Interior Low Plateau subregion climate change vulnerability species assessments
-
These results are a compilation of climate change vulnerability assessments in the western portion of the LCC, covering the area from Western Kentucky, northeastern Alabama and western Tennessee west to southern Indiana and southeastern Illinois. Results included are from Bruno et al. (Cumberland Piedmont Network of the National Park Service; and Walk et al. 2011 (illinois). It also includes the results from species assessed as part of the current study (Sneddon et al. 2015).

Nashville crayfish Habitat Restoration on the Nashville Zoo Property
-
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.

Population Performance Criteria to Evaluate Reintroduction and Recovery of Two Endangered Mussel Species, Epioblasma brevidens and Epioblasma capsaeformis
-
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.

Reintroduction of Native Brook Trout into Indian Flats Prong, Great Smoky Mountains National Park
-
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.

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.

Stream Restoration & Protection on Agricultural Lands in the Upper Duck River Watershed
-
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.

Three new darter species of the Etheostoma percnurum species complex (Percidae, subgenus Catonotus) from the Tennessee and Cumberland River Drainages
-
The federally endangered Duskytail Darter, Etheostoma percnurum Jenkins, is known from only six highly disjunct populations in the Tennessee and Cumberland river drainages of Kentucky, Tennessee, and Virginia. Only four are extant. Variation in morphology including meristics, morphometrics, and pigmentation was examined among the four extant populations and limited specimens from the two extirpated populations (Abrams Creek and South Fork Holston River). Analyses of these data found each of the extant populations is morphologically diagnosable. The few specimens avail- able from Abrams Creek and South Fork Holston River prevented thorough assessment of variation, and these were grouped with their closest geographic counterparts, Citico Creek, and Little River, respectively. Three new morphologi- cally diagnosable species are described: E. sitikuense, the Citico Darter, from Citico Creek, Abrams Creek, and Tellico River (Tennessee River system); E. marmorpinnum, the Marbled Darter, from the Little River and South Fork Holston River (Tennessee River system); and E. lemniscatum, the Tuxedo Darter, from the Big South Fork (Cumberland River system). Each species warrants federal protection as an endangered species.
