Forest And Wildlife Resources Class 10 Chapter Notes

Key Points: Must Remember

• India is one of the world's richest countries in terms of its vast array of biological diversity.
• Species are categorized by IUCN into Normal, Vulnerable, Endangered, Rare, Endemic, and Extinct species based on their risk of extinction.
• Major causes of forest and wildlife depletion include expansion of agriculture, mining, large-scale development projects, grazing, and collection of fuelwood.
• Habitat destruction, hunting, poaching, environmental pollution, and forest fires are also significant threats.
• Conservation is crucial for preserving ecological diversity, our life support systems (water, air, soil), and genetic diversity of plants and animals.
• Government initiatives like the Indian Wildlife (Protection) Act of 1972 aim to protect habitats and ban hunting.
• Project Tiger (1973) is a major wildlife conservation project aimed at protecting tigers, an endangered species, and their habitats.
• Forests are classified into Reserved, Protected, and Unclassed Forests based on the degree of protection.
• Community participation, such as the Bishnoi movement and Chipko movement, plays a vital role in forest and wildlife conservation.
• Joint Forest Management (JFM) involves local communities in the management and restoration of degraded forests.

Essential Definitions for Exams

Biodiversity (Biological Diversity)

The variety of living organisms existing on Earth, their genetic differences, and the ecosystems they form.

Endangered Species

Species in danger of extinction whose survival is difficult if the negative factors causing their decline continue to operate.

Vulnerable Species

Species whose population has declined to levels from where it is likely to move into the endangered category in the near future if the negative factors continue.

Endemic Species

Species that are found only in some particular areas, usually isolated by natural or geographical barriers.

Extinct Species

Species that are no longer found after searches of known or likely areas where they may occur. (e.g., Asiatic Cheetah).

Reserved Forests

More than half of the total forest land in India has been declared Reserved Forests. These are considered the most valuable for forest and wildlife conservation.

Protected Forests

Almost one-third of the total forest area is Protected Forest. These are protected from any further depletion.

Unclassed Forests

These are other forests and wastelands belonging to both government and private individuals/communities.

Joint Forest Management (JFM)

A program initiated in 1988 involving local communities in the management and restoration of degraded forest land. In return, communities get benefits like timber and non-timber forest produce.

The Peril of Biodiversity: Causes of Depletion

India is exceptionally rich in biological diversity, home to an estimated 8% of the world's total species. This vast array of flora and fauna forms complex ecosystems that provide essential services, from regulating climate to purifying water and soil. However, this invaluable natural heritage is under severe threat, primarily due to human activities. The rapid expansion of agriculture post-independence, driven by growing population and demand, led to the conversion of vast forest areas into farmland. Large-scale development projects, such as river valley projects and hydroelectric dams, have submerged thousands of square kilometers of forests. For instance, the Narmada Sagar Project alone is estimated to have submerged 40,000 hectares of forest.

Mining activities, particularly for minerals like Bauxite or Manganese, are another significant cause of deforestation and habitat destruction. The Dooars region of West Bengal, for example, has suffered severe degradation due to mining. Grazing and fuelwood collection, while often sustainable at smaller scales, become major pressures when unregulated and extensive, particularly in marginal forest areas. Other indirect factors contributing to the depletion include hunting and poaching for commercial purposes, environmental pollution (acid rain, toxic waste), forest fires, and over-exploitation of resources. The combination of these pressures leads to habitat destruction, fragmenting ecosystems and isolating populations, making species more vulnerable to extinction. Understanding these intertwined causes is crucial for devising effective conservation strategies to protect India's unique biodiversity.

Forest Classification for Conservation

Exam Tip: Mastering Conservation Topics

For questions on conservation, remember to provide a balanced answer that includes both government initiatives and community efforts. When asked about the causes of depletion, categorize them into agricultural expansion, developmental projects, mining, and specific human activities like hunting or pollution. Use specific examples like Project Tiger for government action or the Chipko Movement for community participation. Also, be precise with definitions of species categories (Endangered, Vulnerable, Endemic, Extinct) and differentiate clearly between Reserved and Protected Forests as these are common distinction questions. Don't just list points; briefly explain how each factor contributes to depletion or conservation.

Quick Revision Check

• Q: What is meant by 'Endemic Species'? Give an example. A: Endemic species are those found only in particular geographical areas, often isolated by natural barriers. An example is the Nicobar Pigeon or the Andaman wild pig.
• Q: List two major causes of forest and wildlife depletion in India. A: Two major causes are: (1) Expansion of agriculture, converting forest land into farms. (2) Large-scale development projects like river valley projects and mining activities.
• Q: What was the primary objective of 'Project Tiger'? A: The primary objective of Project Tiger, launched in 1973, was to protect endangered tiger populations in India and preserve their habitats to maintain ecological balance.
• Q: How do local communities contribute to forest conservation? A: Local communities contribute through direct protection (e.g., Bishnoi village), resisting deforestation (e.g., Chipko movement), and participating in programs like Joint Forest Management (JFM) to restore degraded forests.
