Humbug Marsh, a 1.88km2 wetland in southeastern Wayne County, Michigan, is a constituent element of the Detroit River International Wildlife Refuge. It is listed as a Ramsar wetland of international importance.[1]
Although Humbug Marsh is located within heavily populated Metro Detroit, it is acclaimed as a high-quality remnant of the wetlands that once lined both sides of the international Detroit River. This slow-flowing river was a hotspot of biological diversity, particularly as a location for fish spawning. The remnant marsh is classified as a place of "importance to threatened, endangered, and vulnerable species and ecological communities."[1]
Humbug Marsh is located on the Downriver shoreline of the Detroit River, straddling the boundary line between Gibraltar and Trenton in southeastern Wayne County, Michigan. A small offshore island (Humbug Island) is included within the official boundaries of the marsh.[1]
The Humbug Marsh parking lot is located at 5437 West Jefferson Avenue, Trenton, Michigan.[1]
