The growth of vegetation depends mainly on the climatic conditions,
especially temperature and rainfall. We have already studied about the

variations in the climatic conditions. Accordingly, the vegetation also
varies greatly from one region to another. Depending upon the climatic

conditions and other factors, the forests in India can be classified into
five different types.

� Evergreen Forests � Deciduous Forests � Thorn Forests

� Tidal Forests � Mountain Forests

Evergreen Forests

Evergreen forests are found in hot and
humid areas where the annual rainfall

is more than 200 cm. The trees in these
forests do not shed their leaves altogether

at the same time. They remain green even
during the dry season. The important

evergreen trees are rosewood, ebony
and mahogany. Evergreen forests are Evergreen forest

found along the rainy slopes of the
Western Ghats, Andaman and Nicobar Islands and the hills of north-
