Biodiversity and Conservation in India

Introduction

India is one of the 17 mega-diverse countries in the world, hosting approximately 7--8% of all recorded species globally despite occupying only 2.4% of the world's land area. Four of the world's 36 biodiversity hotspots lie partly or wholly within Indian territory. Conservation of this biological wealth is governed by a robust framework of domestic legislation and international conventions.

Biodiversity Hotspots in India

A biodiversity hotspot must contain at least 1,500 endemic vascular plant species and must have lost at least 70% of its primary vegetation. Conservation International recognises 36 global hotspots; India hosts four.

Common Mistake: Students often confuse the criteria for biodiversity hotspots. Both conditions must be met simultaneously -- at least 1,500 endemic vascular plants AND at least 70% habitat loss. High biodiversity alone does not qualify a region as a hotspot; the threat element (habitat loss) is equally essential. UPSC has tested this distinction.

IUCN Red List Categories

The International Union for Conservation of Nature (IUCN) classifies species into the following threat categories:

Key Indian Species and Their IUCN Status

Protected Areas in India

National Parks

India has over 100 national parks covering approximately 44,403 sq km (about 1.35% of the country's geographical area). Key national parks include:

Wildlife Sanctuaries

India has over 560 wildlife sanctuaries. Unlike national parks, limited human activities (grazing, timber collection) may be permitted in sanctuaries with the Chief Wildlife Warden's approval.

Key distinction: National Parks vs Wildlife Sanctuaries -- In a National Park, no human activity is permitted (no grazing, no forestry). In a Wildlife Sanctuary, certain activities like grazing may be allowed with the Chief Wildlife Warden's permission. Also, a Sanctuary can be upgraded to a National Park, but not vice versa. UPSC Prelims frequently tests this difference.

Tiger Reserves and Project Tiger

Project Tiger was launched on 1 April 1973 by the Government of India to protect the Bengal Tiger and its habitat. The National Tiger Conservation Authority (NTCA) oversees Project Tiger.

Important Tiger Reserves

Biosphere Reserves

India has 18 biosphere reserves, of which 13 are recognised under UNESCO's Man and the Biosphere (MAB) Programme (as of 2025, following the inclusion of Cold Desert Biosphere Reserve, Himachal Pradesh).

Ramsar Sites (Wetlands of International Importance)

India became a signatory to the Ramsar Convention in 1982. As of April 2026, India has 99 Ramsar Sites, making it the country with the third-highest number of Ramsar sites globally (after the United Kingdom and Mexico).

Key Ramsar Sites

Environmental Legislation in India

Schedules Under Wildlife (Protection) Act (Post-2022 Amendment)

International Conventions

Exam Tip: Do not confuse CITES Appendices with WPA Schedules. CITES has 3 Appendices (I = trade ban, II = regulated trade, III = voluntary listing by a country). WPA has 4 Schedules (post-2022 amendment, reduced from 6). CITES is an international treaty; WPA is domestic law. Both protect species but operate at different levels. This overlap is a Prelims favourite.

Kunming-Montreal Global Biodiversity Framework (GBF), 2022

Adopted at CBD COP-15, this landmark framework sets 4 goals and 23 targets for 2030, including the "30x30" target -- protecting 30% of the world's land and ocean areas by 2030.

Recent Developments (2024–2026)

CBD COP16 Cali 2024 — Biodiversity Milestones and India's NBSAP

The 16th Conference of the Parties (COP16) to the Convention on Biological Diversity (CBD) was held from 21 October to 1 November 2024 in Cali, Colombia. India was among the 42 countries that submitted updated National Biodiversity Strategies and Action Plans (NBSAPs) aligned with the Kunming-Montreal Global Biodiversity Framework (KMGBF), adopted at COP15 in December 2022.

A landmark outcome of COP16 was the establishment of the "Cali Fund" — a new benefit-sharing mechanism for Digital Sequence Information (DSI) from genetic resources. India played a key role in shaping the final text, advocating for sovereign rights over genetic data. Countries also agreed to create a permanent subsidiary body for Indigenous Peoples and Local Communities (IPLCs), allowing them to participate directly in biodiversity governance — a first for the CBD.

However, COP16 was unable to finalise a strategy for mobilising $200 billion per year by 2030 for biodiversity implementation, raising concerns about the KMGBF's financial architecture. Only approximately $407 million was pledged to the interim funding mechanism, far short of requirements.

UPSC angle: COP16 outcomes — Cali Fund, NBSAP submissions, 30×30 target, and IPLCs — are high-priority Prelims and Mains topics; India's active role at biodiversity negotiations reflects GS-2 international relations themes.

IUCN Red List 2024 — Indian Species Updates

The IUCN Red List 2024 update confirmed India's Great Indian Bustard (GIB) remains Critically Endangered with fewer than 150 individuals remaining in the wild, primarily in Rajasthan and Gujarat. Despite breeding programmes and habitat management, the species continues to face threats from power line collisions, habitat conversion, and predation pressure. The Supreme Court of India in 2024 upheld Underground Cable orders in high-voltage transmission lines in GIB habitats.

