Monitoring Protocol

The FrogWatch USA™ volunteers must complete four hours of training (see Training Schedule).  They use the following protocol when monitoring frogs from February through August:


  1. Review the local frog and toad calls.
  2. Conduct an evening monitoring visit, at least 30 minutes after sunset
  3. Document the weather conditions - wind speed, temperature, recent moisture, etc.
  4. Wait at least 2 minutes to let the frogs acclimate to your presence.
  5. Listen for precisely 3 minutes.
  6. Write down species and calling intensities heard.
  7. Submit your data!
  8. Repeat: Monitor multiple times from February through August.

Data will be submitted on the Frog Watch Field Scope (FWFS) website.
