These forests are found in the areas of quite high temperature and rainfall. The forests are dense, multi-layered and have many types of trees, shrubs and lians. These forests are further categorized into 4 types depending on the degree of wetness in the area and the dominant life form in the forest. (1) Tropical moist evergreen forests
These are climatic climax forests found commonly in areas having annual rainfall above 250 cm and temperature 25-30oC. These forests are chiefly distributed on the western face of Western Ghats, Assam, Cachar, parts of West Bengal, northern Canara, Annamalai Hills and Coorg in Meysore and Andman Islands. The characteristic feature of these forests is dense growth of very tall trees having height of more than 45 m. Climbers, lians, epiphytes and shrubs are abundant but herbs and grasses are rare in these forests. The carpet layer of herbs and grasses can not grow because very dense layer of leaf canopy of trees does not allow enough light to reach to the ground.
Dominant trees in forests of west coast are Dipterocarpus indica, Palaquim and Cellenia while in forests of AssamDiptercarpus macrocarpus, D. turbinatus, Shorea assamica, Mesua ferrea and Kayea are the dominant trees. Common subdominants in these forests are Mangifera, Eugenia, Myristica, Pterospermum, Polyalthia, Elaeocarpus, Schlechera, Artocarpus, Memeocylon, Poeciloneuron, Cinnamomum, Diospyros, Sapindus, Vitex, Holigarna, Alstonia, Hardwickia, Spondias, Dendrocalamus, Calamus, Bombax, Veteria, Calophyllum, Pandanus, Cedrela, Tetrameles, Strobilanthes, Emblica, Michelia, Ixora, Hopea, Lagerstroemia, several species of ferns and orchids. (2) Tropical moist semi-evergreen forests
These are also climatic climax forests found commonly in areas of annual rainfall 200-250 cm and temperature 25-32oC.These forests are chiefly distributed along the Western Ghats, in upper parts of Assam and Orissa and in Andman Islands. These forests are more developed in the northern India than in southern India. Characteristic feature of these forests is dense growth of evergreen trees intermixed with deciduous trees that shed their leaves for very brief period of relative dryness. Average height of trees in these forests is 25-35 m and shrubs are common. Forests have rich carpet layer of herbs, grasses ferns and orchids.
