MINNEAPOLIS (WCCO) — The Minnesota Department of Natural Resources is looking for volunteers to help with its annual frog and toad calling survey — where you sit out in nature, simply listen and record what you hear.
DNR Spokeswoman Heidi Cyr says participants will conduct nighttime listening surveys around the state to help keep track of frog populations.
Frogs are a good indicator of what’s going on with our environment, according to Cyr.
“If you have a sharp drop in frogs and toads, it may be an indication that there are pollutants or other factors taking place in the population that we should be looking into,” said Cyr.

Frog listeners are equipped with a CD ahead of time so they can learn the croaks and calls of the different species.
The nighttime listening surveys will be conducted on three evenings between April and July.
Anyone who would like to participate can register on the Minnesota DNR’s website.
