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 2002, local, state, and federal partners collaborated to form the Virgin River Resource Management and Recovery Program (VRP) in order to address the threats to native fish species by eradicating invasive Red Shiner. VRP partners constructed three fish barriers on the mainstem Virgin River and applied piscicide (rotenone) treatments.

To restore native amphibian populations decimated by non-native American bullfrogs (Rana catesbeiana), a collaborative team of researchers, managers, and technicians (Frog Team) has been conducting mechanical removal at a landscape-level across southern Arizona. Since 1990s, the frog team has removed bullfrogs in a prioritized project area of 10,230 square miles and reestablished the native Chiricahua leopard frog populations.

The Lower Red River Meadow Restoration Project is a multi-phase ecosystem enhancement effort designed to restore a section of the river's natural channel design and revegetate adjacent riparian areas with native species in order to restore natural physical and biological functions and thereby create high quality habitats for fish and wildlife.

Non-governmental organizations Borderlands Restoration (BR) and Gila Watershed Partnership (GWP) led the Madrean Archipelago Plant Propagation (MAPP) Initiative to coordinate seed collection, curation, and production of plant materials with on-the-ground restoration in the Sky Islands. MAPP created a database to track seed collection, propagation, and outplanting data, and coordinated seed collection efforts with the BLM and NPS.

Masonboro Island, NC contains a back barrier tidal marsh that is unable to maintain a healthy elevation as sea-level rises. This project examined the effect of placing dredged material on the microtidal marsh environment. Thin-layer placement increased stem densities and can be used to mitigate effects of degrading marshes.

The Mount Rose Preserve Forest Restoration Project aimed to (1) re-establish the forest, shrubland, and meadow habitats, (2) innovate and communicate locally appropriate forest restoration practices, and (3) restore existing plant species through the exclusion of white-tailed deer and invasive plant species.

State/Territory:

This project will test the oyster recruitment and growth ability of different types of cultch material in Mobile Bay, Alabama. Oyster density and growth has declined in Mobile Bay due to damage from hurricanes and increases in oyster drill populations. This project will restore reef and help inform future restoration project materials.

USFWS established the Sevilleta Long Term Ecological Research (LTER) to research fire management with prescribed burns in semiarid grasslands at Sevilleta National Wildlife Refuge (SNWR). The effect of prescribed burns and timing on organic matter, ammonium, and nitrate was measured. Results suggest that seasonality affects plant species productivity and composition.

Before the national park was established, Acadia’s wetlands have been dredged, ditched, or filled in, making them susceptible to invasive species, among which glossy buckthorn (Frangula alnus) has become a particular threat. The NPS led the efforts for finding, removing, and researching invasive species in Acadia.

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.

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.

State/Territory:

The project aimed to restore riparian grass and sedge meadows currently dominated by Artemisia tridentata var. Tridentata. The project also served as research to study the effect on soil water and temperature, plant species establishment, and abiotic responses by water table depth, burning, and Artemisia. All Artemisia was killed as a result of the burn.

State/Territory:

This project is a five-year program that restored the abandoned landing strip and tank trail at the Vertical Short Takeoff and Landing (VSTOL) site. The project tested various procedures such as site preparation, soil manipulation, irrigation methods, and plant protection to develop the most efficient methods for the restoration of native plant communities in disturbed areas while simultaneously controlling erosion and dust.

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.

The Dixon Water Foundation employs grazing techniques that mimic historical bison movements to rehabilitate the Chihuahuan Desert grassland from the impacts of overgrazing, which have led to increased erosion, runoff, reduced aquifer recharge, and carbon sequestration. Such rotationally grazed practices improve soil health as cattle fertilize soil with manure and break up surface to allow seeding and water infiltration.

The National Aquarium in Baltimore is working with the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, Maryland Conservation Corps, the Friends of Blackwater and community volunteers to restore 10 acres of salt marsh in the northern and central portions of Barren Island.

State/Territory:

The coast of Orange County, California, one of the few remaining tidal salt marshes in Southern California, is threatened by global sea level rise and local subsidence. Concerned by USGS’s modelling results of marsh loss, county managers and refuge managers collaborated to use county’s dredge sediment from an adjacent waterway to build up the refuge’s salt marshes.

Researchers from the University of Texas Rio Grande Valley partnered with The Peregrine Fund and USFWS to evaluate grassland management strategies that address honey mesquite and huisache shrub encroachment in the Bahia Grande coastal prairie, with the goal of protecting the habitats for endangered falcon populations.

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.
