The biodiversity data are presented for context; they do not represent a true indicator. The figures show the proportion of the world’s species that occur in this country. Countries with many endemics have particular responsibility for preventing their extinction because no other country can protect them. The number of species in a country depends on many factors such as the size of the country, the diversity of habitats, the distance from the equator, the topographic complexity and whether the country is on an island or continent. The proportion of species in a country that are globally threatened is also the result of many factors, including the range sizes of species occurring there (tropical species tend to have smaller ranges than temperate ones), the amount of conversion of natural habitats to other land uses, the extent of protected areas, the intensity of trade in wild plants and animals, and conservation conditions in surrounding countries.
By 2020 the extinction of known threatened species has been prevented and their conservation status, particularly of those most in decline, has been improved and sustained.
These data are available globally.
This indicator reflects the most recent version of the IUCN Red List of Threatened Species. See How can I download the source data and get more information about them? for the version number.
This indicator was developed using the 2015-4 version of the IUCN Red List of Threatened Species. The database indicates, for all species, the countries where the species occurs. The calculation included only species definitely recorded in the country as either a permanent resident, migrant, or vagrant. Species are included only in the countries for which they are recorded as native. Species classified as Extinct (EX) or Extinct in the Wild (EW) are counted as part of a country’s diversity. Endemic species are those that are only recorded as being native in a single country.

Scientists are constantly discovering and naming new species. The data represent species that have been formally described, assessed for their extinction risk and published on the Red List. Thus some recently described species are currently missing from the database, and will be included as they are assessed and published on the Red List. New versions of the Red List are published approximately three times each year.
Some species that are not globally threatened may still be nationally or regionally threatened and in need of conservation efforts to prevent extirpation. The information provided here reflects global threat levels only.
