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]
Borneo rainforest. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. [1] There is no single scheme that defines what a forest is, in tropical regions or elsewhere.
Tropical seasonal forests, also known as moist deciduous, monsoon or semi-evergreen (mixed) seasonal forests, have a monsoon or wet savannah climates (as in the Köppen climate classification): receiving high overall rainfall with a warm summer wet season and (often) a cooler winter dry season. Some trees in these forests drop some or all of ...
Biomes are often defined by their structure: at a general level, for example, tropical forests, temperate grasslands, and arctic tundra. [4]: 14 There can be any degree of subcategories among ecosystem types that comprise a biome, e.g., needle-leafed boreal forests or wet tropical forests.
Seasonal (mixed) tropical forests can be found in many parts of the tropical zone, with examples found in: In the Asia-Pacific region: seasonal forests predominate across large areas of the Eastern Java, Wallacea, Indian subcontinent and Indochina. Eastern Java monsoon forests; Wallacea Forest; Brahmaputra Valley semi-evergreen forests
Tropical rainforests provide timber as well as animal products such as meat and hides. Rainforests also have value as tourism destinations and for the ecosystem services provided. Many foods originally came from tropical forests, and are still mostly grown on plantations in regions that were formerly primary forest. [39]
The terms "tropical forest" and "rainforest" have largely replaced "jungle" as the descriptor of humid tropical forests, a linguistic transition that has occurred since the 1970s. "Rainforest" itself did not appear in English dictionaries prior to the 1970s. [ 22 ]
This indicates that tropical forest protected areas are becoming some of the last safe heavens for threatened species. [15] In the 1980s, the United Nations Food and Agriculture Organization conducted a study that concluded that 15.4 million hectares (100 acres) of tropical forest was lost per year. In addition, 5.6 million hectares were logged ...
