Horicon Marsh:

This vast wetland is both a State Wildlife Area and a National Wildlife Refuge. Originally established as habitat for migrating and nesting ducks, it has since become a stopover for Canada Geese.

Today, Horicon Marsh is increasingly recognized and managed as a wetland ecosystem for all of its plants and animals. Horicon Marsh has been designated as a Wetland of International Importance by the Ramsar Convention and a Global Important Bird Area by the American Bird Conservancy. No group of wildlife better represents the vitality of this marsh better than its birds. Over the years, a total of 304 species of birds have been sighted on this marsh.
