Amphibians in Dramatic Decline; Nearly One in Three Faces Extinction
Global Amphibian Assessment Findings Published in Science (10.14.04)
The world’s amphibian species are under unprecedented assault and are experiencing tens of thousands of years worth of extinctions in just a century, according to the most comprehensive study ever conducted. More than 500 scientists from over 60 nations contributed to the Global Amphibian Assessment, the key findings of which were published online by Science Express on October 14, 2004, and
subsequently in the journal Science dated December 3, 2004
Over the past three years, scientists from Conservation International, IUCN-The World Conservation Union, and NatureServe analyzed the distribution and conservation status of all 5,743 known amphibian species—which include frogs and toads, salamanders, and caecilians. Of these, 1,856 (32 percent) are now considered threatened with extinction. Sufficient data are lacking to accurately assess the status of nearly 1,300 other species, most of which scientists believe are also threatened.
Complete data about each species, as well as country and regional breakdowns, are available in a searchable database at www.globalamphibians.org.
