Minnesota Frog & Toad Calling Survey (MFTCS)

MFTCS logoThe DNR's Nongame Wildlife Program is sponsoring an ongoing state-wide study of Minnesota's frogs and toads. Since 1996, volunteers across Minnesota have collected data by listening to and identifying frog and toad species on specified 10-stop routes. The results of this ongoing study will provide information on where species are located throughout the state, and how their populations change in abundance and distribution.
