Tropical and subtropical rainforests are the world’s powerhouses, the most vital habitats on the planet. Because they share many species and characteristics in common there is no clear cut boundary between tropical and subtropical rainforest. In general the subtropical rainforests have less of everything that is typically found in tropical rainforest.
One major difference is that a smaller number of that a smaller number of tree species from the canopy of subtropical rainforests.
Tropical and subtropical rainforests are characterized by very little variation in the high rainfall. These forests are found around the world particularly in the Indo-Malayan Archipelagos, the Amazon Basin, and the Africa Congo.
