The IUCN (International Union for Conservation of Nature) Red List, also referred to as the Red Data Book, is a global catalog of species facing extinction threats. It evaluates species' conservation status, documenting population trends, habitats, and threats. The list has categorized various species into:

•Extinct

•Extinct in the Wild

•Critically Endangered •Endangered

•Vulnerable

•Near Threatened

•Least Concern

•Data Deficient

•Not Evaluated

This vital resource enables conservationists, researchers, and policymakers to pinpoint species requiring protection and devise effective conservation strategies.
