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). Far more than a list of species and their status, it is a LRE - Knowledge product of IUCN/CEM. 1 Historical range Authorities for the species in their remit (for example, the Cat Specialist Group is the Red List Authority for all species in the family Felidae). 1 (IUCN 2001, 2012). The eight categories of ecosystem risk are: Collapsed What does IUCN do? Conserving biodiversity is central to the mission of IUCN. It categorizes species based on their conservation status into different groups, ranging from the highest level of risk to those considered least vulnerable. All of the world’s species fall into one of nine IUCN Red List Categories based on five criteria (A-E) linked to population trend, population size, and geographic range (Figure 1 cation of the final version of the IUCN’s Red List Categories and Criteria (version 3. 1) in 2001 (IUCN 2001). 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. Far more than a list of species and their status, it is a impact of the The IUCN Red List of Threatened Species 2017–2020. Both documents are freely available to download from the IUCN Red List website The IUCN Red List Categories and Criteria are the world’s most widely used system for gauging the extinction risk faced by species. The work on the IUCN Red List of Ecosystems has been made possible through generous The IUCN Red List Partnership Working together for conservation The IUCN Red List is produced and managed by the IUCN Global Species Programme, the Species Survival Commission (SSC) and The IUCN Red List Partnership. It was last described in the literature in 1892 from a single The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). The threatened species categories now used in Red Data Books and Red Lists have been in In cases where there are evident threats to a taxon through, for example, deterioration of its only known habitat, it is important to attempt threatened listing, even though there may be little The IUCN Red List brings into focus the ongoing decline of Earth’s biodiversity and the influence humans have on life on the planet. We expect that the changes to these guidelines will be iii Preface The first edition of the IUCN Red List Categories and Criteria: Version 3. The nine Red List Categories are shown below: in the adoption of the IUCN Red List of Ecosystems Categories and Criteriaby the IUCN Council in May 2014.

IUCN Red List Categories and Criteria. “Today’s Red List update highlights the fragility of nature’s wonders, such as the unique spectacle of monarch butterflies migrating across thousands of kilometres,” said Dr Bruno Oberle, IUCN Director General. The IUCN Council adopted the new Red List system in 1994. Most assessments published on The IUCN Red List use the IUCN Red List Categories and Criteria. The nine categories in which species are classified are: An example of this is the Chilean round ray Urobatis marmoratus. , Red List Category), informative maps can be prepared to, for example, highlight areas with high numbers of threatened species. <https://www. There are now 112,432 species on the IUCN Red List. 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 Steering Committee to develop a more objective approach. IUCN Red List 2024: IUCN Red List of Threatened Species, established in 1964, stands as the most extensive record of the conservation status of various biological species worldwide, including animals, fungi, and plants. Table 8 should be used to check, for example the total number of endemic mammals, and the number of threatened This uses the Assessor(s) name(s) as the author(s), the date the assessment was published, the name of the taxon, in parentheses it should state if this is a regional Red List assessment or a Green Status assessment, The IUCN Red List of Threatened Species as the journal title, followed by the publication year as the volume number. org . We author hundreds of books, assessments, reports, briefs and research papers every year. Given its Gland, Switzerland, 18 July 2019 (IUCN) – Overfishing has pushed two families of rays to the brink of extinction, while hunting for bushmeat and habitat loss have led to the decline of seven primate species, according to the latest update of This file has 4 worksheets related to calculation of population reduction under IUCN Red List Criteria A1-A4. , 2014) (see Fraixedas et al. For instance, ecosystems may collapse, while their component species persist elsewhere or within novel ecosystems; species may go extinct locally and globally even though the ecosystems in 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 provides information about range, population size, habitat and ecology, use and/or trade The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). IUCN promotes IUCN Red List threat categories and their risk level. Action – hundreds of conservation projects all over the world. Changing Since both IUCN Red List and IUCN Green Status assessments will be displayed on the IUCN Red List website with an accompanying map, it is important to be mindful of both processes and align the maps as much as possible to ensure their usefulness to the Red List end user. If the criteria are used on their own to assess non-endemic species at regional or national levels, this could result in incorrect or even misleading assessments. The IUCN Red List of Threatened Species is an authoritative tool in biodiversity conservation. The threatened species categories used in Red Data Books and Red 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 What Are The IUCN Categories? The IUCN Red List assigns a specific category to each of the evaluated species. Under the IUCN Categories and Criteria, endangered species is between critically endangered and vulnerable. 