The Nature Conservancy led the project to restore 7,100 acres of farmland to functional flood plain and return its ability to sustain native plant and wildlife species. In 2007, 180,000 trees, 8,000 pounds of seed, and 90,000 upland shrubs and trees have been planted in 1,400 acres of Emiquon.

This project aimed to restore oyster populations in Pensacola Bay, St. Andrews Bay, and Apalachicola Bay in Florida. This project placed 49,000 cubic yards of cultch material over 210 acres of previously constructed oyster bars. This project hoped to maximize oyster larvae settling and oyster colonization at each restoration site. 

Led by the Texas Parks and Wildlife Department (TPWD), this project aimed to apply the integrated pest management (IPM) approach to control the invasive giant salvinia (Salvinia molesta) in Lake Raven, a 203-acre reservoir located in the Huntsville State Park, Texas.

Goldbug Island, off the coast of Charleston, SC, was experiencing erosion and salt marsh loss. To prevent further loss, the Nature Conservancy constructed a 67-meter-long oyster castle reef. This reef prevents erosion, mitigates wave energy, enhances biodiversity, and with increased oyster settlement, will improve water quality. 

Grassy Point is a 100-acre wetland where the St. Louis River meets Lake Superior. It used to be home to several sawmills which unfortunately left debris behind to clog up the waters. This project eventually removed 11,000 cubic yards of wood debris from the site and reformed several channels during 1994-1996.

Funded by the USEPA’s Great Lakes Restoration Initiative, a wetland system is constructed to reduce phosphorous loading in a forested cropland. Phosphorus is removed through natural processes such as particulate nutrient sedimentation, sorption to soil particles, and uptake by wetland plants. The project achieved a 50% - 80% phosphorus reduction and co-benefits like wildlife and fish proliferation.

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.

Tuscon, Arizona faced stormwater management problems, with increased flooding and runoff, and degraded water quality. To address these issues and improve the urban tree canopy and recycle rainwater for irrigation, the city developed the Green Streets Active Practice Guidelines. This program requires integrating green infrastructure into all publicly funded roadway projects. 

The Nature Conservancy restored a 54-acre oyster reef in Matagorda Bay, Texas. This project successfully restored large, thriving oyster reefs that have enhanced biodiversity in the bay. This increase in biodiversity has improved recreational fishing opportunities and fishing-related tourism in the area. The increase in fishing at Half Moon Bay reef adds around $691,000 to Texas’ gross domestic product annually.  

The Harbor Brook CSO 018 Constructed Wetlands Pilot Project serves the dual purposes of treating overflows from CSO 018, currently discharged into Harbor Brook, while also acting as a demonstration project to test the effectiveness of three types of constructed wetland treatment systems (floating wetland island, vertical down flow, and surface water treatment wetlands).

The Herring River Restoration Project in Massachusetts will replace the restrictive dike at the mouth of the river with a bridge that will allow tidal water to flow freely between the river and Wellfleet Harbor. This will restore the biodiverse, productive, estuary that existed pre-dike construction.  

The suburban city of Mount Rainer, Maryland aimed to restore the water quality Anacostia River, which was polluted by polluted stormwater runoff from urban and agricultural lands. The city developed Urban Green Infrastructure Plan to encourage community members to install nature-based stormwater control practices.

A collaborative effort among irrigators, conservation interests, regulatory agencies, local entities, and nonprofit organizations is working to restore the declining Colorado River Cutthroat Trout population in Abrams Creek, Colorado that had been impacted by water diversion. The team piped the ditch to improve the irrigation efficiency and conserved 40% of the diverted water.

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.

The Kissimmee River Restoration project aimed to restore over 40 square miles of river/floodplain ecosystem in Central and South Florida after two major hurricanes in the late 1940s caused mass flooding and property damage throughout the upper basin. The project encompassed two primary components: backfilling the C-38 canal and changing water level management practices.

This project aimed to restore the Lavaca Bay from being contaminated by discharged mercury from a chlorine-alkali processing unit at its Point Comfort. A staged approach to restoration was adopted with the first stage focused on recreational fishing service losses. The second stage focused on natural resource injuries and service losses of an ecological nature.

Cincinnati is one of the nation’s top five combined sewer overflow (CSO) dischargers, causing severely polluted waterways and building damage. The Lick Run Watershed hosts the Cincinnati-area's largest combined sewer and was a priority for improved stormwater management. The Lick Run Watershed Strategic Integration Plan aims to eliminate 400 million gallons of combined sewer overflow annually.  

The Three Forks Ranch in Routt County, Colorado was purchased by David Pratt in 1999. Dave Rosgen of Wildland Hydrology was later hired to improve the hydrology and habitat conditions of a 10.5-mile stretch of the Little Snake River flowing across the property.

The Lower Boulder Creek Floodplain was degraded by gravel mining. This creek’s natural stream geomorphology was restored by adding riffles, pools, and large woody debris. The creek was reconnected to its historic floodplain, creating vegetated seasonal wetlands, improving water quality, and reducing flash flood risk. 

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.
