Correct Answer: B. 20%

The correct answer is 20%. Forests cover approximately 21-24% of India's land. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: D. All

The correct answer is All. Teak, sal, and deodar forests are commercially valuable. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: C. Tropical Dry Deciduous

Tropical Dry Deciduous forests are the most widespread forest type in India, covering about 38% of the total forest area. These forests are found across large parts of central, northern, and peninsular India. They receive rainfall between 750-1500 mm annually. Teak and sal are the dominant tree species in these forests.

Correct Answer: B. Western Ghats and North-East India

Tropical Wet Evergreen forests are found in the Western Ghats and North-East India where rainfall exceeds 2000 mm annually. These forests are also called Tropical Rain Forests or Shola forests in the Nilgiris. They are characterised by dense canopy with trees like rosewood, ebony, and bamboo. India's highest biodiversity is found in these forest zones.

Correct Answer: B. Teak

Teak (Tectona grandis) is the most commercially important and dominant tree in Tropical Moist Deciduous forests. These forests receive rainfall between 1000-2000 mm annually and are found in peninsular India, Madhya Pradesh, and Odisha. Teak wood is valued for furniture, shipbuilding, and construction. India is one of the world's largest producers of teak.

Correct Answer: A. Trees shed leaves in summer

Tropical Dry Deciduous forests are characterised by trees shedding leaves in summer (dry season) to conserve water. This leaf-shedding adaptation helps the trees survive the long dry period from November to June. These forests receive rainfall between 750-1500 mm annually. Sal, teak, tendu, and axlewood are common trees in these forests.

Correct Answer: B. West Bengal and Odisha

Mangrove forests are most extensively found in West Bengal and Odisha in India. The Sundarbans in West Bengal is the world's largest mangrove delta, covering about 4,200 sq km on the Indian side. Odisha's Bhitarkanika Wildlife Sanctuary is the second largest mangrove ecosystem in India. These forests grow in tidal mudflats along the coast and river deltas.

Correct Answer: C. West Bengal

Sundarbans, the largest mangrove forest in India and the world, is located in West Bengal. It spans across India and Bangladesh with the Indian portion covering about 4,200 sq km. Sundarbans is a UNESCO World Heritage Site and is famous for the Royal Bengal Tiger. It lies in the Ganges-Brahmaputra delta and is protected under Project Tiger.

Correct Answer: A. Champion and Seth classification

The Champion and Seth (1968) classification is the most widely used system for classifying Indian forests. It identifies 16 major forest types and over 220 subtypes based on climate, soil, and vegetation. This classification replaced the earlier Champion (1936) classification by incorporating more detailed ecological parameters. It remains the standard reference for forest surveys and management in India.

Correct Answer: B. Alpine Forests

Alpine Forests are found in the Himalayan region above 3500 metres elevation where the tree line ends. These forests transition to alpine meadows (bugyals) and eventually to permanent snow above 5000 metres. Common trees include silver fir, rhododendron, and juniper at lower alpine elevations. These forests play a crucial role in protecting Himalayan watersheds and preventing soil erosion.