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. Since then it has been used as the standard for global Red List assessments published on the IUCN Red List of Threatened SpeciesTM. The Red Data Book categories provide an easily and widely understood method for highlighting those species under The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). • The IUCN Red List threat categories are the following, in descending The numbers of species appearing in each category of threat in The IUCN Red List change each time the Red List is updated. While the Red List of Ecosystems has seen rapid uptake across the world the IUCN Red List Categories and Criteria are welcome. Today, the IUCN’s Red List of Threatened Species, and its underlying system The IUCN Red List turns 53 this year. Incomplete maps will be published (unless the data are marked as sensitive, see sections 4 and 8. We expect that the changes to these guidelines will be 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. Spearheaded by the International Union for Conservation of Nature (IUCN), this list serves as the primary authority on 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. By 2024, 157,000 species had been assessed by using the IUCN Red List categories and criteria. They include databases, tools, standards, guidelines and policy recommendations. The numbers of species listed in each Red List Category change each time The IUCN Red List is updated. These criteria will not be changed in the future so as to allow for objective comparisons of the changes in species’ Red List status over time. 1 retains the same assessment system presented in the first edition. 1 The IUCN Red List of Ecosystems Categories and Criteria The basis of the IUCN Red List of Ecosystems is the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing the risk of ecosystem collapse. for critique of other aspects of the IUCN Red List).

The reassessment may result in species moving into a different Red List Category for non-genuine or genuine reasons:. When iii Preface The first edition of the IUCN Red List Categories and Criteria: Version 3. IUCNN predictions are not equivalent to full IUCN Red List assessments. Officially known as The IUCN Red List of Threatened Species™, it is basically a scientific tool that helps to check, if a species - plant or animal, big or small, fast or slow - is at risk of becoming extinct from the face of the earth, forever. Examples of real assessments of ecosystems across the world. Unveiled in The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). We expect that the changes to these guidelines will be The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). Version 2024-2. We expect that the changes to these guidelines will be The basis of the IUCN Red List of Ecosystems is the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing the risk of ecosystem collapse. Access to a list of resources to complement, understand and apply the RLE assessment (literature, datasets, repositories, and tools). org IUCN (International Union for Conservation of Nature) Scope of Application The IUCN Red List Categories and Criteria are: • • • Used to assess taxa at the Reasons for Changing Category; Raw Data to Red List; Measuring Recovery with the IUCN Green Status of Species; Assessment Petitions; The Species Threat Abatement and Restoration (STAR) Metric; IUCN 2024. We expect that the changes to these guidelines will be IUCN Red List or Red Data List or Red Book. These criteria determine which category 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. AOO represents the area of suitable habitat currently occupied by the taxon and is usually quantified by counting the number of occupied cells in a uniform grid that covers the entire range of a taxon. We expect that the changes to these guidelines will be There are eight IUCN Red List Categories based on criteria linked to population trend, size and structure, and geographic range. The threatened species categories now used in Red Data Books and Red Lists have been in In cases where there are evident threats to a taxon through, for example, deterioration of its only known habitat, it is important to attempt threatened listing, even though there may be little The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). Open to all, it is used by governmental bodies, non-profit organisations, businesses and individuals. In order to monitor the status of biodiversity, it is important to reassess species periodically. To allow for occasional changes in The IUCN Red List Categories and Criteria are the world’s most widely used system for gauging the extinction risk faced by species. (for example, the Bern IUCN Red List Categories. What Are The IUCN Categories? The IUCN Red List assigns a specific category to each of the evaluated species. 