Q391. The following question consists of two statements, Assertion (A) and Reason (R). Select the correct answer from the options given below: Assertion (A): Conservation Reserves act as buffer zones or migration corridors between established national parks and sanctuaries. Reason (R): They are typically declared on government-owned land adjacent to national parks and sanctuaries to enhance landscape-level conservation.
Explanation
Conservation Reserves are established on government-owned land, particularly in areas adjacent to National Parks and Sanctuaries. These reserves are designed to act as vital buffer zones or migratory corridors, enhancing conservation at the landscape level. Because they provide connectivity between established protected areas, the reasoning accurately explains the strategic ecological purpose of declaring these specific regions as Conservation Reserves today.

Q392. All of the following are recognized Biosphere Reserves in India, EXCEPT:
Explanation
India has identified eighteen biosphere reserves, including Cold Desert, Seshachalam Hills, and Achanakmar-Amarkantak. While Chilika Lake is a highly significant wetland, a Ramsar site, and a major biodiversity hotspot, it is not officially notified as one of the eighteen Biosphere Reserves under the national program. It is primarily managed as a wetland ecosystem rather than a multi-zoned biosphere reserve under MAB.

Q393. What is the most appropriate purpose of declaring Eco-Sensitive Zones (ESZs) around National Parks and Wildlife Sanctuaries?
Explanation
Eco-Sensitive Zones are notified around National Parks and Sanctuaries to create a transition area between highly protected habitats and areas with intensive human activity. These zones act as "shock absorbers" by regulating certain activities to minimize the negative impact of development on the core ecosystem. They help maintain ecological stability without requiring the total relocation of all local human populations nearby.

Q394. The Desert National Park in Rajasthan is famous for harboring a significant population of which critically endangered state bird?
Explanation
Desert National Park, located in the Jaisalmer and Barmer districts, is one of the last strongholds of the Great Indian Bustard. Locally known as Godawan, this critically endangered bird is the state bird of Rajasthan. The park’s vast grasslands and scrublands provide the essential habitat required for the survival and breeding of this majestic and highly threatened species in western India.

Q395. Read the following statements regarding Ranthambore National Park: I. It is situated at the junction of the Aravalli and Vindhya hill ranges. II. It is renowned for its Bengal Tiger population. III. It is located in the Jaisalmer district of Rajasthan. Which of the given statements is/are correct?
Explanation
Ranthambore National Park is famously situated at the junction of the Aravalli and Vindhya mountain ranges and is a major site for Bengal tiger conservation. However, it is located in the Sawai Madhopur district, not Jaisalmer. Therefore, while the geological and biological descriptions are accurate, the geographical location provided in the third statement is incorrect, making only the first two valid.

Q398. Which type of vegetation is most dominant in the Desert National Park of Rajasthan?
Explanation
The Desert National Park is situated within the Thar Desert and experiences extreme arid conditions. Consequently, the dominant vegetation consists of tropical thorn forests and scrublands. These ecosystems are characterized by drought-resistant species like Khejri, Rohida, and various grasses. This vegetation is perfectly adapted to the low rainfall and high temperatures of the western Rajasthan landscape, supporting specialized desert wildlife.
