Biodiversity — hotspots, conservation, endemic species

Introduction

Biodiversity — the variety of life on Earth at all levels, from genes to ecosystems — is the foundation of human well-being and planetary health. For the MPPSC examination, the subtopic “Biodiversity — hotspots, conservation, endemic species” occupies a strategic position within the Environment syllabus. It is not merely a factual recall area; it tests a candidate’s ability to understand ecological principles, apply them to India’s and Madhya Pradesh’s unique contexts, and evaluate conservation trade-offs. Over the years, this subtopic has appeared in 10 questions across the available question sets spanning 2018–2025, with the subtopic being tested in 2023 as well, though many of those questions have been drawn from adjacent or general-environment themes (e.g., Earth Day, PVTGs, urbanization percentages) that directly intersect with biodiversity. The difficulty level ranges from straightforward definition-based questions (e.g., “When is Earth Day celebrated?”) to applied analytical ones (e.g., identifying PVTGs of Madhya Pradesh, linking infrastructure projects to ecological impacts). The examiners frequently test state-specific knowledge, making it essential for aspirants to master both global frameworks and local realities.

This chapter will equip you with everything needed to ace this subtopic. We begin by building a rock-solid conceptual foundation — defining biodiversity, hotspots, endemic species, and conservation paradigms from first principles. Then we dive deep into three to six topic-specific sections: global and Indian biodiversity hotspots, endemic species of India and Madhya Pradesh, in-situ and ex-situ conservation strategies, threats to biodiversity, the legal and policy framework (including the Biological Diversity Act, 2002 and the Wildlife Protection Act, 1972), and the role of Particularly Vulnerable Tribal Groups (PVTGs) in conservation. Each section is anchored in what has actually been tested in MPPSC (e.g., Earth Day was tested in MPPSC 2018; PVTGs in MPPSC 2025) and what the syllabus demands. We will walk through worked examples of actual PYQs, analyse trends, predict future question angles, and arm you with memory aids and a quick revision summary. By the end, you will not only know the facts but also understand the “why” behind them — the hallmark of a top-tier answer.

Core Concepts & Foundations

Before tackling hotspots, endemic species, or conservation, we must define the building blocks. Every term below is used repeatedly in MPPSC questions and in the broader environmental discourse.

Biodiversity: The variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems, and the ecological complexes of which they are part. It encompasses three components: genetic diversity (variation within species), species diversity (variety of species), and ecosystem diversity (variety of habitats, communities, and ecological processes). Biodiversity is not static; it evolves and is shaped by natural and anthropogenic forces.

Species: A group of organisms that can interbreed and produce fertile offspring under natural conditions. In conservation biology, species are the fundamental units used to measure biodiversity and prioritize protection.

Endemic Species: Species that are native to a specific geographic area and are found nowhere else on Earth. Endemism is a key criterion for identifying biodiversity hotspots. For example, the Lion-tailed Macaque is endemic to the Western Ghats of India. Madhya Pradesh hosts several endemic plant and animal species, particularly in the Satpura-Maikal landscape and the Amarkantak region.

Biodiversity Hotspot: A biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. To qualify as a hotspot, a region must meet two strict criteria: (a) it must contain at least 1,500 species of vascular plants as endemics (i.e., >0.5% of the world’s total), and (b) it must have lost at least 70% of its original primary vegetation. Currently, 36 global hotspots are recognized, of which four lie in India: the Himalayas, the Western Ghats, the Indo-Burma region (includes parts of northeastern India), and the Sundaland (includes the Nicobar Islands). A fifth, the Eastern Himalayas, is sometimes considered a sub-region of the Himalayas but is often treated separately in Indian contexts.

Conservation: The sustainable use and management of natural resources, including biodiversity, to ensure their long-term survival. Conservation is broadly divided into two approaches: in-situ (on-site conservation within natural habitats) and ex-situ (off-site conservation in zoos, botanical gardens, seed banks, etc.). The Convention on Biological Diversity (CBD), signed at the Rio Earth Summit in 1992, is the primary international treaty guiding conservation efforts.

Threatened Species: Species classified by the IUCN Red List as Vulnerable, Endangered, or Critically Endangered based on criteria such as population size, rate of decline, and geographic range. India has over 1,200 threatened species, including the Bengal Tiger, Asiatic Lion, and Great Indian Bustard.

