Forest and Wildlife Resources – Long Answer Questions (CBSE Class 10)

Medium Level (Application & Explanation)

Q1. Explain the three levels of biodiversity and show why each level matters for India with examples.

Answer:

Biodiversity has three levels: Genetic, Species, and Ecosystem diversity.
Genetic diversity is variation within a species. It helps species adapt to diseases and climate change. Example: different rice varieties like Basmati, Sona Masuri, and IR-8; different mango types like Alphonso, Dasheri, Langra.
Species diversity is the variety of species in an area. It keeps food webs stable and supports ecosystem services like pollination. Example: Western Ghats with many frogs, birds, and orchids; Sundarbans with tigers, crocodiles, and mangroves.
Ecosystem diversity means different habitats like forests, deserts, wetlands, and alpine meadows. It supports different life forms. Example: Thar Desert, Himalayan meadows, Chilika Lake wetlands.
Each level is important for food security, medicine, livelihoods, and climate regulation. Losing any level weakens nature’s ability to recover and support people.

Q2. Identify major threats to biodiversity in India and explain how protected areas and community participation reduce these threats.

Answer:

Major threats include deforestation, habitat fragmentation, poaching and illegal wildlife trade, pollution, climate change, and invasive species that displace native species.
Protected areas like national parks, wildlife sanctuaries, and biosphere reserves protect large habitats and keep breeding grounds safe. Examples: Corbett, Kaziranga, Gir, Nilgiri Biosphere Reserve.
Stronger laws like the Wildlife Protection Act, 1972 ban hunting and regulate trade in wildlife products.
Community participation makes protection practical. The Bishnoi protect trees and blackbucks; the Chipko Movement stopped large-scale tree felling; Joint Forest Management (JFM) shares benefits and responsibilities with local people (success in Arabari, West Bengal).
Together, these actions reduce habitat loss, stop poaching, and build local stewardship. People gain livelihoods and incentives to conserve, making protection sustainable.

Q3. Classify species based on conservation status and explain why this classification guides better policy and action.

Answer:

Species can be grouped as Normal, Vulnerable, Endangered, Rare, and Extinct (in India).
Normal species have stable populations (e.g., cattle, rats) and need monitoring to stay stable.
Vulnerable species are declining and may become endangered (e.g., Gangetic dolphin, Snow leopard).
Endangered species face a very high risk of extinction (e.g., Bengal tiger, Indian elephant, Asiatic lion).
Rare species exist in small numbers (e.g., Himalayan brown bear).
Extinct in India means no longer found in the wild within India (e.g., Cheetah historically; reintroduction efforts are ongoing).
This classification helps governments and scientists prioritise funding, create species recovery plans, protect critical habitats, and build corridors. It also guides education, law enforcement, and research to where they are needed most.

Q4. Describe India’s main strategies for conserving forests and wildlife, and explain the “5 Ps of conservation.”

Answer:

India uses a mix of law, projects, protected areas, planting, and people participation—the 5 Ps.
1. Laws: The Wildlife Protection Act, 1972 created national parks, sanctuaries, and biosphere reserves and controls hunting and trade.
1. Projects: Project Tiger (1973) and Project Elephant (1992) protect animals and their habitats and corridors; crocodile breeding revived populations.
1. Protected areas: 18 biosphere reserves (e.g., Nilgiri, Sundarbans, Pachmarhi) plus many parks and sanctuaries protect ecosystems and species.
1. Planting: Social forestry, agroforestry, and afforestation increase green cover and reduce pressure on natural forests.
1. People: JFM, Bishnoi community actions, and Chipko show how local stewardship works.
These strategies maintain ecological balance, support livelihoods, and improve soil, water, and climate services.

Q5. What is Project Tiger? Explain its goals, methods, successes, and challenges with examples.

