Parent organization Affiliations, Website The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List), founded in 1964, is the world's most comprehensive inventory of the global status of. The (IUCN) is the world's main authority on the conservation status of species. A series of are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The IUCN Red List is set upon precise criteria to evaluate the risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. The aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction. According to IUCN (1996), the formally stated goals of the Red List are (1) to provide scientifically based information on the status of species and subspecies at a global level, (2) to draw attention to the magnitude and importance of threatened biodiversity, (3) to influence national and international policy and decision-making, and (4) to provide information to guide actions to conserve biological diversity.
Major species assessors include, the (the research division of the ), the, and many Specialist Groups within the (SSC). Collectively, assessments by these organizations and groups account for nearly half the species on the Red List. The IUCN aims to have the category of every species re-evaluated every five years if possible, or at least every ten years.
This is done in a manner through IUCN Species Survival Commission (SSC) Specialist Groups, which are Red List Authorities responsible for a species, group of species or specific geographic area, or in the case of, an entire class. The percentage of species in several groups which are listed as critically endangered, endangered, or vulnerable on the 2007 IUCN Red List. 1964 Red List of Threatened Plants The 1964 IUCN Red List of Threatened Plants used the older pre-criteria Red List assessment system.

Plants listed may not, therefore, appear in the current Red List. IUCN advise that it is best to check both the online Red List and the 1997 plants Red List publication.

2006 release The 2006 Red List, released on 4 May 2006 evaluated 40,168 species as a whole, plus an additional 2,160, aquatic, and. 2007 release On 12 September 2007, the (IUCN) released the 2007 IUCN Red List of Threatened Species. In this release, they have raised their classification of both the ( Gorilla gorilla gorilla) and the ( Gorilla gorilla diehli) from to, which is the last category before, due to and, along with other factors., chief of -based IUCN's Primate Specialist Group, stated that 16,306 species are endangered with extinction, 188 more than in 2006 (total of 41,415 species on the Red List). The Red List includes the ( Pongo abelii) in the Critically Endangered category and the ( Pongo pygmaeus) in the Endangered category. 2008 release The 2008 Red List was released on 6 October 2008, at the IUCN World Conservation Congress in, and 'has confirmed an extinction crisis, with almost one in four mammals at risk of disappearing forever'. The study shows at least 1,141 of the 5,487 mammals on Earth are known to be threatened with extinction, and 836 are listed as.
2012 release The Red List of 2012 was released 19 July 2012 at; nearly 2,000 species were added, with 4 species to the extinct list, 2 to the rediscovered list. The IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction. With 3,947 described as 'critically endangered' and 5,766 as 'endangered', while more than 10,000 species are listed as 'vulnerable'. At threat are 41% of amphibian species, 33% of reef-building corals, 30% of conifers, 25% of mammals, and 13% of birds.
The IUCN Red List has listed 132 species of plants and animals from India as 'Critically Endangered'. IUCN Red List Categories. Species are classified by the IUCN Red List into nine groups, specified through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. 1994 IUCN Red List categories (version 2.3), used for species which have not been reassessed since 2001.
In 1997, the IUCN Red List came under criticism on the grounds of (or at least poor documentation) surrounding the sources of its data. These allegations have led to efforts by the IUCN to improve its documentation and data quality, and to include peer reviews of taxa on the Red List. The list is also open to petitions against its classifications, on the basis of documentation or criteria. A editorial defended the Red List's relevance in October 2008.
It has been suggested that the IUCN Red List and similar works are prone to misuse by governments and other groups that draw possibly inappropriate conclusions on the state of the environment or to effect exploitation of natural resources. The Red List and Wikipedia itself can provide a useful tool for identifying threatened species in certain countries; country initiatives and lists include:. See also.

India, a megadiverse country with only 2.4% of the world's land area, accounts for 7-8% of all recorded species, including over 45,000 species of plants and 91,000 species of animals. The country’s diverse physical features and climatic conditions have resulted in a variety of ecosystems such as forests, wetlands, grasslands, desert, coastal and marine ecosystems which harbour and sustain high biodiversity and contribute to human well-being. Four of 34 globally identified biodiversity hotspots: The Himalayas, the Western Ghats, the North-East, and the Nicobar Islands, can be found in India. India became a State Member of IUCN in 1969, through the Ministry of Environment, Forest and Climate Change (MoEFCC). The IUCN India Country Office was established in 2007 in New Delhi. IUCN India works with Members and Commissions to reduce ecosystem and species loss by providing the necessary tools and knowledge to value, conserve and use biodiversity sustainability; enhance governance and policy for better management of ecosystems and habitats, including protected areas; and address challenges related to poverty alleviation, food security and climate change.
