Classification of Forests in India

The government classifies forest lands into three main categories to manage and conserve them effectively:

Reserved Forests

• Proportion: More than half ($>50\%$) of the total forest land in India has been declared as reserved forests.

• Significance: These are regarded as the most valuable forests when it comes to the conservation of forest and wildlife resources.

• Control: Activities like hunting and grazing are strictly restricted here.

Protected Forests

• Proportion: Almost one-third ($\approx 33\%$) of the total forest area falls under this category, as declared by the Forest Department.

• Significance: This land is strictly protected from any further depletion or environmental degradation.

Unclassed Forests

• Definition: These consist of other forests and wastelands.

• Ownership: They belong to both the government and private individuals or local communities.

Categories of Existence (Threat Levels)

Based on the International Union for Conservation of Nature (IUCN), plants and animals are classified into distinct categories depending on their population status:

Biodiversity and Species Estimates

• Global Standing: India is recognized as one of the world’s richest countries regarding its vast array of biological diversity.

• Undiscovered Species: The number of species yet to be discovered in India is estimated to be possibly twice or thrice the number already known.

• Flora at Risk: Some estimates suggest that at least 10 per cent of India’s recorded wild flora is on the threatened list.

• Mammals at Risk: At least 20 per cent of India's mammals are featured on the threatened list.

• India has 104 national parks and over 500 wildlife sanctuaries.

• The Gir Forest (Gujarat) is the only natural habitat of the Asiatic lion.

• The Kaziranga National Park (Assam) is famous for the one-horned rhinoceros.

• The Sundarbans delta is the largest mangrove forest in the world.

• India is home to 2,000 bird species and 2,500 fish species.

Threat to Flora and Fauna

1. Colonial Exploitation and Policies

• The Drivers: This destruction was primarily driven by the expansion of the railways, commercial and scientific forestry, agriculture, and intensive mining activities.

• "Enrichment Plantation" (Commercial Forestry): Environmental activists note that colonial forest policies promoted a few favored species at the cost of native biodiversity. In this practice, a single commercially valuable species was extensively planted, and other diverse native species were systematically eliminated.

• Example 1: Teak monoculture has severely damaged the natural, diverse forests of South India.

• Example 2: Chir Pine (Pinus roxburghii) plantations in the Himalayas directly replaced the native Himalayan Oak (Quercius spp.) and Rhododendron forests.

2. Agricultural Expansion

Even after Independence, agricultural expansion has remained one of the major causes of the depletion of forest resources.

• Encroachment Statistics: Between 1951 and 1980, according to the Forest Survey of India, over 26,200 sq. km of forest area across India was cleared and converted into agricultural land.

• Shifting Cultivation: Substantial parts of the tribal belts, particularly in northeastern and central India, have been heavily deforested or degraded by shifting cultivation (jhum), which is a traditional form of "slash and burn" agriculture.

3. Large-Scale Development and River Valley Projects

Massive infrastructure and development projects have contributed significantly to losing pristine jungle habitats.

• Historical Loss: Since 1951, over 5,000 sq. km of forest has been entirely cleared for various river valley projects.

• Example: The ongoing Narmada Sagar Project in Madhya Pradesh is a prime example; its reservoir and infrastructure are set to inundate 40,000 hectares of vital forest land.

4. Destructive Mining Activities

Mining operations physically strip away topsoil, eliminate flora, and fragment the remaining wildlife habitats.

• Example: The Buxa Tiger Reserve in West Bengal is seriously threatened by ongoing dolomite mining. This operation has severely disturbed the natural habitats of many native species and has directly blocked the crucial migration routes of several animals, including the great Indian elephant.

5. Over-Exploitation for Commercial Demands

When a single species possesses high commercial or medicinal value, it is often gathered to the point of regional ecological collapse.

• Example: The Himalayan Yew (Taxus wallachiana) is a highly valuable medicinal tree found in parts of Himachal Pradesh and Arunachal Pradesh. A chemical compound called "taxol" is extracted from its bark, needles, twigs, and roots to manufacture the biggest-selling anti-cancer drug in the world. Due to intense commercial over-exploitation, thousands of these yew trees have dried up and died across both states over the last decade.

6. Habitat Destruction, Poaching, and Direct Human Interference

The factors—habitat destruction, hunting, poaching, over-exploitation, environmental pollution, poisoning, and devastating forest fires — have systematically caused the decline of India’s wild population.

