Genetic and demographic modeling of two endangered mussel species, Epioblasma brevidens and E. capsaeformis, in the Clinch River, U.S.A., was conducted to determine quantitative criteria to evaluate performance of extant and reintroduced populations. Reintroduction modelling indicated that the initial population size created during a 5 year build-up phase greatly affected final population size at 25 years, being similar to the population size at the end of the build-up phase, especially when population growth rate was low. Excluding age 0 individuals, age 1 juveniles or recruits on average comprised approximately 11% and 15% of a stable population of each species, respectively. Age-class distribution of a stable or growing population was characterized by multiple cohorts, including juvenile recruits, sub-adults, and adults. Because of current barriers to dispersal and the low dispersal capability of some mussel species, reintroductions will play a prominent role in restoring populations in the United States.

Mill Creek Watershed has been negatively affected by urbanization,resulting in increased sedimentation,reduced habitat quality, ultimately resulting in the Nashville crayfish being federally listed. This project will restore an unnamed tributary of Mill Creek by removing a barrier and restoring connectivity of the tributary.

Native Brook Trout
Drought and stressed habitat conditions exacerbated natural competition for food and space between brook trout and rainbow trout in several creeks in the Cherokee National Forest. Both species, popular with anglers, were declining due to drought in recent years. By improving or restoring habitats, and removing rainbow trout from certain areas, both species can more easily thrive in the forest.

Native Brook Trout
Brook trout, the only salmonid native to the southeast, have lost about 75% of their historic range due to past logging activities and introduction of non-native trout. In 1993, the National Park Service identified 10 streams that can support native southern Appalachian brook trout (Salvelinus fontinalis). The long term goal is to restore historic range of habitat for this native species.

Excessive sediment from channelized tributaries of the Hatchie River (TN) are degrading downstream aquatic habitat. Pleasant Run Creek is a channelized tributary to the Hatchie River, exhibiting significant soil erosion and channel incision problems. This project seeks to implement channel stabilization measures on private lands that will improve riparian habitat on Pleasant Run Creek and reduce sediment loading to the Hatchie River.

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.

The Allen family’s dairy, Dairy Made Farm in western Marshall County, is a top priority site for conservation work on the upper Duck River. The farm has been an Allen family operation for generations and is now operated by Cannon and John Daniel Allen. It is up-stream and adjacent to a reach of the Duck from Lillards Mill to Venable Spring, one of the most biologically diverse reaches of the entire river system. The opportunity to work with the landowners on this important site arose late in 2007 and it promises to be an exciting and beneficial project for all involved.
