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.

Encompassing 100 acres of tallgrass prairie converted into agricultural land and 60 acres of woodland along a creek, Homestead National Historical Park underwent restoration by the National Park Service in 1939 to address severe erosion and improve water quality and soil productivity to support native plants and wildlife.

State/Territory:

Teaneck Creek Park is a low-lying area in a highly urbanized neighborhood of North New Jersey. During storm and rain events, this area experienced flooding, erosion, and produced untreated runoff that degraded Teaneck Creek. This project restored 8 hectares of wetland habitat to mitigate these negative outcomes.

In 2017, the City of St. Louis Park, Minnesota implemented the Rainwater Rewards Program with the goal of increasing awareness and importance of managing stormwater and green infrastructure throughout the city. The program seeks to increase green infrastructure by providing residents with financial and technical assistance to install projects that reduce stormwater runoff on residential properties.

The Elizabeth River Project (ERP) is a nonprofit based in Norfolk, VA is working with a wide range of partners to restore the Elizabeth River through nature-based solutions projects. The river has suffered from habitat loss and pollution. ERP implements projects to improve water and habitat quality.

The Wild Mile restored a mile-long stretch of the Chicago River on the urbanized North Branch Canal in Chicago, Illinois, USA. The Wild Mile is floating ecopark - an innovative solution to enhance ecology along concrete-channelized river in a heavily industrialized area.

State/Territory:

Tulalip Tribe and other tribes in the Snohomish basin are concerned by the decline in salmon population in the region. Salmon loss is considered an economic, cultural, and spiritual threat to the tribal members’ lifeblood and identities. Local groups worked with farmers to control agricultural runoff that was found to be the major cause of salmon mortality.

In an effort to restore eleven species of sea-run fish while resuming energy production levels, state and federal agencies, businesses and non-profits bonded together to restore the Penobscot River watershed. Two dam removals and the construction of one fish by-pass, and one modernized fish ladder resulted in over 2,000 km of connected migratory fish passage.

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.

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:

In the last decade, landowners and conservation partners have increased research and restoration efforts along the Upper Bear River to rebuild irrigation diversions for water-rights holders and improve fish passage conditions and habitat. Push-up dams (river substrate berms) used as irrigation diversions have resulted in sediment accumulation, lack of riparian plant cover, and loss of fish due to channelization.

State/Territory:

The USFWS is working with the Arizona Department of Game and Fish, the White Mountain Apache Tribe (WMAT), and the USFS to recover Apache trout populations through a combination of stream restoration, captive fish production, and stocking in the White Mountains. Invasive trout species were removed through either chemical treatment (Rotenone) or mechanical removal.

State/Territory:

The Yakima River Basin in Washington State supports municipalities, tribal communities, environmental uses and agricultural uses. Droughts have historically impacted the basin's water quality and availability, and their frequency is projected to increase under climate change conditions. A working group was formed to develop a climate change water resource management plan.
