3.1.3.2 Acoustic Monitoring of Bats on the ORR 2015 (Draft)
Acoustic bat surveys were conducted at eight major ORR areas and adjacent areas during 2015: (1) Haw Ridge Park, (2) Bethel Valley (ORNL), (3) ETTP west ponds, (4) Upper East Fork Poplar Creek floodplain (UEFPC), (5) White Wing Scrapyard Area (WWSY), (6) ETTP proposed airport site, (7) Parcel ED-5 (Horizon Center), and (8) Freels Bend Wildlife Management Area. For 209 nights during 2015 (multiple detectors deployed/night), approximately 226,000 files of bat acoustic data were recorded at 48 field stations (Table 3.1.3.2.1) and were processed with specialized, automated bat identification software (Kaleidoscope PRO) yielding 12,567 bat identifications. An additional 2,249 bat calls were detected but not identified to species due to poor call quality, inclement weather conditions, or field clutter. Fourteen species were detected on the ORR including: Townsends big-eared bat, big brown bat, eastern red bat, hoary bat, silver-haired bat, southeastern bat, eastern small-footed bat, little brown bat, northern long-eared bat (federally-listed threatened), Indiana bat (federally-listed endangered), evening bat, tri-colored bat (eastern pipistrelle), and the Mexican free-tailed bat (Table 3.1.3.2.2, Figure 3.1.3.2.1). Of these species, the hoary bat (18%), silver-haired bat (16%), eastern red bat (11%), and big brown bat (11%) were the dominant combined species detected at all sites. Federally-listed species detected included the gray bat (7%), Indiana bat (1%), and northern Long-eared bat (>1%).
TDEC documented all three federally-listed bat species with acoustic surveys on the ETTP proposed airport site in bat roost trees such as white oaks and dead snags. The information was shared with the TWRA, DOE, and the USFWS.
TDEC also documented all three federally-listed bat species with acoustic surveys on the Parcel ED-5 (Horizon Center), in bat roost trees such as white oaks, shagbark hickory, and dead snags. The information was shared with the TWRA, DOE, the City of Oak Ridge, and the USFWS.

CONCLUSIONS TDEC monitored 48 sites on the ORR with acoustic detectors through the course of 37 dusk to dawn surveys. Over 226,000 bat call files were collected over 209 survey nights. Approximately 12,567 bats were identified to species; 2,249 were not identified. Threatened and endangered bats were detected at 25 of 48 sites surveyed. Information will be used to facilitate the protection of these species.
