Which one of the following is located in the Bastar region?

1. Protected Area Framework: WLPA 1972 (basic)

Welcome to your first step in mastering India's environmental geography! To understand why a specific forest or park is famous, we must first understand the legal 'shield' that protects it. The Wildlife (Protection) Act (WLPA) of 1972 is the bedrock of conservation in India. Before this act, 'Forests' and 'Wildlife' were strictly State subjects, meaning the Central Parliament had limited power to intervene. The WLPA 1972 changed the game by providing a uniform national legal framework for protecting wild animals, birds, and plants Shankar IAS, Protected Area Network, p.211. Under this Act, the government classifies protected areas into different categories, most notably National Parks (NP) and Wildlife Sanctuaries (WLS). While they might seem similar, they have distinct legal nuances. A National Park typically enjoys a higher degree of protection where almost all human activities, like livestock grazing, are strictly prohibited. In contrast, a Wildlife Sanctuary might allow limited human interaction and regulated grazing with permission Majid Hussain, Biodiversity, p.32. Additionally, a Sanctuary can be created to protect a specific species (like a bird sanctuary), whereas a National Park focuses on the entire ecosystem and is not usually species-centric Shankar IAS, Protected Area Network, p.213.

Feature	National Park	Wildlife Sanctuary
Focus	Entire ecosystem (Flora, fauna, landscape)	Can be specific to a particular species
Human Activity	Strictly prohibited (No grazing)	Regulated/limited human interaction allowed
Protection Level	Very High	High (but less than National Parks)

Historically, this legislation evolved from the Wild Birds Protection Act of 1887. By 1991, amendments to the WLPA significantly centralized power, making it much harder for State Governments to declare animals as 'vermin' (pests that can be hunted) without Central oversight Shankar IAS, Protected Area Network, p.212. The animals themselves are listed in various Schedules; those in Schedule I receive the absolute highest legal protection and the harshest penalties for poaching Shankar IAS, Schedule Animals of WPA 1972, p.171.

2. Physical Geography of the Peninsular Plateau (basic)

The Peninsular Plateau is the oldest and most stable landmass of India. Imagine a massive, irregular triangle rising from the river plains to an elevation of 600–900 meters. This region is not a single flat block but a series of patland plateaus (table-like highlands), including the Malwa, Chotanagpur, and Deccan plateaus INDIA PHYSICAL ENVIRONMENT, Geography Class XI (NCERT 2025 ed.), Structure and Physiography, p.12. Its boundaries are defined by the Delhi Ridge in the northwest, the Rajmahal Hills in the east, the Gir Range in the west, and the Cardamom Hills in the south. Interestingly, the plateau extends even into the northeast as the Meghalaya and Karbi-Anglong Plateau, though it is separated from the main block by a geological fault CONTEMPORARY INDIA-I, Geography, Class IX . NCERT(Revised ed 2025), Physical Features of India, p.12.

One of the most striking features of this plateau is the Deccan Trap, a region of black soil formed by ancient volcanic activity. These igneous rocks have weathered over millions of years to create fertile soil perfect for cotton cultivation CONTEMPORARY INDIA-I, Geography, Class IX . NCERT(Revised ed 2025), Physical Features of India, p.13. The plateau generally slopes from west to east, which is why major rivers like the Godavari, Krishna, and Kaveri flow toward the Bay of Bengal. However, the plateau is also divided into distinct cultural and physical zones, such as Dandakaranya. This undulating region spans parts of Chhattisgarh, Odisha, and Andhra Pradesh; it is famous for its rich iron-ore deposits in the Bailadila Range and is drained by rivers like the Indravati, a key tributary of the Godavari Geography of India, Majid Husain, Physiography, p.57.

To the edges of the plateau lie the Ghats. While the Western Ghats are continuous and higher, the Eastern Ghats are discontinuous and eroded by rivers. In the heart of the plateau, particularly in the Bastar region of Chhattisgarh, the landscape transitions into dense forests and river basins, where the Indravati river winds across the plateau from east to west India and the Contemporary World - I, History-Class IX . NCERT(Revised ed 2025), Forest Society and Colonialism, p.90.

