This list is of Red Lists, Red Data Books, and related initiatives that assess and document the extinction risk of species, whether on an international or more local level (regional Red Lists). The IUCN has published a set of Guidelines for Application of the IUCN Red List Criteria at Regional and National Levels and at least 113 countries have ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
A Regional Red List may be created by any country or organisation by following the clear, repeatable protocol. The process is as follows: All information relevant to a species conservation status is collected, including species distribution, population trend information, habitat, ecology and life history information, threats to the species and conservation measures currently in place.
The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit; [17] nearly 2,000 species were added, [18] with 4 species to the extinct list, 2 to the rediscovered list. [19] The IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction.
Any extant taxa that cannot be found with the IUCN Red List can be considered NE within IUCN, and the status field should be left blank, unless they are found within another system (e.g. TNC Archived 2009-07-28 at the Wayback Machine, EPBC, ESA, UNEP-WCMC Archived 2011-04-12 at the Wayback Machine).
The Red List Index (sampled approach) (SRLI) has been developed in order to determine the threat status and also trends of lesser-known and less charismatic species groups. It is a collaboration between IUCN members and is coordinated through the Institute of Zoology (IoZ), the research division of the Zoological Society of London (ZSL).
The NatureServe conservation status system, maintained and presented by NatureServe in cooperation with the Natural Heritage Network, was developed in the United States in the 1980s by The Nature Conservancy (TNC) as a means for ranking or categorizing the relative imperilment of species of plants, animals, or other organisms, as well as natural ecological communities, on the global, national ...
The basis of the IUCN Red List of Ecosystems are the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing an ecosystem's risk of collapse. They are designed to be: broadly applicable across type ecosystems and geographic areas, transparent and ...
