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 the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Cypress is a common name for various coniferous trees or shrubs of northern temperate regions that belong to the family Cupressaceae. The word cypress is derived from Old French cipres, which was imported from Latin cypressus, the latinisation of the Greek κυπάρισσος (kyparissos). Cypress trees are a large classification of conifers, encompassing the trees and shrubs from the cypress family (Cupressaceae) and many others with the word “cypress” in their common name. Many cypress trees have needle-like, evergreen foliage and acorn-like seed cones.
Threatened species are any species which are vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment.
The snowcocks or snowfowl are a group of bird species in the genus Tetraogallus of the pheasant family, Phasianidae. They are ground-nesting birds that breed in the mountain ranges of southern Eurasia from the Caucasus to the Himalayas and western China. Some of the species have been introduced into the United States. Snowcocks feed mainly on plant material.
Juniperus indica, the black juniper, is a juniper native to high-altitude climates in the Himalaya, occurring in Pakistan, India, Nepal, Bhutan and China.
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 exist and are in use at international, multi-country, national and local levels as well as for consumer use.
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or conservation dependent.
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.
Notiosorex cockrumi, also called Cockrum's gray shrew or Cockrum's desert shrew, is a tiny species of shrews named in 2003. This red-toothed shrew, which is as light as a penny, is the first new mammal species from Arizona since 1977. Its range extends from Arizona to central Sonora, Mexico.
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.
Bidens amplectens, the Waiʻanae kokoʻolau, is a species of flowering plant in the family Asteraceae. It belongs to the genus Bidens, collectively called kokoʻolau or koʻokoʻolau in the Hawaiian language. It is found in coastal and dry lowland habitats in the Waiʻanae Range on Oʻahu. It is threatened by habitat loss due to the spread of invasive weeds and brush fires. The species is also threatened by climate change and habitat degradation, and herbivory. Bidens amplectens is currently listed as endangered under the Endangered Species Act.
The red-vented barbet is an Asian barbet native to Laos, Vietnam and Cambodia, where it inhabits subtropical or tropical moist lowland forest and subtropical or tropical moist montane forests.
Campylospermum is a genus of plants in the family Ochnaceae.
Campylospermum scheffleri is a species of plant in the family Ochnaceae. It is native from south-east Kenya to Tanzania.
Campylospermum serratum is a plant in the family Ochnaceae. The specific epithet serratum is from the Latin meaning "with teeth", referring to the leaf margin. It is found in Tropical Asia, from Sulawesi, Indonesia to Hainan, Zhōngguó/China and over to southwester India. Gomphia serrata was a previous common name for the species. The plant is used for it wood and its sap is used in folk medicine and in the past for teeth-blackening.
Hopea odorata, or ta-khian, is a species of plant in the family Dipterocarpaceae. It is found in Bangladesh, Cambodia, India, Laos, Malaysia, Myanmar, Thailand, and Vietnam. It is a large tree reaching up to 45 m in height with the base of the trunk reaching a diameter of 4.5 m. It grows in forests, preferably near rivers, at altitudes between 0 and 600m. In places such as West Bengal and the Andaman Islands it is often planted as a shade tree. Valued for its wood, it is a threatened species in its natural habitat.
Ouratea is a genus of flowering plants in the family (Ochnaceae). Many genera have been brought into synonymy with Ouratea, including Gomphia.
Allium amplectens, the narrowleaf onion, is a species of onion plant. It is native to the West coast of the United States, in Oregon, Washington State and California, also British Columbia in Canada. It grows in woods and especially in clay and serpentine soils.
Lycopus amplectens, common names clasping-leaved water-horehound, sessile-leaved bugleweed, and sessile-leaved water-horehound, is a species of Lycopus native to North America.
Campylospermum oliveri is a species of plant in the Ochnaceae family. It is endemic to Cameroon. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
