This project will provide research staff members from the mid-Atlantic reserves with targeted tools, graphical support, and training to facilitate the use of reserve monitoring data. The project team will focus on deciphering trends in water quality parameters, which are related to management issues such as storm surge mitigation. Through workshops and the development of statistical applications, this project will increase capacity to distill monitoring data into a format that resource managers can use. The project team will share their approach and project outputs with the larger reserve system, and collectively, these efforts will demonstrate the value of the reserve monitoring program. 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.

The National Estuarine Research Reserve System has developed a consistent protocol for monitoring vegetation across the nations estuaries. Eventually, the goal is to be monitoring vegetation regularly at every Reserve, allowing for robust spatial and temporal analyses of estuarine vegetation trends. To date, 18 Reserves have implemented this vegetation monitoring protocol. The vegetation community that is assessed varies by reserve. The protocol has been implemented for submerged aquatic vegetation such as eelgrass and algae, as well as for emergent vegetation such as salt marshes and mangroves. The vegetation monitoring protocol involves permanent sampling plots along fixed transects. Parameters monitored include percent cover of all plant species, as well as stem density and canopy height of the common species. Elevation is also assessed for each plot when feasible. The complete monitoring protocol provides more details. These data will be valuable for tracking changes in abundance of particular species of interest, or in species composition over time. For instance, the transects can be used to detect landward migration of vegetation communities in the face of projected sea level rise. The National Estuarine Research Reserves is a network of 30 reserves protected for long-term research, ecosystem monitoring, education, and coastal stewardship. Established by the Coastal Zone Management Act, the reserve system is a partnership program between NOAA and the coastal states. NOAA provides funding, national guidance, and technical assistance. Each reserve is managed on daily basis by a lead state agency or university with input from local partners. These data are collected as part of the NERRS System-Wide Monitoring Program (SWMP), which includes (1) abiotic indicators of water quality and weather; (2) biological monitoring; and (3) watershed, habitat, and land use mapping. Data were collected under individual Reserve NOAA grant/cooperative agreements and managed by the CDMO under NOAA grant/cooperative agreement #NA23NOS4200321 (2023) and prior grants.

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.

This project is providing a direct assessment of the ecological effects of multiple-use zoning on inshore reefs of the GBRMP. Underwater visual census (UVC) monitoring of fish and benthic communities is being carried out at 50 no-take marine reserve (green zone) sites and at 50 sites that have remained open to fishing within the Palm, Magnetic, Whitsunday and Keppel Island groups. Long-term monitoring surveys are providing information on:,

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.

Southern California’s coastal environments are under intense development pressure. In the Tijuana River Valley, this pressure translates into the fragmentation and loss of coastal wetlands that provide invaluable services, such as water quality protection. Conserving and restoring these wetlands has become a priority for regional coastal managers, scientists, and environmental organizations. However, despite a wealth of knowledge about these coastal systems, decision-makers lack essential information to transform wetland recovery and management priorities into action.

This project tested the use of eDNA methods to identify fish communities, assess biodiversity, and detect invasive crabs in different types of estuaries and connected streams. Samples were collected at Apalachicola, Great Bay, He’eai, Hudson, South Slough and Wells Reserves in 2018 and 2019. The project deployed two methods to analyze DNA in water samples: metabarcoding that identifies a wide range of species, and digital droplet Polymerase Chain Reaction (ddPCR) that identifies a single target organism. The team conducted baseline community assessments for fish at five reserve sites and conducted a survey of anadromous fish in a tributary stream at the sixth reserve. The project found that fish community and biodiversity assessments are well suited to eDNA applications, while invasive crabs are much harder to detect because they do not shed much DNA. The project developed protocols and recommendations for the collection, filtering, and extraction of eDNA samples at estuarine sites, and provided information which will support the design of sampling programs for fish communities.

People receive numerous benefits from nature, such as water purification, coastal protection, and food production. These ecosystem services are an increasingly important consideration for coastal managers as they design management interventions to protect coastal habitat. This includes National Estuarine Research Reserve managers, who are working to better understand ecosystem services across the reserve system. However, without a standardized approach it has been difficult for coastal managers to consistently incorporate ecosystem services into programs or projects. In response to this need, researchers with Duke University’s National Ecosystem Services Partnership developed Ecosystem Services Conceptual Models (ESCMs) for estuarine habitats that diagram the way a management intervention cascades through an ecological system and provides benefits to people. The Duke team built on previous work that created an ecosystem services modeling approach for salt marsh. In partnership with the Rookery Bay and North Carolina National Estuarine Research Reserves and their stakeholders, the team led a series of workshops to produce site-specific and generalized Ecosystem Services Conceptual Models for mangrove and oyster habitat restoration in the southeast United States. 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.

Critical habitat is habitat needed to support recovery of listed species. When a species is listed under the Endangered Species Act, NOAA Fisheries is required to determine whether there are areas that meet the definition of critical habitat. Once critical habitat is designated, other federal agencies consult with NOAA Fisheries to ensure actions they fund, authorize, or undertake are not likely to destroy or adversely modify the critical habitat. Critical habitat is defined as: Specific areas within the geographical area occupied by the species at the time of listing that contain physical or biological features essential to conservation of the species and that may require special management considerations or protection; and Specific areas outside the geographical area occupied by the species if the agency determines that the area itself is essential for conservation.
