Synthesis of Salt Marsh Monitoring Data from Four New England NERRs

Data Resource
July 2020

The 2018-2019 catalyst project Synthesizing Monitoring Data to Improve Coastal Wetland Management Across New England compiled salt marsh monitoring data from four New England National Estuarine Research Reserves (Great Bay, Narragansett Bay, Waquoit Bay, and Wells). These data were collected as part of the NERRs System Wide Monitoring Program to help manage local and regional salt marshes.

The project generated the following four statistics-ready data packages. These regional databases compile data from all New England reserves from the years 2010 to 2018. Data were re-formatted, standardized, and underwent QA/QC. Data packages are provided as Excel workbooks, each containing metadata.

  • Regional Vegetation Template and Dataset - Vegetation data including cover, density, and height. Includes normalized and regression transformations of point intercept data to ocular cover and data formatted for PRIMER software.
  • Regional SET Template and Dataset - Surface Elevation Table (SET) data.
  • Regional Elevation Template and Dataset
  • Regional Water Level Template and Dataset

The project also produced reserve-specific data packets for the four New England reserves (Great Bay, Narragansett Bay, Waquoit Bay, and Wells). Each includes the reserve's re-formatted vegetation, SET, elevation, and water level data, as well as parameters and metrics unique to the reserve. For questions about their monitoring programs and related data, please see metadata tabs included in Excel workbooks or directly contact reserves.
