Amphibian Declines

During the 1970s and 1980s, researchers in many parts of the world reported seemingly drastic population declines and disappearances of amphibians. If, as is widely accepted, amphibians are reliable bioindicators of environmental change, then these population declines had to be regarded as early warnings signaling an important biodiversity crisis. The scientific community responded by forming the Declining Amphibian Populations Task Force in December 1990 under the aegis of the Species Survival Commission of IUCN — The World Conservation Union — with the support of the international herpetological community. Its purpose is to organize and coordinate a global investigation of unexplained (and sometimes conflicting) data indicating amphibian population and species declines and worldwide disappearances. The Task Force operations are linked to the greater conservation community through the IUCN and the international DIVERSITAS program; these links ensure that the broader implications of the amphibian declines will be given appropriate attention.
