Oxygyne triandra is a species of plant in the Burmanniaceae family. It is endemic to Cameroon. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
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 are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature (IUCN) as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status.
Themeda triandra is a species of C4 perennial tussock-forming grass widespread in Africa, Australia, Asia and the Pacific. In Australia it is commonly known as kangaroo grass and in East Africa and South Africa it is known as red grass and red oat grass or as rooigras in Afrikaans. Kangaroo grass was formerly thought to be one of two species, and was named Themeda australis.
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.
Areca triandra, the wild areca palm, is a palm which is often used as ornamental plant. It is native to India, Bangladesh, Cambodia, Laos, Burma, Thailand, Vietnam, Malaysia, Indonesia, and the Philippines. It is also reportedly naturalized in Panama and in southern China. As a wild plant, it commonly occurs in littoral forest in Southeast Asia.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.
The Canary long-eared bat, also known as the Canary big-eared bat or Tenerife long-eared bat, is a species of vesper bat endemic to the Canary Islands. According to the IUCN, it is vulnerable to the risk of extinction. The species is primarily found in woodland habitat at elevations between 100 and 2300 m. It feeds mainly on moths. Roosting sites include caves, lava tubes and abandoned buildings.
Rafetus is a genus of highly endangered softshell turtles in the family Trionychidae. It is a genus of large turtles which are found in freshwater habitats in Asia.
The Hainan partridge is a species of bird in the family Phasianidae. It is endemic to Hainan Island, China. Its natural habitats are primary evergreen forests. It is threatened by habitat loss and has been assessed as a vulnerable species.
Wallichia triandra is a species of flowering plant in the family Arecaceae that is native to South Tibet in China and also to the neighboring Arunachal Pradesh region of India.
The Somali hedgehog is a species of mammal in the family Erinaceidae. It is endemic to Somalia and Somaliland. The Somali hedgehog is nocturnal.
Day's shrew is a species of mammal in the family Soricidae. It is endemic to India. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The Sakeji horseshoe bat is a species of bat in the family Rhinolophidae. It is endemic to Zambia. Its natural habitats are subtropical and tropical dry and moist lowland forest, and moist savanna. It is threatened by habitat loss. It was discovered in 2000.
Horsfieldia triandra is a species of plant in the family Myristicaceae. It is a tree endemic to Sumatra.
Oxygyne is a genus of plant in family Burmanniaceae, first described as a genus in 1906. It has a highly disjunct distribution, found in Japan in East Asia and in Cameroon in Central Africa.
Wiesneria is a genus in the family Alismataceae. The plant usually lives in natural temporary water pools on lateritic plateaus. Wiesneria triandra was first described in the south of the Indian state of Maharashtra. They are well spread out over the regions they occupy and have no common uses, making them of least concern.
Salix triandra, with the common names almond willow, almond-leaved willow or black maul willow, is a species of willow native to Europe and Western and Central Asia. It is found from south-eastern England east to Lake Baikal, and south to Spain and the Mediterranean east to the Caucasus, and the Alborz Mountains. It usually grows in riparian habitats, on river and stream banks, and in wetlands.
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
