IUCN Red List Version 2026-1 Released
Context
The International Union for Conservation of Nature (IUCN) has released Version 2026-1 of its Red List of Threatened Species, the world’s most comprehensive assessment of the conservation status of species.
Key Highlights
- The latest Red List assesses 175,909 species, of which 49,505 species (around 28%) are classified as threatened with extinction.
- Hydrothermal-vent molluscs face growing risks from proposed deep-sea mining activities.
- 125 out of 201 known endemic hydrothermal-vent mollusc species (62%) are now threatened with extinction.
- The Lirapex felix snail has been listed as Critically Endangered due to mineral exploration affecting its Indian Ocean habitat.
- In contrast, more than 30 hydrothermal-vent mollusc species located within Marine Protected Areas, where deep-sea mining is prohibited, continue to be classified as Least Concern.
- Conservation assessments confirmed the extinction of five Australian marsupial species.
- The numbat has shown encouraging recovery and has been moved from Endangered to Near Threatened, reflecting the success of predator control, captive breeding, translocation, and habitat protection measures.
- The desert rain frog has been reclassified from Near Threatened to Vulnerable, primarily due to habitat degradation caused by diamond mining and energy infrastructure projects in Namibia and South Africa.
- Around 95% of reassessed rowan, whitebeam, and service-tree species native to the United Kingdom and Ireland continue to remain under threat.
- Wilmott’s whitebeam has now been placed in the Critically Endangered category.
- For the first time, flowering plants have been incorporated into the EDGE (Evolutionarily Distinct and Globally Endangered) framework. This initiative prioritises species that are both highly threatened and evolutionarily unique.
IUCN Red List?
- The IUCN Red List of Threatened Species is the world’s leading global inventory that evaluates the extinction risk of animals, plants, and fungi. It is maintained by the IUCN Species Survival Commission (SSC).
- Species are assessed using five scientific criteria:
- Population decline
- Geographic distribution
- Small population size and continuing decline
- Very small or restricted population
- Quantitative analysis of extinction probability
- The Red List classifies species into nine categories:
- Not Evaluated (NE)
- Data Deficient (DD)
- Least Concern (LC)
- Near Threatened (NT)
- Vulnerable (VU)
- Endangered (EN)
- Critically Endangered (CR)
- Extinct in the Wild (EW)
- Extinct (EX)
- The categories Vulnerable, Endangered, and Critically Endangered are collectively recognised as the threatened categories.
- Red List assessments evaluate a species across its entire global distribution, rather than limiting the assessment to conditions within a single country or region.
