Question 34 Marks
State the types of forests in India. OR State the natural vegetation regions of India and give information about each of them.
Answer
There are five major types of forests in India: 1. Tropical Rainforests. 2. Tropical Deciduous Forests. 3. Tropical Desert Vegetation. 4. Temperate Forests and Grasslands (Himalayan Vegetation) and 5. Tidal (Mangrove) Forests.
1. Tropical Rainforests:
(i) Distribution: Such forests are found in the regions of hot and humid climate, with rainfall exceeding 200 cm and temperature 22 °C.
→These forests are found in the regions of heavy rainfall in Western Ghats, Lakshadweep and Andaman-Nicobar Islands, upper regions of Assam and coastal Tamil Nadu.
(ii) Trees: Mahogany, ebony, rosewood, rubber, etc. are major trees here.
(iii) Characteristics: (1) Here the trees are 60 metres tall or even higher. (2) There is more humidity due to scrubs. (3) There is no autumn season in these forests. (4) As the trees are evergreen, these are also called 'Evergreen Forests'. (5) The girth of the trees is very thick and the wood is also very hard and heavy.
2. Tropical Deciduous Forests:
(i) Distribution: These forests are found in India in the regions receiving rainfall between 70 to 200 cm in North-Eastern states, foothills of Himalayas. Western Odisha. Chhattisgarh, Jharkhand, eastern slopes of Western Ghats and Vindhya and Satpuda mountain ranges.
(ii) Trees: Teakwood, saal, sesame, sandal wood, kher, bamboo, etc. are important trees.
(iii) Characteristics: Here, the trees shed their
leaves completely for 6 to 8 weeks during autumn. So these are called 'Deciduous Forests'.
→The specific time to shed their leaves is different among the trees of all species. So the entire forest is never barren.
→As the trees shed their leaves according to the season, these are also called 'Monsoon Forests'.
3. Tropical Desert Vegetation:
(i) Distribution: These forests are found in the regions receiving less than 70 cm rain.
→These forests are found in Gujarat, Rajasthan, Madhya Pradesh. Uttar Pradesh, Haryana and some rain shadow area of Western Ghats.
(ii) Trees: Date, jujube, acacia, cactus, khijdo. etc.
(iii) Characteristics: The roots of these trees are long, deep and are spread like radius of a circle to procure water.
→Their leaves are shorter so the process of transpiration is slower.
→Trees in these forests are scattered.

4. Temperate Forests and Grasslands (Himalayan Vegetation) :
AltitudeAreal SpanForestsTrees
1000 to 2000 metres in HimalayasHigh mountains of north-east. West Bengal and mountainous area of UttarakhandTropical forestsOak and chestnut
1500 to 3000 metres in HimalayasSouthern slopes of Himalayas. higher area of south and north-eastConiferous forestsPine, saal, silver fir. spruce, cedar, etc
3600 metres and moreHigher altitudes in Himalayas and near the snowlineAlpine grass and tundra vegetationSilver fir, juniper. birch, etc.
Characteristics of coniferous forests: The trees here have conical shape.
→As the branches of the tree slope downward. the snow over the trees during the snow fall easily slides down over the land.
→The leaves are long, pointed and sticky. They can retain the humidity for a longer time.
→The wood of these trees is very soft and full of pulp from inside. So it is useful for paper making.
→It takes many years for these trees to develop.
5. Tidal (Mangrove) Forests:
(i) Distribution:
These forests are found in the deltas of the rivers near the seacoast.
→These are found in the coastal region of the Bay of Bengal (Sundarvan) and in the marshy area along the Gujarat coast on a small scale.
(ii) Trees: Main trees here are sundari and cher.
