The Declining Amphibian Populations Task Force (DAPTF) was established in 1991 by the Species Survival Commission (SSC) of the World Conservation Union (IUCN). The DAPTF operates through a network of Working Groups like the California/Nevada Working Group. Over 80 of these Working Groups represent different regions of the world and collect geographical data on amphibian declines and their causes. Other, issue-based Working Groups are concerned with specific topics, including: Disease and Pathology, Monitoring Techniques, Chemical Contaminants, and Climatic and Atmospheric Change. Task Force members and other interested parties are kept up to date via the newsletter FROGLOG.
