Nature-Based Solutions Case Study Search

This database contains over 400 implementations of nature-based solutions. Use the filters to identify the case studies most relevant to you.

While all cases here exemplify applications of NBS strategies, they were gathered from various sources and not all were written using the framing of nature-based solutions. To qualify as a nature-based solution, a project must provide benefits to both people and nature. In some instances, the human benefits are present but not emphasized in the case write ups; these cases were included because they still provide useful information to learn from.

Muskegon Lake’s shoreline and wetlands were severely degraded from industrial waste disposal, shoreline land use, and stormwater management. The Amoco Fish and Wildlife Habitat Restoration Project restored wetlands and wildlife habitat at a 9-hectare site. A constructed shoal system, the removal of a concrete wall, and a planted embankment restored wetland habitat.

The U.S. Army Corps of Engineers (USACE)–Detroit District and several other partners used Great Lakes Restoration Initiative funding to reconnect 340 kilometers of the Boardman River to Grand Traverse Bay of Lake Michigan. This project involved three dam removals over six years, and improved riverine habitat for important species.

Restoring Lake St. Clair, between Michigan and Canada, has been an international priority for decades. The Clinton River Mouth Wetland, at the edge of Lake St. Clair is the site of a restoration project headed by the U.S. Army Corps of Engineers. This project will remove invasive species and use dredged materials to create wetland habitat.

In Midland, Michigan a former ash pond for a coal-fired powerplant is located within the floodplain of the Tittabawssee River. Instead of the traditional (and expensive) cap and long-term maintenance plan, Dow's corporate nature team removed the ash and restored the area to a conservation wetland.  

State/Territory:

Galloway Creek, a tributary to the impaired Clinton River in Michigan, provides cold-water base flows that support trout species. Development led to a straightened, degraded, and disconnected creek that runs through a golf course. This project restored floodplain connectivity, improved geomorphic stability, and built in-stream habitat for fish species and aquatic wildlife. 

State/Territory:

The City of Ann Arbor recognized stormwater runoff as a growing threat to the quality of their water supply in the Huron River. To protect the city’s drinking water and reduce downstream impact of the pollution, they designed two financial incentives.

State/Territory:

USFWS led the Seney Peatlands Restoration Project to restore the hydrology and ecological integrity of the peatlands, wetlands, and streams affected by the Walsh Ditch in the Seney National Wildlife Refuge. Between 2002–2003, nine earthen ditch plugs were installed along a 4.5 km section of the ditch.

On the southeastern shore of Lake Michigan, the city of St. Joseph is vulnerable to flooding from storm surges. Residents and city officials recognized the need to build resilience and worked together to enact a "no-build" ordinance to help minimize coastal erosion and retain beach access.

State/Territory:

This project aimed to replace a 1,900-foot failing steel seawall and protect a shoreline walking path along the St. Clair River in Marysville, MI. The nature-based design, used to stabilize the roadway embankment and reduce erosion from wave action, included a large stone toe and an emergent wetland shelf/bench with over 10,000 native plants.