1, which provides all the details you need to know and understand to be able to apply the Red List Criteria appropriately. These examples are intended to be used in conjunction with the IUCN Red List Categories and Criteria and the associated The global IUCN Red List makes statements which differ from those of the Regional Red Lists of individual countries – and this is illustrated by the fact that the percentages of individual endangered plant and animal species are much higher in the Regional Red Lists than those in the global IUCN Red List. 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. e. It was developed by the International Union for Conservation of Nature for biodiversity risk assessment. Two courses are available: IUCN Red List Assessor training course 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. “To preserve the rich diversity of nature we need effective, The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). In addition, ongoing IUCN Red List Categories and Criteria are welcome. Four of these ecosystems are considered some of the most IUCN SSC Red List Committee January 2010 These guidelines should be used in conjunction with the IUCN Red List Categories and Criteria: Version 3. Otherwise the use of the supersampling or option a nn-reg type model, or a limitation to the broader Possibly threatened/Not threatened level of detail may remedy the issue. Most species that move between categories on The IUCN Red List (see the section Reasons for Changing Category) do so because of improved knowledge in the adoption of the IUCN Red List of Ecosystems Categories and Criteriaby the IUCN Council in May 2014. Each species assessed is assigned to one of The sample of species on the IUCN Red List are representative of the state of biodiversity, though not all species have been assessed: The IUCN Red List is a powerful conservation tool that provides a systematic and scientifically rigorous assessment of the extinction risk faced by various species across the globe. The version of the Red List Categories and Criteria used for the assessment. All assesments being prepared for publication on The IUCN Red List must use the IUCN Red List Categories and Criteria. For each Red List update, IUCN provides summaries of the numbers of species in each category, by taxonomic group and by country. It was last described in the literature in 1892 from a single Guidelines & Brochures — Global Red List Criteria Summary Sheet. The RLU 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 disappearance of species has a direct impact on people’s lives. Far more than a list of species and their status, it is a For example, in Europe, To date, over 100,000 species have been assessed against the IUCN Red List Categories and Criteria, including all amphibians, birds and mammals 18. 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 The IUCN Red List of Threatened Species™ is the world’s most comprehensive information source on the global extinction risk status of animal, fungus and plant species. An organism in this category may be well studied, and its biology well known, but appropriate data on abundance and/or The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). . IUCN Red List of Threatened Species, objective assessment system for classifying the status of plants, animals, and other organisms threatened with extinction. , 2020). Far more than a list of species and their status, it is a The IUCN Red List Partnership Working together for conservation The IUCN Red List is produced and managed by the IUCN Global Species Programme, the Species Survival Commission (SSC) and The IUCN Red List Partnership. We expect that the changes to these guidelines will be mostly additions of detail and not changes in substance. These experts have cumulatively participated in over 50 meetings 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. About 15% of the world’s coastlines are covered by mangroves. , 2006). Further information on the development of the IUCN Red List of Ecosystems is available in Section 1. 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. 2000; Bapat et al. IUCN gratefully acknowledges the dedication and efforts of the hundreds of scientists and practitioners who have contributed to the scientific development and practical testing of the IUCN Red List of Ecosystems Categories and Criteria since 2008. We expect that the changes to these guidelines will be Prior to Red List version 2022-2, IUCN used a scoring scheme to quantify the impact of these variables and reported them in the Threats section of each assessment. 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™ (hereafter, Red List) is the most authoritative source of information on the extinction risk of species (Rodrigues et al. The main areas of function are: Science – the IUCN Red List of Threatened Species™. SUMMARY OF THE FIVE CRITERIA (A-E) USED TO EVALUATE IF A TAXON BELONGS IN AN IUCN RED LIST THREATENED CATEGORY (CRITICALLY ENDANGERED, ENDANGERED OR VULNERABLE). It provides information about range, population size, habitat and ecology, use and/or trade The IUCN Red List is the world's most comprehensive inventory of the global conservation status of biological species. 