Natural Vegetation

Teak: The major expansion of Teak trees is found in Central India i.e. Madhya Pradesh, Chhattisgarh and Odisha.
Deodar: Cedrus deodara is a species of cedar native to the western Himalayas at an elevation of 1500-2500 meters.
Sundari: It is the dominant mangrove tree species of the Sundarbans of Bangladesh and India.
Cinchona: The Cinchona is plant of Himalayan terai (tarai) region.

The description of forest regions found in India is given below:

Tropical moist deciduous forest: These forests are found in areas of moderate rainfall of 100 to 200 cm per annum therefore they are known as monsoon forests. Such areas include a belt running along the eastern slopes of Western Ghats. North eastern region of the peninsular India and Bhabar and Tarai (Terai) regions.

Tropical dry deciduous forest: The dry deciduous forests are mainly situated in the areas, where annual rainfall ranges from 70-100 cm. These are spread from central Gangetic plains to southern India.

Alpine Forest: The Alpine forests grow all along the Himalayas at altitudes ranging between 3,000 to 4,900 meter. The expansion of this forest is found in Arunachal Pradesh.

Tropical Evergreen Forests: These are typical rain forests which grow in those areas where the annual rainfall exceeds 200 cm. The evergreen forests are found along the Western side of the Western Ghats (The Sahyadri) North-East and in the Andaman and Nicobar Islands. Thus, option (a) is the correct answer.

The correct match of list-I and list-II is as follows:

Above mentioned features are related to tropical thorn forests. These forests are found in areas of low rainfall (less than 70 cm), low humidity (less than 50 per cent) and high temperature (25°-30°C). Western Andhra Pradesh is a region of such forests. These forests are found in the north-western parts of the country including Rajasthan, South Western Punjab, Western Haryana, Kutch and neighbouring parts of Saurashtra. Thus, option (d) is the correct answer.

Deodar trees are found at the highest elevation of 1500- 2500 meters above sea level in western Himalayas. Detail of other plants is as follows:

Chirr: It is native to the Himalayas and found at an elevation of between 900 to 1000 m.

Sal: It is mainly found in sub-Himalayan regions, eastern region of Central India and Tamil Nadu.

Teak: These trees are mainly found in Madhya Pradesh. Chhattisgarh, Odisha, Karnataka, Tamil Nadu, Gujarat & Maharashtra.

The place marked '3' in the map is the Sal forests which were threatened in 1997 by a serious epidemic. These got infected from a tree pest which weakened trees resulting in forest loss.

tropical dry deciduous forest or Sub Tropical forests expansion is found in most parts of Madhya Pradesh. Climatic Conditions:
Annual rainfall of 100 cm [mostly from the north-east monsoon winds in October - December]. Mean annual temperature is about 28°C. The mean humidity is about 75 per cent. The growth of evergreen forests in areas of such low rainfall is a bit strange.
Characteristics:
Short statured trees, up to 12 m high, with complete canopy. Bamboos and grasses not conspicuous. The important species are jamun, tamarind, neem, etc. Most of the land under these forests has been cleared for agriculture or casuarina plantations.

Originally, Mahogany trees are found in tropical region of North & South America. this tree is abundant in West Indies, Central America & South America. Rest trees are essentially a species of Himalayan vegetation.

An example of a multipurpose tree used in social forestry is Khejri. This tree is known as 'king of the desert'. The wood of Khejri is a good source fuel and provides excellent charcoal plus firewood, fodder, green manure and goat-proof thorny fences. Khejri is frost-resistant, drought resistance and withstands in wild temperature extremes. It requires minimum rainfall. That's why Khejri is the preferred plant species for social forestry programme.