Feature	Description
Rock Type	Ancient Archaean rocks (Granite and Gneiss) and volcanic Igneous rocks.
General Slope	West to East (gentle gradient).
Key Sub-regions	Malwa, Deccan Trap, Chotanagpur, and Dandakaranya.

3. Major River Systems of Central India (intermediate)

To understand the geography of Central India, we must look at the Peninsular Drainage System, which is older than the Himalayan one. The drainage here is largely dictated by the tilt of the Indian plateau from west to east, though tectonic features like rift valleys create fascinating exceptions. The Godavari, often called the Dakshin Ganga, is the titan of this region. Rising from the Trimbak Plateau near Nasik, it is the largest peninsular river, stretching 1,465 km. Its basin is a complex web touching Maharashtra, Madhya Pradesh, Chhattisgarh, and Odisha. Key tributaries like the Indravati and Sabari are unique because they originate on the western slopes of the Eastern Ghats but flow east and southeast to join the Godavari, specifically draining the rugged Bastar Plateau Geography of India by Majid Husain, The Drainage System of India, p.21. Moving eastward, the Mahanadi serves as the lifeline for Chhattisgarh and Odisha. It originates in the Dandakaranya Plateau near Raipur. Unlike the Godavari, which carves through the Western Ghats, the Mahanadi's journey is defined by the highland regions of Central India, receiving tributaries like the Seonath, Hasdeo, and Tel Geography of India by Majid Husain, The Drainage System of India, p.20. This region forms a crucial ecological bridge between the central highlands and the eastern coastal plains. Finally, we must distinguish the West-Flowing Rivers, primarily the Narmada and Tapi. The Narmada is particularly significant as it rises from the Amarkantak Plateau and flows through a deep rift valley between the Vindhya and Satpura ranges. This westward flow is a geographical anomaly caused by faults in the earth's crust, meaning these rivers do not form deltas like their eastern counterparts but instead create estuaries NCERT Class XI, India Physical Environment, p.23.

4. Project Tiger and Tiger Reserves in India (intermediate)

To understand tiger conservation in India, we must start with Project Tiger, a flagship initiative launched in 1973. Originally, it aimed to halt the rapid decline of tiger populations by securing dedicated habitats. Over the decades, this project has evolved from a simple scheme into a sophisticated administrative framework. Today, Tiger Reserves are governed by the National Tiger Conservation Authority (NTCA), a statutory body established under the 2006 amendment to the Wildlife (Protection) Act, 1972 Shankar IAS Academy, Conservation Efforts, p.228. Unlike many other protected areas, a Tiger Reserve is specifically notified by the State Government, but only after receiving a formal recommendation from the NTCA Shankar IAS Academy, Conservation Efforts, p.227.

One of the most critical aspects of a Tiger Reserve is its zoning strategy. Each reserve is divided into two distinct parts to balance conservation with human needs:

Zone Type	Description & Purpose	Allowed Activities
Core Area	Also known as Critical Tiger Habitat; it is the strictly protected heart of the reserve.	Strictly regulated; minimal human interference to ensure tiger breeding.
Buffer Zone	The peripheral area surrounding the core, designed to provide extra protection and dispersal space Shankar IAS Academy, Conservation Efforts, p.227.	Limited tourism, research, sustainable grazing, and collection of minor forest produce Shankar IAS Academy, Protected Area Network, p.220.

Geographically, India currently hosts over 50 Tiger Reserves across 18 states. For example, in Chhattisgarh, major reserves include Indravati (located in the Bastar/Bijapur region), Udanti-Sitanadi, and Achanakmar. In contrast, other states have their own landmarks, such as Bandipur in Karnataka or Sariska in Rajasthan Shankar IAS Academy, Environment Issues and Health Effects, p.431. Understanding this distribution is key to mastering the environmental map of India.

