The IUCN Red List of Threatened Species is the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. To date more than 76,000 species have been assessed - an incredible achievement. However, our work is nowhere near complete. We need to more than double the number of wild species (plants, animals and fungi) assessed. Our new goal is to assess at least 160,000 species by 2020. Meeting this goal will provide the most up-to-date indication of the health of the world’s biodiversity to guide critical conservation action.

Please help us make the Red List a more complete ‘Barometer of Life’ and an even more powerful conservation tool. Will you help? Sign the Pledge.
