Amphibian monitoring allows scientists to understand where amphibians live and how many there are. Monitoring methods can vary. Because some amphibians produce vocalizations, such as frog and toad "frog calls," it is possible to determine what species live at a location by listening for the unique vocalization of a particular species. Other methods include sampling methods such as observation or capture.
Given their sensitivity to environmental changes, amphibians are excellent indicators of environmental health. For this reason, the U.S. Department of Interior takes special interest in amphibian monitoring. Department of Interior organizations such as the National Park Service, Fish and Wildlife Service, and U.S. Geological Survey all contribute to amphibian monitoring. In addition, state government, academic institutions, and conservation organizations such as the National Wildlife Federation work to monitor amphibian populations. This page highlights amphibian monitoring methods, initiatives, and activities in the southeastern U.S.
