Tropical Evergreen 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 do best where there is a
short dry season and more than 200 cm of rainfall each year.
Tropical Deciduos Forest
They are also

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.
These forests are further
divided into moist and dry deciduous.
Montane Forest
In mountainous areas, the decrease in temperature with increasing altitud e leads to the corresponding change in natural vegetation. The wet temperate type of forests is found between a height of 1000 and 2000 meters.
