Over the past half century, human activity surrounding the Great Lakes basin has significantly degraded habitats and water quality, and as a result, many marsh bird populations are in steep decline, with some regional population declines as high as 80% in recent decades. Given the urgent need to protect and restore remaining coastal wetlands for wildlife and people, we developed a spatial prioritization to identify the most important U.S. coastal wetlands for 11 species of marsh birds representing high-quality wetland habitat--Marsh Wren, Pied-billed Grebe, Sandhill Crane, Swamp Sparrow, Virginia Rail, American Bittern, Black-crowned Night Heron, Common Gallinule, Least Bittern, Sedge Wren, and Sora. Utilizing bird data from the Coastal Wetland Monitoring Program
as well as wetland habitat conditions that determine suitability for these birds, such as the amount of emergent vegetation we were able to rank wetlands within 30 km of the shoreline based their importance to each of the 11 species.
The model’s results guided our selection of the regions of the Great Lakes coastal wetlands in which we undertake conservation action. Then we can examine these regions to identify key landowners and stakeholders of the specific high priority wetlands. This level of specificity allows us to be more proactive and effective in our partnership development, outreach, and project planning in high priority regions such as: the St. Louis River Estuary, Green Bay, the Calumet Region, St. Marys River, Detroit and Lake St. Clair, Saginaw Bay, Western Lake Erie Basin, Buffalo, Rochester, Sodus Bay, and Eastern Lake Ontario.
