A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The term is also applied to tropical coastal vegetation consisting mainly of such trees. Mangroves occur worldwide in the tropics and subtropics, mainly between latitudes 25° N and 25° S.
Rainforest
A rainforest is a type of forest that is characterized by high rainfall, high humidity, and a dense canopy of trees. Rainforests are found in tropical and subtropical regions around the world.
Savanna
A savanna is a grassland ecosystem characterized by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an understory of grasses and other herbaceous plants.
Tropical evergreen forests
Tropical evergreen forests are characterized by a dense canopy of trees that retain their leaves throughout the year. These forests are found in areas with a warm, humid climate.
