Its abundant marshes, shallow lakes and extensive grasslands offer significant nesting, feeding and migration staging habitatfor waterfowl, shorebirds and others. Cryptic marshbirds nest on the marhes, and uplands offer nesting habitat for a number of declining neotropical migrants. It also is a candidate for future DNR designation as a nationally significant Bird Conservation Area.
