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.

In northern Wisconsin, tribal foresters from the Menominee Nation are working to speed regeneration of more than 200,000 acres of forest areas that have been treated for invasive diseases like oak wilt. Their efforts are also creating forests that are better adapted to future conditions.

The Cat Island Chain in Green Bay, Wisconsin was lost to erosion and storms in the 1970s. This project is rebuilding the islands using clean dredged material from a nearby navigational channel. This will create beach and wetland habitat for many species and support both sport and commercial fisheries.

Curtis Prairie at the University of Wisconsin-Madison Arboretum is the site of the world's first ecological restoration project. Begun in 1936 by Dr. Theodore Sperry, the project has been ongoing for more than seventy years and has yielded a wealth of research data about the dynamics of tallgrass prairie ecosystems and the practices most effective in their restoration and management.

As Milwaukee’s population grew, it faced increased stormwater flooding and sewer system overflows. In 2001, the Conservation Fund and the Milwaukee Metropolitan Sewerage District (MMSD) launched a flood management program called Greenseams. The program protects wetlands and other lands containing water-absorbing soils by purchasing land and conservation easements from willing landowners.

The state of Wisconsin, with funding from the Environmental Protection Agency’s Great Lakes Restoration Initiative, used dredged material to create endangered Piping Plover habitat in the St. Louis River Estuary.  This project successfully established breeding habitat, removed dangerous shoaling sites near the Duluth-Superior Harbor, and increased bird-watching opportunities.
