An endangered species is a species which has been categorized as very likely to become extinct. Endangered ( EN ), as categorized by the International Union for Conservation of Nature ( IUCN ) Red List, is the second most severe conservation status for wild populations in the IUCN 's schema after Critically Endangered ( CR ). In 2012, the IUCN Red List featured 3079 animal and 2655 plant species as endangered ( EN ) worldwide. The figures for 1998 were, respectively, 1102 and 1197. Many nations have laws that protect conservation - reliant species : for example, forbidding hunting, restricting land development or creating preserves. Population numbers, trends and species ' conservation status can be found in the lists of organisms by population.

Many factors are considered when assessing the conservation status of a species ; e.g., such statistics as the number remaining, the overall increase or decrease in the population over time, breeding success rates, or known threats. The IUCN Red List of Threatened Species is the best - known worldwide conservation status listing and ranking system. Over 50 % of the world 's species are estimated to be at risk of extinction. Internationally, 199 countries have signed an accord to create Biodiversity Action Plans that will protect endangered and other threatened species. In the United States, such plans are usually called Species Recovery Plans. IUCN Red List The Siberian tiger is an Endangered ( EN ) tiger subspecies. Three tiger subspecies are already extinct ( see List of carnivorans by population ). Blue - throated macaw, an endangered species Brown spider monkey, an endangered species Siamese crocodile, an endangered species American burying beetle, an endangered species Kemp 's ridley sea turtle, an endangered species Mexican Wolf, the most endangered subspecies of the North American Grey Wolf. Approximately 143 are living wild. Though labelled a list, the IUCN Red List is a system of assessing the global conservation status of species that includes `` Data Deficient '' ( DD ) species -- species for which more data and assessment is required before their status may be determined -- as well species comprehensively assessed by the IUCN 's species assessment process. Those species of `` Near Threatened '' ( NT ) and `` Least Concern '' ( LC ) status have been assessed and found to have relatively robust and healthy populations, though these may be in decline. Unlike their more general use elsewhere, the List uses the terms `` endangered species '' and `` threatened species '' with particular meanings : `` Endangered '' ( EN ) species lie between `` Vulnerable '' ( VU ) and `` Critically Endangered '' ( CR ) species, while `` Threatened '' species are those species determined to be Vulnerable, Endangered or Critically Endangered. The IUCN categories, with examples of animals classified by them, include : Extinct ( EX ) no remaining individuals of the species Examples : aurochs ara atwoodi blackfin cisco Caribbean monk seal wooly mammoth Caspian tiger dodo Paraceratherium eastern cougar great auk Guam flycatcher Gomphotaria pugnax Javan tiger Labrador duck lesser bilby New Zealand quail passenger pigeon Schomburgk 's deer Steller 's sea cow thylacine toolache wallaby California Grizzly Bear Extinct in the wild ( EW ) Captive individuals survive, but there is no free - living, natural population.

