This SSP project produced a Final Report and two publications. Carey, C.S., J.W. Jones, R.S. Butler, E.M. Hallerman. 2015. Restoring the endangered oyster mussel (Epioblasma capsaeformis) to the upper Clinch River, Virginia: an evaluation of population restoration techniques. Restoration Ecology. DOI: 10.1111/rec.12195. From 2005 to 2011, the federally endangered freshwater mussel Epioblasma capsaeformis (oyster mussel) was reintroduced at three sites in the upper Clinch River, Virginia, using four release techniques. These release techniques were (1) translocation of adults (site 1, n=1418), (2) release of laboratory-propagated sub-adults (site 1, n=2851), (3) release of 8-week-old laboratory-propagated juveniles...

One of the most diverse freshwater mussel assemblages in the world once occurred in the Cumberland and Tennessee Rivers. Several of these species are now extinct; others linger on as relic, nonreproducing populations, and populations of the remaining species have also declined. Although many factors contributed to the decline of mussels, habitat loss from impoundments and poor water quality in tailwaters have been major causes. Recently, the Tennessee Valley Authority (TVA) initiated a major program to improve water quality in the tailwaters by maintaining minimum flows and by oxygenating discharged water. This program has resulted in significant improvements in water quality. These improvements have resulted in...
With the onset and advance of whitenose syndrome (WNS) across USFWS Regions 2-6 managers realized that then current Indiana bat presence and absence survey guidelines were likely insufficient due to population declines. The objectives of this study are: 1. Continue to test automated bat identification software following USFWS and USGS jointlydeveloped protocols and standards as submitted to USFWS over the study period and report findings 2. Establish and operate zero-crossing, frequency division survey sites in representative upland, riparian and field-edge habitat in areas with recent past (since advent of WNS) or currently known Indiana bat maternity colonies in KY, TN, VA, IN and NY. 3. Establish and operate...