5. Regional Distribution of Bio-Geographic Zones (intermediate)

To understand the distribution of environmental sites in India, we must look at the country through the lens of Bio-geographic Zones. India is divided into ten distinct zones based on climate, soil, and biodiversity. The distribution of our National Parks and Wildlife Sanctuaries isn't random; it follows the logic of these zones. For instance, the Western Ghats (or the Sahyadri) represent one of the world's 'hottest hotspots' of biodiversity, stretching 1,600 km from the Tapi River in Gujarat down to Kanyakumari Geography of India, Natural Vegetation and National Parks, p.55. This region spans six states—Gujarat, Maharashtra, Goa, Karnataka, Tamil Nadu, and Kerala—and is home to iconic sites like Silent Valley and Kudremukh Geography of India, Natural Vegetation and National Parks, p.56.

Moving inland, the Deccan Peninsula is the largest bio-geographic zone, covering the central and southern plateaus. Within this zone, specific sub-regions like the Bastar forest landscape in Chhattisgarh or the Vindhya-Satpura ranges in Madhya Pradesh host distinct ecosystems. For example, while Bandhavgarh National Park is a jewel of the Madhya Pradesh highlands, Indravati National Park is the defining protected area of the southern Bastar region in Chhattisgarh, named after the Indravati River. This regional specificity is crucial because a park’s ecology is inseparable from its local geography; you wouldn't find the tropical evergreen species of the Western Ghats in the moist deciduous forests of Central India.

Region/Zone	Key Geography	Representative States
Western Ghats	Mountainous, high rainfall, 'Hottest Hotspot'	Kerala, Karnataka, Maharashtra, etc.
Deccan Peninsula	Semi-arid to moist deciduous, plateau terrain	Madhya Pradesh, Chhattisgarh, Telangana
Himalayas	High altitude, alpine to sub-tropical forests	Uttarakhand, Himachal Pradesh, Sikkim

Understanding these boundaries helps us categorize sites accurately. For example, while Rajaji National Park sits in the Shivalik foothills of the Himalayas (Uttarakhand), Dandeli is firmly rooted in the Western Ghats of Karnataka Environment, Protected Area Network, p.223. Recognizing which state and bio-geographic province a site belongs to is the 'secret sauce' for solving complex environmental mapping questions in the UPSC CSE.

6. The Environmental Landscape of Chhattisgarh (exam-level)

Chhattisgarh, often referred to as the 'Green Heart of India,' boasts a forest cover of approximately 44%, making its environmental landscape one of the most significant in the Deccan Plateau region. The state's geography is characterized by the Maikal Hills, the Chhota Nagpur Plateau, and the Bastar Plateau, each hosting unique ecosystems. The environmental health of this state is anchored by three primary National Parks: Indravati, Kanger Valley, and Sanjay National Park. While these areas share the tropical moist and dry deciduous forest types, their topographical positioning leads to distinct biodiversity profiles.

The southern Bastar region is perhaps the most ecologically vibrant. Here, Indravati National Park (established in 1981 and later a Tiger Reserve) serves as a critical sanctuary for the endangered Wild Water Buffalo (Bubalus arnee), which is also the State Animal of Chhattisgarh. The park is named after the Indravati River, which forms its northern boundary Environment and Ecology, Majid Hussain, Chapter 4: BIODIVERSITY, p.40. Nearby, the Kanger Valley National Park is famous for its hilly terrain, limestone caves (such as Kutumsar), and the Bastar Hill Myna. This park, established around 1982-83, is a prime example of the biodiversity found in the eastern part of the Dandakaranya region Geography of India, Majid Husain, Chapter 5: Natural Vegetation and National Parks, p.43.

In the northern reaches of the state lies Sanjay National Park. It is essential to distinguish this from Sanjay Gandhi National Park in Maharashtra. The Sanjay National Park in Chhattisgarh (formerly part of a larger park in Madhya Pradesh) is a vital corridor for migratory elephants and serves as a habitat for panthers, sloth bears, and various species of deer Environment and Ecology, Majid Hussain, Chapter 4: BIODIVERSITY, p.41. Understanding the location of these parks is crucial for UPSC aspirants, as they are often confused with neighboring parks like Bandhavgarh (Madhya Pradesh) or Simlipal (Odisha).

