When was IUCN Red List created?

The IUCN Red List (also known as the Red List) is the world's most comprehensive information source on the global extinction risk status of animal, plant and fungus species. It is a critical indicator of the health of the world's biodiversity. The Red List was created in 1964 as one of IUCN's key conservation assessment tools and serves as a warning system, highlighting priority species across the globe in need of conservation action.
