Program Summary

The Minnesota Frog and Toad Calling Survey was a citizen science program sponsored by the DNR's Nongame Wildlife Program to monitor frog and toad populatons statewide.  From 1994-2017, volunteers across Minnesota collected data by listening to and identifying frog and toad species on specified 10-stop routes. The results of this study provided valuable information on the locations of species throughout the state and on changes in population abundance and distribution over time.  This program concluded at the end of the 2017 season.

Next Steps

In the coming months, we will be working on compiling and analyzing the data collected in 2016 and 2017 to give us some insights into the health of our state's frog and toad population.  Once that analysis is done, we will post the final report to this webpage.  We will also be looking at options to continue to monitor frog and toad populations. 

Thank You

We greatly appreciate all of the volunteers for their enthusiasm, expertise, and tireless dedication over the past 24 years of the program.
