A terrestrial biome found within 23.5° of the equator in areas where rainfall is abundant (more than 250 cm/year) and the dry season, if any, is brief. Forests are very diverse floristically and structurally; trees sometimes reach great heights. Most trees are evergreen; deciduous species, if present, do not all lose their leaves at the same time of year.

A biome composed primarily of evergreen broad-leaved trees growing in tropical areas of high rainfall throughout most of the year.

A warm, humid forest with at least 100 inches of rainfall a year, that is found around the equator in places like South America, Southeast Asia, and Africa. At least half of all the world’s animals—and millions of indigenous peoples—are found in the tropical rainforests. Tropical rainforests might disappear in our lifetime if we don’t act now to save them.
