The coral communities in Culebra were stressed by recognized erosion from an unpaved parking lot and road that had increased the volume of post-rainstorm runoff carrying pollutants. Community members managed to slow the flow of rainwater through erosion and sedimentation control, reforestation and habitat restoration through dune restoration, restoration of the line permanent vegetation, and delineation of vehicular and pedestrian access.

Nature-Based Solutions Roadmap 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.

The Sonoran Desert ecosystem was degraded by agricultural development and groundwater pumping from the 1930s to 1970s. This project sought to restore the lowland desert by reestablishing perennial shrubs. The team determined historic species composition on a study site, acquiring seeds of those species, introduce them to the site, and provide them with extra water for establishment.
The Trinity River basin has been degraded by human activities for almost two hundred years, leading to a decline in available salmonid habitat and populations. The Trinity River Restoration Program (TRRP) was created in 2000 to restore salmon and steelhead populations. The project also aims to restore the river through flow management, streambank restoration, and riverbed improvement.
In 2001, downtown Houston, Texas, faced an historic 1,000-year flood as a result of Tropical Storm Allison, shutting down the 700-acre Texas Medical Center Complex. While rebuilding the Center to withstand future floods, Texas Medical Center implemented a stormwater management plan that increases green space and improves water absorption through advanced landscaping techniques and permeable paving systems.
Ah Pah Creek is a fourth order stream with a 16.3 square mile watershed composed entirely of steep, forested land that was degraded by road and highway construction. Yoruk Tribal Fisheries Program (YTFP) and the California Conservation Corps (CCC) collaborated to address riparian restoration needs within the drainage, including extensive riparian conifer planting in its three major tributaries.
In Florida's humid climate, strawberry growers are in a constant battle with two kinds of fruit rot. Using a decision support system, they can save money by spraying fields only when the plant diseases are a threat, saving up to $400 per acre per year.
After years of hard work by American Rivers and its project partners, the Bloede Dam in Maryland’s Patapsco River was successfully removed in 2018, restoring 52.5 miles of the river’s natural flow and more than 65 miles of native fish spawning habitat. Removing the dam also strengthened community resilience, improved public safety, and facilitated increased sediment transport to marshes and beaches along the Chesapeake Bay.
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 Yakima Basin Integrated Water Resource Management Plan is a 30-year, $3.8 billion plan that restores ecological integrity to the region and provides assurances for meeting agricultural water needs even in the face of ongoing climate change. The plan includes key elements to help protect, mitigate, and enhance fish and wildlife habitat and improve the reliability of the region’s water supply.
In 2007 the Anacostia Watershed Society (AWS) initiated an experimental research project, called the 38th St. Bridge Project, on the rip-rap slope along the streambanks in order to demonstrate an alternative to the county's annual mowing-and-spraying of herbicide to control invasive species along the streambank.
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.
Greater sage-grouse (Centrocercus urophasianus) populations are declining in Utah and other western states due to the degradation of their seasonal habitats from the encroachment of pinyon-juniper trees. This project evaluated the ecological viability of using "lop and scatter" methods to mechanically remove encroaching PJ trees to manage sage-grouse winter habitat at a study site in Ashley National Forest.
Encompassing some of the wildest and least populated territory in the state, the Klamath region of Northern California faces threats from invasive species in its wildland ecosystems. To protect the forests and rivers, restoration efforts began by applying county-scale mapping tool to identify and treat high-priority eradication target.
The Apache-Sitgreaves National Forest (ASNF) utilized over 25 million funding from the American Recovery and Reinvestment Act (ARRA) to support projects that increase local employment, support forest restoration and fire mitigation, and boost local economy. Projects included forest restoration and fuels reduction, recreation and related road improvements, forest fire rehabilitation efforts, and greenhouse construction on the Fort Apache Indian Reservation.
Arden Park is along Minnehaha Creek, an impaired waterway that is a tributary to the Mississippi River. This park is in a highly developed suburb just south of Minneapolis (Edina). This project improved the park and restored a section of the creek, improving habitat, water quality, and recreation opportunities.
City of Arlington constructed a 21-acre stormwater wetland park to treat stormwater from Old Town Arlington, clean backwash water from the City’s water treatment plant, and reclaim water from the City’s Water Reclamation Facility before infiltrating or discharging into the Stillaguamish River.
The Ash Meadows National Wildlife Refuge (NWR) was established in June of 1984. The project aimed to restore the restore spring sources and outflow channels and associated riparian habitats that were previously degraded by agriculture, road-building, and water diversions, and now were dominated by invasive species.
Along the Morro Bay, the wetlands, intertidal mudflats, salt and freshwater marshes, eelgrass beds host some of the most productive natural habitats in the world. To protect the ecological significance of estuaries, stakeholders of the Morro Bay National Estuary Program in California worked with resources from the EPA's Climate Ready Estuaries program to identify their climate risks.
This project is assessing the role of Woody-Plant Encroachment and brush management on the carbon cycle, carbon storage potential, biodiversity, and rangeland ecosystem stability and resilience. Data collected from this project can inform land managers on costs and benefits of different brush management options and factors.
This project, implemented by the NC Division of Water Quality and NC Division of Forest Resources, aimed to reduce nitrogen and mercury loading of downstream waters in the Albemarle/Palmico estuary system by restoring wetland hydrology and native bog vegetation to a 640-acre research area. Activities included installation of water-control structures and replanting 100,000 trees.
