Data Repository
Data Repository for IUCN Red List Data used in Published Papers
Spatial and tabular data from The IUCN Red List are used in many analyses and the results published in scientific papers. Journals often require the datasets used for such papers to be made permanently available in a public repository. Hence this repository has been established for Red List datasets used in analyses and publications that are primarily lead by people associated with IUCN.
This repository meets the usual criteria required of such data repositories:
- Ensure long-term persistence and preservation of datasets in their published form.
- Provide stable persistent identifiers for submitted datasets (initially this will be a stable URL but a DOI will also be provided in the future).
- The data are freely available for download and use under a CC-BY-NC license following the IUCN Red List Terms and Conditions of Use. Users need a free user account to access the downloads.
- The data used in the analyses are published or have been accepted for publication on The IUCN Red List and will have been subject to review following the IUCN Red List Rules of Procedure.

Abstract
Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action. Ongoing developments in taxonomy, threatening processes, and research further underscore the need for reassessment. The second Global Amphibian Assessment evaluates 8,011 species for The IUCN Red List and finds amphibians are the most threatened vertebrate class (40.7%). The updated Red List Index shows their status is deteriorating globally, particularly for salamanders and the Neotropics. Disease and habitat loss drove 91% of status deteriorations between 1980–2004. Ongoing and projected climate change effects are now of increasing concern, driving 39% of status deteriorations since 2004, followed by habitat loss (37%). While signs of species recoveries incentivise immediate conservation action, scaled-up investment is urgently needed to reverse current trends.
Usage notes
The dataset contains all of the tabular and spatial data analysed in Luedtke et al. 2023, Ongoing declines for the world's amphibians in the face of emerging threats. The Readme file contains a detailed explanation of each file and variable in the dataset. Information regarding the methods used for the analyses can be found in the associated paper referenced above.
