IUCN's work focuses on valuing and conserving nature, ensuring effective and equitable governance of its use, and deploying nature-based solutions to global challenges in climate, food and development.
A Red Data Book is a document that keeps a record of all the endangered species of animals, plants, and fungi in a country or a state. The International Union for Conservation of Nature established the Red Data Book to safeguard the rare species of flora and fauna on Earth, to prevent their extinction.
