Chapter 2: Forest and Wildlife Resources
This chapter delves into India's rich biodiversity, the critical importance of forests and wildlife, and the urgent conservation challenges facing these precious resources. We explore everything from classification of species based on conservation status to the complex causes of biodiversity depletion, examining both traditional conservation wisdom and modern conservation strategies that are shaping India's environmental future.
1. Understanding Biodiversity: India's Living Wealth
Biodiversity refers to the variety of life forms found in a particular region, encompassing genetic diversity within species, diversity between species, and diversity of ecosystems. India is one of the world's 12 mega-diversity countries, hosting approximately 8% of the world's recorded species despite having only 2.4% of the world's land area.
- India's Biological Richness: With 47,000 plant species (15th globally) and 91,000 animal species (8th globally), India's biodiversity is both vast and unique. The Western Ghats and Eastern Himalayas are among the world's 34 biodiversity hotspots—regions with exceptional concentrations of endemic species that are under severe threat.
- Forest-Wildlife Interdependence: Forests are not just tree collections but complex ecosystems where flora and fauna exist in intricate relationships. Wildlife depends on forests for habitat, food, and breeding grounds, while forests depend on wildlife for pollination, seed dispersal, and nutrient cycling.
- The Keystone Species Concept: Certain species like tigers, elephants, and vultures play disproportionately large roles in maintaining ecosystem structure. Their loss triggers cascading effects throughout the ecosystem, making their conservation particularly critical.
Critical Insight: India's biodiversity isn't evenly distributed—about 33% of plant species and 62% of amphibian species are endemic to specific regions like the Western Ghats or Northeast. This concentration makes localized extinction threats particularly dangerous for global biodiversity.
2. Historical Relationship Between Indians and Forests
The Indian subcontinent's relationship with forests spans millennia, evolving through distinct phases that reflect changing social, economic, and political contexts:
- Ancient and Medieval Periods: Forests were integral to Indian civilization, featuring prominently in scriptures, art, and daily life. Sacred groves (devrais, kavus) protected biodiversity through religious taboos. Communities practiced shifting cultivation with long fallow periods allowing forest regeneration.
- Colonial Era (1757-1947): The British introduced "scientific forestry" that prioritized commercial timber (teak, sal) over biodiversity. The Forest Act of 1865 and 1878 declared forests state property, criminalizing traditional use by local communities and creating the "criminal tribes" category for forest dwellers.
- Post-Independence Development Phase (1947-1970s): Large-scale deforestation for agriculture (Green Revolution), dams, and industries. Forest cover declined from about 40% at independence to 19.5% by the 1970s, though definitions and measurement methods varied.
- Environmental Awakening (1970s-1990s): Chipko Movement (1973) and growing ecological awareness. Wildlife Protection Act (1972) and Forest Conservation Act (1980) established legal frameworks for protection.
3. Conservation Timeline: Milestones in Indian Wildlife Protection
- Initiated with 9 tiger reserves covering 9,115 sq km

- Biosphere Reserves concept introduced (Nilgiri first in 1986)
- Elephant corridors identified and protected
- Community-based conservation initiatives began emerging
- Forest Rights Act (2006) recognized tribal and forest dwellers' rights
- National Wildlife Action Plan (2002-2016) adopted landscape approach
- Compensatory Afforestation Fund Act (2016) created funding mechanism
4. Classification Based on Conservation Status
IUCN Red List Categories with Indian Examples

5. Causes of Depletion and Conservation Strategies
A. Major Causes of Forest and Wildlife Depletion in India
- Habitat Destruction and Fragmentation: Large-scale clearing for agriculture, dams, mining, and urbanization. India lost 1.6 million hectares of forest between 2015-2020. Fragmentation creates "islands" of habitat too small to sustain viable populations.
- Poaching and Illegal Wildlife Trade: Tigers for skins/bones, elephants for ivory, rhinos for horns, pangolins for scales. Estimated $20 billion annual illegal wildlife trade in India. Sophisticated networks operate across borders.
- Human-Wildlife Conflict: As habitats shrink, animals venture into human areas. Elephants raid crops (annual loss ~₹2,000 crore), tigers attack livestock, leopards enter settlements. Retaliatory killings common.
- Invasive Alien Species: Lantana, Parthenium, Water hyacinth outcompete native species. Lantana covers 40% of Indian tiger reserves, altering herbivore food availability.
- Climate Change Impacts: Shifting vegetation zones in Himalayas, coral bleaching in marine ecosystems, altered migration patterns. Western Ghats endemic species particularly vulnerable.
B. Innovative Conservation Approaches
- Joint Forest Management (JFM): Partnerships between Forest Departments and local communities. Over 118,000 JFM committees managing 25 million hectares. Communities get 25-50% share of non-timber forest produce.
- Eco-development Around Protected Areas: Reducing dependency on forests by providing alternative livelihoods: beekeeping, ecotourism, handicrafts. Periyar Tiger Reserve's eco-development committees successful model.
- Wildlife Corridor Protection: Identifying and securing movement corridors between protected areas. Elephant corridors reduced from 88 to 28 functional ones; securing remaining critical.
- Species Recovery Programs: Focused efforts for critically endangered species: Great Indian Bustard (breeding in captivity), Vulture (diclofenac ban), Gharial (river cleaning, nesting sites).
Forest Rights Act 2006 Revolution: This landmark legislation recognized forest dwellers' rights after centuries of marginalization. It acknowledges: Individual Forest Rights (to cultivated land), Community Forest Rights (to manage and protect forests), and Habitat Rights for Particularly Vulnerable Tribal Groups. While controversial among conservationists fearing forest degradation, proponents argue secure rights create conservation incentives.

