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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
Iroko is a large hardwood tree from the west coast of tropical Africa that can live up to 500 years. This is the common name for the genus Milicia, in which there are two recognized species, which are closely related: Milicia excelsa and Milicia regia.
Hesperocyparis arizonica, the Arizona cypress, is a North American species of tree in the cypress family Cupressaceae, native to the southwestern United States and Mexico. Populations may be scattered rather than in large, dense stands.
Hesperocyparis bakeri, previously known Cupressus bakeri, with the common names Baker cypress, Modoc cypress, or Siskiyou cypress, is a rare species of western cypress tree endemic to a small area across far northern California and extreme southwestern Oregon, in the western United States.
Hesperocyparis goveniana commonly known as Californian cypress and Gowen cypress, is a species of western cypress that is endemic to a small area of coastal California near Monterey. It was formerly classified as Cupressus goveniana.
Chrysobalanaceae is a family of flowering plants, consisting of trees and shrubs in 27 genera and about 700 species of pantropical distribution with a centre of diversity in the Amazon. Some of the species contain silica in their bodies for rigidity and so the mesophyll often has sclerenchymatous idioblasts. The widespread species Chrysobalanus icaco produces a plum-like fruit and the plant is commonly known as the coco plum.
Corypha umbraculifera, the talipot palm, is a species of palm native to eastern and southern India and Sri Lanka. It is also grown in Cambodia, Myanmar, Thailand, Mauritius and the Andaman Islands. It is one of the five accepted species in the genus Corypha. It is a flowering plant with the largest inflorescence in the world. It lives up to 60 years before bearing flowers and fruits. It dies shortly after.
Phyla nodiflora, commonly known as Lippia, Kurapia, and Frogfruit, is a species of flowering plant in the family Verbenaceae. It can be found in the Tropics around the globe. It is often grown as an ornamental plant for ground cover, and is often present in yards or disturbed areas.
Kayea macrophylla is a species of flowering plant in the family Calophyllaceae. It is found in West Papua (Indonesia) and Papua New Guinea.
Tectiphiala ferox, or palmiste bouglé, is a species of flowering plant in the family Arecaceae. It is endemic to Mauritius.
Aloe squarrosa is a species of flowering plant in the Asphodelaceae family. It is from the island of Socotra, Yemen.
Licania is a genus of over 100 species of trees and shrubs in the family Chrysobalanaceae. Species are found naturally occurring in neotropical forests from southern Mexico to Brazil and the Lesser Antilles. Due to increased deforestation and loss of habitat, several species have declined, some markedly so, and L. caldasiana from Colombia appears to have gone extinct in recent years. Many species are either rare or restricted in distribution and therefore potentially threatened with future extinction. In 2016, a new circumscription of Licania was outlined, with over 100 species being placed in other genera such as Moquilea, Leptobalanus, Hymenopus, Microdesmia, Parinariopsis, Geobalanus and Cordillera.
Oxanthera brevipes is a species of plant in the family Rutaceae. It is endemic to New Caledonia. It was proposed as a novel species by Benjamin C. Stone based on two specimens, distinguished from other false oranges by a non-articulated petiole. The genus Oxanthera has been synonymized with Citrus, but a name in Citrus does not appear to have been published, and Plants of the World Online regards "Oxanthera brevipes" as an unplaced name.
Prunus arborea is a species of plant in the family Rosaceae. It is found in Indonesia, Malaysia, Singapore, and Thailand.
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, invasive species, and climate change. 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.
Hesperocyparis stephensonii is a species of western cypress known as the Cuyamaca cypress that is found only in one very small area in Southern California.
Hesperocyparis glabra, known as the Arizona smooth bark cypress or smooth Arizona cypress, is a conifer native to the American Southwest, with a range stretching over the canyons and slopes in a somewhat wide vicinity around Sedona, Arizona. It is distinguished from Hesperocyparis arizonica by its very smooth, non-furrowed bark which can appear in shades of pink, cherry, and grey.
Flacourtia indica, is a species of flowering plant native to much of Africa and tropical and temperate parts of Asia. It has various uses, including folk medicine, fuel, animal food and human food.
Iroko is a large hardwood tree from the west coast of tropical Africa that can live up to 500 years. This is the common name for the genus Milicia, in which there are two recognized species, which are closely related: Milicia excelsa and Milicia regia.
