Michigan: listen for frogs and toads this spring

You can help track frog and toad population trends in Michigan by listening for their calls this spring. Data is collected throughout the state, and anyone who is interested is welcome to participate. Frog and toad survey data collection takes place April through July, so now is the perfect time to plan your survey route and brush up on frog and toad calls!

Find the frog and toad survey instructions and route description form, along with calls and other information, on our Michigan’s Frogs and Toads page.

Email DNR-FrogSurvey@Michigan.gov with your survey route or questions. New survey routes should be submitted by April for approval. Survey routes should include 10 different stops that will be surveyed three times during the survey period.
