Tropical rainforest
Rainforest vegetation grows along the northern coast of Ecuador.
Tropical rainforests are characterized by high levels of annual precipitation, typically exceeding 1,800 to 2,500 mm (about 70 to 100 inches) per year. This rainfall is generally distributed fairly evenly throughout the year, which is a key factor in maintaining the tropical rainforest ecosystem.1
