I assume they’re referring to how the presence of frogs is an indicator as to the cleanliness of the water. If the river is highly polluted no frogs will be present.
I personally only visit neighbourhoods where the frogs respond to my chirp of greeting by rolling around on their backs and allowing me to pet their tummies

This is precisely what I meant, and I’m glad it came across. 💙