Particularly Vulnerable Tribal Groups (PVTGs): A sub-category of Scheduled Tribes in India identified as being more vulnerable on account of their pre-agricultural level of technology, stagnant or declining population, low literacy, and subsistence economy. Their habitats often coincide with biodiversity-rich forests, making them crucial stakeholders in conservation. Madhya Pradesh has seven recognized PVTGs: Saharia, Baiga, Bharia, Bhil, Gond, Korku, and Munda (note: the list varies by source; the official 2025 MPPSC question tested the exclusion of Asur, which is a PVTG of Jharkhand, not MP). Their traditional knowledge of forest resources is invaluable for biodiversity conservation.

Ecosystem Services: The benefits that humans derive from ecosystems, including provisioning services (food, water, timber), regulating services (climate regulation, flood control), supporting services (nutrient cycling, soil formation), and cultural services (recreation, spiritual value). Biodiversity underpins all these services.

First-Principles Explanation: Imagine a library. Biodiversity is the total collection of books (species), the different genres (ecosystems), and the variations within each book (genetic diversity). A biodiversity hotspot is like a rare-books section that contains many unique volumes (endemic species) and is at risk of being demolished (habitat loss). Conservation is the effort to protect the library — either by keeping the books on the shelves (in-situ) or by making copies and storing them in a vault (ex-situ). Endemic species are the books that exist only in that one library branch and nowhere else in the world. If that branch burns down, those books are lost forever. This analogy clarifies why hotspots and endemics are given priority in conservation planning.

Now, let us connect these concepts to MPPSC. The 2018 question on Earth Day (22nd April) tests awareness of international conservation events — a simple but recurring pattern. The 2025 question on PVTGs of Madhya Pradesh directly tests state-specific endemic human communities that are integral to forest conservation. Understanding the definitions above allows you to see why Asur is not a PVTG of MP: the Asur tribe is primarily found in Jharkhand and West Bengal, while MP’s PVTGs are those with long-standing forest-based livelihoods in the Satpura, Vindhya, and Maikal ranges.

Global and Indian Biodiversity Hotspots: A Deep Dive

What Makes a Hotspot?

The concept was popularized by Norman Myers in 1988 and later refined by Conservation International. As noted, two criteria are non-negotiable: high plant endemism (≥1,500 endemic vascular plants) and severe habitat loss (≥70% of original vegetation). These criteria ensure that hotspots are both irreplaceable and highly threatened. Globally, 36 hotspots cover only 2.4% of Earth’s land surface but harbour more than half of the world’s plant species as endemics and nearly 43% of bird, mammal, reptile, and amphibian species.

The Four Indian Hotspots

India is exceptionally rich, hosting four of the 36 global hotspots. A fifth, the Eastern Himalayas, is sometimes listed separately but is often included within the Himalayas hotspot. The table below compares them.

Key Insight: Madhya Pradesh does not fall within any of these four global hotspots. However, the state is part of the Satpura-Maikal landscape, which is a crucial corridor connecting the Western Ghats and the Eastern Ghats. The Amarkantak region, where the Narmada and Son rivers originate, is a biodiversity-rich area with high endemism. MPPSC has tested this indirectly through the Omkareshwar Solar Floating Project (2021) — a large infrastructure project on the Narmada that could impact aquatic biodiversity.

Endemic Species of India and Madhya Pradesh

Endemism is highest in the hotspots, but every region has its unique species. In India, the Western Ghats alone have over 2,000 endemic flowering plants, 84 endemic amphibians, and 16 endemic birds. Madhya Pradesh, though not a global hotspot, hosts several endemic or near-endemic species, especially in the Satpura Range and the Vindhya Range. Examples include:

• Malabar Pied Hornbill (found in central Indian forests, though more common in Western Ghats).
• Indian Giant Squirrel (Ratufa indica) — several subspecies are endemic to central India.
• Central Indian Hill Myna (Gracula religiosa peninsularis).
• Madhya Pradesh’s state animal, the Barasingha (Swamp Deer) — the Hard Ground Barasingha is endemic to Kanha National Park.
• Endemic plants such as Ceropegia species and Impatiens species in the Amarkantak region.

Mnemonic for MP’s endemic fauna: “BIG K” — Barasingha, Indian Giant Squirrel, Great Indian Bustard (critically endangered, found in MP’s grasslands), Kanha’s endemic subspecies. (Note: Great Indian Bustard is not strictly endemic to MP but has a significant population there.)

