(a) 1 and 2 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3 Answer: (c) 1 and 3 only Explanation: About Nahargarh Wildlife Sanctuary: Nahargarh Wildlife Sanctuary is situated in Rajasthan within the Aravalli hill range, one of the oldest mountain systems in the world. It forms part of an important ecological landscape that connects fragmented forest patches across the region. Statement 1 is correct: The sanctuary is ecologically linked with forest corridors extending towards Ranthambore Tiger Reserve, which enhances wildlife movement, particularly for species like leopards. Statement 2 is not correct: The sanctuary does not have tropical evergreen forests. Instead, it is characterized by dry deciduous forests typical of semi-arid regions, with vegetation such as dhok, babool, and khejri. This is a common UPSC trap involving forest-type misclassification. Statement 3 is correct: The Nahargarh Biological Park lies within the sanctuary, contributing to conservation and awareness. The sanctuary’s proximity to Jaipur makes it significant for urban biodiversity conservation, where human-wildlife interactions are a growing concern. Q.

Statement 2 is not correct: Tapirs are distributed across South America, Central America, and Southeast Asia, not exclusively Asia.

Their dependence on forest ecosystems and water bodies makes them highly vulnerable to habitat loss and fragmentation. Q .
