Current FrogWatch USA Volunteers

Welcome back and thank you for your support! AZA recognizes that your continued participation helps FrogWatch USA meet its educational and scientific goals and helps AZA meet one of its primary aims: connecting people with nature. Your previous experience as a FrogWatch USA volunteer and continued participation in this important citizen science program is fundamental to sustaining the program and collecting long-term data on the nation's frogs and toads.

Enter and Review Data Online

FrogWatch USA offers an engaging online data entry and exploration platform to give FrogWatch USA participants -- and anyone interested in frogs and toads -- the opportunity to interact with the program's data. While anybody can explore data through graphs or maps without being logged in, creating an account allows you to enter data, edit it, and save and share any maps and graphs you create.

Log in to the online data entry and exploration system, FrogWatch-FieldScope.

Data Recording

When completing your datasheets, please be sure to report all data, including monitoring visits when zero frog or toad calls were heard. Information about the absence of calls is just as valuable as information about their presence. It is essential that you follow the standardized FrogWatch USA monitoring protocols. Limit monitoring visits to February through August (or September in the southwestern United States). Data are to be collected in the evening, at least 30 minutes after sunset and conclude by 1:00 AM. The required listening period is 3 minutes in duration. Data are recorded on a FrogWatch USA datasheet and entered online to the FrogWatch USA data entry system. If unable to submit data online, contact AZA for additional support by emailing

If email is not available, correspondence may be sent via U.S. mail to:

FieldScope is an online data entry, mapping, and analysis platform developed by the National Geographic Society specifically for citizen science programs like FrogWatch USA. A National Science Foundation Informal Science Education grant supported the development of this platform, encouraging people to input the important data they collect and to visualize those data across space and time.

Prepare for the Upcoming Season

Practice Identifying Local Frog and Toad Calls

It is imperative that data are only submitted for species that you feel confident were identified correctly in the field. During the fall and winter, and before the FrogWatch USA season begins, refresh your memory about the frog and toad calls you will hear in your area by reviewing the Frogs and Toads by State List and and testing your call identification skills.

Other sources for locating frog and toad species information and calls include: AmphibiaWeb, Cornell Lab of Ornithology Macaulay Library, and Western Soundscape Archive. Many state and local resources are also available including, but not limited to, these for Arkansas, California, Florida, Georgia and South Carolina, Maryland, North Carolina, and Virginia.

Review Monitoring Protocols

AZA is dedicated to maximizing the scientific value of the data being collected through FrogWatch USA's standardized data collection protocols. Although it is up to you how often your site is monitored, it is recommended that each site be monitored twice a week throughout the breeding season. At least four visits spread throughout the peak frog and toad breeding season (February through August) is recommended for trend analysis. Before starting the season, be sure to review the FrogWatch USA monitoring protocols.

Monitor Your Wetland Sites

FrogWatch USA wetland sites and data are available online through FrogWatch-FieldScope and you should review and confirm accuracy of previously submitted sites. If you are unable to edit a site registered by you, please use the flagging feature and submit a detailed comment for AZA review. Email if you cannot locate a previously-registered site. If you would like to monitor a new site you should follow these instructions to register your wetland site online, or download a site registration form and submit it via email. Review our tips for selecting a suitable wetland site in your community.
