Minnesota Frog & Toad Calling Survey (MFTCS)

The 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.

Recruitment for the 2009 survey has ended. CLICK HERE for a map of currently available route locations in the state for the 2010 survey. Please contact Krista Larson at krista.larson@state.mn.us or 651-259-5120 if you are interested in participating.