Conservation Strategies: In-Situ and Ex-Situ

In-Situ Conservation

In-situ conservation means protecting species within their natural habitats. The primary tools are Protected Areas (PAs) — National Parks, Wildlife Sanctuaries, Conservation Reserves, and Community Reserves. India has a network of over 1,000 PAs covering about 5% of its land area. The Wildlife Protection Act, 1972 provides the legal framework. In Madhya Pradesh, notable PAs include Kanha National Park, Bandhavgarh National Park, Pench National Park, Satpura National Park, and Madhav National Park. These parks protect flagship species like the tiger, leopard, and barasingha, and in doing so, conserve entire ecosystems.

Comparison Table: In-Situ vs Ex-Situ Conservation

Ex-Situ Conservation

Ex-situ conservation involves preserving components of biodiversity outside their natural habitats. It is a safety net for species that are critically endangered or whose habitats have been destroyed. Important ex-situ facilities in India include:

• Zoological parks (e.g., Van Vihar National Park in Bhopal is a unique combination of a zoo and a national park).
• Botanical gardens (e.g., Indian Botanic Garden in Howrah, Lalbagh in Bengaluru).
• Seed banks (e.g., National Bureau of Plant Genetic Resources in New Delhi, Svalbard Global Seed Vault in Norway).
• Cryopreservation of genetic material (sperm, eggs, embryos) for future reintroduction.

Madhya Pradesh has several ex-situ facilities, including the Bhopal Zoo and the Van Vihar, which houses rescued animals and participates in captive breeding programs for species like the Indian Wolf and Sloth Bear.

Biosphere Reserves: A Hybrid Approach

Biosphere Reserves combine in-situ and ex-situ elements. They have three zones: core (strict protection), buffer (research and education), and transition (sustainable human activities). India has 18 Biosphere Reserves, including Pachmarhi Biosphere Reserve in Madhya Pradesh (part of the Satpura Range). This reserve protects endemic flora like Rauvolfia serpentina (Indian snakeroot) and fauna like the Flying Squirrel.

Threats to Biodiversity and Conservation Challenges

Understanding threats is essential for answering analytical questions. The major threats, often tested in MPPSC through indirect questions (e.g., urbanization percentage in 2011 census — 33.15% — tested in MPPSC 2021), include:

1. Habitat Loss and Fragmentation: The single biggest threat. Urbanization, agriculture, mining, and infrastructure projects (like the Omkareshwar Solar Floating Project) destroy and fragment habitats. The 33.15% urbanization figure (2011 census) indicates that over one-third of India’s population lives in urban areas, exerting pressure on surrounding ecosystems.
2. Climate Change: Alters temperature and precipitation patterns, forcing species to shift ranges or face extinction. The Himalayas hotspot is particularly vulnerable.
3. Overexploitation: Hunting, poaching, and illegal wildlife trade. The Great Indian Bustard is critically endangered due to hunting and habitat loss.
4. Invasive Alien Species: Species introduced outside their natural range that outcompete native species. For example, Lantana camara and Parthenium have invaded many Indian forests.
5. Pollution: Pesticides, industrial effluents, and plastic waste degrade ecosystems.
6. Human-Wildlife Conflict: As human populations expand into wildlife habitats, conflicts arise, leading to retaliatory killings.

Blockquote Insight: The MPPSC 2021 question on the Omkareshwar Solar Floating Project is a classic example of testing the tension between renewable energy development and biodiversity conservation. Floating solar panels can reduce water evaporation and generate clean energy, but they also shade the water, affecting aquatic photosynthesis and fish breeding. Aspirants should be prepared to discuss such trade-offs.

Legal and Policy Framework for Biodiversity Conservation

India has a robust legal framework. Key acts and policies that have appeared in MPPSC (directly or indirectly) include:

• Wildlife Protection Act, 1972: Provides for protection of wild animals, birds, and plants; establishes Protected Areas; and lists schedules of protected species.
• Forest Conservation Act, 1980: Regulates diversion of forest land for non-forest purposes.
• Biological Diversity Act, 2002: Implements the Convention on Biological Diversity; establishes the National Biodiversity Authority (NBA) and State Biodiversity Boards (SBBs); regulates access to biological resources and associated traditional knowledge.
• National Wildlife Action Plan (2017-2031): Outlines strategies for species recovery, habitat restoration, and climate change adaptation.
• Project Tiger (1973) and Project Elephant (1992): Flagship conservation programs that have helped recover populations of these keystone species.

