Welcome to the Tennessee Bat Working Group

The Tennessee Bat Working Group (TNBWG) was formed in the summer of 2004 in recognition of the need for cooperation among various groups and individuals to help coordinate the conservation of bat species in Tennessee. evening bat

The scope of the TNBWG is the study and exchange of information relative to the conservation, biology, ecology, and management of bats and their habitats on all state, federal, and private lands within the state of Tennessee. The goal of the TNBWG is to conserve bats and their habitats in the southeastern United States through collaborative research, education, and management with a focus on bat research, conservation, education, and management within the state of Tennessee. Find more TNBWG information and details about upcoming meetings on the "About" page of this site.

Upcoming Events

TNBWG Citizen Science Project

The TNBWG is coordinating a state-wide summer maternity roost monitoring program. This program uses emergence counts and multi-state coordination to investigate emerging wildlife health threats. The goals of the survey are to: Gather base line information on summer colonies; evaluate the impact of WNS on summer colonies; and correlate long term trends of Tennessee bats.

If you are interested in participating in this program, please read through the Summer Bat Roost Registration Forms and Volunteer Survey Guidance.

"Mini" Bat Blitz

The Cherokee National Forest will be hosting a "mini" bat blitz July 22nd and 23rd on the Ocoee Ranger District in Benton, TN. Participants will be camping at the Thunder Rock Campground.

Recent Events

The working group held a bat blitz at Edwin Warner Park in Nashville on May 16th. Unfortunately, low temperatures cut the night short with only 1 capture of a Tri-colored bat and several acoustic recordings of Red bats. Despite the low captures, It was a really good experience and we appreciate the cooperation of Nashville Metro Parks staff and all that attended.

The 2013 TNBWG meeting was held at Fall Creek Falls State Park on November 21st with over 70 bat researchers and bat enthusiasts in attendance.

White Nose Syndrome

Described by some biologists as the most precipitous wildlife decline in the past century in North America, White Nose Syndrome (WNS) has killed more than 1 million bats since it was discovered in 2006.

WNS gets is name from the white fungal growth typically found on the face and wing membranes of infected bats.

More details on White Nose Syndrome in Tennessee can be found at the TNBWG WNS page. National information can be found on the U.S. Fish and Wildlife Service WNS website and Fact Sheet.
