Amphibians- the broader view

This update on the big picture of amphibians mixes reports of critical concern with pockets of hope. International efforts like the Amphibian Ark are trying desperately to save species that may no longer be viable in the unprotected wild. In the last four years, 366 species have been added to the IUCN's Red List. At the same time, new discoveries keep hopping into view. Herpetologist Claude Gascon says, "There are now about 6,200 species - that's 10% more than we had five years ago, and that's probably between 50% and 75% of what there is, because a lot of places remain to be explored. In Papua, New Guinea and Madagascar, for example, there are probably as many species waiting to be discovered as we know of now."
