IUCN Red List 50th Rhino

IUCN Red List of Threatened Species Turns 50

In 2014, we are celebrating the significant contribution of The IUCN Red List of Threatened Species in guiding conservation action and policy over the past 50 years. The IUCN Red List is an invaluable conservation resource for scientists, students, teachers, and decision-makers. It is the ONLY comprehensive base-line of the status of animal, plant, and fungi available and acts as a health check for our planet - a Barometer of Life.

For more information and to learn about upcoming events and activities in the United States and Canada follow @amazingSpecies and @IUCNDC.

We appreciate your support of our important work learning about and describing biodiversity and its connections to human livelihoods across the world. Please consider a tax-deductable donation to IUCN-US to help us continue this important work.