Endangered species in the United States There is data from the United States that shows a correlation between human populations and threatened and endangered species. Using species data from the Database on the Economics and Management of Endangered Species ( DEMES ) database and the period that the Endangered Species Act ( ESA ) has been in existence, 1970 to 1997, a table was created that suggests a positive relationship between human activity and species endangerment. Endangered species Act `` Endangered '' in relation to `` threatened '' under the ESA. Under the Endangered Species Act of 1973 in the United States, species may be listed as `` endangered '' or `` threatened ''. The Salt Creek tiger beetle ( Cicindela nevadica lincolniana ) is an example of an endangered subspecies protected under the ESA. The US Fish and Wildlife Service as well as the National Marine Fisheries Service are held responsible for classifying and protecting endangered species, and adding a particular species to the list can be a long, controversial process ( Wilcove & Master, 2008, p. 414 ). Some endangered species laws are controversial. Typical areas of controversy include : criteria for placing a species on the endangered species list and criteria for removing a species from the list once its population has recovered ; whether restrictions on land development constitute a `` taking '' of land by the government ; the related question of whether private landowners should be compensated for the loss of uses of their lands ; and obtaining reasonable exceptions to protection laws. Also lobbying from hunters and various industries like the petroleum industry, construction industry, and logging, has been an obstacle in establishing endangered species laws. The Bush administration lifted a policy that required federal officials to consult a wildlife expert before taking actions that could damage endangered species. Under the Obama administration, this policy has been reinstated. Being listed as an endangered species can have negative effect since it could make a species more desirable for collectors and poachers. This effect is potentially reducible, such as in China where commercially farmed turtles may be reducing some of the pressure to poach endangered species. Another problem with the listing species is its effect of inciting the use of the `` shoot, shovel, and shut - up '' method of clearing endangered species from an area of land. Some landowners currently may perceive a diminution in value for their land after finding an endangered animal on it. They have allegedly opted to silently kill and bury the animals or destroy habitat, thus removing the problem from their land, but at the same time further reducing the population of an endangered species. The effectiveness of the Endangered Species Act -- which coined the term `` endangered species '' -- has been questioned by business advocacy groups and their publications but is nevertheless widely recognized by wildlife scientists who work with the species as an effective recovery tool. Nineteen species have been delisted and recovered and 93 % of listed species in the northeastern United States have a recovering or stable population. Currently, 1,556 known species in the world have been identified as near extinction or endangered and are under protection by government law. This approximation, however, does not take into consideration the number of species threatened with endangerment that are not included under the protection of such laws as the Endangered Species Act. According to NatureServe 's global conservation status, approximately thirteen percent of vertebrates ( excluding marine fish ), seventeen percent of vascular plants, and six to eighteen percent of fungi are considered imperiled. Thus, in total, between seven and eighteen percent of the United States ' known animals, fungi and plants are near extinction. This total is substantially more than the number of species protected in the United States under the Endangered Species Act. Bald eagle American bison Ever since mankind began hunting to preserve itself, over-hunting and fishing has been a large and dangerous problem. Of all the species who became extinct due to interference from mankind, the dodo, passenger pigeon, great auk, Tasmanian tiger and Steller 's sea cow are some of the more well known examples ; with the bald eagle, grizzly bear, American bison, Eastern timber wolf and sea turtle having been hunted to near - extinction. Many began as food sources seen as necessary for survival but became the target of sport. However, due to major efforts to prevent extinction, the bald eagle, or Haliaeetus leucocephalus is now under the category of Least Concern on the red list. A present - day example of the over-hunting of a species can be seen in the oceans as populations of certain whales have been greatly reduced. Large whales like the blue whale, bowhead whale, finback whale, gray whale, sperm whale and humpback whale are some of the eight whales which are currently still included on the Endangered Species List. Actions have been taken to attempt reduction in whaling and increase population sizes, including prohibiting all whaling in United States waters, the formation of the CITES treaty which protects all whales, along with the formation of the International Whaling Commission ( IWC ). But even though all of these movements have been put in place, countries such as Japan continue to hunt and harvest whales under the claim of `` scientific purposes ''. Over-hunting, climatic change and habitat loss leads in landing species in endangered species list and could mean that extinction rates could increase to a large extent in the future. Invasive species Main article : Introduced species The introduction of non-indigenous species to an area can disrupt the ecosystem to such an extent that native species become endangered. Such introductions may be termed alien or invasive species. In some cases the invasive species compete with the native species for food or prey on the natives. In other cases a stable ecological balance may be upset by predation or other causes leading to unexpected species decline. New species may also carry diseases to which the native species have no resistance. Conservation The dhole, Asia 's most endangered top predator, is on the edge of extinction. Captive breeding Main article : Captive breeding Captive breeding is the process of breeding rare or endangered species in human controlled environments with restricted settings, such as wildlife reserves, zoos and other conservation facilities. Captive breeding is meant to save species from extinction and so stabilize the population of the species that it will not disappear. This technique has worked for many species for some time, with probably the oldest known such instances of captive mating being attributed to menageries of European and Asian rulers, an example being the Père David 's deer. However, captive breeding techniques are usually difficult to implement for such highly mobile species as some migratory birds ( e.g. cranes ) and fishes ( e.g. hilsa ). Additionally, if the captive breeding population is too small, then inbreeding may occur due to a reduced gene pool and reduce immunity. In 1981, the Association of Zoos and Aquariums ( AZA ) created a Species Survival Plan ( SSP ) in order to help preserve specific endangered and threatened species through captive breeding. With over 450 SSP Plans, there are a number of endangered species that are covered by the AZA with plans to cover population management goals and recommendations for breeding for a diverse and healthy population, created by Taxon Advisory Groups. These programs are commonly created as a last resort effort. SSP Programs regularly participate in species recovery, veterinary care for wildlife disease outbreaks, and a number of other wildlife conservation efforts. The AZA 's Species Survival Plan also has breeding and transfer programs, both within and outside of AZA - certified zoos and aquariums. Some animals that are part of SSP programs are giant pandas, lowland gorillas, and California condors. Private farming Black rhino Southern bluefin tuna Whereas poaching substantially reduces endangered animal populations, legal, for - profit, private farming does the opposite. It has substantially increased the populations of the southern black rhinoceros and southern white rhinoceros. Dr Richard Emslie, a scientific officer at the IUCN, said of such programs, `` Effective law enforcement has become much easier now that the animals are largely privately owned... We have been able to bring local communities into the conservation programmes. There are increasingly strong economic incentives attached to looking after rhinos rather than simply poaching : from Eco-tourism or selling them on for a profit. So many owners are keeping them secure. The private sector has been key to helping our work. '' Conservation experts view the effect of China 's turtle farming on the wild turtle populations of China and South - Eastern Asia -- many of which are endangered -- as `` poorly understood ''. Although they commend the gradual replacement of turtles caught wild with farm - raised turtles in the marketplace -- the percentage of farm - raised individuals in the `` visible '' trade grew from around 30 % in 2000 to around 70 % in 2007 -- they worry that many wild animals are caught to provide farmers with breeding stock. The conservation expert Peter Paul van Dijk noted that turtle farmers often believe that animals caught wild are superior breeding stock. Turtle farmers may, therefore, seek and catch the last remaining wild specimens of some endangered turtle species. In 2009, researchers in Australia managed to coax southern bluefin tuna to breed in landlocked tanks, raising the possibility that fish farming may be able to save the species from overfishing.

Question: when is a species considered to be endangered
Answer: categorized as very likely to become extinct