• Example (The Tiger): The major threats to the tiger population include poaching for illegal trade, a shrinking habitat, a depleting prey base, and a growing human population. The trade of tiger skins and the use of their bones in traditional Asian medicines left the species on the brink of extinction, dropping the subcontinent's population from an estimated 55,000 at the turn of the century down to just 1,827 by 1973. Because India and Nepal host about two-thirds of the world's surviving tigers, they have become the prime targets for illegal trading networks.

7. Inequitable Resource Consumption

Environmental destruction is heavily driven by unequal access, inequitable consumption of resources, and a stark differential sharing of responsibility for environmental well-being.

• The Global Contrast: While third-world overpopulation is often blamed for environmental degradation, an average American actually consumes 40 times more resources than an average Somalian.

• The Domestic Contrast: Similarly, the richest 5 per cent of Indian society causes substantially more ecological damage through their high consumption habits than the poorest 25 per cent, despite the wealthier classes sharing minimum responsibility for maintaining the environment's well-being.

📜 Background of Acts and Movements

1. Wildlife Protection Act, 1972

• Background: Before 1972, India had only scattered laws like the Wild Birds and Animals Protection Act, 1912, which were weak and inconsistent. By the early 1970s, species like tigers and rhinos were near extinction, and India had only five national parks.
• Influence: The Stockholm Conference on Human Environment (1972) pushed India to adopt stronger environmental laws.
• Enactment: Passed on 9 September 1972 by Parliament to provide a uniform framework for wildlife protection across India.
• Features: Six schedules with varying degrees of protection; Schedule I species (like tigers) receive the highest protection.

2. Project Tiger (1973)

• Background: India’s tiger population had collapsed from ~40,000 in the 1900s to just 1,827 by 1972 due to hunting, poaching, and habitat loss.
• Launch: Initiated on 1 April 1973 under Prime Minister Indira Gandhi, following recommendations of the Indian Board of Wildlife.
• Objective: To protect tigers and their habitats by creating tiger reserves with core and buffer zones.
• Legacy: Started with 9 reserves; today India has 50+ reserves and holds nearly 75% of the world’s wild tigers.

3. Chipko Movement (1973–74)

• Background: Originated in Chamoli district, Uttarakhand (then Uttar Pradesh). Villagers depended on forests for fuel, fodder, and water, but government policies favored commercial logging.
• Trigger: The devastating Alaknanda floods of 1970, linked to reckless deforestation, raised ecological awareness.
• Action: Villagers, led by activists like Chandi Prasad Bhatt and Sunderlal Bahuguna, hugged trees to prevent felling.
• Impact: Spread across Himalayan villages; women played a leading role (e.g., Gaura Devi at Reni village in 1974). Led to bans on logging in sensitive areas.

4. Bishnoi Community Conservation

• Background: Founded in 1485 by Guru Jambheshwar (Jambhoji) in Rajasthan after witnessing drought and ecological decline.
• Principles: 29 rules, including bans on cutting green trees and killing animals.
• Historic Event: The Khejarli Massacre (1730), where 363 Bishnois led by Amrita Devi sacrificed their lives to protect khejri trees from being cut.
• Legacy: Bishnois are considered India’s first environmentalists; they protect blackbucks and sacred groves even today.

5. Beej Bachao Andolan (1980s–90s)

• Background: Started in Jardhargaon, Uttarakhand by farmer-activist Vijay Jardhari.
• Trigger: The Green Revolution introduced hybrid seeds that required chemicals and water, eroding traditional seed diversity.
• Action: Movement revived traditional farming practices like Barahnaja (12-crop intercropping system) and conserved indigenous seeds.
• Impact: Saved over 300 rice varieties and promoted sustainable, chemical-free farming.

6. Joint Forest Management (JFM, 1990)

• Background: Colonial forest policies and post-independence state control excluded local communities, leading to degradation.
• Trigger: Success of the Arabari experiment (1972, West Bengal) by forest officer A.K. Banerjee, where villagers were given rights to degraded sal forests in exchange for protection.
• Launch: Formal guidelines issued in 1990 by Government of India.
• Objective: Partnership between Forest Department and local communities; villagers receive usufruct rights (fuelwood, fodder, NTFPs) and share in timber profits.
• Impact: Today covers 20 million hectares with over 100,000 Forest Protection Committees.
