Where are Great Lakes Coastal Wetlands?
Great Lakes coastal wetlands are defined as an area of wetland directly influenced by the waters of one of the Great Lakes or its connecting channels. Great Lakes coastal wetlands are found throughout the basin, along shorelines, in the mouths of tributaries, and along connecting channels (Figure 1). There are greater than 500,000 acres of coastal wetlands across the Great Lakes basin. Seventy percent of the Great Lakes coastal wetlands are located within the United States, of which 73% are in the state of Michigan.
 See Figure 2.Coastal wetlands experience many stressors relating to human development, fragmentation, drainage, point and non-point pollution, and invasive species. Today, less than 50% of historic Great Lakes coastal wetlands remain.
Great Lakes Coastal Wetland Restoration Assessment is conducting efforts to identify previous existing wetlands and their restorability. Increasing threats to Great Lakes coastal wetlands emphasize the need for protection and restoration.The