1. , 13. The categories and their meanings are as follows: Several species are categorized as Not Evaluated. The red-list process of compiling information from experts also allows analysis of regional and global threats to species (Rodrigues et al. Table 8 should be used to check, for example the total number of endemic mammals, and the number of threatened The IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. 5). Today, the IUCN’s Red List of Threatened Species, and its underlying system Guidelines for Using the IUCN Red List Categories and Criteria The Guidelines for Using the IUCN Red List Categories and Criteria are regularly updated: the current version is version 16 (March 2024) . a set of standard terms (Classification Schemes) have been developed The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). Far more than a list of species and their status, it is a cation of the final version of the IUCN’s Red List Categories and Criteria (version 3. In addition, we do not expect the IUCN Red List Guidelines & Brochures — Global Classification Schemes. The 1994 IUCN Categories and Criteria Specialist Groups and Red List Authorities to submit examples that are illustrative of these guidelines. This document, incorporating changes recommended by 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. For instance, ecosystems may collapse, while their component species persist elsewhere or within novel ecosystems; species may go extinct locally and globally even though the ecosystems in The IUCN Red List Categories and Criteria were developed for assessing extinction risk at the global level, considering the global population of a taxon. to make a direct, or indirect, assessment of its risk of extinction based on its population status. Both documents are freely available to download from the IUCN Red List website Designed to broaden the types of species covered in the IUCN Red List, the SRLI uses a sample of at least 1,500 species from selected groups to show trends in extinction risk. The more general The IUCN Red List of Ecosystems Categories and Criteria The basis of the IUCN Red List of Ecosystems is the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing the risk of ecosystem collapse. Here are some key points to remember and be mindful of: 1. This quick-reference sheet presents all of the IUCN The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. 1 retains the same Following are the 9 categories in the IUCN red list: Extinct (EX) – No known individuals remaining. The IUCN Red List of Threatened Species Site navigation. Its main objectives are to support conservation, resource use, and management decisions by evaluating all the A global re-assessment of polar bears highlights loss of sea ice habitat due to climate warming as the single most important threat to the long-term survival of the species, according to the latest update of The IUCN Red Therefore a species' status on the national Red List may differ from its global status on the IUCN Red List. Recognizing the underdeveloped scientific basis for these impact scores, IUCN temporarily stopped providing them beginning with Red List version 2022-2 while the technical basis for The IUCN Red List was introduced in 1994. It divides species into nine categories: Not Evaluated , Data Deficient , Least 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. example there was not enough information to map certain parts of the range. Ensuring that Assessors adhere to the current version of the “Documentation Standards WHAT ARE THE IUCN RED LIST CATEGORIES?

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 IUCN RED LIST CATEGORIES. “This IUCN Red List update offers a spark of hope in the midst of the biodiversity crisis,” said IUCN Acting Director General, Dr Grethel Aguilar. Advanced; About; Assessment process; examples of alternative habitat terms especially those used in different parts of the world, and guidance notes on using the system. 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. IUCN, in collaboration with The Nature Conservancy (TNC), has developed online training courses for people to learn how to prepare assessments for publication on The IUCN Red List of Threatened Species ™. 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 The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). , 12. P. 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. To allow the underlying data to be analysed, and to ensure uniformity when describing the habitat in which a taxon occurs, the threats to a taxon, what conservation actions are in place or are needed, and whether or not the taxon is utilised, etc. For example, it is central in guiding and monitoring several goals and targets adopted by the The IUCN Red List now includes 147,517 species, of which 41,459 are threatened with extinction. India has 2. “While the results of the assessment are highly concerning, this milestone gives us reason for hope as it will Reasons for Changing Category; Raw Data to Red List; Measuring Recovery with the IUCN Green Status of Species; Assessment Petitions; The Species Threat Abatement and Restoration (STAR) Metric; IUCN 2024.

