Types of Forests in India (Class 11 Geography, India: Physical Environment, Chapter 5, Natural Vegetation)
Updated 17 October 2026 · Fact-checked
Natural vegetation is a plant community left undisturbed for a long time so that it adjusts to climate and soil. India has five forest groups: tropical evergreen and semi-evergreen (over 200 cm rain), tropical deciduous (70 to 200 cm, the most widespread), tropical thorn (below 50 cm), montane, and littoral and swamp forests including mangroves.
Understand Five Types of Forests of India: Evergreen, Deciduous, Thorn, Montane and Mangroves
Why this topic matters. The rainfall, species and location of each forest type are tested as comparison tables and map work.
1. Natural vegetation. A plant community left undisturbed over a long time, so its species adjust as fully as possible to climate and soil. Plants grown in a garden or orchard are not natural vegetation. India shows temperate vegetation on Himalayan heights, tropical rainforests in the Western Ghats and Andaman and Nicobar, mangroves in the deltas and cacti and thorny bushes in Rajasthan. Under British rule the protective use of forests became commercial: oak forests of Garhwal and Kumaon gave way to chir pine for railways, and forests were cleared for tea, coffee and rubber.
2. Tropical evergreen and semi-evergreen. Western slopes of the Western Ghats, hills of the north-east and the Andaman and Nicobar Islands; rainfall over 200 cm and mean temperature above 22 degrees C. Evergreen forests are stratified, with trees up to 60 m or more, and are green all year; species include rosewood, mahogany, aini and ebony. Semi-evergreen forests mix evergreen and moist deciduous trees (white cedar, hollock, kail).
3. Tropical deciduous (monsoon). The most widespread forests, with 70 to 200 cm of rain. Moist deciduous (100 to 200 cm): teak, sal, shisham, hurra, mahua, amla, semul, kusum, sandalwood; found in the north-east along the Himalayan foothills, the eastern slopes of the Western Ghats and Odisha. Dry deciduous (70 to 100 cm): tendu, palas, amaltas, bel, khair, axlewood; trees shed all leaves in the dry season and the forest looks like a parkland or grassland.
4. Tropical thorn. Rainfall below 50 cm; semi-arid parts of Punjab, Haryana, Rajasthan, Gujarat, MP and UP; leafless most of the year; babool, ber, wild date palm, khair, neem, khejri, palas, with tussocky grass up to 2 m.
5. Montane forests. Temperature falls with altitude, so vegetation changes. Himalaya: deciduous at the foothills, wet temperate oak and chestnut at 1,000 to 2,000 m, pine (chir pine) at 1,500 to 1,750 m, deodar in the west, blue pine and spruce at 2,225 to 3,048 m, alpine forests and pastures at 3,000 to 4,000 m (silver fir, juniper, pine, birch, rhododendron), then mosses and lichens. South-facing slopes are thicker than north-facing. In the south (Western Ghats, Vindhyas, Nilgiris) temperate forests are called sholas.
6. Littoral and swamp. Wetlands cover 3.9 million hectares, about 70 per cent under paddy; Chilika Lake and Keoladeo National Park are Ramsar sites. Mangroves grow in salt marshes, tidal creeks, mud flats and estuaries; India has 4,992 sq km, 7 per cent of the world total, best in the Andaman and Nicobar Islands and the Sunderbans and in the Mahanadi, Godavari and Krishna deltas.

Example 3: Evergreen forest features · 3 marks · Short answerHarder board level
Describe the structure and climate of tropical evergreen forests. (3 marks)
Try it first, then show the solutionSolution
- Warm, humid, rainfall over 200 cm, temperature above 22 degrees C (1 mark).
- Well stratified, with shrubs and creepers, short trees, then tall trees up to 60 m or more (1 mark).
- No fixed leaf-fall time, so green all year (1 mark).
Answer: They grow in warm, humid areas with more than 200 cm of rain and mean annual temperature above 22 degrees C. The forest is stratified into shrubs and creepers near the ground, short trees and tall trees up to 60 m or more. Trees have no definite time for leaf fall, so the forest stays green all year.

Example 5: HOTS: why shola forests in the south · 5 marks · Long answerHOTS / competency
A student asks why temperate forests called sholas grow in the higher reaches of the Nilgiri, Anaimalai and Palani hills, which lie near the tropics. Explain the answer, name the species and compare with the northern Himalayan montane forests. (5 marks)
Try it first, then show the solutionSolution
- Temperature falls with altitude, so higher parts are temperate (1 mark).
- Lower parts remain sub-tropical (1 mark).
- Sholas occur in the Nilgiri, Anaimalai and Palani hills; species include magnolia, laurel, cinchona, wattle (1 mark).
- The Himalayas are far higher and extend to the snowline, so they show a full succession from tropical to tundra vegetation (1 mark).
- The southern hills show only sub-tropical forest below and temperate sholas above, so they have fewer zones than the Himalayas (1 mark).
Answer: Because temperature falls with height, the higher parts of the southern hills are temperate even though they lie near the tropics, while the lower parts remain sub-tropical. The temperate forests are called sholas and include magnolia, laurel, cinchona and wattle. The Himalayas are much higher, so they show a complete succession from tropical forest through oak, pine, fir and alpine forests to mosses and lichens.
Where students lose marks in Five Types of Forests of India: Evergreen, Deciduous, Thorn, Montane and Mangroves
The slips examiners see most often, and what to write instead.
Mistake: Giving wrong rainfall to forest types
Ranges mixed.
Wrong working
Moist deciduous: 70 to 100 cm.
Right working
Moist: 100 to 200 cm; dry: 70 to 100 cm.
Do this: Use the ladder 200-100-70-50.
Usually costs: 1 mark.
Mistake: Calling mangroves freshwater forests
Wetland word confusion.
Wrong working
Mangroves grow in fresh water.
Right working
Mangroves grow in salt marshes, tidal creeks and estuaries.
Do this: Link with salt-tolerance.
Usually costs: 1 mark.
Mistake: Saying evergreen trees never shed leaves
Misreading the term.
Wrong working
Evergreen trees never lose a leaf.
Right working
They have no definite time for leaf fall, so the forest is green all year.
Do this: Say "no definite time".
Usually costs: 1 mark.
Exam tips
- Make a table with rainfall, region, species and feature for the five types.
- Name at least two species for every forest type.
- For montane forests list zones from the foothills upward with altitudes.

Moist deciduous forests receive 100 to 200 cm of rain and occur in the north-east, the eastern Western Ghats and Odisha, with teak and sal. Dry deciduous forests receive 70 to 100 cm and occur in the rainier parts of the Peninsula and the plains of UP and Bihar, with a parkland look and trees like tendu and khair.
Q4 · 3 marks · Short answerHarder board level
How did British colonial policy change the use of forests? Give two examples. (3 marks)
Hint
Protective to commercial.
Answer
The protective use of forests was replaced by commercial use. Oak forests in Garhwal and Kumaon were replaced by chir pine to supply railway lines, and forests were cleared for tea, coffee and rubber plantations.
Q5 · 4 marks · Short answerHOTS / competency
Western and southern Rajasthan have very scanty forest cover although thorn forests are natural there. Give the climatic reason and one human cause, with typical species. (4 marks)
Hint
Low rainfall.
Answer
Rainfall is below 50 cm, so only scrub with leafless plants and tussocky grass can grow; the chapter also names overgrazing as a cause of scanty cover. Typical species are babool, ber, khejri and wild date palm.
