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 2021-3) are listed below.

|IUCN Red List 2017-2020 Report|
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.
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).
This report captures the highlights of the conservation impact of The IUCN Red List of Threatened Species over the 2017–2020 quadrennial. 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 (2017-2020). To download this report, go to the Resources and Publications section on the website.
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.
The 2021-3 Red List introduced the first Green Status assessments to the IUCN Red List website. Website users can now filter their search results to find species with Green Status assessments. On the Advanced Search page, scroll down to the "FILTER ON" section to see this filter.
For all species with a Green Status assessment, the search results page displays the Green Status alongside the Red List status. The two-letter abbreviations for Green Status assessments refer to species recovery categories: Indeterminate (ID); Non-Depleted (ND); Fully Recovered (FR); Slightly Depleted (SD); Moderately Depleted (MD); Largely Depleted (LD); Critically Depleted (CD); Extinct in the Wild (EW); and Extinct (EX). For detailed guidelines and Green Status assessment tools, see here.
The assessment page now displays Green Status of Species (GSS) assessments where these are available. The 2021-3 update includes the first GSS assessments for 26 species, marking a major step forward for the IUCN Red List. Now, Red List users can easily see the current risk of extinction (Red List assessment) and the chances of recovery (GSS assessment) for these species. More GSS assessments will be published in future updates of the IUCN Red List.
Note that the Red List assessment and the Green Status assessment have separate citations. These citations appear above the teardrop category image for each assessment. Information icons have also been added to explain the purpose of these different assessments: to see the information panel, place your cursor on the "i" icon next to "THE RED LIST ASSESSMENT" and "THE GREEN STATUS ASSESSMENT" text.
For species with Green Status assessments, information relating to these assessments is displayed throughout the assessment page, highlighted by green text.
Green Status of Species (GSS) assessments have supplementary information documents attached to them. Development is underway to make this information available via the "Download" button in the assessment. Meanwhile, these documents are available on a temporary page: Green Status Supplementary Information.
Currently, the GSS supplementary information documents include graphs showing the Green Scores for the assessed species; the list of past, current and planned future conservation actions; and the list of past, current and expected future threats across the species' range.
The assessment page includes a link to the temporary supplementary information page; to go directly to the Green Status Supplementary Information page, click here.
A short abstract has now been added to the assessment page, allowing Red List assessments to be more easily found by online academic search engines.
From 2021-3, the text summary no longer appears at the end of the assessment page. This has been replaced by a text overview panel, separate from the main assessment, which users can scroll down through to read all the assessment text. To open this panel, click on the Text Overview button.
In addition to introducing the Green Status assessments, abstracts and the text overview panel, the 2021-3 Red List brings in a range of other changes to the assessment pages, including:
- A hyperlink to the assessment details now appears at the top of the page, next to the link back to your search results.
- For all species with a Green Status assessment, the scale bar that shows which Red List category the species is listed under in relation to the other available categories no longer appears at the top of the assessment page. Instead, this now appears in the assessment details to accommodate displaying the extra GSS information on the page. A new scale bar has also been introduced to display the Green Status categories.
For species that do not have a Green Status assessment, the Red List scale bar still appears at the top of the assessment page.
- The assessment summary information has been reduced by removing the summary of habitats, threats and conservation actions codes from there. These codes are provided in the detailed assessment, and removing these from the summary information section shortens the length of the assessment pages and makes them easier to read through.
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.
