Wetlands don’t often come to mind when thinking about major metropolitan cities like Detroit. Bogs, marshes, vernal pools, and swamps contrast starkly with the city’s skyscrapers, roads, and industrial plants, and up to 90 percent of the area’s wetlands along the Detroit River have been lost since European settlement.
In addition to serving as picturesque areas for watersports and relaxation, wetlands serve many purposes.
“Wetlands are a pretty unique interaction between the landscape, its soils and hydrology, and under these conditions, provide a number of ecosystem services and creates unique habitats,” said Bill Shuster, Ph.D., a civil and environmental engineering professor at Wayne State University.
They provide habitats supporting thousands of birds, reptiles, amphibians, insects, fish, and plants. They are also important in nutrient transformation and carbon sequestration, which removes excess carbon dioxide from the atmosphere. They also provide important water filtration.
“When water enters a wetlands system and slows down any sediment that it’s carrying, it usually falls out of the water column,” said Dianne Martin, the director of ecological services with ASTI Environmental consulting firm. “So we can think of our wetlands… as ‘the kidneys of our ecosystem.’ They’re constantly just filtering and cleaning things out and sending water downstream in a better condition than it received it in.”
Arguably the most significant role that wetlands can play in the Metro Detroit area is managing excess storm runoff. Wetlands serve as sponges, absorbing excess water from heavy precipitation to prevent flooding, like the summer of 2021 when major flooding caused mass devastation, power outages, highway closures and sewage backups affecting more than 100,000 people.
The city and surrounding region are experiencing the consequences of that loss as climate change brings more rainfall.
“We lost that storage capacity a long time ago, but still, it’s coming back to haunt us,” Shuster said. “It would be awfully nice to have that storage capacity in that habitat and all of the valuable services that wetlands provide.”
Protecting Michigan wetlands
Today, governments, groups, and organizations are working to preserve and restore these crucial ecosystems.
Wetlands are protected in Michigan, especially if they are connected or close to one of the Great Lakes, Lake St. Clair or an inland lake, pond, river or stream or larger than 5 acres.
For wetlands that don’t meet these criteria, local municipalities are responsible for their protection, and cities like Rochester Hills, Oakland Township, Orchard Lake Village and West Bloomfield have regulations in place. In Detroit, wetlands are referenced in the zoning ordinance and refer to state regulations.
Friends of the Detroit River – a non-profit that works to protect the Detroit River – and partners have also undertaken long-term projects to restore the damage caused by wetlands loss around Belle Isle and the lower islands in the Detroit River.
Planning for the projects started in the 1990s, identifying around a dozen sites to prioritize and available partners. Implementation accelerated with the Environmental Protection Agency’s 2010 Great Lakes Restoration Initiative and funding from the Great Lakes Institute and the National Oceanic and Atmospheric Administration.
The projects have involved implementing protective structures and shoals – shallow areas in a body of water, like sandbars – around the islands to brace them from the waves and water fluctuations that lead to erosion.
While redeveloping the services once provided by lost wetlands can take decades, Bob Burns, the organization’s Detroit Riverkeeper and wetlands expert and vice chair of its Public Advisory Council, said they’ve already seen improvement, especially in Grosse Ile.

On Celeron Island, Burns said vegetation returned within a year of implementing shoals, and fish activity increased. Sugar Island was facing significant erosion due to waves, with trees falling into the water.
However, the organization recently completed a project that restored the shoreline, created an emerging wetland, and set up protections around the outer perimeter to break up waves. Already, they’ve seen the return of snakes, frogs, mink, muskrats, birds, and other wildlife.
“That would have all been washed out if we wouldn’t have been able to do that in the timeframe we did,” Burns said.
Wetlands protection is also part of the Southeast Michigan Council of Governments’ (SEMCOG) GREEN Initiative, which promotes sustainable environmental practices in the region. The plan aims to establish 500,000 acres of wetlands in Southeast Michigan by 2025, including preserving 337,000 existing acres and creating another 163,000.
“It’s a great goal, and even if we don’t come even close to that, anything that we can do, I think, is important because land isn’t going to be created any time soon,” Martin said. “What we have now is what we have; now is the time to protect anything we can. There are all sorts of mechanisms for doing so; it just needs to be an organized approach.”
