"The 2006 figures for amphibians are those that were agreed at the Global Amphibian Assessment (GAA) Brazil workshop in April 2003. Figures in the table will not completely match figures shown in the Global Species Assessment."

Technical Notes
"Definition:"
"Animal species, number extinct, includes all species of animals that are listed as extinct by the World Conservation Union (IUCN) and that are known to occur in a given country.  Extinct species data include species listed as ""Extinct"", or ""Extinct in the Wild."" Data include unconfirmed species occurrences and regionally extinct species, but exclude sub-species and introduced species. This data set only includes species that are known to have become extinct since 1500 AD. "
""

""
"See the ""Methodology"" section below for further information."
""
""
""
"Years Covered and Frequency of Update:"
"This data set provides current extinct species data as of May, 2006. Extinct species data are updated by IUCN on a continual basis as new data become available. The IUCN Red List of Threatened Species is typically published on an annual basis."
""
"Methodology:"
"Adapted from the IUCN Red List of Threatened Species Information Sources & Quality notes and 2001 Categories & Criteria (v. 3.1)."
""
"The information presented in the current IUCN Red List represents an accumulation of knowledge derived from previously published Red Lists, including the 1996 IUCN Red List of Threatened Animals and The World List of Threatened Trees. In some cases assessments are the product of group discussion, but often they represent the judgment of individual Specialist Group members. In order to ensure greater accuracy and transparency in the listing process, a peer review system of Red List Evaluators was initiated. The intention of the system is that the assessments of all species on the Red List are scrutinized and evaluated by at least two people from a designated Red List Authority. The Red List Authorities are responsible for ensuring that all species they are responsible for are documented and re-assessed at regular intervals."
""
"Undescribed species are only included on the IUCN Red List of Threatened Species under certain specific conditions, including the undescribed taxon is in fact a good species, clear distribution information can be provided, and listing the undescribed species will potentially aid in its conservation."
""
""
"A brief description of the IUCN system to assess risk of extinction is provided below.  For more detailed information please refer to the original source at: http://www.redlist.org/info/categories_criteria2001.html."
""
"The IUCN states, ""a taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon's life cycle and life form."""
""
""
""
"""A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon's life cycle and life form."""
""
""
""
"Further documentation is required for extinct species indicating the date of extinction, cause(s) of extinction, and survey protocols which have been initiated to search for the species. The starting date for the inclusion of extinctions has been moved to 1500 AD to coincide with the starting date used by the Committee on Recently Extinct Organisms (http://creo.amnh.org/)."
""
"Data Reliability:"
"The total number of extinct animals is an underestimte of the total number of extinct animals worldwide. There are two reasons in particular: amongst the groups of described animals, assessments were not undertaken for many species due to lack of data, resources, or for other reasons; beyond the list of known animals, there are a number of undocumented animals whose status is yet unknown."
""
"Where possible, standard world checklists have been used in order to promote nomenclatural stability. In a few instances Specialist Groups have used alternative systematic opinion and provided justification for doing so. Data on known species of mammals, birds, fish, molluscs, reptiles, amphibians, and plants are based on a compilation of available data from a large variety of sources, collected over the last decade. Additionally, while the number of species in each country does change, not all countries are updated systematically, and some data may not reflect recent trends."
