• What is the Frog & Toad Survey?
Michigan is home to 13 native species of anurans (frogs and toads). There is concern about apparent declines and other population changes of several of these species. The Michigan Frog and Toad Survey was initiated in 1988 to increase our knowledge of anuran abundance and distribution and to monitor populations over the long term.
