Conservation status

the risk of extinction
The conservation status of a species is an indicator of the likelihood of that species continuing to survive. ...

Extinction

Extinct
The Dodo, shown here in illustration, is an often-cited[1] example of extinction. ...

Threatened

Critically Endangered
Endangered
Vulnerable
An endangered species is a species whose population is so small that it is in danger of becoming extinct. ... The endangered Sea Otter An endangered species is a population of organisms (usually a taxonomic species), which because it is either (a) few in number or (b) threatened by changing environmental or predation parameters, it is at risk of becoming extinct. ... Species that are vulnerable are threatened but their chances of extinction are lower that endangered or critically endangered. ...

IUCN Red List
The World Conservation Union or International Union for Conservation of Nature and Natural Resources (IUCN) is an international organization dedicated to natural resource conservation. ... The IUCN Red List of Threatened Species (also known as the IUCN Red List and Red Data List), created in 1963, is the worlds most comprehensive inventory of the global conservation status of plant and animal species. ...

Conservation Dependent (LR/cd) was an IUCN category assigned to species or lower taxa which were dependent on conservation efforts to prevent the taxon becoming threatened with extinction. Such taxa must be the focus of a continuing taxon-specific or habitat-specific conservation programme targeted towards the taxon in question, the cessation of which would result in the taxon qualifying for one of the threatened categories within a period of five years. Threatened species refers to animal and plant species under a serious, but perhaps not imminent, threat of extinction. ... Threatened species refers to animal and plant species under a serious, but perhaps not imminent, threat of extinction. ...


The category is part of the IUCN 1994 Categories & Criteria (version 2.3), which is no longer used in evaluation of taxa, but persists in the IUCN Red List for taxa evaluated prior to 2001, when version 3.1 was first used. Although using the 2001 (v3.1) system these taxa are classed as Near Threatened, but those that have not been re-evaluted Remain with the "Conservation Dependent" category. The IUCN Red List of Threatened Species (also known as the IUCN Red List and Red Data List), created in 1963, is the worlds most comprehensive inventory of the global conservation status of plant and animal species. ...


Examples of Conservation Dependent species include the Pyrenean Chamois, Leopard Shark, Black Caiman and Bristlecone Fir. Binomial name Rupicapra pyrenaica (Bonaparte, 1845) The Pyrenean Chamois, (French: Izard or Isard, Spanish Rebeco or Sarrio, Catalan: Isard ) Rupicapra pyrenaica pyrenaica is a Goat antelope that lives in the Pyrenees, Cantabrian Mountains and Apennine Mountains. ... Binomial name Triakis semifasciata Girard, 1855 The leopard shark, Triakis semifasciata, is a hound shark found in the coastal waters of the eastern Pacific Ocean, along the coast of North America from Oregon to Baja California. ... Binomial name Melanosuchus niger Spix, 1825 The Black Caiman (Melanosuchus niger) is an endangered species, related to alligators. ... Binomial name Abies bracteata (D. Don) A. Poit. ...


There are 402 taxa (148 animals and 254 plants) in the 2006 IUCN Red List still classified as Conservation Dependent, all last evaluated in 2000 or prior. The animal taxa are made up of 110 species, 33 subspecies (all mammals), 4 species populations, 1 subspecies stock (Blue Whale North Pacific stock[1]), and the plant taxa are made up of 238 plant species, 10 subspecies, and 6 varieties. The IUCN Red List of Threatened Species (also known as the IUCN Red List and Red Data List), created in 1963, is the worlds most comprehensive inventory of the global conservation status of plant and animal species. ... Binomial name Balaenoptera musculus (Linneus, 1758) Blue Whale range The Blue Whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales. ...


Excluding subspecies and subpopulations, there are 63 mammals, 14 gastropods, 12 ray-finned fish, 9 crustaceans, 5 bivalves, 3 reptiles, 3 insects, and 1 shark with this classification. 59 species are listed as being terrestrial, 25 freshwater, 19 marine, and 7 both terrestrial and freshwater. This last group (terrestrial & freshwater) includes crocodile, turtle, and antelope[2] species. Orders Multituberculata (extinct) Palaeoryctoides (extinct) Triconodonta (extinct) Subclass Australosphenida Ausktribosphenida Monotremata Subclass Eutheria (excludes extinct ancestors) Afrosoricida Anagaloidea (extinct) Arctostylopida (extinct) Artiodactyla Carnivora Cetacea Chiroptera Cimolesta (extinct) Cingulata Creodonta (extinct) Condylarthra (extinct) Dermoptera Desmostylia (extinct) Dinocerata (extinct) Embrithopoda (extinct) Hyracoidea Insectivora Lagomorpha Leptictida (extinct) Litopterna (extinct) Macroscelidea Mesonychia (extinct) Notoungulata... Subclasses Eogastropoda (True Limpets and relatives) Orthogastropoda The gastropods, gasteropods, or univalves, are the largest and most successful class of mollusks, with 60,000-75,000 known living species comprising the snails and slugs as well as a vast number of marine and freshwater species. ... Orders See text The Actinopterygii are the ray-finned fish. ... Classes Remipedia Cephalocarida Branchiopoda Ostracoda Maxillopoda Malacostraca The crustaceans (Crustacea) are a large group of arthropods (55,000 species), usually treated as a subphylum. ... Orders Subclass Protobranchia Solemyoida Nuculoida Subclass Pteriomorphia - oysters, mussels Arcoida Mytiloida Pterioida Subclass Paleoheterodonta Trigoinoida Unionoida - freshwater mussels Subclass Heterodonta - clams, zebra mussels Veneroida Myoida Subclass Anomalosdesmata Pholadomyoida Bivalves are molluscs belonging to the class Bivalvia. ... Classes & Orders See taxonomy Insects are invertebrate animals of the Class Insecta, the largest and (on land) most widely-distributed taxon within the phylum Arthropoda. ...

The largest class of plants with this status is Magnoliopsida (196 species, 7 subspecies, 3 varieties), followed by Conifers (25 sp, 3 ssp, 1 var), and Liliopsida (17 sp, 2 var), which together make up all 254 Conservation Dependent plant taxa. Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. ... Magnoliopsida is the botanical name for a class: this name is formed by replacing the termination -aceae in the name Magnoliaceae by the termination -opsida (Art 16 of the ICBN). ... Liliopsida is the botanical name for a class. ...


In this category, only mammal taxa have population trends which are evaluated and known. The Southern Right Whale is the only Conservation Dependent species evaluated with an increasing population. Additionally, 14 species have a stable population, and 19 are decreasing. The remaining species have unknown or unevaluted trends. Of the mammal subspecies with evaluted and known trends: 2 increasing, 10 stable, and 9 decreasing. The two shark taxa are the only non-mammals with an evaluted trend, however the result is merely "uncertain or unknown".
