IUCN has a Red List which provides a systematic list of plants and animals into various categories. Structure of Categories.

      The Red List of Ecosystems criteria focus on four ecological symptoms to estimate the risk that an ecosystem type will lose its defining features (characteristic native biota and/or ecological processes; figure 1).These include two distributional symptoms: (A) ongoing declines in distribution, indicating ongoing incidence of threatening processes that result in . The IUCN Red List of Threatened Species, is the world's most comprehensive inventory of the global conservation status of plant and animal species. It uses a set of quantitative criteria to evaluate the extinction risk of species. These criteria .

      BirdLife International, as the IUCN Red List Authority for birds, continually collates up-to-date information on Globally Threatened Birds from the published literature and from a worldwide network of experts. This information is used to evaluate the status of each species for the IUCN Red List of Threatened Species TM.   These criteria are relevant to most 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. The IUCN Red List Categories: The IUCN Red List Categories define the extinction risk of species assessed. Nine categories extend from.
