Frogs play a vital role in the wetland ecosystem and are considered bio-indicators of the health of the environment. This is the second year we will be monitoring frog populations at Schlitz Audubon. Join us out in the field to learn how to identify frog species by their call and learn how you can help with this citizen science project. We will meet in the main building and then head out on the trails. FrogWatch USA is a citizen science program from the Association of Zoos and Aquariums (AZA).
