Q151. Match the items in List I with those in List II and select the correct answer using the codes given below:
Conservation Milestone
Associated Year/Event in Rajasthan
A. Project Tiger launched in Ranthambore
i. 1985
B. Keoladeo Ghana declared a UNESCO World Heritage Site
ii. 1973-74
C. Chinkara designated as State Animal
iii. 1983
D. Khejri designated as State Tree
iv. 1981
Explanation
Key conservation milestones in Rajasthan occurred over several decades. Project Tiger was launched at Ranthambore in 1973-74. Keoladeo Ghana National Park received its UNESCO World Heritage status in 1985. The state officially designated the Chinkara as the State Animal in 1981, and the Khejri tree was recognized as the State Tree in 1983, formalizing the protection of these symbols.

Q152. Which of the following is correctly paired regarding the dominant flora and its primary utility in Rajasthan?
Explanation
In Rajasthan, different tree species serve specific economic roles. The Tendu tree is particularly important because its leaves are harvested and used as wrappers for traditional bidis, providing a significant source of seasonal income for tribal communities. The other options are incorrect, as Babool is a thorn tree, Rohida is for timber, and Salar is primarily used for the packing and paper industry.

Q153. In which year was the Ranthambore National Park initially brought under the umbrella of ‘Project Tiger’?
Explanation
Ranthambore National Park was among the first nine tiger reserves established across India when ‘Project Tiger’ was launched in 1973. This initiative was designed to protect the declining population of Bengal tigers and their habitats. Since then, Ranthambore has become one of the most famous tiger reserves in the world, known for its successful conservation efforts and high tiger density.

Q154. Which of the following is not considered a major threat to biodiversity and conservation in Rajasthan?
Explanation
Orans (sacred groves) and Gochars (community pastures) are traditional land management systems that have actually protected Rajasthan’s biodiversity for centuries. These areas are governed by community rules that prohibit tree cutting and overexploitation. In contrast, threats like habitat fragmentation from roads, illegal poaching, and the erratic rainfall patterns caused by climate change significantly endanger the state’s natural flora and fauna.

Q155. Identify the incorrect statement regarding the biodiversity hotspots and challenges in Rajasthan.
Explanation
Contrary to common belief, the Thar Desert is one of the most populated and biologically diverse deserts in the world. It hosts a wide variety of flora and fauna that have evolved unique survival strategies. While challenges like invasive species and grazing pressures exist, the desert’s biodiversity index is relatively high compared to other global deserts, making it an ecological treasure rather than a barren wasteland.

Q156. What is the cause and effect relationship associated with the widespread planting of Prosopis juliflora (Vilayati Babool) in Rajasthan?
Explanation
The introduction of Prosopis juliflora, known locally as Vilayati Babool, was intended for greening arid areas. However, it became a highly invasive species. It competes aggressively with native plants for limited water and nutrients, eventually suppressing local flora. Its presence has altered habitats, as it does not support the same diversity of native wildlife or provide high-quality fodder compared to indigenous species like Khejri.

Q157. Before being upgraded and renamed as Keoladeo Ghana National Park, by what popular name was this wildlife sanctuary globally known?
Explanation
Before it was upgraded to a National Park and renamed Keoladeo Ghana National Park, the area was globally recognized as the Bharatpur Bird Sanctuary. The name "Ghana" refers to the thick forest cover that once characterized this region. It has long been a destination for birdwatchers and scientists due to the incredible variety and density of avian species that congregate in its wetlands.

Q158. In the context of Rajasthan’s conservation efforts, which specific designation highlights Keoladeo National Park’s international importance as a wetland habitat?
Explanation
The "Ramsar Site" designation specifically highlights Keoladeo National Park’s international importance as a wetland habitat. The Ramsar Convention is an international treaty for the conservation and sustainable use of wetlands. Keoladeo was one of the first sites in India to be recognized for its role in supporting migratory waterbirds and maintaining a healthy, biodiverse wetland ecosystem in an arid state.

Q159. Identify the correct statement regarding the Desert Fox, an important fauna species of Rajasthan.
Explanation
The Desert Fox is a key fauna species of Rajasthan, primarily found in the arid and semi-arid scrublands of the Thar Desert. It is a highly adaptable carnivore, preying on small mammals like rodents, as well as insects and birds. Unlike animals that require perennial water, the desert fox is well-adapted to survive in dry environments with limited water sources.

Q160. A botanist observes a plant in Rajasthan that exhibits a massive network of shallow roots, fleshy stems, and a thick waxy cuticle. To which ecological category does this plant most likely belong?
Explanation
A plant with a massive network of shallow roots for quick water absorption, fleshy stems for storage, and a thick waxy cuticle to prevent evaporation is a classic Xerophyte. These physiological and structural features are essential for survival in environments where water is scarce and evaporation rates are high, such as the desert and semi-arid regions found throughout most of Rajasthan.

Key facts from Rajasthan Geography
The RPSC syllabus lists Rajasthan’s location, extent and physiography, rivers and lakes, climate, vegetation, biodiversity, soils, agriculture, livestock, irrigation, population, urbanisation and tribes.
Many questions ask for a number or a name: the area of the State, a district’s density, the length of a canal, the home district of a mine.
Rajasthan is the biggest State of India by area, and several chapters test the contrast between the arid west and the humid south-east.
Minerals, irrigation and wildlife are the chapters with the most name-based questions, so keep a list of districts and projects.
Population questions use Census 2011 figures.
