The 2016 ARMI meeting was held at the National Wildlife Health Center (NWHC) in Madison, Wisconsin. ARMI scientists met with disease researchers from NWHC to develop a new disease strategy designed to meet the need for increased information on how aspects of the environment can be managed to understand and reduce the effect of disease on amphibian populations. Disease has been an integral part of (...more)
Spotted newt ARMI conducts national survey for salamander chytrid fungus

By: Waddle H; October 12, 2016

In 2016 ARMI and National Wildlife Health Center scientists conducted a nationwide sampling effort to detect the salamander chytrid fungus Batrachochytrium salamandrivorans (Bsal). Bsal is native to Asia where indigenous salamanders carry the fungus without disease symptoms. However, Bsal has been spread through human facilitation to Europe where it has been implicated in major population(...more)
Sierra Nevada yellow-legged frog in Yosemite National Park Hopeful findings for an endangered frog in California’s Sierra Nevada

By: Kleeman P; October 05, 2016

New research combining long-term data sets from UC Santa Barbara biologist Roland Knapp and Emeritus ARMI biologist Gary Fellers shows that after decades of decline — and despite continued exposure to stressors including non-native fish, disease and pesticides — the abundance of endangered Sierra Nevada yellow-legged frogs (Rana sierrae) has increased seven-fold throughout Yosemite, and at (...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.
