Tropical evergreen forests of India are found in the Andaman and Nicobar Islands, the Western Ghats, which fringe the Arabian Sea, the coastline of peninsular India, and the greater Assam region in the north-east. Small remnants of evergreen forest are found in Odisha state. Semi-evergreen forest is more extensive than the evergreen formation partly because evergreen forests tend to degrade to semi-evergreen with human interference. There are substantial differences between the three major evergreen forest regions.The average annual rainfall is 65-75 inches.
Dipterocarpus tuberculatus is a species of tree in the family Dipterocarpaceae found in Bangladesh, Myanmar, Thailand, Cambodia, Laos and Vietnam. The tree is found in clear forests of plains, at altitudes up to 800–1,000 m (2,600–3,300 ft). It grows to a height of 5–25 m (16–82 ft).
