Tropical and subtropical moist broadleaf forests
Encyclopedia
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forests, are a tropical and subtropical forest
biome
.
Tropical and subtropical forest regions with lower rainfall are home to tropical and subtropical dry broadleaf forests
and tropical and subtropical coniferous forests
. Temperate rain forest
s also occur in certain humid temperate coastal regions.
The biome includes several types of forests:
Tropical and subtropical moist broadleaf forests are common in several terrestrial ecozone
s, including parts of the Afrotropic
(equatorial Africa
), Indomalaya
(parts of the Indian subcontinent
and Southeast Asia
), the Neotropic
(northern South America
and Central America
), Australasia

), and Oceania
(the tropical islands of the Pacific Ocean
). About half of the world's tropical rainforests are in the South American countries of Brazil
and Peru

s now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests.