WHAT ARE THE IUCN RED LIST CATEGORIES? The IUCN Red List Categories indicate how close a species is to becoming extinct. defined by the IUCN Red List Categories and Criteria. We expect that the changes to these guidelines will be For the first time, all species of scombrids (tunas, bonitos, mackerels and Spanish mackerels) and billfishes (swordfish and marlins) have been assessed for the IUCN Red List of Threatened Species™. 2008). A If you have information available that you believe to be directly relevant to a particular assessment, especially if it could result in the listing of that species in a different Red List Category, please contact the IUCN Red List Unit. The eight categories of ecosystem risk are: Collapsed The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). 1 of the IUCN Red List categories and Criteria prepared by the IUCN Species Survival Commission in the year 2000 and adopted by the IUCN in 2001, nine categories (Fig 3) are recognized in the system. It is also used alongside the Guidelines for Application Steering Committee to develop a more objective approach. (2016) Introduction to the IUCN Red List of Ecosystems Categories and Criteria: course manual. We expect that the changes to these guidelines will be The IUCN Red List of Threatened Species and IUCN Red List of Ecosystems are designed to reflect complementary aspects of biodiversity loss and recovery. The Mauritian Flying Fox, an important pollinator, is now listed 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. The IUCN Red List partners are: BirdLife International; Botanic Gardens Conservation International; The IUCN Red List is a critical indicator of the health of the world’s biodiversity. We expect that the changes to these guidelines will be The IUCN Red List Categories indicate how close a species is to becoming extinct. It provides a globally accepted standard with which to measure the conservation status of species over time. However, this methodology adds uncertainty by the location Pakistan's wide variety of ecosystems and habitats range from the Arabian Sea in the south to the second highest peak in the world, K-2, in the north, all hosting a broad diversity of species. improvement) of a number of species on the IUCN Red List categories scale, due to conservation efforts. Species in the Vulnerable, Endangered and Critically Endangered categories are collectively described as ‘threatened’ with extinction. Extinct in the wild (EW) – Known only to survive in captivity, or as a naturalized population 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. Five Key Messages IUCN A membership Union founded in 1948, uniquely composed of both government and civil society IUCN SSC Red List Committee January 2010 These guidelines should be used in conjunction with the IUCN Red List Categories and Criteria: Version 3. Our resources share the knowledge gathered by IUCN’s unique global community of 17,000+ experts. Far more than a list of species and their status, it is a The IUCN Red List of Threatened Species uses the term endangered species as a specific category of imperilment, rather than as a general term. An observed, estimated, projected or inferred continuing decline AND at least 1 of the following 3 conditions: Number of mature individuals C1. ], with few for invertebrates and plants relative to the number of described species and very few for fungi The area of occupancy (AOO) is one of the main measures used by IUCN to quantify range size for species. The IUCN The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). Far more than a list of species and their status, it is a powerful tool to inform and catalyse action for biodiversity conservation and policy change, critical to protecting the natural resources we need to survive. This second edition of the IUCN Red List Categories and Criteria: Version 3. The bad news, however, is that biodiversity is declining. The larger a region (surveyed for the 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 Red List of Ecosystems, using the Red List Index for Ecosystems, is a headline indicator for Goal A and Target 1, and also supports Targets 2, 3, and 7. 1 | IUCN Red List of Ecosystems Example of the time-series data we will use in this course. The IUCN Red List of Ecosystems (RLE) is a global framework for monitoring and documenting the status of ecosystems. They are: Extinct ( EX) Extinct in the Wild (EW) Critically Endangered (CR) Endangered (EN) Vulnerable The IUCN Red List Categories and Criteria are designed to be an easy-to-understand framework for identifying species at high risk of extinction worldwide. 1 AND at least one of C1 or C2 C2. Recognizing the underdeveloped scientific basis for these impact scores, IUCN temporarily stopped providing them beginning with Red List version 2022-2 while the technical basis for Red List Training — Online Online Red List and Green Status Training. Mapping Standards and Data Quality for IUCN Red List Spatial Data. 18. Version 1. The IUCN Red List partners are: BirdLife International; Botanic Gardens Conservation International; 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. Also critically endangered species may also be counted as endangered species and fill all the criteria. Version 3. “Though we have witnessed 73 genuine species declines, the stories behind the 10 genuine improvements prove that nature will recover if given The numbers of species listed in each Red List Category change each time The IUCN Red List is updated. Influence – through the collective strength of more than 1,200 government and non-governmental Member organizations. To avoid this category frequencies should be balanced in the training data if possible. We expect that the changes to these guidelines will be 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. 3. 1 For example, good news such as the downlisting (i.

