FrogWatch USA

FrogWatch USA™ is a citizen science program of the Association of Zoos and Aquariums that invites individuals and families to learn about the wetlands in their communities and help conserve amphibians by reporting data on the calls of local frogs and toads. AZA’s FrogWatch USA comprises a national network of skilled coordinators and volunteers that form a community with the common goal of providing large scale, long-term data on frogs and toads in the United States. FrogWatch-FieldScope allows participants to enter and review their data, as well as explore maps and graphs. Use FrogWatch-FieldScope to examine species distribution, timing of calls, and other data geographically and over time and see what you can discover!

If you are new to FrogWatch USA and would like to learn more about volunteering, or are part of an institution or organization interested in starting a chapter, please visit our homepage at www.frogwatch.org.

Project Maps

FrogWatch USA Data Entry

Use this map to enter new data into the FrogWatch USA database.

FrogWatch USA Seasonal Visualization

Use this map to examine seasonal patterns in the FrogWatch USA data. Do the onset and drop-off of amphibian activity exhibit a seasonal pattern such as east-to-west or north-to-south? Do they exhibit the same pattern, or different patterns?

FrogWatch USA Data Discovery

What can we learn from the FrogWatch USA data? Explore relationships among FrogWatch USA monitoring sites, frog and toad calling observations, and other factors such as weather and surrounding land use by following this link and then using the tabs at the upper left side of your screen to switch between the features listed below.

  • The "Map" tab allows you to explore spatial data. Use the various themes (layers) to look at the country or a region as a whole, or zoom in close to investigate features of your wetland site and those nearby. Use the various tools to explore relationships between frog and toad species presence and land use, distances between sites, and other comparisons among sites.
  • The "Calling Calendar" tab allows you to plot the frog and toad calling data at a site and compare it to observations recorded at sites within a 100 mile searchable area. Select a species at a site, add it to the calendar, and see when it was heard calling. Compare call intensities across time and among species to identify patterns and differences.
  • The "Temperature Comparison" tab plots the air temperature recorded during FrogWatch USA monitoring visits and the calling observations made during those visits. This feature allows you to explore the temperatures at which species call at a given site, and compare them to observations recorded at sites within a 100 mile searchable area. Examine the temperature ranges at which species were heard calling. Compare observations at your site with those made at others nearby and across the United States.
