IUCN marks 60th anniversary of Red List with year-long campaign to accelerate species assessments
Supporters of IUCN gathered on the sidelines of the 16th CoP to the UN Convention on Biodiversity in Cali, Colombia on 28 October to celebrate the 60th anniversary of the IUCN Red List of Threatened Species and to chart an ambitious path forwards for expanding the “barometer of life”.

What is The IUCN Red List?
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.
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 powerful tool to inform and catalyze action for biodiversity conservation and policy change, critical to protecting the natural resources we need to survive. It provides information about range, population size, habitat and ecology, use and/or trade, threats, and conservation actions that will help inform necessary conservation decisions.
The IUCN Red List Categories and Criteria
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 divides species into nine categories: Not Evaluated, Data Deficient, Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild and Extinct.
Our goals
To date, more than 163,000 species have been assessed for The IUCN Red List.
This is an incredible achievement. However, our work is nowhere near complete. We need to substantially increase the number of wild species assessed, particularly plants, invertebrates and fungi.
Our current goals, based on the IUCN Red List Strategic Plan (2021-2030), are to have 260,000 species assessed and to reassess 142,000 of those species to ensure the information on their status is up-to-date so that we can monitor trends in change of status. Meeting these goals will provide the most up-to-date indication of the health of the world’s biodiversity to guide critical conservation action. This is only achievable with support from people like you.
