FrogWatch USA

FrogWatch USA™ is a long-term community science monitoring program of frogs and toads. As a volunteer-based monitoring program, FrogWatch gives people across the country an opportunity to be directly involved in gathering information that can ultimately lead to practical and workable ways to stop amphibian decline.

Join the Saint Louis Zoo FrogWatch Chapter

You do not have to be a frog or toad expert to help with frog conservation. All you need is an interest in frogs and toads and a willingness to participate at the level of commitment that works for you.

Our FrogWatch community offers several great ways to get involved in our FrogWatch program with different levels of training and time commitment. You have the option to help collect data about our frog and toad populations as a user of iNaturalist (FrogWatch-Lite) or as a FrogWatch volunteer.

Virtual FrogWatch-Lite Webinar

Trainings for FrogWatch-Lite will include an introduction to the most common Frogs and Toads of the Saint Louis Area, basic auditory identification, how to use the community science platform iNaturalist, and different ways you can get involved in the Saint Louis FrogWatch community.

Spring Peeper Program

The Saint Louis Zoo WildCare Institute Spring Peeper Program is working to identify remaining populations of urban frogs and toads in the watersheds located within the Interstate 270 beltway. Causes for the decline of spring peepers, boreal chorus frogs and cricket frogs in these areas are currently being studied with the hope of reestablishing viable and sustainable breeding populations in the future. Data from FrogWatch St. Louis volunteers may contribute to this conservation program.
