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.

The Portland Water District conducted a green-gray analysis to compare natural versus gray infrastructure for an EPA-granted filtration system to improve Sebago Lake's water quality. They ultimately chose to invest in forest-based natural infrastructure, including restoring riparian buffers and reforesting riparian zones.
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.
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 2012, the Colorado State Forest Service (CSFS) led the Lower North Fork Prescribed Fire Project on a 50-acre unit of the Denver Water property. However, a rapidly escalating wind event carried ground-level embers across the established prescribed fire control line, resulting in three spot fires that eventually led to an escape and conversion to a wildfire.
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.
The state of Florida is working to control invasive Burmese pythons to reduce their impact on native species in the Everglades National Park. This project aimed to identify effective techniques for detecting and removing Burmese pythons, controlling their spread, and educating local partners about their impacts.
The West Lake estuary and watershed is an urban/suburban estuary ecosystem with one of the largest ports in the USA (Port Everglades). Dredging and filling in support of this port have modified both the shallow edge and bottom of the estuary. This project successful establishment of 500 hectares of mangroves at West Lake in Broward County, Florida.
This project aims to clear dead trees and debris deposited by Hurricane Andrew in 1992 from mangrove tidal passageways in Matheson Hammock Park on Biscayne Bay. In a five-year effort to prevent further damage to this sensitive habitat, the debris are removed by volunteers using canoes and manual labor instead of large machinery.
Forests in Arizona are increasingly affected by persistent drought conditions due to global warming. The Four Forest Restoration Initiative (4FRI) researched the effects of climate variability and accelerated forest thinning on watershed-scale runoff, aiming to improve water flows and reduce forest mortality. The focus was on ponderosa pine forests.
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.
The confluence of Mud Creek and the French Broad River in Henderson County, North Carolina was degraded by agricultural development and urban runoff. The Mud Creek confluence project addressed these issues by restoring a montane alluvial floodplain forest, a rare natural community in North Carolina made up of specific vegetation communities and habitats.
To reduce the damage of future wildfires, the Paradise Recreation and Park District (PRPD) established multi-benefit greenspaces, or natural areas for recreational and aesthetic purposes (e.g. parks), within Paradise’s eastern and southern borders. These greenspaces will help increase community wellbeing and prevent trauma associated with wildfire by providing a multitude of recreational activities, conservation benefits, and local economic opportunity.
The New England Cottontail Project is a restoration effort with the objective to restore the New England Cottontail (Sylvilagus transitionalis) to their native habitats through the creation of young forest and captive breeding programs. Led by USFWS, young forests were created through tree/ shrub cutting, heavy-duty mowing/mulching, field mowing, forest harvesting, controlling invasive plants, and prescribed burning.
The National Park Service led an oak savanna restoration project along a 5-acre stretch of the Mississippi River Gorge in a Minneapolis neighborhood. The project sought to eliminate the threat of exotic species, reintroduce the appropriate gorge plant community, and address erosion concerns with the collaborative effort of national and local agencies, and the advocacy of the local community.
The Ohkay Owingeh riparian restoration project is a series of coordinated projects reaching back to the 1990s that now encompasses over 700 acres of restored ecological mosaic including wetlands, cottonwood gallery forest, grassland, shrub cover, open water, and dense emergent willow thicket that is ideal for bird habitat, particularly Southwestern Willow Flycatcher.
The Regional Transportation Authority partnered with the Arizona DOT to construct two wildlife crossing structures (one overpass and one underpass) with adjacent wildlife-funnel fencing on Oracle Road to help wildlife move between protected habitat areas. The two wildlife crossing structures were constructed at the best available location to accommodate both large mammals and small animals.
This project explored the potential of using Wildfire Risk Reduction Buffers (WRRBs) between the urban area and the wildlands for fire risk reduction. The team selected Paradise, CA as its prioritization site due to its fire risk, opportunity, and recreation value. They created five buffers totaling 34,553 acres and conduct habitat-sensitive fuel reduction and open space management.
Two major fires and subsequent flooding events wreaked havoc on a critical watershed and reservoir that supplies Denver with water. Water utilities partnered with the U.S. Forest Service and corporate sponsors to manage the watershed and improve forest health.
