For a variety of reasons (including disease, loss of habitat and pollution) the world's frogs and other amphibians are rapidly disappearing. Recent estimates suggest that nearly one-third of the world's amphibian population is facing extinction and that 168 species have already gone extinct in the last two decades.

Coordinators of Global Amphibian Blitz are calling on citizen scientists to help arrest this problem by taking stock of amphibian populations worldwide. This includes observing, photographing and recording information about local amphibians. Images can be posted to the Global Amphibian Blitz Web site and amphibian locations are plotted on a world map. In the project's first week alone, researchers say they were able to locate 303 distinct species worldwide—4.4 percent of the 6,815 amphibian species on this planet.

In order to protect rare species when they are identified, iNaturalist.org obscures specific locations to protect the amphibians from those who might harm them. Public coordinates describing the locations of species whose names appear on the International Union for Conservation of Nature and Natural Resources "Red List"—at high risk for global extinction—are obscured by about 5 kilometers. The reporting citizen scientist, however, does see the exact coordinates of his or hear observation.
