FrogWatch USA is the Association of Zoos & Aquariums' (AZA) flagship citizen science program that allows individuals and families to learn about the wetlands in their communities and help conserve amphibians by reporting the calls of local frogs and toads. Frogs and toads have been vitally important in the field of human medicine and compounds from their skin are currently being tested for anti-cancer and anti-HIV properties. Frogs and toads also play an important role, serving as both prey and predator, in wetland ecosystems and are considered indicators of environmental health.

Many previously abundant frog and toad populations have experienced dramatic population declines both in the United States and around the world and it's essential that scientists understand the scope, geographic scale, and cause of these declines.

FrogWatch USA volunteers learn to identify local frog and toad species by their calls during the breeding season and how to report their findings accurately. By mastering these skills, volunteers gain increased experience and control over asking and answering scientific questions which, in turn, augments science literacy, facilitates conservation action and stewardship, and increases knowledge of amphibians.