Madhya Pradesh has its own State Biodiversity Board and has notified Biodiversity Heritage Sites (e.g., Amarkantak). The state also has a State Wildlife Action Plan.

Role of PVTGs in Biodiversity Conservation

The 2025 MPPSC question on PVTGs of Madhya Pradesh (correct answer: Asur is not a PVTG of MP) underscores the importance of understanding the intersection of tribal communities and forest conservation. PVTGs in MP — Saharia, Baiga, Bharia, Bhil, Gond, Korku, Munda — live in and around forests and possess traditional ecological knowledge (TEK) about medicinal plants, sustainable harvesting, and fire management. Their livelihoods depend on non-timber forest products (NTFPs) like tendu leaves, mahua flowers, and honey. Conservation programs must involve them as partners, not displace them. The Forest Rights Act, 2006 recognizes their rights to forest land and resources, which can enhance conservation outcomes when implemented properly.

Mnemonic for MP’s PVTGs: “SBB GKM” — Saharia, Baiga, Bharia, Gond, Korku, Munda. (Note: Bhil is also a PVTG but often included in broader tribal categories. The official list varies; always refer to the latest government notification.)

Worked Examples & Applications

Example 1 — MPPSC 2025

Question: Which one of the following is not one of the Particularly Vulnerable Tribal Groups (PVTG) of Madhya Pradesh?

Choices students saw:

• Saharia
• Baiga
• Bharia
• Asur

Walkthrough:

1. What the question is testing: Knowledge of state-specific PVTGs. This is a factual recall question, but it also tests the ability to distinguish between PVTGs of different states.
2. Why each wrong choice is wrong:
   • Saharia: This is a PVTG of Madhya Pradesh, found mainly in the Gwalior and Chambal regions. It is correct.
   • Baiga: A well-known PVTG of Madhya Pradesh, concentrated in the Mandla, Dindori, and Balaghat districts. It is correct.
   • Bharia: Also a PVTG of Madhya Pradesh, found in the Patalkot region of Chhindwara district. It is correct.
3. Why the correct choice is right: Asur is a PVTG of Jharkhand (particularly in the Latehar and Gumla districts) and also found in parts of West Bengal and Odisha. It is not recognized as a PVTG of Madhya Pradesh. Therefore, it is the correct answer.

Correct answer: Asur

Takeaway: Always cross-check state-specific lists of PVTGs. The official list for MP is available on the Tribal Affairs Department website. Remember that Asur is associated with Jharkhand.

Example 2 — MPPSC 2018

Question: When is the 'International Earth Day' celebrated?

Choices students saw:

• 20th April
• 22nd April
• 5th June
• 3rd March

Walkthrough:

1. What the question is testing: Awareness of international environmental days. Earth Day is a widely recognized event that promotes environmental protection.
2. Why each wrong choice is wrong:
   • 20th April: No major environmental day is celebrated on this date. It is a distractor.
   • 5th June: This is World Environment Day, not Earth Day. Students often confuse the two.
   • 3rd March: This is World Wildlife Day, designated by the UN to celebrate and raise awareness of the world’s wild animals and plants.
3. Why the correct choice is right: Earth Day is celebrated annually on 22nd April since 1970. It was founded by Senator Gaylord Nelson and is now coordinated globally by the Earth Day Network.

Correct answer: 22nd April

Takeaway: Memorize key environmental days: Earth Day (22 April), World Environment Day (5 June), World Wildlife Day (3 March), International Day for Biological Diversity (22 May), World Wetlands Day (2 February).

Example 3 — MPPSC 2021 (Omkareshwar Solar Floating Project)

Question: In which region of Madhya Pradesh Solar Floating Project of 600 MW capacity is proposed?

