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 Chaparral Lands Conservancy is conducting a project to restore and enhance imperiled vernal pools and species on a City of San Diego preserve in Proctor Valley, which has been degraded by off-road vehicle activity. The Valley contains unique and imperiled vegetation, including coastal sage scrub, vernal pools, native grasslands, and chaparral, as well as numerous rare species.

The Texas Parks and Wildlife Department (TPWD) and the Borderlands Research Institute (BRI) in Alpine, Texas, collaborated with local landowners to prioritize areas for pronghorn-friendly fence modifications. The team removed old, unused fences and accompanying fence posts, and adjusted the height and bottom strand of existing restrictive fences to allow pronghorn passage.

Coral reefs off the west coast of Maui are readily accessible and heavily used by visitors and locals alike. To restore declining reef habitats suffering from excessive algae growth, Hawai’i Department of Land and Natural Resources implemented a herbivore protection plan that restricts extraction of herbivorous fish and invertebrates from the reefs.

To restore the endangered Silvery Minnow, the Bureau of Reclamation, U.S. Fish and Wildlife Service, and the Save Our Bosque Task Force worked closely with a local landownerto restore approximately 0.8 river miles of critical habitat along the Rio Grande River. The project involved mechanical bank lowering and the creation of side channels and embayments.

The Puyallup River in Washington state is channelized and disconnected from its floodplain due to levee construction and logging in the region. This has led to habitat degradation for important fish species and a higher risk of flooding and damage to important transportation infrastructure. This project will reconnect over 28 hectares of the floodplain.

In 1990s, state, federal, and tribal agencies executed a cooperative agreement to launch the SJRBRIP to conserve and recover Colorado Pikeminnow and Razorback Suckers in the San Juan River Basin while meeting water needs of the local communities. The primary focus of the project went to mechanically removing nonnative fish (especially Channel Catfish) via electrofishing.

After the 2018 Martin Fire, the USDA and the Nevada Department of Wildlife completed a restoration project on public and private land to rehabilitate the burned rangeland. Using herbicide and previously tested experimental seed mixes, the project sought to control cheatgrass and establish both native and non-native perennial plant species to lessen the long-term wildfire damage on the rangeland.

This project restores river flow to 11.25 miles of secondary channel habitats in the lower Mississippi River through the construction of 11 notches in 8 dikes, 1 chevron, and 2 roundpoints. This project, located outside of Memphis, TN, greatly improves recreational opportunities and increases habitat availability for 3 federally listed species.

Planned and implemented by the Tribe’s Fish and Wildlife Department, this unique program of watershed restoration and riparian conservation has been rooted in traditional Zuni cultural values. The causes of degradation were man-made dams, channelization, and invasive plant encroachment (i.e. Tamarix pentandra). The project reintroduced 23 beavers to sites with impaired hydrologic flow regimes.

State/Territory:

Human development and climate change have led to the loss of wetland vegetation and altered hydrology in the Amargosa River watershed. This project conducted scientific research to support the conservation of the Amargosa vole population and the restoration of their wetland habitats.

State/Territory:

Scientists from USGS conducted research to study the ecological factors that facilitate bullfrog spread in the Yellowstone River and tested suppression methods. They conducted habitat modeling and detected 58 sits along 107 km of the river. Multiple field techniques were used to remove bullfrogs at various life stages from sites identified with bullfrog breeding.

The Blue River Native Fish Restoration Project aimed to establish and secure populations of native fish in the Blue River Tributary of the upper Gila River Basin. The project involved a 3-step process: 1) building a fish barrier, 2) eliminating non-native fish using mechanical techniques, and 3) translocating and monitoring native species in the lower Blue River.

Batiquitos Lagoon’s diverse ecosystems was degraded in the 20th century because of heavy agricultural and residential, and transportation runoff. Restoration efforts began in 1997 by local government. Major constructions involved dredging sand from central basin for beach replenishment (1994 – 1995) and placing fine sediment materials from the western into central basin to construct lagoon mouth jetties (1995 – 1996).

State/Territory:

Between 1890 and 1940, extensive logging using narrow-gauge railroad technology cut over much of the Bluewater watershed. Led by USDA Forest Service, this project implemented a range of channel treatments and interventions to affect flow regimes, channel stability, and water quality, including not only dams and control structures but also riparian plantings, riparian pastures, and beaver management programs.

The goal for restoration of the marsh located on the campus of the Rocky Hill School along the Potowomut River in East Greenwich, RI is to improve habitat for a recently discovered population of diamondback terrapins (Malaclemys terrapin). The project assembled a dataset and developed a plan to restore the marsh to increase diamondback terrapin nesting habitat.

Tampa Bay was designated an "estuary of national significance" by Congress in 1990, paving the way for development of a long-term blueprint for bay restoration through the Tampa Bay Estuary Program. A long-term restoration plan was made in restoring coastal wetlands and benthic habitats, including 1,000 hectares of seagrass beds.

Until it was added to Red Rock Canyon State Park in 1989, the South Flat area had been heavily used by off-higway vehicles (OHVs) as a campground with large motor homes, leading to significant vegetation damage. The project goal was to revegetating the area with perennials.

Rising temperatures threaten coral reefs, which dissipate wave and storm energy to protect nearby shorelines for nearly 200 million people worldwide. To enhance coastal protection, this novel project will identify thermally tolerant coral stocks, propagate in nurseries and outplant at three sites on O’ahu, Hawai’i.

Bat Conservation International (BCI) funded the project to increase the number of flowering agaves along the migratory route of nectarivorous migratory bats in the Southwestern United States and Northern Mexico. Through the binational collaboration, the team protected and enhanced existing agave habitats and planted new agaves throughout the migratory corridor.

The Bolsa Chica wetland restoration was the largest coastal wetland restorations ever undertaken in Southern California (Amigos, 2008). The project restored full and muted tidal wetlands function to almost 600 acres of the Bolsa Chica Wetlands that were degraded by agricultural and urban development.
