Natural vegetation refers to a plant community which has grown naturally without human aid. They have been left undisturbed by humans for a long time. We call this virgin vegetation.

The Climate of the Region
Temperature and humidity determine the character and extent of vegetation. The precipitation and soil also play a major role in determining the degree of vegetation. Therefore, various places in India have various vegetation patterns.
Photoperiod also affects the vegetation of a place. It is the variation in duration of sunlight at different places due to differences in latitude, altitude, season and duration of the day. Hence, depending on the photoperiod, you get different kinds of vegetation at different places. Now, we will look at the various types of vegetation.
Natural Vegetation of India
Types of vegetation
We have the following major types of vegetation in our country:
Tropical Rain Forests
These forests are restricted to heavy rainfall areas of the Western Ghats and the island groups of Lakshadweep, Andaman and Nicobar, upper parts of Assam and Tamil Nadu coast. They are at their best in areas having more than 200 cm of rainfall with a short dry season. The trees reach great heights up to 60 meters or even above. Some of the commercially important trees of this forest are ebony, mahogany, rosewood, rubber and cinchona.
Tropical Deciduous Forests
These are the most widespread forests of India. They are the monsoon forests and spread over the region receiving rainfall between 200 cm and 70 cm. Trees of this forest-type shed their leaves for about six to eight weeks in dry summer.
