The Tennessee Amphibian Monitoring Program (TAMP) is a joint venture between the Tennessee Wildlife Resources Agency and the Middle Tennessee State University Center for Environmental Education.
There are 21 species of frogs and toads in Tennessee. With the data gathered from TAMP, we hope to better understand the distribution and relative abundance of each species.
TAMP volunteers drive routes that are have been selected by the North American Amphibian Monitoring Program (NAAMP) and are randomly placed across Tennessee. Ten listening stations are established along each route.
Listening stations are placed at least 0.5 miles apart, and are placed where wetland habitat exists. Four listening runs are made each year. Each runs begins at least 30 minutes after sunset and finishes before 1:00am. There is a minimum temperature for each listening run.
Each anuran chorus that is heard is assigned a calling index.
1 - Calls isolated, not overlapping
2 - Some calls overlapping
3 - Calls continuous, overlapping
All data is entered into a Tennessee database in GIS and also entered into the national NAAMP database. The data can be searched and queried by route number, date, calling index or other combination of factors.
New county records are documented with a digital recording. New records will be submitted to the Tennessee Amphibian Atlas and Herpetological Review to be published. In 2005, 18 new county records were submitted and approved.