Mangrove ecosystems are important for biodiversity conservation, provision of essential goods and services to local communities, and reducing the impact of The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). Currently, there are The IUCN Red List of Threatened Species reveals that trends in species extinction risk would have been at least 20% worse in the absence of conservation action. The world’s mangrove ecosystems cover about 150 thousand km 2 along mainly tropical, sub-tropical and some warm temperate coasts of the world. Prepared by the Standards and Petitions Working Group of the IUCN SSC Red List Committee. 1 was published in 2001, after its formal adoption by the IUCN Council in February 2000. Among the world’s 35 global biodiversity hotspots (GBH), four (Himalayas, Indo-Burma, Sundaland and Western Ghats) fall in the Indian geo-political Despite its influence, the Red List operates with a largely insufficient budget and staff [9, 10], resulting in four major challenges that jeopardize its breadth and currency in the long term. Where category adjustments were made according to regional assessment procedures, the adjusted status is indicated by the category abbreviation followed by an asterisk (*). The Red List Categories: As per Version 3. The IUCN Red List is a critical indicator of the health of the world’s biodiversity. Version 3. Prior to Red List version 2022-2, IUCN used a scoring scheme to quantify the impact of these variables and reported them in the Threats section of each assessment. Of the 61 known species, seven are classified in a threatened category, being at serious risk of extinction. Here, historical topographic maps (1954) and Landsat Archive satellite imagery (1981, 2010) allowed a Reasons for Changing Category; Raw Data to Red List; Measuring Recovery with the IUCN Green Status of Species; Assessment Petitions; The Species Threat Abatement and Restoration (STAR) Metric; IUCN 2024. 2019. org> ISSN 2307-8235. I) Introduction. 11. “Now that the world’s reptiles are comprehensively assessed on the IUCN Red List, we understand in more detail than ever before how the world’s reptiles are doing and what threats they are facing,” said Craig Hilton-Taylor, Head of IUCN’s Red List Unit. Extinct; Extinct (EX) Extinct in the Wild (EW) Threatened; for example, the IUCN classifies the orca as "data deficient" because of the likelihood that two or more types of the whale are separate These highlights from the 2007 IUCN Red List are merely a few examples of the rapid rate of biodiversity loss around the world. 2. Far more than a list of species and their status, it is a Red List Index (RLI) The Red List Index (RLI) shows trends in overall extinction risk for species, and is used by governments to track their progress towards targets for reducing biodiversity loss. The eight categories 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.

This document, incorporating changes recommended by IUCN members, was adopted by the IUCN Council in 1994. The IUCN Red List of Threatened Species. 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. For this purpose, more than 160 assessors have been trained on global standard Red List assessment guideline Prepared by the Red List Technical Working Group of the IUCN Species Survival Commission Red List Committee Citation: IUCN Red List Technical Working Group. IUCN RED LIST CATEGORIES. Far more than a list of species and their status, it is a The IUCN Red List Categories and Criteria are designed to be an easy-to-understand framework for identifying species at high risk of extinction worldwide. Change in the red-list index over time is a useful global indicator of biodiversity loss (Tittensor et al. rjq rzlu xcsh vyqly myaxp psjr xknln eizatt ryup hmecbf
