The swamp is the association ecological vegetable of areas brackish, salted intermareales. Humedal of the interface earth, river and sea. Two terms: mangrove = tree and swamps = forest. At level mundias there are 80 species, 30 goods and 20 families. In america there are 15 species approximately. The body of the swamp includes, the vegetables, the floor, the body of water, the animal and human communities.

The dynamics of these ecosystems this certain one for a series of marine and terrestrial factors, as the local climate, the geomorphology, the salinity, the frequency and duration of the floods and the distance to the sea, characteristic that in turn determine in great measure the distribution of the species and their successions in the terrestrial geology.

In terms of productivity, the swamps are productive ecosystems that provide an important variety of fishing recurcos, forest resources and millions of birds residents and migratory, as well as mammals and reptiles.

To these ecosystems you/they is usually called also hydrophilic forests because for their coastal location they are always in direct contact with bodies of water of marine origin in combination with the water that arrives through the escorrentias or for the outlet of the rivers. He/she is also defined to the swamps like systems natural estuaries, where they happen the larval stages of marine countless species and of brackish water.

The swamps are dominated by a group of typically arboreal species that you/they have developed physiologic, reproductive and structural adaptations that allow them to colonize unstable sustratos and waterlogged areas, subject to changes of the tides of the tropical and subtropical costs protected by the surf.

Here, hoist them they possess certain structures specialized in their leaves (hidatodos) and in the roots (lenticelas and pneumatoforos) that allow them to eliminate the excess of salt, to survive and to be developed in waterlogged (flooded and inundables) lands, poor in I oxygenate and that they are subject to intrusions of salted or brackish water.