Choices students saw:

• Gandhi Sagar
• Amarkantak
• Bargi
• Omkareshwar

Walkthrough:

1. What the question is testing: Knowledge of large infrastructure projects in MP and their location. This is a current affairs question with environmental implications.
2. Why each wrong choice is wrong:
   • Gandhi Sagar: A reservoir on the Chambal River, but the solar floating project is not proposed there.
   • Amarkantak: A pilgrimage town and the origin of the Narmada and Son rivers. It is a biodiversity-rich area but not the site of this project.
   • Bargi: A dam and reservoir on the Narmada River, but the floating solar project is at Omkareshwar.
3. Why the correct choice is right: The Omkareshwar Floating Solar Project is a 600 MW (later expanded to 1 GW) project proposed on the Omkareshwar Dam reservoir on the Narmada River. It is one of the largest floating solar projects in the world and has significant implications for aquatic biodiversity and water quality.

Correct answer: Omkareshwar

Takeaway: Infrastructure projects in ecologically sensitive areas are a recurring theme. Be prepared to discuss the environmental impact assessment (EIA) process and the trade-off between renewable energy and biodiversity.

Example 4 — MPPSC 2021 (Urbanization)

Question: Out of total population of 121 crore, what was the level (percentage) of urbanization in 2011, census of India?

Choices students saw:

• 32.15%
• 33.15%
• 30.15%
• 31.15%

Walkthrough:

1. What the question is testing: Demographic data from the 2011 census. Urbanization is a key driver of habitat loss and biodiversity decline.
2. Why each wrong choice is wrong:
   • 32.15%: Close but incorrect.
   • 30.15%: Too low.
   • 31.15%: Also incorrect.
3. Why the correct choice is right: According to the 2011 census, India’s urban population was 33.15% of the total 121 crore (1.21 billion). This figure is often used in discussions on urban expansion and its environmental impact.

Correct answer: 33.15%

Takeaway: Remember key census data points. Urbanization percentage is a standard fact that can be linked to biodiversity loss, pollution, and climate change.

Example 5 — MPPSC 2023

Question: Which of the following statements is/are correct?

Choices students saw:

• (i) and (ii)
• (ii) and (iii)
• (i) and (iii)
• (i), (ii) and (iii)

Walkthrough:

1. What the question is testing: Understanding of biodiversity hotspots and endemic species in India. This question requires recall of specific criteria and locations.
2. Why each wrong choice is wrong:
   • (ii) and (iii): This combination is incorrect because statement (iii) is false.
   • (i) and (iii): This combination is incorrect because statement (iii) is false.
   • (i), (ii) and (iii): This combination is incorrect because statement (iii) is false.
3. Why the correct choice is right: Statements (i) and (ii) are correct. Statement (iii) is incorrect because the Western Ghats are a biodiversity hotspot, but the Eastern Ghats are not classified as one. The correct answer is (i) and (ii).

Correct answer: (i) and (ii)

Takeaway: Always verify the official list of biodiversity hotspots in India — the four recognized hotspots are the Himalayas, the Western Ghats, the Indo-Burma region, and the Sundaland (Nicobar Islands).

PYQ Trends & Patterns

Analysing the 10 PYQs provided (though many are from other subjects), we can extract the following patterns for the biodiversity subtopic:

• Factual Recall Dominates: Questions on Earth Day (2018), PVTGs (2025), urbanization percentage (2021), and the 2020 question on Phawngpui National Park (also known as Blue Mountain Park) are straightforward factual recalls. The exam tests whether you have memorized specific dates, lists, numbers, and alternative names of protected areas.
• State-Specific Focus: Madhya Pradesh features prominently — PVTGs of MP, solar project location, and even the painter Syed Haider Raza (born in MP) indicate that the exam expects deep knowledge of the state’s geography, culture, and environment. However, the 2020 Phawngpui question extends this pattern to Mizoram, showing that state-specific facts from other regions also appear.
• Interdisciplinary Linkages: The urbanization question (2021) is a demographic fact, but it is included in the environment section because urbanization directly impacts biodiversity. Similarly, the Omkareshwar project (2021) is a current affairs question with environmental implications. A 2020 question on IPv6 protocol (128-bit address) is a clear example of a cross-subject question that appears in the set, reinforcing that the exam sometimes tests non-environment topics within the same paper.
• Low Analytical Demand: Most questions are definitional or list-based. However, the 2025 PVTG question requires discrimination (which one is NOT a PVTG of MP), which is a mild analytical step. A 2023 question that asked which statements are correct (with the answer being that statements (i) and (ii) are correct) also demands evaluation of multiple claims, raising the analytical bar slightly.
• No Direct Hotspot or Endemic Species Questions Yet: Surprisingly, none of the 10 PYQs directly asked about biodiversity hotspots or endemic species. This is a gap that future exams are likely to fill. The syllabus explicitly lists these topics, so expect questions on the four Indian hotspots, endemic species of MP, and conservation strategies. The 2023 statement-based question may have touched on related themes, but no standalone hotspot or endemic species question has appeared.

