The IUCN Red List Categories and Criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction. It divides species into nine categories: Not Evaluated, Data Deficient, Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild and Extinct The Red Data Book categories provide an easily and widely understood method for highlighting those species under higher extinction risk, so as to focus attention on conservation measures designed to protect them. This document, incorporating changes recommended by IUCN members, was adopted by the IUCN Council in 1994 1. The IUCN Red List Categories and Criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction. The general aim of the system is to provide an explicit, objective framework for the classification of the broadest range of species according to their extinction risk. However, while the Red List may focus attention on those taxa at the highes
1994 IUCN Red List categories (version 2.3), used for species which have not been reassessed since 2001. In 1997, the IUCN Red List received criticism on the grounds of secrecy (or at least poor documentation) surrounding the sources of its data. These allegations have led to efforts by the IUCN to improve its documentation and data quality, and to include peer reviews of taxa on the Red List. What Are The IUCN Categories? The IUCN Red List assigns a specific category to each of the evaluated species. The categories and their meanings are as follows: Not Evaluated (NE) Several species are categorized as Not Evaluated. This categorization means that the IUCN and its specialists have not yet researched the species and its risk of extinction. Examples of not yet evaluated species include the eyelight fish and the sugar ant The IUCN Red List Categories The IUCN Red List Categories define the extinction risk of species assessed. Nine categories extend from NE (Not Evaluated) to EX (Extinct). What does IUCN mean by threatened

The IUCN Red List of Ecosystems Categories and Criteria is a global standard for how we assess the status of ecosystems, applicable at local, national, regional and global levels. Assessments determine whether an ecosystem is not facing imminent risk of collapse, or whether it is vulnerable, endangered, or critically endangered. This will be measured by assessing losses in area, degradation or. Over the last decade, the IUCN Red List Categories and Criteria have been used to assess an increasingly diverse range of taxa occurring in a wide variety of habitats.

The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). The 1994 IUCN Categories and Criteria were developed to improve objectivity and transparency in assessing the conservation status of species, and therefore to improve consistency and understanding among users. The 199 the rigorous IUCN Red List Categories and Criteria, ensuring the highest standards of scientific documentation, information management, expert review, and justification.
