The North American Amphibian Monitoring Program (NAAMP) was a collaborative citizen science effort between the US Geological Survey (USGS) and 25 partners (state agencies, universities, and nonprofit organizations) for monitoring calling amphibian populations over much of the eastern and central United States. Initiated in 1997, NAAMP was designed to provide scientifically and statistically defensible, long-term distribution and trend data for calling frog and toad populations at both the state and regional level.

Modeled after the North American Breeding Bird Survey, NAAMP utilized a network of random roadside routes with multiple stops where volunteers listened for amphibian vocalizations as indicators of species occurrence. Data collection under a unified protocol began in 2001 and continued through 2015 with the addition of observer assessment scores (FrogQuiz) in 2006. The USGS funded the Patuxent Wildlife Research Center (PWRC, website: approximately $150K/year to support central coordination and data management for the program, while state partners recruited, trained, and coordinated over 1,000 volunteer observers who conducted over 16,000 surveys.

Given resource constraints, the USGS decided to end its role as the National Coordinator of NAAMP at the conclusion of the 2015 season. The USGS reached out to various organizations in an attempt to find a new home for long-term program coordination and data management, but none agreed to do so and the program is currently being curtailed. The PWRC cannot accept data collected after 2015 and will archive all vetted data (2001-2015) in late CY2016. Archived data will remain publicly available for continued use and the PWRC is currently conducting trend analyses of the data as part of the closeout.

The USGS and PWRC greatly appreciate all of the NAAMP volunteers and state partners who dedicated their time, expertise, and enthusiasm over the last 18 years in an effort to provide the conservation and management communities with valuable long-term information regarding frog and toad population trends.

Volunteers, in the absence of NAAMP, please contact your state coordinator regarding continued frog and toad monitoring opportunities within your state.
