    There is no definitive answer, but according to the IUCN Red List, 1996 saw a large increase in the evaluation of potentially endangered species. As a result, after 5,205 species were examined, 25% of all mammals and 11% of all birds were officially listed as threatened. This action would conceivably be the year with the most additions to the list.
