring data and development of management recommendations.