The cheetah reintroduction programme at Kuno National Park (MP) has faced challenges: by September 2024, all surviving 12 adult cheetahs and 12 cubs were confined to protective enclosures (not free-ranging in the wild) following high mortality rates. 49 cubs have been born in captivity/semi-captivity at Kuno since 2023, of which 37 survive. The first recorded cheetah birth in the wild at Kuno (by an Indian-born female) was reported in April 2026 — a significant milestone. NTCA is evaluating expansion to Gandhi Sagar Sanctuary for future phases.

India's total count of protected areas stands at 987 (covering ~5.3% of geographic area), with 58 Tiger Reserves covering 84,500 sq km as of 2025.

UPSC angle: GIB, cheetah reintroduction, IUCN categories, and the 30×30 target are perennial Prelims facts; Mains may ask about challenges in the cheetah reintroduction programme or GIB conservation strategy.

Kunming-Montreal Global Biodiversity Framework — 30×30 Target Progress

The KMGBF's "30×30" goal — conserving 30% of Earth's land and oceans by 2030 — is the central global biodiversity commitment. A 2024 progress assessment found that approximately 17% of the world's land and 8% of ocean areas were formally protected, far below the 30% target. The framework also includes Target 3 on ecosystem restoration, Target 12 on increasing green urban spaces, and Target 16 on reducing harmful subsidies by at least $500 billion annually.

India's protected area network covers approximately 5.3% of land, well below the 30% target. However, India argues for counting "Other Effective Conservation Measures" (OECMs) — including community reserves, sacred groves, and agroforestry landscapes — to enhance effective coverage. India's NBSAP 2024 commits to strengthening community-based conservation and integrating biodiversity into 14 key sectors.

UPSC angle: 30×30 target, OECMs, KMGBF structure, and India's protected area percentage are direct Prelims data points; Mains GS-3 essays may ask to evaluate India's biodiversity governance vis-à-vis global frameworks.

India's Forest Cover 2023 — ISFR Key Data

The India State of Forest Report (ISFR) 2023 released by the Forest Survey of India reported total forest cover of 7,15,343 sq km (21.76% of geographic area), with total forest and tree cover at 8,27,357 sq km (25.17%). The national target remains 33% (as in the National Forest Policy 1988).

Mangrove cover increased to 4,992 sq km, and total carbon stock in India's forests reached 7,285.5 million tonnes. Top states for forest cover gain: Chhattisgarh (+684 sq km), Uttar Pradesh (+559 sq km), and Odisha (+559 sq km).

UPSC angle: ISFR 2023 data — forest cover percentage, mangrove area, carbon stock — is high-yield for Prelims 2024–25; the gap between 21.76% and the 33% target is a Mains discussion point.

First Wild Cheetah Birth in India — F1 Generation Milestone at Kuno (April 2026)

On 11 April 2026, an Indian-born female cheetah (daughter of Gamini, a South African cheetah) gave birth to four cubs in the wild at Kuno National Park, Madhya Pradesh — the first recorded wild birth of cheetahs born in India since the reintroduction began in September 2022. The mother, 25 months old, represents the F1 generation (first generation born in the host country); her reaching reproductive maturity and successfully whelping in a natural environment is the foundational criterion for assessing whether the reintroduction is biologically viable.

India's cheetah total rose to 57 following this birth. A total of 49 cubs have been born in 11 litters at Kuno since 2023, of which 37 survive. The successful wild birth counters concerns arising from the high adult mortality rate (several adult translocated cheetahs died from injuries, septicaemia, and radio-collar complications in 2023–24). MoEFCC Minister Bhupender Yadav called it "a historic moment in India's cheetah conservation journey."

UPSC angle: F1 generation wild birth (April 2026, Kuno NP), India's cheetah count (57), distinction between captive/semi-wild births and first wild birth, and biodiversity conservation success metrics are Prelims 2026 content and a Mains GS-3 conservation case study.

Vocabulary

Biodiversity

• Pronunciation: /ˌbaɪəʊdaɪˈvɜːsɪti/
• Definition: The variety and variability of all forms of life — including genetic diversity within species, species diversity within ecosystems, and ecosystem diversity across landscapes — within a given region or across the entire planet.
• Origin: A modern compound coined in 1985 in the United States, formed from Greek bios ("life") and Latin diversitas ("variety, difference"); the term was popularised by the 1986 National Forum on BioDiversity organised by E.O. Wilson.

