Amphibian Red List Authority

The Amphibian Red List Authority (ARLA) is the branch of the Amphibian Specialist Group (ASG) responsible for maintaining the amphibian extinction risk assessments on The IUCN Red List of Threatened Species. Drawing on the expertise of the global ASG network, we are committed to assessing the conservation status of every amphibian species in the world.
