The Wisconsin Department of Natural Resource’s Frog and Toad Survey is the longest running survey of its kind in the country. Every spring and summer, thousands of citizen scientists strike out on routes all over the state to listen for the breeding calls of Wisconsin’s eleven frog and one toad species. Perpetual Notion Machine host Catherine Garvens brings you an overview of these efforts. We’ll hear from volunteers as they run their routes, and from folks at the Wisconsin DNR who work to organize the survey and collect the data. And, we’ll listen to some frogs and toads along the way.
