Introduction

You have probably walked through a forest on a picnic, or sat in a park in a city, or played under a mango, guava, or coconut tree in a village orchard. In each case, you are surrounded by plants.

Types of Forests

The natural vegetation of India is not a uniform green blanket. It changes with rainfall, temperature, altitude, and soil.

5.2.1

Tropical Evergreen and Semi Evergreen Forests

Tropical evergreen forests are the signature vegetation of the equatorial and warm tropical regions — dense, multi-layered, and green all year round.

5.2.2

Tropical deciduous forests are the most widespread natural vegetation type in India. Unlike the dense, evergreen rainforests that stay green all year, these forests shed their leaves for about six to…

Wildlife Conservation in India

5.6

Biosphere Reserves
