The IUCN Red List of Threatened Species is a critical indicator of the health of the world’s biodiversity – a Barometer of Life – telling us what we need to know to save wild species. So far, over 150,300 species have been assessed for The IUCN Red List. Our goal is to have assessed 160,000.

Our urgent targets are to:

Fund the reassessment of all comprehensively assessed groups. This is essential to continue monitoring the changing status of species across the world.
Fund the assessment of taxa not yet represented on The IUCN Red List. This will help expand coverage to a more representative subset of the planet's biodiversity.

For more information, see the Barometer of Life page.
