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 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.
The Eurasian brown bear is one of the most common subspecies of the brown bear, and is found in much of Eurasia. It is also called the European brown bear, common brown bear, common bear, and colloquially by many other names. The genetic diversity of present-day brown bears has been extensively studied over the years and appears to be geographically structured into five main clades based upon analysis of the mtDNA.
Schoepfia is a genus of small hemiparasitic trees, flowering plants belonging to the family Schoepfiaceae. The genus has long been placed in the Olacaceae family.
Translocation in wildlife conservation is the capture, transport and release or introduction of species, habitats or other ecological material from one location to another. It contrasts with reintroduction, a term which is generally used to denote the introduction into the wild of species from captive stock. The International Union for the Conservation of Nature (IUCN) catalogues translocation projects for threatened species around the globe.
Aspidosperma megalocarpon is a species of plant in the family Apocynaceae. It can be found in Belize, Colombia, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Suriname, Venezuela, and NW Brazil.
Myrcia acutissima is a species of plant in the family Myrtaceae. It is endemic to Jamaica.
Myrcia nodosa is a species of plant in the family Myrtaceae. It is endemic to Jamaica.
Myrcia umbelliformis is a species of plant in the family Myrtaceae. It is endemic to Jamaica.
Rothmannia annae is a species of plant in the family Rubiaceae. It is endemic to the Seychelles. It is found in its natural state only on Aride Island, where its habitat is protected by Island Conservation Society.
Schoepfia harrisii is a species of flowering plant in the Schoepfiaceae family. It is a small tree or shrub, growing two to five metres tall. It is endemic to Jamaica, where it is only known to occur in the parishes of Trelawny and Clarendon, in what is known as Cockpit Country, a region of many steep, rounded, limestone hills, shaped like an egg-carton. Here it grows on crags in moist woodland, between 600 and 900m in elevation.
A Regional Red List is a report of the threatened status of species within a certain country or region. It is based on the IUCN Red List of Threatened Species, an inventory of the conservation status of species on a global scale. Regional Red Lists assess the risk of extinction to species within a political management unit and therefore may feed directly into national and regional planning. This project is coordinated by the Zoological Society of London, the World Conservation Union (IUCN) and partners in national governments, universities and organizations throughout the world.
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 and invasive species. 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.
A not evaluated (NE) species is one which has been categorized under the IUCN Red List of threatened species as not yet having been assessed by the International Union for Conservation of Nature.
Julbernardia seretii, commonly known as the Congo zebrawood, is a species of legume in the family Fabaceae. It is found in tropical West and Central Africa.
Loewia is a genus of flowering plants from East Kenya, Ethiopia and Somalia, belonging to the family Passifloraceae.
Streptopetalum arenarium is a subshrub native to Somalia, Africa. It is distylous, grows up to 0.5 meters tall, has elliptic to ovate leaves, and racemes flowers. It was originally described by Mats Thulin.
Streptopetalum hildebrandtii is a perennial herb native to the grasslands of Kenya and Tanzania, Africa. It is found at altitudes of 1000-1250m.
