Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Models

As part of the Great Lakes Coastal Wetland Restoration Assessment (GLCWRA), models are being developed to support the identification and restoration of potential coastal wetlands (i.e., areas that could become coastal wetlands if hydrologically connected to the Great Lakes) along the U.S. coast of the Great Lakes. The GLCWRA uses principles of geodesign to identify areas along U.S. coast of the Great Lakes that have the most potential to restore coastal wetland habitat. 

The following first three GLCWRA models focus on a pilot area identified by the Upper Midwest and Great Lakes LCC coastal working group:

  • Western Lake Erie Restoration Assessment (WLERA): Lake Erie between the mouths of the Detroit River, MI and Black River, OH.
  • Connecting River Systems Restoration Assessment (CRSRA): connecting channels area that includes the Detroit River, Lake St. Clair, and the St. Clair River
  • Saginaw Bay Restoration Assessment (SBRA): shore of Lake Huron from the St. Clair River through Saginaw Bay. 

All three of these assessments are visible on dynamic, interactive, and GIS-based web-based mapping applications.
