Detailed Solution & Explanation

Key Points

• Species that are in danger of extinction are classified as Endangered.
• The IUCN (International Union for Conservation of Nature), founded in 1948 and headquartered in Gland, Switzerland, maintains the Red List of Threatened Species using this classification.
• The IUCN Red List categories in descending order of risk are: Extinct (EX), Extinct in the Wild (EW), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD) and Not Evaluated (NE).
• The three categories CR, EN and VU together constitute the "Threatened" group.
• Definitions matter here: Vulnerable means a high risk of endangerment in the wild; Endangered means a high risk of extinction; and Critically Endangered means an extremely high risk of extinction in the immediate future.

Exam Tip

• Indian examples are frequently asked — the Great Indian Bustard and Gharial are Critically Endangered, while the Bengal Tiger and Asiatic Lion are Endangered.
