A campaign to support The IUCN Red List

THE GOAL: 160,000 by 2020

To date more than 82,900 species have been assessed for The IUCN Red List. This is an incredible achievement. However, our work is nowhere near complete. We need to increase the number of wild species (plants, animals and fungi) assessed. Our new goal is 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. This is only achievable with support from people like you.
We are more than halfway to our goal! Will you help? Sign the Pledge.

Assessment Goal 14,500

Species Assessed 49 (2015)

To reach 160,000 species by 2020, we need to do three things: 

  • Increase the number of experts trained to carry out IUCN Red List assessments
  • Significantly increase the number of species being assessed each year
  • Conduct regular reassessments of species groups

Conservation Works

The Black-footed Ferret (Mustela nigripes) was considered Extinct in the Wild in 1996. A captive breeding program initiated in 1985 by the Wyoming Game and Fish Department in cooperation with the US Fish and Wildlife Service resulted in more than 6,000 Black-footed Ferrets being born in captivity. Ferrets have been reintroduced in western US states and in Mexico. In 2008 this species was reassessed for the IUCN Red List as Endangered. Ongoing conservation is essential to continue their recovery.

If not for conservation efforts, the Black-footed Ferret could have disappeared forever.
