ARMI Mission Statement

In response to indications of worldwide declines in amphibian populations, the President and Congress directed Interior Department agencies to initiate a national program of amphibian monitoring, research, and conservation. There is an urgent need to determine the scope and severity of the problem and to investigate causes. The U.S. Geological Survey is uniquely qualified to coordinate and lead a cooperative national effort because its scientists have been in the forefront of studying amphibian populations and life history traits, measuring and monitoring environmental characteristics, and conducting research into potential causes of decline. As a result, the Agency formed the National Amphibian Research and Monitoring Initiative (ARMI).

ARMI Goals and Objectives

  • » Provide information to natural resource managers on the status and trends of amphibians
  • » Relate status and trends to management options at the scale of management units.
  • » Identify causes of declines.
  • » Provide essential scientific information to support effective management actions to arrest or reverse declines.
