An area of the Amazon rainforest in Brazil. The tropical rainforests of South America contain the largest diversity of species on Earth. [1] [2] Tropical rainforest climate zones (Af). Tropical forests: from the UN FRA2000 report. Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10° north and south ...
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. [ 1 ] [ 2 ] [ 3 ] In forest ecology , the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes , lianas , arboreal animals , etc.).

Many migratory birds and butterflies spend winter in tropical and subtropical conifer forests. This biome features a thick, closed canopy which blocks light to the floor and allows little underbrush. As a result, the ground is often covered with fungi and ferns. Shrubs and small trees compose a diverse understory. [1]
Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. [2] Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. [3]
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.
Seasonal tropical forest, also known as moist deciduous, semi-evergreen seasonal, tropical mixed or monsoon [1] forest, typically contains a range of tree species: only some of which drop some or all of their leaves during the dry season.
The Neotropic includes more tropical rainforest (tropical and subtropical moist broadleaf forests) than any other realm, extending from southern Mexico through Central America and northern South America to southern Brazil, including the vast Amazon rainforest. These rainforest ecoregions are one of the most important reserves of biodiversity on ...
