|Risk of extinction|
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. The conservation status of a Species is an indicator of the likelihood of that species remaining extant either in the present day or the near future In Biology and Ecology, extinction is the cessation of existence of a Species or group of taxa. Extinct in the Wild ( EW) is a Conservation status assigned to species or lower taxa the only known living members of which are being kept in captivity or as a naturalized Organisms with a conservation status of critically endangered have an extremely high risk of becoming extinct An endangered species is a population of an organism which is at risk of becoming Extinct because it is either few in numbers or threatened by changing environmental or predation A vulnerable species is a Species which is likely to become endangered unless the circumstances threatening its survival and reproduction improve Threatened species are any species (including Animals Plants fungi, etc Near Threatened ( NT) is a Conservation status assigned to species or lower taxa which may be considered threatened with extinction in the near future although Least Concern ( LC) is an IUCN category assigned to extant species or lower taxa which have been evaluated but do not qualify for any other category The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List) created in 1963 is the world's most comprehensive inventory of the global The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List) created in 1963 is the world's most comprehensive inventory of the global Threatened species are any species (including Animals Plants fungi, etc Such taxa must be the focus of a continuing taxon-specific or habitat-specific conservation program 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 are any species (including Animals Plants fungi, etc
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. The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List) created in 1963 is the world's most comprehensive inventory of the global 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-evaluated Remain with the "Conservation Dependent" category. Near Threatened ( NT) is a Conservation status assigned to species or lower taxa which may be considered threatened with extinction in the near future although
Examples of Conservation Dependent species include the Pyrenean Chamois, Leopard Shark, Black Caiman and Bristlecone Fir. The Pyrenean Chamois, ( French: izard or isard, Spanish: rebeco or gamuza, Aragonese: sarrio or The leopard shark, Triakis semifasciata, is a Hound shark found in the coastal waters of the eastern Pacific Ocean, along the coast The black caiman (Melanosuchus niger is a crocodilian It is a Carnivorous Reptile that lives along slow-moving Rivers and Lakes The Bristlecone Fir or Santa Lucia Fir ( Abies bracteata) is a rare Fir, confined to slopes and the bottoms of rocky canyons in the Santa Lucia
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 IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List) created in 1963 is the world's most comprehensive inventory of the global The animal taxa are made up of 110 species, 33 subspecies (all mammals), 4 species populations, 1 subspecies stock (Blue Whale North Pacific stock), and the plant taxa are made up of 238 plant species, 10 subspecies, and 6 varieties. The Blue Whale ( Balaenoptera musculus) is a Marine mammal belonging to the suborder of Baleen whales (called Mysticeti
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. Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands The class Gastropoda or the gastropods, also previously known as gasteropods, or univalves, and more commonly known as Snails The Actinopterygii (the plural form of Actinopterygius) comprise the class of the ray-finned fishes. Structure of crustaceans As Arthropods crustaceans have a stiff Exoskeleton, which must be shed to allow the animal to grow ( Ecdysis or molting Bivalves are Molluscs belonging to the class Bivalvia. They have two-part shells and typically both valves are symmetrical along the hinge line Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Chondrichthyes or cartilaginous fishes are jawed Fish with paired fins paired nostrils scales two-chambered hearts and skeletons made of Cartilage rather 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 species. Antelope are Ruminant hoofed Mammals of the family Bovidae in the order of Even-toed ungulates.
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. A class is the Taxonomic rank in the Biological classification of organisms in Biology below phylum and above order. Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its Liliopsida is a Botanical name for the class containing the family Liliaceae (or Lily Family
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. The Southern Right Whale ( Eubalaena australis) is a Baleen whale, one of three species classified as Right whales belonging to the genus Eubalaena Additionally, 14 species have a stable population, and 19 are decreasing. The remaining species have unknown or unevaluated trends. Of the mammal subspecies with evaluated and known trends: 2 increasing, 10 stable, and 9 decreasing. The two shark taxa are the only non-mammals with an evaluated trend, however the result is merely "uncertain or unknown".
In Australia, the Environment Protection and Biodiversity Conservation Act 1999 still uses a "conservation dependent" category for classifying fauna and flora species. The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act is an Act of the Parliament of Australia that provides a framework for protection of the Species recognised as "conservation dependent" do not receive special protection, as they are not considered "matters of national environmental significance under the EPBC Act" .
The legislation uses categories similar to those of the IUCN 1994 Categories & Criteria. It does not, however, have a Near Threatened category, or any other "Lower Risk" categories. Near Threatened ( NT) is a Conservation status assigned to species or lower taxa which may be considered threatened with extinction in the near future although
As of December 2006, only two species have received the status under the act:
No flora has been given the category under the EPBC Act. The orange roughy, red roughy, or deep sea perch, Hoplostethus atlanticus, is a relatively large Deep-sea fish belonging to the Slimehead
