Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the tropics of Cancer and Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of ...
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones.
Amazon River rain forest in Peru. Tropical rainforests are hot and wet. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year. [4] Average annual rainfall is no less than 1,680 mm (66 in) and can exceed 10 m (390 in) although it typically lies between 1,750 mm (69 in) and 3,000 mm (120 in). [5]
Forests account for 75% of the gross primary production of the Earth's biosphere, and contain 80% of the Earth's plant biomass. Net primary production is estimated at 21.9 gigatonnes of biomass per year for tropical forests, 8.1 for temperate forests, and 2.6 for boreal forests.
Rainforests are forests characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described.
Mangrove forests are the only woody halophytes that live in salt water along the world's subtropical and tropical coastlines. Mangroves are one of the most productive and ecologically important ecosystems on earth. The rates of primary production of mangroves equal those of tropical humid evergreen forests and coral reefs.

Tropical dry broadleaf forests are territories with a forest cover that is not very dense and has often an unkempt, irregular appearance, especially in the dry season. [8] This type of forest often includes bamboo and teak as the dominant large tree species, such as in the Phi Pan Nam Range, part of the Central Indochina dry forests. [9]
Tropical evergreen forests of India are found in the Andaman and Nicobar Islands, [a] the Western Ghats, [b] which fringe the Arabian Sea, the coastline of peninsular India, and the greater Assam region in the north-east. [c] Small remnants of semi-evergreen forest are found in Odisha state. [d] Semi-evergreen forest is more extensive than the ...
