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 are produced by countries and 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.
Chlorophytum comosum, usually called spider plant or common spider plant due to its spider-like look, also known as spider ivy, ribbon plant, and hen and chickens is a species of evergreen perennial flowering plant of the family Asparagaceae. It is native to tropical and Southern Africa but has become naturalized in other parts of the world, including Western Australia and Bangladesh. Chlorophytum comosum is easy to grow as a houseplant because of its resilience, but it can be sensitive to the fluoride in tap water, which commonly gives it "burnt tips". Variegated forms are the most popular.
Spider plant is a common name for several plants and may refer to:
Anthericum is a genus of about 65 species, rhizomatous perennial plants in the family Asparagaceae, subfamily Agavoideae. It was formerly placed in its own family, Anthericaceae. The species have rhizomatous or tuberous roots, long narrow leaves and branched stems carrying starry white flowers. The members of this genus occur mainly in the tropics and southern Africa and Madagascar, but are also represented in Europe.
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).
Chlorophytum, is a genus of almost 200 species of evergreen perennial flowering plants in the century plant subfamily within the asparagus family. The plants are native to the tropical and subtropical regions of Africa, Australia, and Asia.
Chlorophytum borivilianum is a herb with lanceolate leaves, from tropical wet forests in the peninsular Indian region. The Hindi name is safed musli.
On 29 January 2010, the IUCN Red List of Threatened Species identified 5220 endangered species, subspecies and varieties, stocks and sub-populations.
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.
Chlorophytum tuberosum is a species of flowering plant in the Asparagaceae family. It is one of several species known by the common name musli. It is native to parts of Africa and India. It has historical uses in Ayurveda.
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.
Terminalia ivorensis is a species of tree in the family Combretaceae, and is known by the common names of Ivory Coast almond, idigbo, black afara, framire and emeri.
On 29 January 2010, the IUCN Red List of Threatened Species identified 6,702 data deficient species.
Chlorophytum inornatum is a flowering plant species in the genus Chlorophytum. It is the type species of its genus. It is related to the commonly known houseplant Chlorophytum comosum also referred to as a "spider plant". 3-(4'-Methoxybenzyl)-7,8-methylenedioxy-chroman-4-one, a homoisoflavanone with antimycobacterial activity, can be isolated from C. inornatum.
Chlorophytum holstii is a flowering plant species in the genus Chlorophytum, endemic to Tanzania and Kenya.
Chlorophytum laxum is a flowering plant species in the genus Chlorophytum, widespread through tropical Africa, Asia, and Australia.
Hen and chicken is a common name for several unrelated groups of plants. The name refers to the tendency of certain of these species to reproduce vegetatively by means of plantlets. These tiny plants are produced by the mother plant, and take root on touching the ground.
