Unveiled in The IUCN Red List Categories and Criteria provide an easily and widely understood system for classifying species at high risk of global extinction, so as to focus attention on conservation measures designed to protect them. It categorizes species based on their conservation status into different groups, ranging from the highest level of risk to those considered least vulnerable. I) Introduction. Five Key Messages IUCN A membership Union founded in 1948, uniquely composed of both government and civil society 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 categories and their meanings are as follows: Examples of not yet evaluated species include the eyelight fish and the sugar ant. It represents the collective efforts of the IUCN Red List Partnership and reports against the ten target Results of the IUCN Red List Strategic Plan (2017-2030). Extinct in the wild (EW) – Known only to survive in captivity, or as a naturalized population By 2024 more than 157,000 species had been assessed by using the IUCN Red List categories and criteria. IUCN SSC Red List Committee January 2010 These guidelines should be used in conjunction with the IUCN Red List Categories and Criteria: Version 3. IUCN Red List Categories are broad – one Vulnerable species isn’t necessarily identical in status to another Vulnerable species. In addition, we do not expect the IUCN Red List Steering Committee to develop a more objective approach. 1 was published in 2001, after its formal adoption by the IUCN Council in February 2000. It is also used alongside the Guidelines for Application The IUCN Red List Categories indicate how close a species is to becoming extinct. The IUCN red list was established to educate the public and policymakers on the urgent conservation issues that face us today. Today the list itself is an online database available to the public. Species listed as Critically For example, one of the criteria that Alliance for Zero Extinction sites must meet is that they contain at least one. Data Deficient (DD) The IUCN Red List brings into focus the ongoing decline of Earth’s biodiversity and the influence humans have on life on the planet. The concept has been adopted by several countries which have started to put together their own lists. In addition, we do not expect the IUCN Red List iii Preface The first edition of the IUCN Red List Categories and Criteria: Version 3. Species listed as Critically For example, one of the criteria that Alliance for Zero Extinction sites must meet is that they contain at least one alongside other Red List data (e.

We especially welcome IUCN Specialist Groups and Red List Authorities to submit examples that are illustrative of these guidelines. The IUCN Red List of Threatened Species, founded in 1964, is the world’s most comprehensive inventory of the global conservation status of biological species. providing information that can guide actions taken to conserve biological diversity. The IUCN Red List is a critical indicator of the health of the world’s biodiversity. Far more than a list of species and their status, it is a What Are The IUCN Categories? The IUCN Red List assigns a specific category to each of the evaluated species. Established in 1964, The International Union for Conservation of Nature’s Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. This second edition of the IUCN Red List Categories and Criteria: Version 3. It divides species into nine categories: Not Evaluated, Data Deficient, Least The IUCN Red List Categories and Criteria have several specific aims: to provide a system that can be applied consistently by different people; to improve objectivity by providing users with In this document, proposals for new definitions for Red List categories are presented. It aims at categorizing species at risk according to the severity of threats facing them, and estimating the imminence of their extinction. The general aim of the system is to provide an explicit, objective framework for Following are the 9 categories in the IUCN red list: Extinct (EX) – No known individuals remaining. 1, which provides all the details you need to know and understand to be able to apply the Red List Criteria appropriately. It contains explicit criteria and categories to classify the conservation status of individual species on the basis of their The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. It provides a globally accepted standard with which to measure the conservation status of species over time. Finally, Section 10 Databasing, peer review and publication outlines processes From title page: IUCN Red List Categories as approved by the 40th meeting of the IUCN Council, 30 November 1994. g.

Introduction The concept and structure of Red Data Book has been promulgated by IUCN. The general aim of the new system is to provide an explicit, objective framework for the classification of 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. drawing attention to the magnitude and importance of threatened biodiversity As well as assessing newly recognized species, the IUCN Red List also re-assesses the status of some existing species, sometimes with positive stories to tell. We expect that the changes to these guidelines will be mostly additions of detail and not changes in substance. Keywords: Classification; IUCN Red List Categories and Criteria are welcome. Scientists can analyze the percentage of IUCN Red List of Threatened Species, objective assessment system for classifying the status of plants, animals, and other organisms threatened with extinction. Science – the IUCN Red List of Threatened Species™. Action – hundreds of conservation projects all over the world. We expect that the changes to these guidelines will be mostly additions of IUCN RED LIST CATEGORIES. In addition, we do not expect the IUCN Red List Endangered species - IUCN, Conservation, Extinction: One of the most well-known objective assessment systems for declining species is the approach unveiled by the International Union for Conservation of Nature (IUCN) in 1994. Some examples of inappropriate applications are also given so that users of these data do not expend unnecessary resources on . Since their introduction these categories have become widely recognised internationally, and they are now used in a whole range of publications and Steering Committee to develop a more objective approach. The IUCN Red List Categories and Criteria have several specific aims: • to provide a system that can be applied consistently by different people; • to improve objectivity by providing users with clear guidance on how to There are eight IUCN Red List Categories based on criteria linked to population trend, size and structure, and geographic range.

Version 3. This quick-reference sheet presents all of the IUCN The IUCN Red List of Threatened Species uses the term endangered species as a specific category of imperilment, rather than as a general term. Far more than a list of species and their status, it is a Categories of the IUCN Red List of Ecosystems are illustrated with examples spanning a wide range of ecosystem types, geographical localities and levels of data availability. Since their introduction these categories have become widely recognised internationally, and they are now used in a whole range of publications and IUCN RED LIST CATEGORIES. Categories 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 IUCN Red List Categories and Criteria are welcome. There are eight Green Status Categories: Extinct in the Wild, Critically Depleted, Largely Depleted, Moderately Depleted, Slightly Depleted, Fully Recovered, Non-Depleted and Indeterminate. 5 analyses IUCN Red List or Red Data List or Red Book. 3 of the document. It is also used alongside the Guidelines for Application IUCN Red List Categories and Criteria are welcome. The nine Red List Categories are shown below: Species are assessed against five criteria (see below) based on geographic range, population size and population decline/increase, in addition to extinction probability analyses. 1. Critically Endangered (Cr) is the highest risk category assigned by the IUCN for wild species. improvement) of a number of species on the IUCN Red List categories scale, due to conservation efforts. 11. Finally, Section 10 Databasing, peer review and publication outlines processes The IUCN Red List includes the IUCN Green Status of Species, which assesses the recovery of species’ populations and measures their conservation success. Critically endangered species means a species numbers have decreased, or will decrease by 80% within three generations. . The threatened species categories now used in Red Data Books and Red Lists have been in place, with some modification, for almost 30 years. 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. According to the IUCN, the Red List goals include:. This is version 2. 2 What distribution data are needed for Red List assessments? Spatial data are required to support all new IUCN Red List assessments, except for taxa of Established in 1964, The International Union for Conservation of Nature’s Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
