Brunswick Town–Fort Anderson is an important historic site on the North Carolina coast. To prevent further erosion and negative impacts from storms and sea-level rise, the North Carolina Department of Natural and Cultural Resources installed 140-meters of Reefmaker along the shoreline. This stabilized the shoreline and produces multiple co-benefits.
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.

The Las Cienegas National Conservation Area in Arizona is home to five of the rarest community types in the American Southwest. Managers constantly combat woody-shrub encroachment onto valuable grasslands, specifically the species velvet mesquite (Prosopis velutina). The Bureau of Land Management and the Nature Conservancy partnered to evaluate the condition of resources and to review monitoring protocols.
Buffalo Slough Island in Sturgeon Lake is home to important cultural resources for the Prairie Island Indian Community (PIIC). The island was experiencing erosion and habitat loss, until the U.S. Army Corps of Engineers and the PIIC signed a project partnership agreement to restore the island.
Saguaro National Park, in the Sonoran Desert near Tuscon, Arizona, is threatened by invasive perennial grasses. These grasses outcompete native plants and heighten the risk of wildfires, a disturbance that the park’s ecosystem is not adapted to. Park managers want to remove invasive grasses and restore native species landscapes.
A manufacturing company purchased 100 acres of abandoned golf course on floodplain of Fort Collins to develop its new headquarter. To reduce the frequency and severity of flooding, the company reconnected the Cache la Poudre River with its floodplain, removing fill from 31 acres to build up pads for properties.
The West Fork San Luis Rey River on Palomar Mountain, in Southern California hosts a population of native Coastal Rainbow Trout (Oncorhynchus mykiss irideus) that were threatened by the invasive Black Bullhead (Ameiurus melas). After two years of work, biologists from the California Department of Fish and Wildlife achieved complete bullhead eradication within this stream.
BLM is leading the construction and maintenance of a system of up to 11,000 miles of strategically placed fuel breaks to control wildfires within a 223-million-acre area in the Great Basin that includes portions of Idaho, Oregon, Washington, California, Nevada and Utah. Fuel breaks would be implemented along roads or rights-of-way on BLM-administered lands.
A team of nonprofit organizations and government agencies led by the California State Coastal Conservancy developed preliminary design plans to use a gravel beach and berm in the Eden Landing Ecological Reserve to protect critical habitat, control erosion, and enhance shoreline resilience on the south San Francisco Bay.
Camden County, New Jersey frequently experiences combined sewer flooding during intense rain events. Camden SMART Initiative, a partnership of local government, state environmental agency, local universities and local nonprofits, promotes a network of green infrastructure programs and projects throughout the county. Projects like urban greening, rain gardens and stream daylighting were implemented.
Cape Lookout State Park, located in coastal Oregon, experienced extreme erosion and storm damage to its beach and infrastructure. Instead of a less aesthetic, more expensive, seawall or revetment, managers opted to build a cobble berm backed by an artificial dune to increase coastal protection and enhance the natural shoreline community.
The San Clemente Dam on the Carmel River was no longer useful due to sedimentation of the reservoir, and was declared a public safety hazard in the 1990s. This project removed the dam and restored the Carmel River’s floodplain and habitat. This improved habitat and connectivity for wildlife, including the threatened steelhead.
Cat Island and Ship Island are barrier islands off the coast of Mississippi that provide protection to coastal communities from erosion and storm surges. This project used millions of cubic meters of sand and reused dredged sediment to restore the islands’ beaches and dunes.
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.
Planning with extreme weather thresholds catalyzes a $400,000 green infrastructure investment in a historically underserved neighborhood in Las Cruces, New Mexico. City staff partnered with NOAA and nonprofit organizations for a local resilience project that includes a demonstration rainwater harvesting facility and a green infrastructure assessment of the neighborhood.
Due to extreme flooding events and excessive nitrogen levels in the Cedar River Watershed, the City of Cedar Rapids led the Middle Cedar Partnership Project to reduce nutrient runoff and improve soil health. The partnership collaborated with local farmers, landowners, and conservation organizations to implement strategies to reduce nutrient runoff, mitigate flood risk, and improve soil health.
Florida’s Charlotte Harbor Estuary was established as national estuary under the 1987 National Estuary Program for its significance to wildlife and local economy. A 20-year Comprehensive Conservation and Management Plan (CCMP) was formulated to restore and protect the estuarine system. Restoration activities started in June of 2001
Plum creek is a primary tributary to the Chatfield Reservoir, a major source of water for Denver, Colorado. Urban development and increased stormwater runoff disrupted the creek’s sediment dynamic, causing streambed degradation and loss of wetlands. This project restored Plum Creek and its riparian habitat to increase water supply and protect native species.
A collaborative effort from USFWS, USDA, and Maryland DNR has worked over 20 years to eliminate the exotic, invasive nutria, which, combined with sea level rise and land subsidence, have caused over 5,000 acres loss of wetlands. Working closely with public and private landowners, the project managed to remove 14,000 nutria and protect over 250,000 acres of marshes.
As part of an EPA study and initiative to combat the urban heat island effect and to improve urban air quality, Mayor Richard M. Daley and the City of Chicago began construction of a 38,800 square foot (total roof area) semi-extensive greenroof in April 2000.
To eradicate the Asian longhorned beetle (ALB), in 1999, USDA and USFS developed a 10-year plan in 1999 that follows five stages: phase-in, delimitation, and containment; suppression and control; deregulation; and eradication. All infested trees were either removed and replaced by non-ALB host trees on a one-to-one basis or treated with the insecticide Imidacloprid via trunk or soil injection.
