Chapter 1
INTRODUCTION
India is universally celebrated as one of the world's 17 "Megadiverse Nations". Occupying just 2.4% of the Earth's total land area, India harbors an extraordinary 7% to 8% of all recorded global species of flora and fauna. This exceptional biodiversity is driven by India's vast geographic diversity—spanning snow-capped Himalayan peaks and arid Rajasthan deserts to lush Western Ghats rainforests, mangrove estuaries, and tropical coral island archipelagos.
Biodiversity provides essential ecosystem services that sustain human life—including climate regulation, watershed protection, agricultural crop pollination, soil fertility maintenance, and medicinal resources. However, habitat fragmentation, deforestation, illegal wildlife poaching, invasive alien species, and climate change pose severe threats to India's natural heritage.
To protect these priceless ecological assets, India has designated Four Global Biodiversity Hotspots (Western Ghats, Eastern Himalayas, Indo-Burma, and Sundaland) and established an extensive network of Protected Areas (PAs) comprising over 100 National Parks, 560+ Wildlife Sanctuaries, 55+ Tiger Reserves, and 18 Biosphere Reserves (12 recognized under the UNESCO MAB Program).
Furthermore, India has spearheaded landmark species-specific recovery initiatives—such as Project Tiger (1973), Project Elephant (1992), Project Snow Leopard (2009), Project Dolphin (2020), and the Vulture Conservation Breeding Programme to rescue critically endangered species from the brink of extinction.
For aspirants preparing for competitive examinations such as UPSC Civil Services (GS Paper III Environment & Ecology), State Public Service Commissions (BPSC, UPPSC, MPPSC, RAS), SSC CGL, and Forestry services, a thorough mastery of biogeographic zones, 4 hotspot criteria, IUCN Red List categories (CR, EN, VU), and species conservation projects is essential.
This comprehensive master career guide provides an exhaustive breakdown of Biodiversity of India. We cover every ecological detail—from 10 biogeographic zones and 4 hotspot profiles to IUCN critically endangered species, Project Tiger NTCA rules, 12 exam-focused FAQs, and essential revision tools.

- Core-Buffer Model:
- Critical Tiger Habitat (CTH/Core): Inviolate zone where no human activity is permitted; 800+ villages have been voluntarily relocated from Tiger Reserve cores.
- Buffer/Fringe Area: Peripheral area where local community activities are managed through co-existence programs.
- Tiger Census Results:
| Year | Tiger Count | Method |
|---|---|---|
| 1973 | 1,827 | Manual pugmark method |
| 2006 | 1,411 | Camera trap + GIS (wake-up call) |
| 2010 | 1,706 | Camera trap (Project Monitoring System) |
| 2014 | 2,226 | Camera trap + occupancy modeling |
| 2018 | 2,967 | Camera trap (phase IV census) |

Chapter 31
# PROJECT CHEETAH 2022 — WORLD'S FIRST INTERCONTINENTAL CARNIVORE TRANSLOCATION
- Background: The Asiatic Cheetah (Acinonyx jubatus venaticus) was declared extinct in India in 1952 — the last three cheetahs were shot by Maharaja Ramanuj Pratap Singh Deo of Surguja in what is now Chhattisgarh.
- Scientific Decision: Since Asiatic Cheetahs survive only in Iran (fewer than 40 individuals), with no prospect of sourcing them for reintroduction, the Wildlife Institute of India (WII) decided to use the closely related African Cheetah (Acinonyx jubatus jubatus).
- Phase 1 — Namibia (September 2022): PM Narendra Modi personally received 8 cheetahs (5 female, 3 male) from Namibia at Kuno National Park.
- Phase 2 — South Africa (February 2023): 12 more African cheetahs (7 male, 5 female) translocated from South Africa.
- Kuno National Park: Located in Sheopur district, Madhya Pradesh; chosen after a comprehensive habitat suitability assessment by the Supreme Court-appointed Committee and WII experts.
- Objective: Establish a self-sustaining population of 40-50 cheetahs over 15 years; restore open grassland and dry deciduous forest ecosystems; revive predator-prey balance.
---
The Great Indian Bustard (Ardeotis nigriceps) is at the absolute brink of extinction — with fewer than 150 individuals surviving in the wild (2023 estimate):
- IUCN Status: Critically Endangered (CR)
- State Bird of: Rajasthan
- Last strongholds: Desert National Park (DNP), Jaisalmer district, Rajasthan; Naliya grasslands, Gujarat
- Primary Threat: Collision with overhead power transmission lines during flight. As a heavy bird (up to 15 kg — heaviest flying bird in India), GIB cannot rapidly change flight direction to avoid cables.
- Supreme Court Intervention: In a landmark 2021 judgment (M.K. Ranjitsinh v. Union of India), the SC ordered that overhead power lines in GIB habitat in Rajasthan and Gujarat be converted to underground cables — but later modified this order in 2024 acknowledging technical feasibility constraints, allowing diverters instead.
- Vikram Solar Park Controversy: Large solar parks being built in Jaisalmer (Pokaran, Fatehgarh) overlap with GIB core habitat areas — creating a tension between renewable energy expansion (Panchamrit targets) and GIB conservation.
- Conservation Actions: An "Emergency Response" breeding program has been set up at Sam, Jaisalmer with eggs harvested from wild nests for captive incubation at Jaisalmer Breeding Centre.

- Habitat: Gangetic-Brahmaputra-Meghna and Karnaphuli-Sangu river systems in India, Bangladesh, Nepal.
- Special Feature: Functionally blind — navigates entirely through echolocation (biosonar) by emitting ultrasonic clicks. Locally called "Susu" for the sound it makes breathing.
- First Dolphin Sanctuary: Vikramshila Gangetic Dolphin Sanctuary, Bhagalpur district, Bihar (60.5 km stretch of Ganga between Sultanganj and Kahalgaon).
- Population: Estimated at approximately 3,000-4,000 individuals across Indian rivers; classified as Endangered (EN) on IUCN Red List.
- Threats: Accidental entanglement in fishing nets, sand mining disturbing riverbed habitat, water extraction reducing river flows, and oil spills.
