Georgia Bat Survey Guidance

When do I need to conduct a survey?

Survey requirements vary depending on the type of project and required permits. Projects within the potential range of the Indiana bat (Myotis sodalis), gray bat (Myotis grisescens) or the northern long-eared bat (Myotis septentrionalis) may require a survey. Potential range maps can be found below.

For questions regarding surveys for specific projects, please contact Carrie Straight at the USFWS Georgia Ecological Services Office at 706-613-9493 or

Potential Ranges

Who can conduct surveys in Georgia?

Any surveys where bats will be captured must be conducted by individuals with current state and federal scientific collecting/endangered species permits. Any bat survey report should contain scanned copies of a valid state and federal permits, if required, as part of the appendices.

How can I get a permit?

Permits will not be issued to individuals who cannot demonstrate extensive experience capturing, handling and identifying eastern bat species. Proper federal and state permits must be obtained before any bat surveys can be completed in Georgia. State permits will not be issued without first obtaining a federal permit. State permits will be issued before federal permits are secured for Georgia only if the permit requester has current federal permits for other states and has applied for a federal permit in Georgia.

What survey guidelines should I follow?

The current Range-wide Indiana Bat Summer Survey Guidance and additional informative documents for Indiana bats and northern long-eared bats can be found here:

Surveyors in Georgia should follow the most current Range-wide Indiana Bat Summer Survey Guidance for the Midwest and Ozark: Central Recovery Units with the following exceptions:

Survey Methods

Georgia Survey Modification #1: Because of the current lack of capture data for bats in Georgia, the acoustic only option will not be accepted in Georgia, unless prior approval is received by the USFWS Georgia Ecological Services Office. This option may be accepted in the future but currently acoustic surveys should be done in concert with mist-netting surveys. If a site cannot be effectively netted for bats, acoustic units can help to provide information on the presence/absence of threatened or endangered bat species-in some specific situations (e.g., an open site, wind farm location, lack of suitable netting corridor, etc.), an acoustic unit may substitute for mist netting, upon prior approval of the USFWS Georgia Ecological Services Office. A bat survey plan should be submitted prior to the commencement of surveys. Feel free to contact Carrie Straight at the USFWS Georgia Ecological Services Office (706-613-9493 or with any questions regarding deviation from the survey protocol or for assistance with determining survey efforts for any project.

Acoustic surveys should be conducted at sites independent from the netting sites along an appropriate travel corridor. Three detector nights for non-linear projects and two detector nights for linear projects should be completed for each mist net survey site, as defined in the most current Range-wide Indiana Bat Summer Survey Guidance at

Follow the Range-wide Indiana Bat Summer Survey Guidance for both linear and non-linear projects. There is an option for modification of project-specific survey plans, based on available habitat within the survey area. Please contact the USFWS Georgia Field Office to discuss any planned modifications. A bat survey plan should be submitted to the USFWS Georgia Field Office prior to bat surveys. The USFWS Georgia Field Office has 14 days to respond to any suggested modifications to the survey plan. After 14 days of no response, investigators may proceed with their surveys. Emailing the survey plan, with "Bat Survey Plan for Review" in the subject line is the preferred method of receiving survey plans.

At least one federally permitted biologist must be present at any survey locale to correctly identify bats, supervise technicians, and/or to affix transmitters. A survey locale should not exceed a maximum of eight net sets within reasonable walking distance.

Tracking Target Species

Any Indiana bat (Myotis sodalis) or northern long-eared bat (Myotis septentrionalis), i.e., males, females, and juveniles, captured should be fitted with a radio transmitter, if it meets the minimum weight requirements in the most current Range-wide Indiana Bat Summer Survey Guidance. Please notify via phone or email the USFWS Georgia Field Office and Katrina Morris at GA DNR once transmitters are affixed and telemetry studies begin for Myotis sodalis or septentrionalis.

Bats should be tracked for at least 7 days or 40 receiver hours, whichever comes first. Early cessation of telemetry requires a phone call to USFWS Georgia Field Office and Katrina Morris at GA DNR as a courtesy, so that we may choose to continue telemetry.

Voluntary Tracking Efforts

Although little brown bats (Myotis lucifugus) are not federally protected, capture rates in Georgia are very low. If able, we recommend tracking any Myotis lucifugus that are captured. They should be fitted with a radio-transmitter for every site they are captured. Any bat fitted with a transmitter must meet the minimum weight requirements in the 2016 Range-wide Indiana Bat Summer Survey Guidelines.

Bats should be tracked for at least 7 days or 40 receiver hours, whichever comes first. Please contact Katrina Morris at GA DNR if these bats are captured so that we can assist with telemetry efforts.

Netting efforts should continue even if a target species is captured. Because of the lack of survey data in Georgia, all sites should be surveyed for the required survey period even if target species are captured.

Transmitter frequency ranges should be included in the submitted survey plan.


All Myotis bats captured in Georgia should be banded with the exception of small-footed bats (Myotis leibii). All Myotis bats should be banded with a 2.9mm band. All tri-colored bats (Perimyotis subflavus) should be banded with a 2.4 mm band. Only GA bands provided by GA DNR should be used for banding. Bands should be applied (and removed) using one of the commercially available bat banding tools. Porzana 2.9 mm and 2.4 mm bands are available for use by permitted surveyors in Georgia. Please contact Katrina Morris to obtain bands.

Species from Feces

GA DNR requests that feces be collected for genetic confirmation of rare and difficult to identify bat species. We request guano collection from any Myotis sodalis, Myotis lucifugus, Myotis austroriparius (in the Myotis septentrionalis range), or any questionable M. septentrionalis or M. septentrionalis found in the coastal plain of Georgia. You can obtain kits by contacting Northern Arizona University or request a small number of kits free of charge by contacting Katrina Morris.


All surveyors are required to follow current USFWS white-nose syndrome decontamination protocols and advisories. Current guidelines.

Submitting specimens to the GA Museum of Natural History (GMNH)

In the event that any deceased bats are encountered during field surveys, intact specimens should be provided to the GMNH. Please contact Nikki Castleberry, Assistant Curator of Vertebrate Collections for submission guidelines.

Injured bats that are likely to recover may be transferred to a licensed rehabilitation facility. In North Georgia, AWARE ( is a good resource for rehabilitation.

How do I submit survey plans?

Survey plans must be submitted to the USFWS Field Office as a pdf document. If you do not get a response within 14 days of submission, you may proceed with the survey as planned. If you are not already coordinating with a biologist at the USFWS Georgia Field Office, email plans to Carrie Straight at for routing.

How do I submit my survey data?

Summer survey mist netting data should be submitted after completion of each field season. Please use this template for submission of capture data.

Instructions for data entry are provided on an additional sheet in the excel document. Please submit completed survey data to Katrina Morris.

Any suspected calls of federally listed species can be sent to Carrie Straight via email or on DVD with the appropriate location information.