National Park	Region/Location	Key Feature/Species
Indravati	Bijapur (Bastar)	Wild Water Buffalo, Tiger Reserve
Kanger Valley	Jagdalpur (Bastar)	Limestone Caves, Hill Myna
Sanjay	Koriya/Surajpur (North CG)	Elephant Corridor, Sloth Bear

7. Key National Parks Comparison: Locations & Biomes (exam-level)

When preparing for the UPSC, it is vital to move beyond rote memorization of names and instead group National Parks by their biogeographic zones and regional geography. This approach helps you understand why certain species thrive in specific parks. For instance, the Central Indian landscape, comprising states like Madhya Pradesh and Chhattisgarh, is characterized by tropical deciduous forests. Within this region, the Bastar plateau in southern Chhattisgarh is a distinct ecological zone. It is home to the Indravati National Park, named after the Indravati River, which serves as a critical habitat for the endangered Wild Water Buffalo Geography of India, Natural Vegetation and National Parks, p. 43.

To distinguish between parks that may seem similar, we must look at their specific administrative and topographical contexts. While Bandhavgarh and Kanha are flagship parks of Madhya Pradesh known for high tiger densities Geography of India, Natural Vegetation and National Parks, p. 43, they are geographically separated from the Bastar region. Similarly, the Western Ghats of Karnataka host the Dandeli-Anshi complex, which features a completely different biome of dense evergreen and semi-evergreen forests, drastically different from the dry and moist deciduous woods of Central India Environment, Environment Issues and Health Effects, p. 431.

The following table compares key parks to help you visualize their unique regional settings:

National Park	State/Region	Key Ecological Feature
Indravati	Chhattisgarh (Bastar)	Indravati River; Wild Water Buffalo habitat
Rajaji	Uttarakhand (Shivaliks)	Transition zone between Himalayas and Gangetic Plains
Namdapha	Arunachal Pradesh	High altitude variation; Clouded Leopard Environment and Ecology, BIODIVERSITY, p.18
Keibul Lamjao	Manipur	Floating islands (Phumdis); Sangai Deer Environment and Ecology, BIODIVERSITY, p.18

Understanding these locations is not just about geography; it is about the biome. A park in the Western Ghats (like Silent Valley) will have high rainfall and orchids, whereas a park in the Shivaliks (like Rajaji) will be dominated by Sal forests and elephant corridors. Always try to link the state, the specific mountain range/river, and the flagship species together.

8. Solving the Original PYQ (exam-level)

Now that you have mastered the physiographic divisions of India and the distribution of its protected areas, this question serves as a perfect test of your ability to overlay those two layers of knowledge. The Bastar region is not just a political boundary but a distinct geographical unit in southern Chhattisgarh, defined by the Dandakaranya plateau and the Indravati River basin. To arrive at the correct answer, you must transition from simply knowing 'which park is in which state' to understanding the regional landscape where these conservation zones are situated.

By applying the elimination technique, you can systematically filter out the distractors. Bandhavgarh National Park is located in the Vindhyan hills of Madhya Pradesh, while Rajaji National Park is nestled in the Shivalik range of Uttarakhand. Dandeli Sanctuary is a common trap because its name sounds similar to regional terms in central India, but it is actually located in the Western Ghats of Karnataka. This leaves Indravati National Park, which, as noted in Geography of India by Majid Husain, is the only major reserve directly situated within the Bastar forest complex, taking its name from the river that forms its northern boundary.

UPSC frequently uses regional nomenclature (like Bastar, Malwa, or Saurashtra) instead of state names to test your depth of spatial visualization. A common pitfall is memorizing parks in isolation; however, as explained in Environment and Ecology by Majid Hussain, the most effective way to approach these questions is to link the river systems to the parks. Recognizing that the Indravati River is the lifeline of the Bastar district makes Option (D) the logical and inevitable choice.
