The Chiwaukee Prairie-Illinois Beach Lake Plain is a stretch of connected natural areas on the western shore of Lake Michigan which spans across the Wisconsin-Illinois Border. The Lake Plain includes Kenosha Dunes, Chiwaukee Prairie State Natural Area, Spring Bluff Forest Preserve, Illinois Beach State Park, Hosah Park, and Waukegan Dunes and serves as the highest quality dune and swale ecosystem in the Chicago Region. The Lake Plain Collaborative, formally established in 2010 through MOU, is a concerted effort between state and local agencies, universities, non-profits and other organizations and individuals seeking to manage and protect the Lake Plain as one ecological unit. The Lake Plain Collaborative is now a widely recognized  alliance which cooperatively secures grant funding and fosters coordinated management and conservation efforts across the state line.
