Q. Rajaji Raghav Biosphere Reserve, recently designated as India's first private biosphere, is located in which state?
Answer: Uttarakhand
Notes: The Rajaji Raghati Biosphere (RRB) within Uttarakhand's Rajaji National Park spans 35 acres, focusing on rare and endangered native trees. Founded by environmentalists Jai Dhar Gupta and Vijay Dhasmana, it's India's first biosphere within a tiger reserve. It restores barren land by removing non-native eucalyptus trees and employs water retention techniques. The initiative fights threats such as poaching and mining, aiming to protect and revive native ecosystems.