Answer:

Project Tiger (1973) aims to protect the Bengal tiger and its habitat, reduce human-tiger conflict, and restore ecosystem health.
Methods include creating tiger reserves (now about 54), using anti-poaching units like the Special Tiger Protection Force (STPF), improving patrolling and surveillance (e.g., camera traps, M-STrIPES), protecting corridors, and relocating villages from core areas to reduce disturbance.
Successes: Tiger numbers rose from 1,411 (2006) to over 3,000 (2022); reintroductions in Sariska and Panna after local extinction; corridor protection like Kanha–Pench and Corbett–Rajaji keeps genetic diversity healthy.
Challenges: Poaching, habitat loss due to roads/mining, and conflict near forests.
Overall, protecting tigers conserves entire forests, securing water, climate, and biodiversity for people.

High Complexity (Analytical & Scenario-Based)

Q6. “Saving top predators like the tiger protects the entire ecosystem.” Analyse this statement with ecological and human benefits.

Answer:

Tigers are apex predators and often keystone species. They control herbivore populations (like deer), preventing overgrazing and protecting forest regeneration.
Healthy forests support pollinators, seed dispersal, and soil fertility, which indirectly benefits agriculture near forests.
Tiger habitats include watersheds. Protecting them safeguards rivers and streams that supply drinking water, irrigation, and hydropower.
Reserves act as carbon sinks, helping climate regulation by storing carbon and reducing heat.
Protection builds eco-tourism opportunities (e.g., Ranthambore, Kaziranga), creating jobs and funding for conservation.
By securing corridors, tigers maintain genetic diversity across populations.
Thus, saving tigers is not just about one species; it preserves entire food webs, ecosystem services, and livelihoods, making conservation economically and ecologically sensible.

Q7. Village relocation from core tiger areas is controversial. Evaluate its ecological benefits, social costs, and fair solutions.

Answer:

Ecological benefits: Removing settlements from core zones reduces disturbance, allows prey to recover, lowers firewood extraction, and improves breeding success of tigers. It also reduces conflict and livestock depredation.
Social costs: Communities lose homes, customary rights, and cultural ties to forests. If relocation is poor, people face landlessness, unemployment, and inadequate services.
Fair solutions: Ensure free, prior, and informed consent; provide adequate compensation, quality land-for-land, housing, schools, healthcare, and livelihood training. Include community choice of relocation sites.
Use co-management in buffer zones through JFM, reduce conflict via early-warning systems, solar fencing, and corridor protection.
Transparency, grievance redressal, and long-term support turn relocation from a burden into a win–win for people and wildlife.

Q8. A highway must pass through a notified wildlife corridor. Design a balanced plan that ensures connectivity and safety.

Answer:

First, confirm the corridor alignment using camera traps, GPS data, and local knowledge. If feasible, re-align the route to avoid the core corridor.
If re-routing is impossible, build wildlife underpasses/overpasses, with correct width, height, and natural vegetation to guide use. Install fencing to channel animals to crossings.
Enforce speed limits, night-time restrictions, rumble strips, and warning signage. Place sensor-based alerts and CCTV for monitoring.
Offset habitat loss with compensatory afforestation and restoration of nearby degraded patches to keep landscape connectivity.
Set up a joint monitoring committee (forest, road agency, researchers, local communities). Track wildlife crossings, roadkills, and traffic; adapt measures as needed.
Fund long-term maintenance through a mitigation budget built into the project cost. This plan balances development with biodiversity safety.

Q9. A lake is overrun by water hyacinth and fish are dying. Propose an integrated restoration plan and explain the science behind it.

Answer:

Problem: Water hyacinth (invasive) spreads fast, blocks sunlight, reduces oxygen, and causes eutrophication. Fish die due to low dissolved oxygen and toxic algal blooms fuelled by nutrients from sewage and runoff.
Immediate actions: Mechanical removal with booms and skimmers; community clean-up drives; limited biological control where safe.
Reduce nutrient inflow: Upgrade wastewater treatment, stop untreated sewage, create constructed wetlands to filter nutrients, and regulate fertiliser use in the catchment.
Ecological restoration: Replant native aquatic plants, create littoral zones, and install aerators temporarily. Restock fish with **native speci...
