Content image. Endangered Mountain Yellow-legged Frogs Released into Wild

By: Gallegos, E.; ; May 23, 2014

On May 29, 2014 ARMI biologists Adam Backlin and Elizabeth Gallegos, alongside partners Frank Santana from the San Diego Zoo Institute for Conservation Research and Ian Recchio and Marlowe Robertson-Billet from the LA Zoo and Botanical Gardens, will be releasing 74 captive bred juvenile endangered mountain yellow-legged frogs [Rana muscosa] into the wild in the San Jacinto Mountains, near Idyllwil(...more)
Collaborators Do Restored Wetlands Provide Quality Amphibian Habitat in an Agricultural Landscape?

By: Muths, E; May 22, 2014

The Des Moines Lobe of central Iowa has undergone drastic land-use changes over the last two centuries, with 90% of the state’s wetlands converted primarily by agricultural practices and urban development. The introduction of tile drainage to improve land for agriculture facilitated this conversion and still contributes to the productivity of this agricultural landscape. Consequently, natural wetl(...more)

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.
