IUCN Red List Categories: EX - Extinct, EW - Extinct in the Wild, CR - Critically Endangered, EN - Endangered, VU - Vulnerable, LR/cd - Lower Risk/conservation dependent, NT - Near Threatened (includes LR/nt - Lower Risk/near threatened), DD - Data Deficient, LC - Least Concern (includes LR/lc - Lower Risk/least concern).

** It should be noted that for certain amphibian species endemic to Brazil, there was not time to reach agreement on the Red List Categories between the Global Amphibian Assessment (GAA) Coordinating Team, and the experts on the species in Brazil. The 2006 Red List Categories for amphibians displayed here are those that were agreed at the GAA Brazil workshop in April 2003. However, in the subsequent consistency check conducted by the GAA Coordinating Team, many of these were found to be inconsistent with the approach adopted elsewhere in the world, and a "consistent Red List Category" was also assigned to these species. There was not time to agree these "consistent Red List Categories" with the Brazilian experts before the release of the IUCN Red List, therefore the original workshop assessments are retained here. However, in order to retain comparability between results for amphibians with those for other taxonomic groups, the data used in the Global Species Assessment (Baillie et al. 2004) are based on the "consistent Red List Categories". Therefore, figures in table 3a above will not match figures in table 2.2 in the Global Species Assessment.
