Questions and Solutions

Question 1

Choose the right answer from the four alternatives given below. Sandalwood is an example of:

Evergreen forest
Deciduous forest
Deltaic forest
Thorny forest

Solution: Sandalwood trees are known for shedding their leaves during the dry season to conserve water. This characteristic is typical of deciduous forests, which are found in regions with distinct wet and dry periods. Therefore, sandalwood is an example of vegetation found in deciduous forests.

Question 2

Which one of the following was the purpose of Project Tiger?

to kill tigers
to put tigers in the Zoo
to protect tigers from illegal hunting
to make films on tigers

Solution: Project Tiger was a significant conservation initiative launched in India. Its primary objective was to ensure the survival and protection of the tiger population, which was facing severe threats from poaching and habitat destruction. The project focused on safeguarding tigers from illegal hunting and preserving their natural habitat.

Question 3

In which one of the following states is the Nandadevi Biosphere reserve situated?

Bihar
Uttar Pradesh
Uttarakhand
Odisha

Solution: The Nandadevi Biosphere Reserve is located in the northern Indian state of Uttarakhand. This region is part of the Western Himalayas and is renowned for its high biodiversity, unique flora and fauna, and significant ecological importance.

Question 4

How many of the Biosphere reserves from India are recognised by the UNESCO?

One
Two
Three
Four

Solution: As per the information provided, four Biosphere Reserves in India have been recognized by the UNESCO. These reserves are part of the global network of Biosphere Reserves under the Man and the Biosphere (MAB) Programme, signifying their international importance for conservation and research.

Question 5

Which one of the following proportion of area of the country was targeted to be under forest in Forest Policy of India?

Solution: India's Forest Policy, particularly the National Forest Policy, has set a target to maintain a certain proportion of the country's geographical area under forest cover. The aim is to achieve ecological balance and environmental stability. The policy targets approximately 33 percent of the total geographical area to be under forest cover.

Question 2 (i)

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

Solution: Natural vegetation refers to the plant communities that grow naturally in an area without any significant human interference or cultivation. These plants are adapted to the local environmental conditions. Tropical evergreen forests are a type of natural vegetation that develops under specific climatic conditions. These conditions include warm temperatures throughout the year and heavy rainfall. Specifically, they are found in areas with an annual precipitation of over 200 cm and a mean annual temperature exceeding 22°C, typically located near the equator.

Question 2 (ii)

What do you understand by social forestry?

Solution: Social forestry refers to the practice of managing and protecting forest resources and undertaking afforestation on non-forest lands with the primary goal of benefiting the community. It integrates environmental conservation with social and rural development. Social forestry typically encompasses three main components: urban forestry (planting trees in urban areas), rural forestry (planting trees in villages and on common lands), and farm forestry (planting trees on farm boundaries and private lands).

Question 2 (iii)

Define Biosphere reserves?

Solution: Biosphere reserves are designated areas that protect a significant portion of the planet's biodiversity. These reserves encompass terrestrial, marine, and coastal ecosystems. They are internationally recognized under the framework of UNESCO's Man and the Biosphere (MAB) Programme. Biosphere reserves serve as sites for research, conservation, and sustainable development, promoting a balanced relationship between humans and nature.

Question 2 (iv)

What is the difference between forest area and forest cover?

Solution: The term 'forest area' refers to the land that has been legally notified and recorded as forest land by the government, irrespective of whether it currently supports tree growth or not. In contrast, 'forest cover' refers to the actual area that is covered by forests, characterized by the presence of tree canopy. Forest cover is a measure of the actual extent of forested land, while forest area is a legal or administrative classification.

Question 3 (i)

What steps have been taken up to conserve forests?

Solution: India has undertaken several steps to conserve its forests, especially after gaining independence. A significant step was the formulation of the Forest Policy of 1952, which emphasized sustainable forest management to conserve and expand forest resources while meeting local needs. Recognizing the need for more robust measures, a new National Forest Policy was adopted in 1988. This policy aimed to halt the decline in forest cover and set an ambitious goal of bringing one-third of the country's geographical area under forest cover. These policies guide the sustainable management and conservation of India's vital forest ecosystems.
