It embraces evergreen and semi-evergreen forests, moist deciduous monsoon forests, riparian forests, swamps and grasslands. Evergreen forests are found in the Assam Valley , the foothills of the eastern Himalayas and the lower parts of the Naga Hills , Meghalaya, Mizoram and Manipur , where the rain fall exceeds 2,300 mm (91 in) per annum.
However, tropical forests are extensive, making up just under half the world's forests. [3] The tropical domain has the largest proportion of the world's forests (45 percent), followed by the boreal, temperate and subtropical domains. [4] More than 3.6 million hectares of virgin tropical forest was lost in 2018. [5] [6]

Tropical rainforests are tropical evergreen mesophyll closed-canopy forests. Humid evergreen rainforest is mostly limited to northeastern Queensland. These forests are species-rich, with hundreds of tree species growing in Queensland's Wet Tropics , and no one species dominates the canopy.
Tropical rainforests have existed on earth for hundreds of millions of years. Most tropical rainforests today are on fragments of the Mesozoic era supercontinent of Gondwana. [13] The separation of the landmass resulted in a great loss of amphibian diversity while at the same time the drier climate spurred the diversification of reptiles. [10]