Endemic

• Pronunciation: /ɛnˈdɛmɪk/
• Definition: A species that is native to and found exclusively within a particular, defined geographic area — such as an island, a mountain range, or a country — with no naturally occurring populations elsewhere in the world.
• Origin: From Neo-Latin endēmicus, derived from Greek endēmos ("native"), combining en ("in") and dēmos ("the people"); originally a medical term for diseases constantly present in a locality, later adopted in ecology to describe geographically restricted species.

Keystone Species

• Pronunciation: /ˈkiːstəʊn ˈspiːʃiːz/
• Definition: A species that has a disproportionately large effect on its ecosystem relative to its abundance, such that its removal would cause significant structural change to the ecological community.
• Origin: Coined by American zoologist Robert T. Paine in 1969 after his experiments on the starfish Pisaster ochraceus in Pacific Northwest tidal pools; the term draws an analogy with the architectural keystone — the central wedge-shaped stone at the top of an arch that holds the entire structure together.

Key Terms

Biodiversity Hotspot

• Pronunciation: /ˌbaɪəʊdaɪˈvɜːsɪti ˈhɒtspɒt/
• Definition: A biogeographic region that simultaneously meets two strict criteria — it must contain at least 1,500 species of vascular plants as endemics (more than 0.5% of the world's total) AND it must have lost at least 70% of its primary native vegetation — qualifying it as both biologically rich and critically threatened. Conservation International currently recognises 36 global biodiversity hotspots, which collectively cover only 2.5% of Earth's land surface yet support more than half of the world's plant species as endemics and nearly 43% of endemic bird, mammal, reptile, and amphibian species.
• Context: The concept was first proposed by British ecologist Norman Myers in a 1988 paper in The Environmentalist, where he identified 10 tropical forest "hotspots" based on high endemism and serious habitat loss, without formal quantitative criteria. Conservation International adopted the concept as its institutional blueprint in 1989. In a landmark 2000 paper in Nature by Myers and colleagues, quantitative thresholds were introduced, expanding the list to 25 hotspots; subsequent revisions brought the total to 36. India hosts four hotspots: Western Ghats (~7,402 plant species with 24 endemic genera; UNESCO World Heritage Site), Himalayas (~10,000 plant species, ~3,160 endemic), Indo-Burma (extends into SE Asia; over 13,500 plant species), and Sundaland (India's Nicobar Islands form the northernmost extent).
• UPSC Relevance: GS3 Environment and Biodiversity. Prelims tests both criteria simultaneously (1,500 endemic plants AND 70% habitat loss — not just high biodiversity alone, which is a common trap), the total number of global hotspots (36), and India's four hotspots (Western Ghats, Himalayas, Indo-Burma, Sundaland). Mains asks about conservation strategies for hotspots and the tension between development and biodiversity preservation — especially in the Western Ghats (Gadgil Committee and Kasturirangan Committee recommendations on Ecologically Sensitive Areas). For high-scoring answers, emphasise that hotspots are prioritisation tools: they direct limited conservation resources to areas where investment will protect the most species per dollar spent.

IUCN Red List

• Pronunciation: /ˌaɪjuːsiːˈɛn rɛd lɪst/
• Definition: The world's most comprehensive inventory of the global conservation status of biological species, maintained by the International Union for Conservation of Nature (headquartered in Gland, Switzerland), classifying species into nine categories — Extinct (EX), Extinct in the Wild (EW), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD), and Not Evaluated (NE) — based on quantitative criteria assessing extinction risk. As of the October 2025 update, the Red List includes 172,620 assessed species, of which 48,646 are threatened with extinction (in the CR, EN, or VU categories).
• Context: Established in 1964 by the IUCN, with the first two Red List volumes published in 1966 by conservationist Noel Simon (covering mammals and birds). The word "red" was chosen because it universally signals danger. The Red List is updated multiple times per year with new assessments and reassessments. The April 2025 update included 169,420 species (47,187 threatened), and the October 2025 update expanded to 172,620 species. Recent additions include nearly 100 threatened European bee species and findings that more than half of bird species globally are in decline. For India, key species assessments include: Bengal Tiger — EN (~3,682 in India, 2022 census), Snow Leopard — VU (718 in India, SPAI 2019–23), Great Indian Bustard — CR (~150 wild individuals), Gangetic Dolphin — EN (~6,324, WII 2021–23 survey), and Asiatic Lion — EN (891 in Gir, 2025 census).
• UPSC Relevance: GS3 Environment. Prelims regularly tests IUCN categories (EX, EW, CR, EN, VU, NT, LC — remember the descending order of threat) and the classification of specific Indian species (Great Indian Bustard — CR, Gangetic Dolphin — EN, Asiatic Lion — EN, Snow Leopard — VU). Typically 2-3 Prelims questions annually on species-in-news and their IUCN status. Mains connects Red List data to conservation policy, Wildlife Protection Act schedules (Schedule I for highest protection), India's National Wildlife Action Plan, and the effectiveness of flagship species programmes like Project Tiger. Remember that "threatened" encompasses CR + EN + VU combined.
