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.

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.

If you have upcoming bat related events here in Tennessee that you would like to share with the TNBWG here on our website, please contact us!

Working group members present a bat program for Vanderbilt's School of Science and Math.

A bat presentation was given at the Williamson County Library by Sara Samoray and can be viewed Here on YouTube.

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 TNBWG helped deliver some bat facts to visitors at the Adventure Science Center in Nashville during their "Spooky Science" program. Thanks to Stephanie for inviting us to participate.

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.
