North American Amphibian Monitoring Program

The North American Amphibian Monitoring Program (NAAMP) is a collaborative effort among regional partners, such as state natural resource agencies and nonprofit organizations, and the U.S. Geological Survey (USGS) to monitor populations of vocal amphibians. The USGS provides central coordination and database management. The regional partners recruit and train volunteer observers, like you, to collect amphibian population data, following the protocol of the NAAMP. Amphibian population data are collected using a calling survey technique, in which observers identify local amphibian species by their unique vocalizations. Not all amphibian species make vocalizations, but many frogs and toads do. Observers are trained to identify their local species by these unique vocalizations or "frog calls."
