Initiative pages of the “old” IUCN Red List website, which was replaced in 2018. The content of these pages provided a detailed account of the 2004 Global Amphibian Assessment and its 2006 and 2008 update, and the majority of the text was last updated in 2008. The Amphibian Red List Authority of the IUCN SSC Amphibian Specialist Group has compiled this information as a record of this remarkable body of work.
