John Ball Zoo FrogWatch Chapter

FrogWatch USA is a citizen science program of the Association of Zoos and Aquariums (AZA). John Ball Zoo hosts an active chapter.

You don’t have to be an expert to join in FrogWatch and help contribute valuable information to scientists studying amphibians! This citizen science program provides individuals, groups and families the opportunity to learn about wetlands in their communities and report data on the calls of local frogs and toads.

Volunteers are asked to attend at least one training session; learn the importance of amphibians, identify frog species by their calls and, observe frogs in your area. We ask that volunteers commit to collecting data approximately once a week for about 10 mins during the season. Formal volunteer training sessions are offered in February and March with field trainings in the spring and early summer. For more information please visit