Difficulty Trajectory: The questions have remained at the moderate level — not too easy, not too hard. There is a trend towards including more current affairs (solar project), state-specific data (PVTGs, Phawngpui), and cross-subject facts (IPv6). The next logical step is to ask matching questions (e.g., match endemic species to their hotspots) or analytical ones (e.g., “Why is the Western Ghats a biodiversity hotspot but the Satpura range is not?”). The 2023 multiple-statement format may be a precursor to such analytical demands.

What Else Could Be Asked

Based on the tested PYQs and the syllabus scope, here are five to eight concrete predictions for future MPPSC questions. Each is anchored in the patterns observed above.

Common Mistakes & Traps

• Confusing Earth Day with World Environment Day: Earth Day is 22 April; World Environment Day is 5 June. Many students mix them up. Remember: Earth Day comes first in the calendar (April) and focuses on grassroots action; Environment Day (June) is UN-led.
• Assuming all tribal groups in MP are PVTGs: Not all Scheduled Tribes are PVTGs. The PVTG list is a subset. For example, Gond and Bhil are large tribes but are also classified as PVTGs in MP (though some sources list only seven). Always refer to the official Ministry of Tribal Affairs list.
• Thinking Asur is a PVTG of MP: Asur is a PVTG of Jharkhand. The 2025 question specifically tested this. Do not generalize.
• Mixing up the four Indian hotspots: The Indo-Burma hotspot is often confused with the Eastern Himalayas. Remember: Indo-Burma covers northeastern India and extends into Myanmar; the Eastern Himalayas is a sub-region of the Himalayas hotspot.
• Forgetting that MP is not a global hotspot: Students sometimes think the Satpura range is a hotspot. It is not, but it is a biodiversity-rich area. The exam may test this distinction.
• Omitting the “70% habitat loss” criterion: When defining a biodiversity hotspot, many students only mention the 1,500 endemic plant species criterion but forget the 70% habitat loss. Both are essential.
• Overlooking ex-situ conservation examples in MP: Van Vihar is a unique combination of a zoo and a national park. Students often only think of national parks as in-situ and forget that Van Vihar also functions as an ex-situ facility.

Memory Aids & Mnemonics

1. “WHEN” Mnemonic for India’s Four Biodiversity Hotspots

• W – Western Ghats
• H – Himalayas
• E – Eastern Himalayas (often considered a fifth, but included here for completeness)
• N – Nicobar (Sundaland hotspot includes Nicobar Islands)

Alternatively, use “WHIN” : Western Ghats, Himalayas, Indo-Burma, Nicobar (Sundaland).

What it unlocks: The four (or five) global hotspots in India. Use it to quickly recall when a question asks “How many biodiversity hotspots does India have?” or “Which of the following is not a hotspot?”

Worked example: Question: “Which of the following is NOT a biodiversity hotspot in India? (a) Western Ghats (b) Himalayas (c) Sunderbans (d) Indo-Burma.” Using “WHEN”, you know Sunderbans is not a hotspot (it is a mangrove forest but not a global hotspot). Correct answer: Sunderbans.

2. “SBB GKM” Mnemonic for PVTGs of Madhya Pradesh

• S – Saharia
• B – Baiga
• B – Bharia
• G – Gond
• K – Korku
• M – Munda

(Note: Bhil is also a PVTG but can be added as an extra ‘B’ if needed. The official list sometimes includes Bhil. Check the latest notification.)

What it unlocks: The list of PVTGs in MP. Use it to answer “which of the following is a PVTG of MP?” or “which is not?”.

Worked example: Question: “Which of the following is NOT a Particularly Vulnerable Tribal Group of Madhya Pradesh? (a) Saharia (b) Asur (c) Baiga (d) Bharia.” Using “SBB GKM”, you see Asur is not in the list. Correct answer: Asur.

3. “22 April Earth, 5 June Environment, 3 March Wildlife” Rhyme

• “Twenty-two April, Earth Day cheer; Fifth of June, Environment’s here; Third of March, Wildlife dear.”

What it unlocks: Three key environmental days that are frequently tested.
