How do geographers define NATURAL VEGETATION?
NATURAL VEGETATION refers to plant cover that has developed WITHOUT human intervention — left undisturbed long enough that the species composition + structure represent a balance with local climate + soil. In practice, today, fully untouched natural vegetation is RARE — almost everywhere has been altered by agriculture, grazing, fire, or logging. Geographers contrast it with CULTIVATED (or planted) vegetation. The study of natural vegetation reveals how climate + soil + topography combine to support distinct ecosystems — tropical rainforest, savanna, desert, tundra, etc.
Five major Indian forest types per the standard textbook?
(i) Tropical Evergreen and Semi-Evergreen, (ii) Tropical Deciduous, (iii) Tropical Thorn, (iv) Montane, (v) Littoral and Swamp.
What broad factors determine vegetation type?
Climate (temperature + rainfall) and soil — together produce the variation across regions.
How did the British change Indian forest structure?
Replaced oak forests in Garhwal/Kumaon with pine (chirs) for railway sleepers; cleared forests for tea, rubber, and coffee plantations; used timber for construction (heat-insulating).
Where are tropical evergreen forests found?
Western slopes of Western Ghats, hills of NE India, Andaman and Nicobar Islands.
Climatic conditions for tropical evergreen?
Warm and humid; annual precipitation > 200 cm; mean annual temperature > 22 °C.
Why "evergreen"?
No definite time for shedding leaves, flowering or fruiting — always appear green.
Tree height in evergreen forests?
Trees can reach 60 m or more — well-stratified canopy with shrubs, creepers, short trees, then tall canopy.
Main tree species?
Rosewood, mahogany, aini, ebony.
Where are semi-evergreen forests found?
In the LESS rainy parts of the same regions (Western Ghats, NE, A&N).
Distinguishing feature of semi-evergreen?
Mixture of evergreen and moist deciduous trees; undergrowing climbers give an evergreen character.
Main species in semi-evergreen?
White cedar, hollock, kail.
