Oysters are the tiny superheroes of coastal environments. They enhance water quality, create habitat, and protect shorelines from storms and erosion. Along the Pacific Coast, native oysters are in decline, due in part to sedimentation, inadequate protection, and unsustainable harvests. Planning for a future that includes healthy native oyster populations depends on our ability to select sites for restoration that not only account for these challenges but also the impacts of a changing climate.

The Eastern oyster (Crassostrea virginica) is a keystone species in northeast Florida estuaries, including the Guana Tolomato Matanzas (GTM) Reserve. However, scientists, managers and oyster harvesters are concerned about the long-term persistence and viability of local populations. In the GTM Reserve, water quality issues are causing some areas to be closed for harvesting, which could be intensifying harvesting pressure in remaining open areas. Other factors, such as predation, disease, and increased salinity, can also slow growth or kill oysters. This complicated situation recently led stakeholders and reserve staff to establish the GTM Oyster Water Quality Task Force in order to identify causes and collaboratively address the region’s oyster challenges.

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.

Pint-sized with razor-sharp edges, Olympia oysters once flourished along Oregon’s rugged coast. Millions of them formed extensive beds that blanketed the tidal zones of places like Coos Bay and Yaquina bays, where they provided food and income for people and habitat for wildlife. In recent years, over-harvesting, development, sedimentation, pollution, dredging, and forest fires have all played a role in the dramatic decline of this native shellfish that, in many places, has become locally extinct. Bringing the “Oly” back is a priority for natural resource managers, scientists, shellfish farmers, and recreationists.

The project team produces educational outreach materials for audiences throughout Grand Bay. The materials will raise awareness of the positive and negative effects of land-use change for the general public, community organizations, and decisionmakers within the region. The materials will educate audiences about the ways to preserve and protect Grand Bay from waterborne pathogens and excess nutrients. The team will use science-based information to reinforce the importance of reducing stormwater contamination, improving wastewater management, and implementing land-use planning that takes water resources into account. 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.

We used a quantitative sampling device to compare nekton use among high-relief live oyster reef, vegetated marsh edge Spartina alterniflora, and nonvegetated bottom habitat types.

In this project, the Jacques Cousteau National Estuarine Research Reserve and Rutgers University, who have collaborated for more than a decade to develop coastal resilience tools, streamlined and enhanced existing mapping and decision-support tools for New Jersey coastal communities. The result was New Jersey Flood Mapper, an interactive, user-centered web tool that enables decision-makers to visualize exposure from coastal flooding hazards. The tool operationalizes a total water level concept developed by Rutgers climate resilience experts to allow planners to evaluate a range of flood conditions and time horizons. Enhanced map overlaps and data layers that show physical infrastructure, evacuation routes, and socio-demographic information are integrated into the tool to give a fuller picture of community vulnerability. New Jersey Flood Mapper offers coastal decision makers a go-to resource to assess and plan for potential risks to people and property from future storms and flooding.

In South Carolina, the Eastern oyster is an ecosystem “all-star.” It filters huge volumes of water, creates habitat for commercial and recreational fisheries, and is a local delicacy. Thriving oyster reefs serve as natural breakwaters protecting South Carolina’s fringing marshes from wave action and erosion. The loss of oyster reefs—whether caused by development, pollution, overharvest, disease, or sea level rise—accelerates coastal erosion and causes ecosystem health to decline. These impacts are especially apparent along the state’s heavily trafficked Intracoastal Waterway and its barrier islands, which historically have protected the mainland from the Atlantic’s waves and storms.

The National Estuarine Research Reserve System has a proven track record of successfully transferring and translating reserve science to a broad suite of educators through teacher workshops. In recent years, teachers expressed a need for curriculum, data sets, and professional development related to climate change.

This project will enhance stakeholder capacity to make informed decisions on the protection and restoration of buffers around the Great Bay Estuary by addressing the following question: What are the options for addressing the challenges to effectively protect and restore buffer zones around New Hampshire's Great Bay? The project will support strategic agency and nonprofit investments; inform strategies for outreach professionals to work with towns on water quality improvement, habitat protection, climate adaptation, and nonpoint source pollution control; and lead to new research questions. This integrated assessment project was funded by NOAA through the National Estuarine Research Reserve System Science Collaborative to evaluate options for action. It did not produce any new data.
