  • The Great Lake coastlines have extensive coastal dunes on Lakes Michigan, Huron and Superior. Some of the dunes have been designated as critical dune areas, approximately 74,000 acres along 265 miles of coastline. Critical dune areas represent a diverse cross-section of dune shapes, height, and vegetation along Lake Michigan's shoreline in the lower and upper peninsulas, and the shore of Lake Superior. The designated dunes include public lands and private properties where developmental, silvicultural, and recreational activities are regulated. A permit is required for those activities which significantly alter the physical characteristics or propose a contour change in a critical dune area.
