Tortuguero National Park is a national park in the Limón Province of Costa Rica. It is situated within the Tortuguero Conservation Area of the northeastern part of the country. Despite its remote location, reachable only by airplane or boat, it is the third-most visited park in Costa Rica. The park has a large variety of biological diversity due to the existence within the reserve of eleven different habitats, including rainforest, mangrove forests, swamps, beaches, and lagoons. Located in a tropical climate, it is very humid, and receives up to 250 inches (6,400 mm) of rain a year.
The Belizean Coast mangroves ecoregion covers the brackish and salt-water habitats along the Caribbean Sea coast of Belize, and of Amatique Bay in Guatemala; small parts in the border with Mexico are also present on this ecoregion. The mangroves are partially protected from the open sea by the Belize Barrier Reef, and this ecoregion is distinct from the reef-based Belizean Reef mangroves ecoregion offshore. There is a large population of the vulnerable West Indian manatee in the area. It covers an area of around 2850 km2.
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 Esmeraldas-Pacific Colombia mangroves (NT1409) is an ecoregion of mangrove forests along the Pacific coast of Colombia and Ecuador. It is threatened by human population growth, leading to over-exploitation for wood and clearance for farming and aquaculture.
The Mesoamerican Gulf-Caribbean mangroves ecoregion covers the series of disconnected mangrove habitats along the eastern coast of Central America. These salt-water wetlands are found in river deltas, lagoons, and low-lying areas facing the Gulf of Mexico and Caribbean Sea, from Tampico, Mexico to central Panama. The mangroves are areas of high biodiversity and endemism. Many of the sites are protected as national parks or nature reserves.
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 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 Northern Dry Pacific Coast mangroves ecoregion covers the mangrove habitats in a series of sites along the Pacific Ocean coast of Guatemala and El Salvador. This part of Central America is relatively dry compared to higher elevations or more southerly areas, so the wetland mangroves serve as a refuge for animals of the interior during the winter dry season. The mangroves only extend a few kilometers inland to where the salt water influence is gone; the ecoregion surrounding the mangroves is the Central American dry forests ecoregion.
The Mayan Corridor mangroves ecoregion covers the mangrove habitats along the Caribbean Sea coast of the state of Quintana Roo in southern Mexico and a narrow strip on the north of Belize. The region is named for the Maya Civilization archeological sites along the coast. Biodiversity in the area high due to the interactions of different environments - coastal lagoons, river estuaries, coral reefs, and barrier beaches. The ecoregion supports Mexico's largest population of crocodiles.
The Petenes mangroves ecoregion covers mangrove habitat along the Gulf of Mexico coast of southern Mexico, where Campeche state and Yucatan state meet, centering on the Celestun Lagoon inland from the barrier-island town of Celestún. Because the region has relatively little rainfall and no rivers feeding the lagoons, the freshwater to support the mangrove ecosystem springs from underground aquifers. The area is important for migratory birds, and as a nesting area for sea turtles. The area around the Celestun Lagoon is protected by the Ría Celestún Biosphere Reserve, a UNESCO Biosphere Reserve, and Los Petenes Biosphere Reserve in Campeche.
The Ría Lagartos mangroves ecoregion covers mangrove habitats of along the northern coast of the Yucatan Peninsula, including the Ria Lagartos Lagoon. A prominent section of the ecoregion is covered by the Ría Lagartos Biosphere Reserve. The site is an important area for migratory birds, fish, and sea turtles.
The Rio Piranhas mangroves ecoregion covers a series of mangrove forests along the Atlantic Ocean coast of the eastern tip of Brazil. The mangrove sections are spread across 350 km, from the mouth of the Mamanguape River in the north, to the vicinity of Maceió in the south. This coast is centered on the city of Recife, and the mangrove sections often surround industrial ports and cities.
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 Rio Sao Francisco mangroves ecoregion covers series of mangrove forests along the Atlantic Ocean coast of eastern Brazil, from the outskirts of Maceió southwards to just south of Salvador, Bahia. This ecoregion has high biodiversity, as it lies in different sub-climate zones, with a dry season in the north but not in the south.
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.
The Usumacinta mangroves ecoregion covers the mangrove forests ont the Gulf Coast of Mexico, around the margins of the Laguna de Términos. The "Ends" in the name refer to the mouths of the rivers that empty into the lagoon, including the Usumacinta River. This region, which is due south of the mouth of the Mississippi River across the Gulf of Mexico, receives an estimated one-third of the wintering birds migrating on the Mississippi Flyway. It is estimated that the lagoon supports 90 endangered species.
