The tiger has been listed as Endangered on the IUCN Red List since 1986 and the global tiger population is thought to have continuously declined from an estimated population of 5,000–8,262 tigers in the late 1990s to 3,726–5,578 individuals estimated as of 2022. [1]
The IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system. [ 8 ] Over 50% of the world's species are estimated to be at risk of extinction, [ 9 ] but the frontier between categories such as 'endangered', 'rare', or 'locally extinct' species is often difficult to draw given the general ...
In east Africa, threats to populations include overfishing, reductions in water quality due to agricultural activities and deforestation, and pesticide pollution. [1] According to the IUCN Red List of Threatened Species , tigerfish are of least concern with a wide distribution but are protected in some reserves.
The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit; [17] nearly 2,000 species were added, [18] with 4 species to the extinct list, 2 to the rediscovered list. [19] The IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction.
They are distributed throughout Africa, the Indian subcontinent and southeast Asia, and are usually found in habitats such as savannas, forests, grasslands and shrublands. Pholidotans range in size from the giant pangolin, at 30 kg (66 lb) and 68 cm (27 in) in length, to the tree pangolin, at only 2.3 kg (5.1 lb) and 34 cm (13 in) in length.
The IUCN also lists 60 mammalian subspecies as critically endangered. Of the subpopulations of mammals evaluated by the IUCN, 18 species subpopulations have been assessed as critically endangered. Additionally 900 mammalian species (15% of those evaluated) are listed as data deficient , meaning there is insufficient information for a full ...
Please stick to IUCN Red List Critically Endangered Animalia when you add or remove species, subspecies, stocks or sub-populations. Binomial and trinomial nomenclature should be used, no more. To get more clarity, surname of scientific authority should be ignored.
The IUCN also lists 86 mammalian subspecies as endangered. Of the subpopulations of mammals evaluated by the IUCN, five species subpopulations have been assessed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction".
