In response to the increased wildfire risk and spread of invasive species, the Sandia Pueblo Environment Department and ranch staff from Galloping Goat Pumpkin Patch Ranch, with funding from the Forest and Watershed Restoration Act through the New Mexico State Forestry Division, implemented a goat grazing program in 2021.

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.

This project created 335 acres of marsh and 28,342 linear feet of earthen containment dike in Bayou Grande Cheniere, Louisiana. This project utilized sediment materials from the Mississippi River borrow areas. This marsh and containment dike will enhance biodiversity and coastal protection from erosion and wave action.
For over ten years, the Tucson Audubon Society has collaborated with Audubon Southwest through the Important Bird Area (IBA) program to develop a protocol that protects the Chestnut-collared Longspur (Calcarius ornatus; CCLO). They monitored the CCLO population through volunteer-led in-person surveys and audio recordings, analyzed the conditions of cattle tanks, and documented the presence of invasive Lehmann’s lovegrass.
The native Guadalupe Bass had become locally extirpated in the San Marcos River and its tributary due to hybridization with non-native Smallmouth Bass, habitat degradation, and reduced water availability. With funding from the National Fish and Wildlife Foundation (NFWF), Texas Parks and Wildlife Department (TPWD) led a project to restore the native Guadalupe Bass population
In Colorado, the City of Boulder’s Open Space and Mountain Parks (OSMP) department engaged in ongoing efforts to remove cattails and manage American bullfrogs to protect the native northern leopard frogs (NLF) from predation, competition, and disease transmission. Since 2015, ecologists have mechanically removed approximately 500 adult bullfrogs from 10 NLF habitats.
A partnership between the BLM, Sacramento Water Forum, and USFWS is working to restore spawning conditions and salmonid habitats in the Lower American River downstream of the Folsom Dam. The plan focuses on enhancing gravel habitat, adding woody material, and creating side channels and floodplains for spawning and rearing Chinook salmon and steelhead.
Led by USACE, the Bosque Wildfire Project was initiated to restore bosque habitat and wetland function around Albuquerque, New Mexico. Key features of restoration included constructing wetlands and swales to support moisture-seeking plants and animals, creating high-flow channels and bank terracing to enhance hydraulic connectivity within the bosque, and revegetating with native plants.
The Healthy Forest, Health Wildlife project aimed to restore the understories of reclaimed forests. Between 2017 and early 2019, restoration efforts included invasive species removal, native plantings, and constructing animal shelters. In total, 288 shrubs, 564 herbaceous plants, and 348 trees were planted, in addition to herbaceous plant seedling at 46 seeds per square foot and 360 canopy tree seedlings.
In 2017-2018, Sky Island Alliance (SIA) developed and implemented a climate-informed process to restore pollinator population in riparian corridors of the Sky Island region. The goal was to increase pollinator forage, shelter, and continuity across the landscape while promoting biodiversity and ecosystem function.
Land managers from the Texas Parks and Wildlife Department (TPWD) are working to restore grassland habitat through the removal of western honey mesquite surrounding Calamity Creek of the Elephant Mountain Wildlife Management Area (EMWMA). They implemented two herbicide treatment plans through Individual Plant Treatment (IPT) and aerial application.
Horner Park is a 14-acre restoration area along the north branch of the Chicago River. This is a part of a larger goal to reconnect sustainable habitat along the Chicago River. Hydrogeomorphology, native plant communities, and riparian buffers were restored at this site.
Fishery biologists and park managers from the Native Fish Ecology and Conservation Program in Grand Canyon National Park are taking a holistic approach to expand the abundance and distribution of Humpback Chub within the park. They removed non-native Brown and Rainbow Trout via fishing and electrofishing, and then translocated Humpback Chub to three Colorado River tributaries.
The Walnut Gulch watershed in southeastern Arizona has experienced shrub encroachment that caused erosion and reduced infiltration on grasslands. Researchers at the University of Arizona and at the Agricultural Resource Service conducted an experiment to investigate the effectiveness of herbicide treatments in reducing woody species abundance and their impact to vegetation, runoff, and soil loss.
Historical military-base landscape in Kansas introduced non-native ornamental shrubs and flowers that provide limited benefits to native pollinators and protection against flooding. In response to this, the USFWS partnered with McConnell Air Force Base (AFB) to plant native species and construct a nature-based stormwater management system.
The Southeast Arizona Collaborative Grassland Workgroup was created in 2010 to develop a southeastern Arizona Regional Pronghorn Strategy to increase pronghorn population numbers, distribution, and connectedness. The project aimed to improve habitat connectivity and access to available water sources through strategic fence modifications, and improve habitat quality through grassland restoration and addition of water sources.
In response to the lack of flooding that regularly waters the wetland, The Nature Conservancy (TNC), Utah Division of Wildlife Resources (UDWR), private engineering firms, and additional state and federal agencies began collaborating in 2015 to improve wetland conditions for Razorback Suckers and other wetland-dependent wildlife in the Scott Matheson Wetland Preserve, Utah.
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.
Jackson Park, along the Lake Michigan shoreline in Chicago, Illinois is a historic park and valuable green space for the city. The park was overrun with invasive species and degraded from poor geomorphology. This project restored 16 hectares of habitat while preserving and rehabilitating the cultural history of Jackson Park.
Since 2009, the Grand Teton National Park (GTNP) has been working to restore 4,500 acres of converted hay fields to their natural sagebrush conditions—conducting controlled experiments, initial restoration, and an adaptive management approach to achieve long-term, high quality ecological restoration goals.
The Kenilworth Marsh tidal wetland restoration project, led by the National Park Service, aimed to restore areas in Washington, D.C. that were degraded from altered hydrology and contamination. The project team placed 130,000 cubic yards of dredged material to restore hydraulic function of the tidal marshes, installed over 350,000 native plants, and removed invasive purple loosestrife and phragmites.
