Along with pages being regularly updated to reflect the new data available in each Red List update, new pages, tools and functionality are added to The IUCN Red List website at any time throughout the year. The most recent updates and additions to the Red List website (version 2022-2) are listed below.
For a list of previous updates and additions (since the start of 2020), click here.
Each time The IUCN Red List is updated, the Summary Statistics page (in the Resources and Publications section) is also updated to provide statistics for the most recent version of the Red List. The Summary Statistics page also includes links to the automated statistics tables. Note that from the 2022-1 Red List onwards, the calculation for proportion of threatened species now includes threatened (CR, EN and VU) and Extinct in the Wild (EW) species.
Each time The IUCN Red List is updated, the Spatial Data Download page (in the Resources and Publications section) is also updated to provide all the current map data for various groups of species (including polygon spatial data and point data, where available).
In 2022, the IUCN Red List, in collaboration with ABQ Biopark, initiated a series of webinars about the IUCN Red List. The new IUCN Red List webinars page makes these recorded webinars freely available to everyone. This page now includes all three Red List webinars from 2022, focusing on the Red List Criteria, preparing distribution maps, and using the Species Information Service (SIS). It also includes links to a series of webinars specifically about national Red Lists, which compliment the IUCN Red List webinars.
The IUCN Red List of Threatened Species often inspires scientific research and comments. As new papers are published, the Red List website adds links to those papers and journals to help Red List users to find the most current and relevant analyses and information available. Explore the recently published papers in the Scientific Papers section in Resources and Publications.
Building on discussions over at least the last decade between the IUCN CEESP-SSC Sustainable Use and Livelihoods Specialist Group and the IUCN SSC Red List Committee, with insights gained from the IPBES Indigenous & Local Knowledge (ILK) Approach, IUCN released the guidance document Application of Indigenous & Local Knowledge (ILK) in IUCN Red List assessments. This document aims to examine all the issues and general principles surrounding the application of indigenous and local knowledge (ILK) in the IUCN Red List of Threatened Species and to outline some key steps to enhance this application in Red List assessments. This document is available to download (in English, French and Spanish) from here.
Some minor text corrections have been addressed in The Guidelines for Using the IUCN Red List Categories and Criteria, updating it to version 15.1 (July 2022). Version 15.1 is also now available in Portuguese. You can download version 15.1 of the Red List Guidelines from here.
In July 2022, the Guidelines for Appropriate Uses of Red List Data were updated to version 4.0. Changes to this document include:
- Annex 1: for reporting purposes, the revised formulas for proportion of threatened species now include Extinct in the Wild (EW) species with Critically Endangered (CR), Endangered (EN) and Vulnerable (VU) species.
- Annexes 2 and 3: hyperlinks to additional resources have been updated.
- Annex 4: this new Annex provides Guidelines for the Appropriate Use of IUCN Red List data in Harvesting of Threatened Species.
The updated guidelines and the annexes are available here.
The assessment page now includes a one-click copy tool for assessment citations. Click on the copy icon to the right of the citation to copy.
The Species Information Service (SIS) is the data management system used by the IUCN Red List to allow assessors from around the world to access, edit and submit assessments for publication on the Red List website. The SIS News and Updates page is updated regularly as new data fields are added and new tools and functionality are brought into SIS.
Eleven new Green Status of Species (GSS) assessments were added to the IUCN Red List (version 2022-1), including the American Bison, American Horseshoe Crab, Mauritius Kestrel, and Mountain Chicken. This brings the current number of species with GSS assessments to 37. To find the list of all GSS assessments, open the Advanced Search page, scroll down to the "FILTER ON" section, and click on the checkbox next to the "Green Status" option.
The online IUCN Red List Assessor training course for has been available since 2013. In 2022, a new online course for the IUCN Green Status of Species was released, developed in partnership with Re:wild, University of Oxford and the Zoological Society of London. The Green Status of Species training course is available on the TNC's ConservationTraining website, alongside the Red List Assessor training course. A link to the new course is now included in the Online Red List and Green Status Training page.
Prior to Red List version 2022-2, IUCN used a scoring scheme to quantify the impact of threats coded for species, based on the timing, scope and severity of these threats. Threat scores were presented in the Threats section in the assessments. However, IUCN now recognises the underdeveloped scientific basis for these impact scores. From version 2022-2, IUCN temporarily removed the threat scores from assessments, while the technical basis for assigning threats and calculating threat impact scores is under review. For more information, see the Threat Classification Scheme page.
