FrogWatch USA™ is a long-term citizen science monitoring program of frogs and toads.

As a volunteer-based monitoring program, FrogWatch USA™ gives citizens 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.

General information about FrogWatch can be found on the Association of Zoos and Aquarium web site.

You do not have to be a frog or toad expert to be a FrogWatch USA™volunteer. All you need is an interest in frogs and toads and a willingness to participate in a volunteer training session with a commitment to monitor a site for at least three minutes twice a week throughout the breeding season, February through August.

Volunteer Training

Free volunteer training is offered every spring. The training sessions are for students entering grade 9 and adults and cover all the information needed to get started and to join our FrogWatch community. 

All in-person training workshops are on hold until further notice.

To participate in this event, you will need the following:

  • Minimum: computer or smart device with internet access and audio capabilities
  • For the best experience and use of the online platform Zoom, you will need an internet enabled device with speakers, microphone, and camera. If you are using a cell phone or tablet, you will need to download the free Zoom app.

Volunteer Certification

Become a Certified FrogWatch Volunteer!
If you are already a FrogWatch Volunteer, why not take the next step and become a certified FrogWatch volunteer. The certification will give your data more credibility and make it even more useful in accomplishing the goals of FrogWatch USA™. You can become certified by scoring a minimum of 80% on each of the following two assessments administered by your local FrogWatch USA™ Chapter: The FrogWatch Protocol Assessment and the Frog and Toad Call Identification Assessment. To prepare for certification, review the protocols in the FrogWatch Volunteer Manual; practice identifying the frog and toad calls of our Missouri species; and then sign-up online for the next available certification session.
