The frog and toad listeners that partake in the DNRs annual Frog and Toad
Survey are a little like the horse whisperers. Both tend to the health
and well-being of a species.
The listeners, who cover over 500 routes statewide throughout every
Michigan county, listen to the calls of the frogs and toads at 10 sites
three times each spring and early summer. They identify the species
present and make an estimate of their abundance. Reports are sent to the
state which correlates the findings and the health of our states
This is our 16th year doing the annual survey, said Lori Sargent, the
DNRs longtime survey coordinator. Weve been collecting valuable data
to help evaluate Michigans frog and toad population. Its way too early
to tell much about long-term trends, but this is a good start.
