The Gulf of Guayaquil–Tumbes mangroves (NT1413) are an ecoregion located in the Gulf of Guayaquil in South America, in northern Peru and southern Ecuador. It has an area of 3,300 km².
The Maranhão mangroves is a mangrove ecoregion of northern Brazil. It supports half of the shorebird population of the country. The combination of flat land, heavy rainfall and high tides causes the mangroves to extend up to 40 kilometres (25 mi) inland, where they are interspersed with other rainforest species.
The Guianan mangroves (NT1411) is a coastal ecoregion of southeastern Venezuela, Guyana, Suriname, French Guiana and Brazil. The mangroves provide an important habitat for migrating birds that winter in the area. Large areas are intact, although they are threatened by destruction of the trees for timber and to make way for agriculture, and from upstream agricultural and industrial pollution.
The Amapá mangroves (NT1402) is an ecoregion along the Atlantic coast of the state of Amapá in Brazil. The low coastal plain has been formed from recent sedimentation, including sediments deposited by the rivers and sediments carried northward from the mouth of the Amazon River by strong currents and deposited by the tides. The extensive mangroves grow on the newly formed coastal mudflats and along the edges of estuaries. They merge into freshwater várzea flooded forests further inland. The ecoregion is generally well-preserved, although excessive extraction of natural resources including timber and shrimps is a concern.
The Pará mangroves (NT1427) is an ecoregion along the Atlantic coast of the state of Pará in Brazil. They constitute the western extension of the Maranhão mangroves ecoregion. The mangroves are relatively intact, although they are under some pressure from agriculture and logging.
The South American Pacific mangroves, or Panama Bight mangroves, is an ecoregion along the Pacific coast of Panama, Colombia, Ecuador and Peru.
The Gulf of Panama mangroves (NT1414) is an ecoregion along the Pacific coast of Panama and Colombia. The mangroves experience seasonal flooding with high levels of sediment, and occasional extreme storms or very low rainfall due to El Niño effects. They are important as a breeding or nursery area for marine species. Areas of the mangroves have been recognized as Important Bird Areas and Ramsar wetlands. The ecoregion has been severely degraded by clearance of mangroves for agriculture, pasturage and shrimp farming, by urban pressure around Panama City, and by pollution related to the Panama Canal.
The Manabí mangroves (NT1418) is an ecoregion along the Pacific coast of Ecuador. The mangroves serve important functions in the marine and terrestrial ecology. They have been severely degraded and fragmented, particularly in the northern region. Construction of shrimp farms caused much damage in the past, but is now banned. Sedimentation caused by overgrazing in higher lands is an issue, as are human activities such as port and highway construction, urbanization, waste disposal and so on.
Cabo Corrientes is a cape on the Pacific coast of Colombia in the Chocó Department.
Rhizophora harrisonii is a species of plant in the family Rhizophoraceae. It can be found in Brazil, Cameroon, Colombia, Costa Rica, Ecuador, Guyana, French Guiana, Honduras, Nicaragua, Panama, Suriname, Trinidad, Tobago, and Venezuela.
The Bocas del Toro-San Bastimentos Island-San Blas mangroves ecoregion covers the mangrove habitats along the Caribbean Sea coast of Costa Rica and across the northern coast of Panama. An offshore reef and barrier islands of the region help protect the mangroves from destructive waves. The ecoregion has a high number of endangered and threatened species, including the loggerhead sea turtle, green sea turtle, and hawk's bill sea turtle.
The Coastal Venezuelan mangroves ecoregion covers the salt-water mangrove forests along the Caribbean Sea and Atlantic Ocean coast of Venezuela, from Cocinetas Basin to the edge of the Caño Manamo River and the Orinoco Delta in the east. It is one of the largest mangrove ecoregions in South America, with an area of 5,698 km2, and stretching across over 400 km of Venezuelan coastline.
The Gulf of Fonseca mangroves ecoregion covers the brackish mangrove forests around the Gulf of Fonseca on the Pacific Ocean. The Gulf is the meeting point El Salvador, Honduras, and Nicaragua. The Gulf is one of the two primary nesting sites of the critically endangered Hawksbill turtle in the eastern Pacific. In the Honduras portion, there are seven nature reserves that collectively make up a RAMSAR wetland of international importance, providing protection for migratory birds, sea turtle, and fish.
The Magdalena-Santa Marta mangroves ecoregion covers the mangrove forests along the coast of Colombia on the Caribbean Sea, from Gulf of Urabá in the west at the Colombia-Panama border to the Guajira Peninsula in the east. The region is relatively dry, with low precipitation and high evapotranspiration, so the mangroves depend for water and nutrients on the rivers flowing across the estuarine plain from the Sierra Nevada de Santa Marta mountains to the east. Efforts are currently underway to restore mangroves degraded by development and road building from the 1950s to 1980s.
The Mexican South Pacific Coast mangroves ecoregion covers the mangrove sites along the coast of the Pacific Ocean coast of Mexico, across the states of Michoacán, Guerrero, and Oaxaca. These mangrove forests are mostly around lagoons, typically those fed by rivers from the interior in the Sierra Madre del Sur Mountains. The ecoregion is small: collectively, it covers only 1,295 km2.
The Moist Pacific Coast mangroves ecoregion covers a series of disconnected mangrove sites along the Pacific Ocean coast of Costa Rica and Panama. These sites occur mostly on coastal flatlands around lagoons, particularly where rivers from the inland mountains reach the sea, bringing fresh water to the coastal forests. The area is in a transition zone from the drier coastline to the north; rainfall in this ecoregions is over 2,000 mm/year, and reaches over 3,600 mm/year at the southern end.
The Southern Dry Pacific Coast mangroves ecoregion covers a series of mangrove forests along the Pacific Ocean coast of Nicaragua and Costa Rica, from the southern margin of the Gulf of Fonseca to the Gulf of Nicoya near the border with Panama. Because the area is drier than the mangroves further south, evapotranspiration leaves some areas with higher salinity and even salt pans in the internal areas.
The Trinidad mangroves ecoregion covers the separate mangrove forest areas on the coast of the island of Trinidad, in the country of Trinidad and Tobago. The character of the mangroves is affected by the large amount of fresh water flowing out of the Orinoco River and Amazon River to the south, which flow northwest around the island. The mangroves of Trinidad are found on all coasts, and are usually in the estuaries of rivers, but also found in coastal lagoons.
The Tehuantepec-El Manchon mangroves ecoregion covers a series of mangrove woodlands along the Pacific Ocean coast of the state of Chiapas, Mexico. The ecoregion is relatively large and continuous, with trees up to 25 meters in height. The region supports stands of a type of yellow mangrove that normally only grown further south. The coast of Mexico here is wet - over 2,500 mm/year of rain. Four RAMSAR wetlands of international important are found in the zone, and a UNESCO Biosphere Reserve. Of particular importance are the wide variety of permanent and migratory birds in the area.
