The Mid-Atlantic Coastal Wetland Assessment

Functioning Landscapes

Remote Sensing

Landscape census surveys using satellite imagery and aerial photography identify trends in wetland extent and condition

Rapid Assessments

Field assessments of vegetation, soil, and disturbance are used to identify spatial and temporal trends in wetland condition

Station Monitoring

Fixed station monitoring tracks changes in physical, chemical, and biological conditions in relation to sea level rise and other stressors

About MACWA

The Mid-Atlantic Coastal Wetlands Assessment (MACWA) is the first wetland program to study tidal wetland health in our region. MACWA is a joint effort of two National Estuary Programs (The Partnership for the Delaware Estuary and Barnegat Bay Partnership) together with the Academy of Natural Sciences. MACWA aims to supply coastal managers with data to help plan wetland recovery and protection. MACWA consists of remote sensing analysis, rapid assessments, and fixed station monitoring of wetlands in the Delaware Estuary and Barnegat Bay, spanning three states: New Jersey, Pennsylvania, and Delaware.

About Fixed Station Long-Term Monitoring

Our monitoring program has focused on measures of marsh elevation change, using sediment elevation tables, analysis of water chemistry at fixed stations, analysis of soil quality, and plant above and belowground biomass. In addition our monitoring program has focused on change over time in wetland vegetation in fixed plots and along transects.

SETs

Marsh surface elevation and sediment deposition are monitored using the standard rod surface elevation table (RSET) protocol established by the U.S. Geological Survey

Read More

Wetland Elevation

Marsh elevation is surveyed relative to geodetic and tidal datums, producing an understanding of vulnerability to sea level rise

Read More

Water Quality

At a series of fixed stations, water is collected for field and laboratory assessments of salinity, dissolved oxygen, suspended sediment, and nutrient concentrations

Read More

Soil Chemistry

Soil cores are analyzed for soil bulk density, organic content, organic carbon content, nitrogen content, and phosphorus content

Read More

Plant Biomass

Plant biomass was collected once per year at peak biomass, including aboveground collections, as well as belowground collections using soil cores

Read More

Vegetation Change

At each site, a total of nine permanent quadrats have been established and plant community assemblages are characterized

The Barnegat Bay Partnership

The Barnegat Bay Partnership (formerly the Barnegat Bay National Estuary Program) is a partnership of federal, state, municipal, academic, business, and private organizations that work together with the communities of the Barnegat Bay watershed to help restore, protect, and enhance the natural resources of the Barnegat Bay ecosystem. It is one of 28 National Estuary Programs throughout the United States and is administered by the United States Environmental Protection Agency. The Barnegat Bay Partnership is a department of Ocean County College, a community college located in Toms River, New Jersey.

The Partnership for the Delaware Estuary

The Partnership for the Delaware Estuary (PDE) is a nonprofit dedicated to protecting the Delaware Estuary. The Delaware Estuary supplies clean drinking water for millions of people, and supports a booming industrial region; one that contributes $12 billion every year to our local economy. Our waterways and open spaces also provide plenty of free outdoor fun where you can hike the trails, fish the bay, watch wildlife, and paddle a creek! We bring together people, businesses, and governments to restore and protect the Delaware River and Bay. We are the only organization that focuses on the tidal River, from the head of tide at Trenton to the mouth of the Bay at the Atlantic Ocean.

The Academy of Natural Sciences

The Ruth Patrick Center for Environmental Research at ANS has been devoted to understanding, protecting, and restoring the health of watersheds since 1947. It consists of a multidisciplinary group of environmental scientists and engineers focused on understanding aquatic and terrestrial ecosystems and applying this knowledge to assess ecosystem health and develop watershed-level strategies for enhancing environmental quality. The Patrick Center also works with diverse stakeholders, including government, community groups, industry, and environmental organizations to improve environmental stewardship.
