In 1989 at the World Congress of Herpetology, scientists expressed concern that amphibian population declines were more than local phenomena and may be a global issue. In 1994, the North American Amphibian Monitoring Program (NAAMP) — a partnership among state, provincial, academic, and nonprofit groups working regionally to gather monitoring data on amphibian populations — was established. Across North America, amphibians have variable life history and natural history features. Therefore, the original goal of the NAAMP effort was to employ several survey approaches and protocols to ensure that all species could be monitored. The first NAAMP protocol to be implemented was a roadside calling survey, with the goal of monitoring anurans (frogs and toads) that make distinctive vocalizations during courtship. Roadside calling surveys are most useful in regions of North America where all (or most) of the anuran species in an assemblage vocalize in a relatively predictable manner. Further research is needed to confirm or refine the seasonal sampling periods and nightly sampling conditions on a regional basis.
