To restore a degraded but historically, culturally, and ecologically important watershed on O‘ahu’s Eastern Coast, The Nature Conservancy collaborated with local partners aiming to restore 405 acres of wetlands and promote traditional Hawaiian agricultural practices. The project involves removing invasive red mangroves, replanting native plants, and restoring natural stream flow.

Since 2018, the Central Kootenay Invasive Species Society (CKISS), along with government, tribal nations, stakeholders, and international partners, has been removing invasive American bullfrogs from Idaho to BC along the Kootenay (Kootenai) River to protect Northern leopard frog habitats. Due to limited knowledge about bullfrog distribution in the Kootenay Valley, a coordinated landscape-scale approach was implemented.

Non-native Boer and Lehmann lovegrasses threatened the native grasslands at the Appleton-Whittell Research Ranch (AWRR). AWRR staff began experimenting with treatments of lovegrass in the late-1990s to discover effective methods to protect and rehabilitate native grasslands. Chemical treatment (glyphosate + colorant + surfactant) was the only method that was effective.

Country Acres Road- Richmond, Rhode Island, was once home to mixed temperate forest with seasonal freshwater wetlands before degraded by mining of sand and gravel and dominated by invasive plants. The goal was to restore the non-forested formerly mined acreage to native grass and wildflower meadow.

Managers at the Marine Corps Air Station Yuma (MCASY) used a web-based weather-monitoring network and a cloud-based mapping app to help detect, map, monitor, and treat invasive Sahara mustard (Brassica tournefortii) and buffelgrass (Pennisetum ciliare) at the Barry M. Goldwater Range-West (BMGR-W) of the Sonoran Desert in southwestern Arizona.

In the 1980s, the City of Tuscon implemented a “storage and recovery” (S&R) strategy to reduce its unsustainable reliance on groundwater. They treated groundwater, stored it in the aquifer, and reuse the treated water for non-portable water needs instead of pumping fresh groundwater. The Sweetwater Recharge Facilities features 40 acres of recharge basins and 22 acres of constructed wetlands.

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.

Crystal Springs Creek runs directly through the city of Portland, Oregon. This creek was disconnected from its floodplain from urban and agricultural development and channelization, leaving the water too warm for important salmonid species. This project restored 730 meters of the creek, improved salmonid habitat, and created a thriving urban park.   

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.
