Dominant pattern of forest growth

Over most of India the controlling factor in the growth of natural vegetation is rainfall. Under normally moist conditions, there is fairly smooth transition from a tall, two storied or multistoried, tropical evergreen rain forest, in areas with over 200cm of annual precipitation, to an open thorny scrub and low bush, in areas with under 50cm. Between these extremes are a fairly dense deciduous and evergreen complex, in areas bordering on rain forests and deciduous tropical monsoon forests usually found in the peninsular hill sides.
