Title North American Amphibian Monitoring Program

Project Description The North American Amphibian Monitoring Program (NAAMP) was created as a large-scale

program to monitor the status and trends of anuran (frog and toad) populations. The survey

methodology was based upon prior survey effort, primarily the Wisconsin Frog and Toad Survey

that was initiated in 1981. The method adopted was a roadside calling survey, with multiple

listening stations where anurans are identified by vocalizations during the breeding season.

Stratified random roadside surveys are conducted three to four times per year, depending on the

species assemblage of a region. The protocols of the calling survey were designed for species of

the eastern half of North America, where anurans vocalize in a relatively predictable manner.

NAAMP is a collaborative effort among many partner organizations working regionally and the

U.S. Geological Survey. The USGS Patuxent Wildlife Research Center provides central

coordination and administrative support. NAAMP regional partners include state government

agencies, academic professionals, and non-profit organizations. The NAAMP website is:
