Coastal marsh adjoining Saginaw Bay, part of a much larger network of high quality emergent cattail habitat. At the Rifle River mouth.
Hosts a good variety of emergent marsh breeders, including 4 conservation concern species including American and Least Bitterns, Marsh Wren, and Black Tern.
About 30% of the IBA is part of the Wigwam Bay State Wildlife Area. The remainder is presumably public ownership as it is wet marsh adjoining Saginaw Bay.
Mostly emergent marsh (cattail and bulrush), shrubland, with a variety of other negligible cover types.
Primary land use is wildlife conservation. Recreational activities and commercial fishing are secondary uses.
