2. Answer the following questions in about 30 words.

(i) What is natural vegetation? Under what climatic conditions are tropical evergreen forests develop?

Answer: Natural vegetation refers to plant life that grows naturally in a region without significant human interference and adapts to the local climate and soil conditions over time.

Tropical evergreen forests develop in hot, humid areas that receive more than 200 cm of annual rainfall and have average temperatures above 22°C. In India, these forests are mainly found in the Western Ghats, the North-Eastern states, and the Andaman and Nicobar Islands.

(ii) What do you understand by social forestry?

Answer: Social forestry is the practice of managing, protecting, and planting trees on community lands and barren areas to meet environmental, social, and rural development needs. It helps improve ecological balance and provides resources such as fuelwood and fodder. Social forestry is broadly classified into urban forestry, rural forestry, and farm forestry.

(iii) Define Biosphere reserves?

Answer: Biosphere Reserves are large protected areas that conserve unique ecosystems, biodiversity, and natural habitats. Recognised under UNESCO’s Man and Biosphere (MAB) Programme, they promote conservation, sustainable development, and scientific research while maintaining a balance between humans and the environment.

(iv) What is the difference between forest area and forest cover?

Answer: Forest area refers to land officially recorded as forest by government authorities, regardless of whether trees are present. Forest cover, on the other hand, represents the actual area covered by forests and tree canopies. Forest area is determined through official land records, whereas forest cover is assessed using satellite imagery and aerial surveys.

3. Answer the following questions in not more than 150 words.

(i) What steps have been taken up to conserve forests?

Answer: Several measures have been introduced to conserve forests and maintain ecological balance. One of the most important initiatives is social forestry, which focuses on afforestation and forest protection to support environmental and rural development. It includes:

• Urban Forestry: Planting and managing trees in urban areas such as parks, roadsides, green belts, and industrial zones.

• Rural Forestry: Encouraging tree plantation in rural regions through agro-forestry and community-based forestry programmes.

• Farm Forestry: Promoting the cultivation of trees alongside crops to produce timber, fuelwood, fodder, and fruits.

Another important measure is community forestry, where trees are planted and managed on community lands such as village commons, canal banks, roadsides, and school premises. 

In addition, farm forestry encourages farmers to grow trees on their private lands, with support from state forest departments through the distribution of free seedlings. These initiatives help increase forest cover and ensure the sustainable use of forest resources.

(ii) How can people’s participation be effective in conserving forests and wildlife?

Answer:

• People’s participation plays a crucial role in the conservation of forests and wildlife.

• Since human activities such as deforestation, illegal hunting, and poaching are major threats to biodiversity, public awareness and cooperation are essential for protecting natural resources.

• To safeguard wildlife, the Government of India enacted the Wildlife Protection Act, 1972, which prohibits hunting and provides legal protection to endangered species.

• The Act also supports the establishment and management of protected areas such as national parks and wildlife sanctuaries.

• It was further strengthened by amendments that imposed stricter penalties and improved conservation efforts.

• While government policies provide the framework for protection, their success depends largely on active public involvement.

• By participating in conservation programmes, protecting natural habitats, and promoting sustainable practices, people can significantly help preserve forests and wildlife for future generations.
