Lost Frogs
The Top 10 Most Wanted
The Search for Lost Frogs is an unprecedented global search for species believed “lost” to science. Launched in August 2010 by the ASG and Conservation International the campaign was intended to run for several months, but garnered such attention that it has inspired us to develop a dynamic portal devoted to the ongoing search for “lost” frogs.
Join scientists as they trek remote jungles and wade up streams in search of some of the most elusive animals and check back to find out if any more of our “top-ten” most wanted species have been found.
The Search for Lost Frogs, launched in August 2010 by the IUCN SSC Amphibian Specialist Group (ASG) and Conservation International (CI), with support from Global Wildlife Conservation (GWC), sought to document the survival status and whereabouts of threatened amphibian species not seen in over a decade. Below is the current list of “lost” amphibians. Phase 1 of the Search for Lost Frogs ended in 2011 but the campaign is not over with individuals and groups launching expeditions to find these species on an increasingly regular basis. We are eager to hear from anyone who has information on any of the below species or is planning a search.
Over the course of the next two weeks are inviting species nominations to replace the three “lost” species on the list. We are also eager to hear of any species that you feel should be included on the below more complete list. Please email Robin Moore with your nominations of species you believe deserve to be featured, by February 14, including details on last time seen, any previous (or planned) searches for the species, any unusual or interesting features and any images/illustrations/video you know of. Please contact Robin Moore with any information or questions you might have.
