File Wood placement in river restoration: fact, fiction, and future direction
Despite decades of research on wood in rivers, the addition of wood as a river restoration technique remains controversial. We reviewed the literature on natural and placed wood to shed light on areas of continued debate. Research on river ecology demonstrates that large woody debris has always been a natural part of most rivers systems. Although a few studies have reported high structural failure rates (>50%) of placed instream wood structures, most studies have shown relatively low failure rates (<20%) and that placed wood remains stable for several years, though long-term evaluations of placed wood are rare. The vast majority of studies on wood placement have reported improvements in physical habitat (e.g., increased pool frequency, cover, habitat diversity). Studies that have not reported improvements in physical habitat often found that watershed processes (e.g., sediment, hydrology, water quality) had not been addressed. Finally, most evaluations of fish response to wood placement have shown positive responses for salmonids, though few studies have looked at long-term watershed-scale responses or studied a wide range of species.

File D source code Mill Creek “Chop and Drop”, WV_FY14 Project
Mostly dead and/or down hemlock trees were utilized to create large woody material inspired habitat structures to increase pool habit, increase thalweg meander length, decrease bankfull width, and introduce overhead fish cover. Cross-vanes, j-hooks, wing-deflectors, toe wood, digger logs, and engineered log jams were constructed. The strategic part of this chop and drop effort was to place and anchor logs to minimize movement in bankfull or high events.

File Assessing the Efficacy of Remediating Episodic Low pH (and High Aluminum) Concentrations in Headwater Brook Trout Streams with Clam Shell Additions_FY09 Project
This project demonstrated that clam shells could be utilized to increase pH and decrease detrimental inorganic aluminum concentrations. In Dead Stream, water chemistry has improved by approximately 1.0 pH unit, and total fish densities increased two-fold. In Canaan Brook water chemistry has improved by 1.0 pH unit and First Lake Stream improved by 0.7 pH unit, while fish densities have increased 2- and 6- times, respectively. Macroinvertebrate communities have improved somewhat, especially among mayflies and stoneflies, while amphipods and snails have appeared for the first time. However, even at treated sites, macroinvertebrate communities continue to have low diversity and may not achieve Class A water quality. Overall, by adding buffering capacity, there has been a boost to the bottom of the food chain which has contributed to improved fish abundance and diversity. In the fourth year, biological communities are still adapting to the new conditions.

Project Habitat Restoration to Benefit Rare Species and Natural Communities in the Altamaha River Watershed
Cool water springs feeding major coastal rivers in Georgia provide critical thermal refuges during summer for diadromous fishes such as striped bass. However, the connectivity of many of these springs to the main rivers has been diminished by drought, sedimentation, accumulation of debris, and beaver dams. The goal of this project was to improve the connectivity of Troup Springs to the Oconee River and enhance spring flows.

Project Restoration of Critical Habitat for LIsted Mussels and Fish, Big South Fork NRRA, TN/KY
The Big South Fork National River and Recreation Area is a focus for major conservation efforts due to the outstanding aquatic features found in the Big South Fork of the Cumberland River. The park is also a favorite location for equestrian riders, cyclists, and hikers. Managing a park for such multiple uses, while conserving biodiversity, is wrought with challenges.

Project chemical/x-pdb Gravel Augmentation at Spawning Habitats in the Oconee and Ogeechee Rivers of Georgia
The robust redhorse (Moxostoma robustum), a species that had been lost to science for about 150 years, was discovered on the Oconee River in 1991. Wild populations subsequently found in the Savannah River (Georgia/South Carolina) and Pee Dee River (North Carolina) have been augmented by stocking in other areas of Georgia and South Carolina. The species is very particular about the water quality and depth as well as the gravel quality of its spawning sites. To encourage propagation of this native species, the Robust Redhorse Conservation Committee coordinates activities in several southeastern states. The gravel augmentation is expected to benefit invertebrates, including mussels, as well as anadromous species such as striped bass, American shad, and Atlantic sturgeon.

Project Jockey's Ridge State Park Community-based Living Shoreline Restoration Phase I and II
Jockey’s Ridge State Park is the location of the largest sand dune system on the east coast. It is part of the Roanoke River Watershed, which flows from Virginia through North Carolina to the sea. Its estuarine shoreline had never been stabilized prior to making the area into a state park. However, the estuarine shoreline had been damaged by vehicle and foot traffic, and acres of salt marsh had disappeared.
