With a growing push to remove low-head dams due to safety concerns and the potential for ecosystem improvement, Corydon, Indiana was approached by The Nature Conservancy to remove two dams owned by the Town. The dams blocked potential habitat for the endangered hellbender salamander.

County of Barnstable, Massachusetts encourages municipalities to take actions that lower flood risks, which can reduce flood insurance premiums by earning credits through the Community Rating System (CRS). In one project, 26 mosquito-control workers cleaned debris out of the 1,500 miles of ditches, pipers, and other conduits that channeled stormwater away from buildings and roads.

The Mohave tui chub (Siphateles bicolor mohavensis = Gila bicolor mohavensis) is a federally endangered species that was native to the Mojave River, however now only exists in natural and man-made refuges. This project aims to establish and maintain refuges for the fish to promote recovery. 

Cuenca los Ojos (CLO) is a non-profit that preserves land and restores watersheds in the Sky Island ecoregion of the U.S. and Mexico. Sky Island contains high biodiversity, and CLO’s preserved and restored lands act as wildlife corridors and work to improve watershed health.  

Sandstone glades of the Southern Cumberland Plateau are rare and unique plant communities exhibiting some of the richest endemic floras in the eastern United States. As a part of larger conservation initiative to rehabilitate and reconnect glade patches with the surrounding forest ecosystem, USFS at William B. Bankhead National Forest conduct a pilot project on a 3-acre glade.

Curtis Prairie at the University of Wisconsin-Madison Arboretum is the site of the world's first ecological restoration project. Begun in 1936 by Dr. Theodore Sperry, the project has been ongoing for more than seventy years and has yielded a wealth of research data about the dynamics of tallgrass prairie ecosystems and the practices most effective in their restoration and management.

Coastal Louisiana contains around 40% of the wetlands in the continental United States and accounts for approximately 80% of the nation’s wetland loss due to sea-level rise, storm surges, and subsidence. This project restored 1,600 hectares of bald cypress (Taxodium distichum) forest at Pointe-aux-Chenes Wildlife Management Area. 

The District of Columbia Water and Sewer Authority (DC Water), in an effort to reduce combined sewer overflows (CSOs), is implementing green stormwater infrastructure projects to reduce runoff. These projects include rain barrels, grassed swales, cisterns infiltration trenches, permeable pavements, increased tree cover, and rooftop greening. 

Deer Island is a barrier island in the Mississippi Sound that protects the city of Biloxi from storm impacts, sea-level rise, and wind impacts. Storms caused a breach in the island, reducing elevation, killing vegetation and eroding beaches. The island was restored using dredged material to increase elevation and nourish beaches.  

This project is a cooperative initiative carried out by the Delaware Bay Oyster Restoration Task Force to revitalize the Eastern oyster (Crassostrea virginica) population in Delaware Bay. With congressional support and federal funding, the task force coordinated the planting of more than 280,000 bushels of ocean quahog, surf clam and Maryland oyster shells spread over 150 acres in 2005.

26,000 acres of Eastern Mojave Desert near Las Vegas, Nevada, is a specially managed area that receives Mojave Desert tortoises (Gopherus agassizii) translocations. A 2011 Revised Recovery Plan aims to increase population densities of the tortoise by increasing native plant coverage and reducing invasive plant presence. 

An engineer-ecologist team designed a living shoreline tailored to conditions on New England coastlines. After site analysis, the team used coir products (“marsh pillows”) in their living shoreline design. This winter storm-resistant approach slowed the erosion of a 30-foot bank, increased vegetation cover, and protected coastal properties. 

Non-indigenous crayfish species (NICS) cause widespread ecological damage throughout European waterways. They negatively impact native species through competition, predation, and disease transmission. The Swiss Coordination Office for Crayfish was formed in 2014 to address this issue in Swiss waterways by conducting research, informing local governments, and informing the public.  

The Dolores River Restoration Partnership (DRRP) is a public-private collaborative working to restore ecosystems and plant communities in the Dolores River corridor. Invasive plants in this region have degraded habitat for both native plants and wildlife, increased wildfire risk, and negatively impacted recreational opportunities. The project has four broad goal categories: ecological, social, management, and economic. 

In Midland, Michigan a former ash pond for a coal-fired powerplant is located within the floodplain of the Tittabawssee River. Instead of the traditional (and expensive) cap and long-term maintenance plan, Dow's corporate nature team removed the ash and restored the area to a conservation wetland.  

The U.S. Army Corps of Engineers established a 5-hectare marsh on Drake Wilson Island off of the coast of Florida in 1976. This was one of the earliest beneficial use of dredged material projects for habitat enhancement. For more than 40 years, this marsh has created recreational opportunities and reduced erosion. 

The New Orleans district of the U.S. Army Corps of Engineers is strategically placing dredged sediment from the Mississippi River federal navigation channel to restore marsh habitat, improve and ensure the integrity of the navigation channel, and promote sediment deposition in the bay. 

A dam placed in Dry Creek in Sonoma County, California degraded important fish habitat. Instead of building an expensive and unattractive bypass pipeline, the Dry Creek Ecosystem Restoration Project restored 30 hectares of stream, floodplain, and riparian habitat. This project increased in-stream habitat complexity and improved hydrologic connectivity with the floodplain.  

The 21st Avenue West Channel Embayment of the Duluth-Superior Harbor is the site of shoreline habitat restoration. Dredged materials were placed in three locations of the embayment to restore shallow aquatic habitat, with the hopes of contributing to the delisting of the St. Louis River Estuary as an Area of Concern. 

This project is testing the effectiveness of dune restoration as a tactic for combatting sea-level rise and erosion in Southern California. Sand dunes were constructed from locally dredged material and planted with native vegetation. It is projected that this project will successfully protect the shoreline from flooding with no additional sand maintenance until 2050.
