Tropical rainforest: Rainforest

Rainforest, luxuriant forest, generally composed of tall, broad-leaved trees and usually found in wet tropical uplands and lowlands around the Equator. Rainforests usually occur in regions where there is a high annual rainfall of generally more than 1,800 mm (70 inches) and a hot and steamy climate.

Learn about the importance, diversity and challenges of tropical forests, which cover 6% of the planet but host 80% of the world's species. WWF works to protect and restore these vital habitats and their ecosystem services. The tropical rainforest is one of the world’s most threatened biomes, despite being home to some of the most diverse and unique species on the planet.
