ECOLOGICAL VALUE OF THE HUMBUG COMPLEX

Environmental Setting Ecological and Natural Resource Values of Humbug Marsh Habitat Description Fisheries Special Species Waterfowl Birds Plants Other Birds and Notable Species Observed at Humbug Links to other reports on Humbug Humbug Home The Humbug Complex is made up of Humbug Island, Humbug Marsh, and adjacent undeveloped upland habitats. It includes 465 acres of unique fish and wildlife habitats in Gibraltar, Michigan. Humbug Marsh represents the last mile of natural shoreline on the U.S. mainland of the Detroit River. Over 97% of such coastal wetlands in the river have been destroyed by shoreline development and nearly all of such coastal wetlands in western Lake Erie have disappeared during the past 50 years. Because they are home to such a high diversity of fish and wildlife, such marshes have been identified by The Nature Conservancy as globally unique and globally significant in biological diversity - nothing like this marsh exist anywhere outside the Great Lakes. Purpose: Clearly communicate the ecological significance of the Humbug Complex.
