Coastwide Reference Monitoring System

The Coastwide Reference Monitoring System is a coordinated network for measuring wetland condition and restoration outcomes along the Louisiana coast of the United States. It integrates broadly recognized protocols from agencies such as the United States Geological Survey, National Oceanic and Atmospheric Administration, and United States Fish and Wildlife Service to support policy decisions by entities including the Mississippi River Commission and the Louisiana Coastal Protection and Restoration Authority. The program informs project design by linking biological metrics to landscape change across the Gulf Coast and the Mississippi River Delta.

Overview

The program establishes standardized reference sites and sampling methods to detect ecological responses to interventions by organizations such as the U.S. Army Corps of Engineers, the National Park Service, and the Natural Resources Conservation Service. It coordinates with regional efforts like the Coastal Wetlands Planning, Protection and Restoration Act implementation and complements monitoring from the Environmental Protection Agency, the National Aeronautics and Space Administration, and academic partners at institutions such as Louisiana State University, Tulane University, and the University of New Orleans. The network supports restoration evaluation for projects funded by programs including the Gulf Coast Ecosystem Restoration Council and the Coastal Wetlands Planning, Protection and Restoration Act-related initiatives.

History and Development

The system evolved from post-disaster and restoration monitoring needs after events like Hurricane Katrina and in response to the scale of land loss in the Mississippi River Deltaic Plain. Early collaborators included the Louisiana Department of Natural Resources, the Louisiana State University Agricultural Center, and federal partners such as the USGS National Wetlands Research Center. Development drew on precedents set by monitoring frameworks like the National Estuarine Research Reserve system and large-scale programs such as the Cooperative Institute for Research to Operations in Hydrology. Funding and governance were influenced by legislation and settlement-driven programs tied to the Deepwater Horizon oil spill and subsequent restoration funding routed through the Natural Resource Damage Assessment process and the Gulf Restoration efforts.

Objectives and Methodology

Primary objectives include establishing reference-condition baselines, quantifying trajectories of vegetative and geomorphic change, and providing defensible data for adaptive management used by the Louisiana Coastal Protection and Restoration Authority and the National Fish and Wildlife Foundation. Methodology integrates floristic assessments, soil and elevation measurements, hydrologic sampling, and remote sensing derived from platforms like Landsat, MODIS, and airborne lidar collected in coordination with the USGS Earth Resources Observation and Science (EROS) Center. Protocols align with standards from the American Society for Testing and Materials when applicable and incorporate statistical designs used by the United States Geological Survey and modeling tools such as Delft3D, SLAMM (Sea Level Affecting Marshes Model), and hydrodynamic models developed for the Mississippi River Gulf Outlet studies.

Data Collection and Monitoring Programs

Data collection occurs across permanent transects, quadrats, and instrumented sites with metrics collected for vegetation composition, aboveground biomass, peat accretion, sediment deposition, and surface elevation change (e.g., using Surface Elevation Tables and feldspar marker horizons). Monitoring programs coordinate with long-term datasets maintained by the National Oceanic and Atmospheric Administration tide and current stations, the National Water Information System from the United States Geological Survey, and satellite archives from NASA missions. The system feeds into regional data hubs used by the Gulf of Mexico Alliance, the Louisiana Coastal Information Center, and research networks at Southeastern Universities Research Association members.

Governance and Partnerships

Governance is multi-agency and partnership-based, involving state and federal entities such as the Louisiana Coastal Protection and Restoration Authority, the United States Fish and Wildlife Service, the National Oceanic and Atmospheric Administration, and academic partners including Louisiana State University and University of Louisiana at Lafayette. Nonprofit and stakeholder partners include the National Audubon Society, The Nature Conservancy, and regional organizations that coordinate with federal programs like the North American Wetlands Conservation Act funded projects. Cooperative agreements and memoranda of understanding with agencies such as the U.S. Army Corps of Engineers and the Bureau of Ocean Energy Management support shared access to technical resources and data.

Applications and Impact

Results guide engineering and ecological design for large-scale projects such as river diversions authorized by the Coastal Wetlands Planning, Protection and Restoration Act and efforts tied to State Master Plan for Coastal Protection and Restoration of Louisiana. Data inform environmental assessments under the National Environmental Policy Act and compensation planning associated with the Deepwater Horizon oil spill settlements and Natural Resource Damage Assessment processes. The system’s outputs have been cited in peer-reviewed literature from journals such as Estuarine, Coastal and Shelf Science, Journal of Coastal Research, and Restoration Ecology, and inform outreach by institutions like the Louisiana Sea Grant program.

Challenges and Future Directions

Challenges include scaling monitoring across heterogeneous habitats, integrating new remote-sensing technologies from programs like ICESat-2 and high-resolution unmanned aerial systems used by Federal Aviation Administration-regulated teams, and maintaining sustained funding from federal appropriations and restoration trust funds such as those administered by the Gulf Coast Ecosystem Restoration Council. Future directions emphasize interoperability with national data frameworks such as the National Phenology Network, enhanced modeling with inputs from NOAA’s National Centers for Environmental Prediction, and expanded collaboration with international initiatives like the International Union for Conservation of Nature and the Ramsar Convention on Wetlands-affiliated programs.
