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 2011 Horseshoe 2 fire caused intense flooding and soil erosion which led to stream sedimentation, infrastructure damage, and degraded watershed conditions in the Chiricahua Mountains region. To address this, partners engaged in a restoration project in burned (Tex Canyon) and unburned (Bar Boot Allotment) watersheds using in-channel loose rock erosion control structures.

State/Territory:

In May 2016, a 36-acre prescribed underburn was completed by BLM crew on the Marty and Peggy Main property near Trail, Oregon. The Main property is a 120-acre parcel consisting of low-elevation, dry, mixed conifer forest typical of the area. The overarching goal is to restore ecosystem processes and return the site to a more frequent, lower-severity disturbance regime.

This project was initiated in 1995 to develop the scientific basis for ecological restoration of southwestern forests and woodlands at both operational and landscape scales. The project worked specifically in four project areas in the Greater Mount Trumbull Ecosystem within the Grand Canyon/Parashant National Monument: piñon-juniper restoration, piñon-juniper herbaceous revegetation, cheatgrass abatement and monitoring, and ponderosa pine restoration.

University of Connecticut (UConn) received a permit to restore/ create wetland in compensation to mitigate the impact of its landfill disposal construction to adjacent freshwater wetlands. The remediation plan aimed to eliminate leachate discharge to surface waters while compensatory mitigation plan included restoration and creation of wetlands, vernal pool creation, and invasive and exotic plant species control.

State/Territory:

USIBWC and the USFWS collaborated on habitat improvements for fish and wildlife on the Rio Grande Canalization Project (RGCP). USIBWC implement habitat restoration at 22 sites covering 509 acres to reduce saltcedar and increase native riparian vegetation. Restoration also included mitigating channel maintenance activities that impacted vegetated islands.

In northern Vermont, the Vermont Fish and Wildlife Department (VFWD), Connecticut River Conservancy (CRC), and the U.S. Fish and Wildlife Service (USFWS) are working to restore and create riparian buffers to improve habitat for native fish and wildlife, strengthen streambanks, and retain sediment and decrease nutrient loading from agricultural runoff.

State/Territory:

The project is part of the St. Vrain Forest Health Partnership which is a collaborative of agencies and community members working to increase the pace and scale of cross-boundary forest restoration that provide infrastructure protection and public safety in the St. Vrain Watershed.

State/Territory:

Spring Peeper Meadow Wetlands Restoration Project (SPM) aimed to restore a 30-acre sedge meadow on a tiled cornfield. Invasive reed canary grass was eliminated in 1995, and 115 species of native wildflowers, grasses, and sedges were planted to restore the original plant community. Over 67,000 seedlings and transplants were systematically planted.

This project reconnected 965 acres of Columbia River floodplain to the lands and waters of the Steigerwald Lake National Fish and Wildlife Refuge. This reconnection reduces flood risk, improves terrestrial and aquatic wildlife habitat, and restores natural ecosystem functions. This project protects nearby communities from flooding that have consistently damaged properties. 

State/Territory:

The Karuk Tribe of California and the Six Rivers and Klamath National Forests worked on developing a programmatic approach to watershed restoration in the Karuk Ancestral Territory, an area that was degraded by past mining, excessive logging, and road building activities.

State/Territory:

To restore the rare riparian wetlands at the Rio Yaqui Basin, USFWS purchased conservation easements to protect water resources and increase connectivity of riparian and upland habitats. USFWS built trust with a local coalition of ranchers who support private land conservation. Two conservation easements were purchased: the 7,000-acre 99-Bar Ranch and the 13,713-acre Bar Boot Ranch.

State/Territory:

Funded by Bureau of Reclamation’s Central Arizona Project (CAP), this project focused on removing non-native Green Sunfish and Black Bulkhead to protect the native Roundtail Chub in Red Tank Draw. Biologists from the Arizona Game and Fish Department mechanically removed non-native fishes using backpack electrofishing, mini-hoop nets, Swedish gill nets, and snorkeling with spears.

State/Territory:

The Uncompahgre Plateau (UP) Project was formalized through a joint partnership of federal and state governments to restore the ecological, social, cultural, and economic value of the over 1.5 million acres of Uncompahgre Plateau. The primary UP programs are: Landscape Scale Project Planning, Invasive Species Management, a Native Plant Program, On-The-Ground Treatments, and Education and Technology Transfer.

State/Territory:

Country Acres Road- Richmond, Rhode Island, was once home to mixed temperate forest with seasonal freshwater wetlands before degraded by mining of sand and gravel and dominated by invasive plants. The goal was to restore the non-forested formerly mined acreage to native grass and wildflower meadow.

State/Territory:

The Valle de Oro National Wildlife Refuge (NWR) is an urban oasis for both wildlife and people. The Refuge aims to restore 530 acres of its land to native bosque (riparian woodlands) and upland habitat to support wildlife. The green spaces in the refuge offer communities opportunities for wildlife observation, photography, youth employment, and environmental education.

State/Territory:

In 1998, scientists from The Nature Conservancy implemented a tree-thinning experiment at Bingham Cienega Natural Preserve (the Preserve) to restore a bosque structure to a velvet mesquite community. The goal was to determine whether thinning could accelerate the development of a mature mesquite bosque.

State/Territory:

Since 2016, Audubon New Mexico has engaged in innovative environmental water transactions with four Middle Rio Grande Pueblos, a private golf club, several private water rights holders, and municipalities to support riparian habitats in the Isleta Reach during the driest time of the year.

Watergate Wetlands Restoration Project aimed to restore wetlands that were historically present at Delaware Water Gap National Recreation Area, and to restore the natural function of Van Campens Brook. Led by the National Park Service, the project involved draining constructed ponds and pumping water back into the brook through a sediment-blocking filter.

State/Territory:

The Wood for Life partnership (WFL) was a collaborative network of organizations in northern Arizona including the USFS, Navajo Nation, and Hopi Tribe. They are working to remove thinned fuelwood from restoration projects in the wildland urban interface (WUI) to reduce the risk of wildfires, and make the removed wood available for Navajo Nation and Hopi Tribe members.
