The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
The tamaraw or Mindoro dwarf buffalo is a small hoofed mammal belonging to the family Bovidae. It is endemic to the island of Mindoro in the Philippines, and is the only endemic Philippine bovine. It is believed, however, to have once also thrived on the larger island of Luzon. The tamaraw was originally found all over Mindoro, from sea level up to the mountains, but because of human habitation, hunting, and logging, it is now restricted to only a few remote grassy plains and is now a critically endangered species.
Threatened species are any species which are vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment.
Kniphofia is a genus of perennial flowering plants in the family Asphodelaceae, first described as a genus in 1794. Species are native to Africa. Common names include tritoma, red hot poker, torch lily and poker plant.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
Conservation in New Zealand has a history associated with both Māori and Europeans. Both groups of people caused a loss of species and both altered their behaviour to a degree after realising their effect on indigenous flora and fauna.
The northern hairy-nosed wombat or yaminon is one of three extant species of Australian marsupials known as wombats. It is one of the rarest land mammals in the world and is critically endangered. Its historical range extended across New South Wales, Victoria, and Queensland as recently as 100 years ago, but it is now restricted to one place, a 3 km2 (1.2 sq mi) range within the 32 km2 (12 sq mi) Epping Forest National Park in Queensland. With the species threatened by wild dogs, the Queensland Government built a 20-kilometre (12 mi)-long predator-proof fence around all wombat habitat at Epping Forest National Park in 2002.
The Santa Cruz cypress is a species of North American tree within the Cypress family. The species is endemic to the Santa Cruz Mountains within the Santa Cruz and San Mateo counties of west-central California. The U.S. Fish and Wildlife Service listed the species on the Endangered Species Act in 1987 due to increasing threats from habitat loss and disruption of natural forest fire regimes. In 2016, the conservation status of the Santa Cruz cypress changed to Threatened. The cited reasoning was a decrease in threats against their habitat.
Calendula maritima, known as the sea marigold and trailing calendula, is a very rare species from the family of Asteraceae. Some scientists regarded it as Calendula suffruticosa subspecies maritima.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be Critically Endangered.
The western swamp turtle or western swamp tortoise is a critically endangered species of freshwater turtle endemic to a small portion of Western Australia. It is the only member of the genus Pseudemydura in the monotypic subfamily Pseudemydurinae.
The Threatened Species Protection Act 1995, is an act of the Parliament of Tasmania that provides the statute relating to conservation of flora and fauna. Its long title is An Act to provide for the protection and management of threatened native flora and fauna and to enable and promote the conservation of native flora and fauna. It received the royal assent on 14 November 1995.
Translocation in wildlife conservation is the capture, transport and release or introduction of species, habitats or other ecological material from one location to another. It contrasts with reintroduction, a term which is generally used to denote the introduction into the wild of species from captive stock. The International Union for the Conservation of Nature (IUCN) catalogues translocation projects for threatened species around the globe.
The Raffles' banded langur, also known as the banded leaf monkey or banded surili, is a species of primate in the family Cercopithecidae. It is endemic to Singapore and southern Peninsular Malaysia. The species underwent taxonomic revisions in 2019 and 2020, in which two former subspecies were elevated to separate species. As a result, the Raffles' banded langur meets the criteria for being listed as critically endangered by the IUCN. It is mainly threatened by habitat loss.
The red-finned blue-eye is a tiny, critically endangered species of fish in the family Pseudomugilidae. It is the only species in its genus. The species was first recorded in 1990. It is endemic to central Queensland in Australia, where it is restricted to springs in Bush Heritage's Edgbaston Reserve.
Protea comptonii, also known as saddleback sugarbush, is a smallish tree of the genus Protea in the family Proteaceae. It is found in South Africa and Eswatini.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Hawane Nature Reserve was first established in 1978 to protect an area of marsh along the Mbuluzi River in Eswatini. This area included the natural habitat of Kniphofia umbrina, a rare Eswatini endemic red hot poker. When the Hawane dam was built in 1988 to provide Mbabane's water supply, the reserve was expanded to protect the surrounding wetlands. The reserve is managed by the Swaziland National Trust Commission.
Consolea corallicola is a species of cactus known by the common names Florida semaphore cactus and semaphore pricklypear. It is endemic to Florida in the United States, where it is limited to the Florida Keys.
Veronica turrilliana is a species of speedwell in the family Plantaginaceae, endemic to the Strandzha mountain range in south-eastern Bulgaria and north-western Turkey. It is included in the Red Book of Bulgaria as an endangered species. and is categorized as data deficient by the International Union for Conservation of Nature (IUCN). It was described in 1923 by the Bulgarian botanists Nikolai Stojanov and Boris Stefanoff.
