The project's own page notes that there are ten times as many amphibian species known to science today than were known in the mid-1980s. [3] In July 1999, the catalogue was first published on the internet, in its 2.0 version. New versions were added in 2004, 2006 and 2007. The 6.0 version, published in 2014, allows for real-time modifications. [4]
We find that amphibians are the most threatened vertebrate class (40.7% of species are globally threatened). The updated Red List Index shows that the status of amphibians is deteriorating globally, particularly for salamanders and in the Neotropics. Disease and habitat loss drove 91% of status deteriorations between 1980 and 2004.
