Mangroves are various large and extensive types of trees up to medium height and shrubs that grow in sediment habitats in the tropics and subtropics – mainly between latitudes 25° N and 25° S. The remaining mangrove forest areas of the world in 2000 was 53,190 square miles (137,760 km²) spanning 118 countries and territories.
The word is used in at least three senses: (1) most broadly to refer to the habitat and entire plant assemblage or mangal for which the terms mangrove forest biome, mangrove swamp and mangrove forest are also used, (2) to refer to all trees and large shrubs in the mangrove swamp, and (3) narrowly to refer to the mangrove family of plants, the , or even more specifically just to mangrove trees of the genus
The mangrove biome, or mangal, is a distinct saline woodland or shrubland habitat characterized bydepositional coastal environments, where fine sediments (often with high organic content) collect in areas protected from high-energy wave action. The saline conditions tolerated by various mangrove species range from brackish water, through pure seawater (30 to 40 ppt (parts per thousand)), to water concentrated byevaporation to over twice the salinity of ocean seawater (up to 90 ppt).
