Sea Level Affecting Marshes Model (SLAMM)

The Nature Conservancy, Rhode Island Chapter

These data represent projected potential impacts to salt and brackish marsh under future scenarios of 1, 3, and 5 feet of sea-level rise as compared to the initial condition in 2010. These potential changes to marsh habitat were identified by the implementation of the SLAMM 6.1 model, an analysis that was funded through a National Oceanic and Atmospheric Administration (NOAA) Coastal and Climate Applications (COCA) grant.

These data are meant to aid in the assessment of the likely impacts of sea-level rise to coastal salt marshes in Rhode Island. The identification of suitable upland corridors for salt marsh migration can aid state and local agency decision makers and conservation groups in developing adaptive climate change strategies to provide resiliency for critical coastal habitats and important abutting upland areas.
