Rain Forests occur in the areas which receive heavy rainfall. They are so dense
that sunlight doesn’t reach the ground. Many species of trees are found in
these forests, which shed their leaves at different times of the year.

and are found in the states of Rajasthan, Punjab, Haryana, Eastern slopes of
Western Ghats and Gujarat.
wide range of species is found in the mountains according to the variation in

1500 metres and 2500 metres most of the trees are conical in shape. These trees
are called coniferous trees. Chir, Pine and Deodar are important trees of these
forests can survive in saline water. They are found mainly in Sunderbans in West
