Wisconsin Frog and Toad Survey

Green frog.

The main goal of this survey is to determine the status, distribution and long-term population trends of Wisconsin's twelve frog species. Annual statewide surveys began in 1984, and it is now one of the longest running amphibian monitoring projects in North America. Participants choose an established route and conduct three night-time surveys a year: in the early spring, late spring and summer. No formal training is necessary, but volunteers are asked to follow a simple protocol, fill out, submit data sheets and familiarize themselves with the different frog calls. Get Involved (exit DNR).
