“The mangrove is a biotic area or biome, formed by trees very tolerant to the salts existing in the intertidal zone near the mouth of freshwater courses in tropical and subtropical latitudes, areas with mangroves include estuaries and coastal areas. They have a great biological diversity, like many species of birds, fishes, crustaceans, mollusks and others.

Its name derives from the mangle trees that form them, the word mangle (from which mangrove derives in German, French and English) comes from a Caribbean or Arawak voice, perhaps Guarani and means twisted tree. usually they are given as a barrier in places that for reasons of development, the coast has undergone a fast erosion. They also serve as habitat for numerous species and provide natural protection against strong winds, waves produced by hurricanes and even by tsunamis.

Mangroves are tropical and subtropical biotopos (habitats), amphibian habitats (with aquatic and terrestrial characteristics), located in the intertidal zone (between high and low tide), protected or poorly exposed coasts-gulfs and inlets, marshes and estuaries or mouth of rivers – with soft bottoms (of sands, silts or clay, never rocky) and that receive periodically fresh water by runoff. Mangroves are characterized by a predominance of a few species of a cohort of 20 genera and 54 species of trees (mangroves) belonging to very diverse families (16), at a given site, to which many other plant species are associated Herbaceous and woody; All have in common the property of tolerating extreme conditions of salinity and low oxygen tensions in water and soil, for which have evolved with special physiological or anatomical adaptations.

Mangroves play a primary role in coastal protection against wind and wave erosion. They have a high productivity, they host large numbers of aquatic, amphibian and terrestrial organisms; Are generators of life, they are habitat of the juvenile stages of hundreds of species of fish, mollusks and crustaceans. They are too a temporary habitat for many species of northern and southern migratory birds. “(Wikipedia)

It is represented by a forest ecosystem, which is flooded periodically by the action of the tides and where there is an appropriate supply of sludge, rich in organic matter.

The Manglar Térraba Sierpe is the largest expanse of virgin mangrove forest in the Central American region, located on the South Pacific coast of Costa Rica, specifically in the Diquis Valley. it forms more than 50 acres of mangrove forests and flooded forests, full of exuberant biological diversity: more than 800 species of birds, like ospreys, red limpets and tiger heron, reptiles like crocodiles or caimans, several species of mammals like coatis, raccoons, squirrels, anteaters, standing out among them the four species of monkey that exist in Costa Rica which are the capuchin or carablanca, the howler, the squirrel and the spider, all residents of this enormous ecosystem, some species of passage, others endemic and unique in the world.

Due to its importance to the planet, it was declared as a RAMSAR site, this for the variety of flora and fauna both aquatic and terrestrial and for being a site of reproduction of important species of the terrestrial ecosystem.
