. Describe the principal features of the tropical rain (evergreen) forests.
(i)The tropical rain (evergreen) forests are restricted to heavy rainfall areas, that is, areas having more than 200 cm of rainfall with a short dry season.
Examples: The Western Ghats, the island groups of Lakshadweep, Andaman and Nicobar, the upper parts of Assam and the Tamil Nadu coast.
(ii)The trees reach great heights; up to 60 metres or even above.
(iii)Since the region is warm and wet thought the year, it has a luxuriant vegetation of all kinds-trees, shrubs, and creepers-giving it a multi-layered structure.
(iv)There is no definite time for trees to shed their leaves. As such, these forests appear green all the year round.
(v)Some of the commercially important trees of this forest are ebony, mahogany, rosewood, rubber and cinchona.
