‘So many connections:’ Chicago indicator species are trying to tell us something

A Curious City listener wanted to know about the decline of frogs in our area. We looked into what’s been happening with these species over the last couple decades in Chicago. It turns out, frogs are some of the animals we call “indicator species.” How well or poorly they’re doing in their habitat can tell us about the health of our own. And they’re not the only ones; there are numerous plants and animals that serve as nature’s alarm system, so to speak. Erin Allen talks with conservation researcher, Dr. Allison Sacerdote-Velat, about the indicator species that are most vital to us in the Chicago area and why we should be paying attention.
