Mangrove Mangroves are a kind of ecosystem often considered a type of biome, consisting of trees very salt tolerant occupying the intertidal zone near the mouths of freshwater streams from the coasts of tropical latitudes of the Earth. Thus, among the mangrove areas include estuaries and coastal areas. They have an enormous biodiversity with high productivity, being both a large number of bird species such as fish, crustaceans, molluscs, etc.. Its name comes from trees that form, mangroves, where the word is derived mangrove mangrove (in German, French and English) is originally Guarani and means twisted tree. Barrier is usually given as reasons for development, coastal erosion has been rapid. They also provide habitat for numerous species, provide natural protection against disasters like strong winds, waves produced by hurricanes and even tsunamis (see article on this).To these ends are made of mangrove plantations in coastal areas of Vietnam, Thailand, the Philippines and India. Mangroves are habitats (sets of habitat) in tropical and subtropical amphibians (water and land features) located in the intertidal zone (between high and low tide), protected coastal or low exposure-gulfs and bays, marshes and estuaries and mouths of rivers with soft bottoms (sand, silt or clay, never rock) and who regularly receive freshwater runoff. Mangroves are characterized by the predominance, in a given site, a few species of a cohort of 20 genera and 54 species of trees (mangroves) belonging to very different families (16), which are associated with many other plant species herbaceous and woody all have in common property to tolerate extremes of salinity and low oxygen tensions in water and soil, and they have evolved special physiological or anatomical adaptations.Mangroves play a key role in coastal protection against erosion by wind and waves. They have high productivity, host large numbers of aquatic organisms, amphibians and terrestrial habitat for the juvenile stages of hundreds of species of fish, molluscs and crustaceans and therefore play a vital role in coastal fisheries and the continental shelf. They are temporary habitat for many migratory bird species north and south. They represent an irreplaceable resource in the wood industry (wood heavy, very long, long fiber and resistant to moisture) and employees curtimbres tannins and dry cleaning.