8. Conservation Champions and Community Initiatives
Pioneers of Indian Wildlife Conservation:
- Jim Corbett (1875-1955): Hunter-turned-conservationist, instrumental in establishing Hailey National Park (now Jim Corbett National Park). His books raised early awareness about tiger conservation.
- Salim Ali (1896-1987): "Birdman of India," documented Indian avifauna systematically. His advocacy saved Silent Valley from hydroelectric project. Bharatpur Bird Sanctuary owes much to his efforts.
- Sunderlal Bahuguna (1927-2021): Chipko Movement leader who coined "Ecology is permanent economy." Advocated Himalayan ecosystem protection through Gandhian methods.
- K. Ullas Karanth (contemporary): Scientific tiger conservation using camera traps and rigorous monitoring. Founded Centre for Wildlife Studies, revolutionized tiger estimation methods.
Successful Community Conservation Models:
- Bishnoi Community (Rajasthan): Follow 29 principles including protection of all life. 1730 Khejarli massacre where 363 Bishnois died protecting trees. Their villages have higher biodiversity than surrounding areas.
- Mishing Tribe (Assam): Traditional community fishing methods that allow fish regeneration. Their "borang" fishing technique sustainable unlike commercial trawling.
- Soliga Tribe (Karnataka): Successfully claimed Community Forest Rights in Biligiri Rangana Hills. Now co-manage forests with Forest Department, combining traditional knowledge with modern conservation.
9. Essential Terminology for Exams
Endemic Species: Species found only in a specific geographical area and nowhere else naturally. India has high endemism: 33% plants, 62% amphibians endemic. Examples: Lion-tailed macaque (Western Ghats), Sangai deer (Manipur), Nilgiri tahr (Nilgiris).
Biodiversity Hotspot: A biogeographic region with significant levels of biodiversity that is threatened by human activities. To qualify: must have at least 1,500 endemic plant species and have lost at least 70% of original habitat. India hosts 4 hotspots: Himalayas, Indo-Burma, Sundaland, Western Ghats-Sri Lanka.
In-situ Conservation: Conservation of species in their natural habitats. Includes protected areas (national parks, sanctuaries), biosphere reserves, sacred groves. Maintains ecological processes and evolutionary potential. Example: Tiger conservation in natural forest habitats.
Ex-situ Conservation: Conservation of species outside their natural habitats. Includes zoos, botanical gardens, seed banks, cryopreservation, captive breeding. Acts as insurance against extinction. Example: Vulture breeding centers in Pinjore, Bhopal, Rani.
Habitat Fragmentation: Process where large continuous habitats are divided into smaller, isolated patches due to human activities (roads, agriculture, settlements). Creates "island" populations vulnerable to genetic problems, climate change, and local extinction. Measured by edge effects and patch connectivity.
Chapter-Specific Revision Checklist
Chapter-Specific Exam Strategy: For questions on conservation, always mention both biological importance and socio-economic context. Use the "4C Framework": Causes (of problem), Consequences (ecological & social), Conservation (strategies), Community (role and rights). For 5-mark questions on depletion causes, structure as: 1) Habitat destruction, 2) Poaching/trade, 3) Human-wildlife conflict, 4) Invasive species, 5) Climate change - with examples for each.
Data Points Mastery: Forest cover (21.71% of geographical area), Protected Areas (998, 1.73 lakh sq km, 5.28%), Tiger population (3,682), Elephant population (~29,964), Vulture decline (99.9% for some species), JFM committees (118,213), Annual deforestation (1.6 million hectares 2015-20). These precise numbers demonstrate thorough preparation.
Note: This chapter bridges ecological science with social realities. Success in exams requires understanding both the biological aspects (species, ecosystems, conservation biology) and the human dimensions (community rights, conflicts, traditional knowledge). Always connect conservation challenges to broader development questions. For deeper insights, study specific case studies: Project Tiger's successes and failures, the vulture-diclofenac story, Niyamgiri mining conflict, and successful JFM models like Arabari in West Bengal.
