The Pantanos de Centla (Centla swamps) is a tropical moist forest ecoregion in southern Mexico, which includes seasonally flooded forests and wetlands, in the summer.
Setting
The ecoregion covers an area of 17,200 square kilometers (6,600 sq mi) in the states of Tabasco and Campeche. The Centla swamps occupy the delta of the Usumacinta and Grijalva rivers, which empty into the Gulf of Mexico and the Laguna de Términos through numerous distributaries. The ecoregion includes year-round wetlands, and freshwater swamp forests which are inundated during the summer rainy season.
The Usumacinta mangroves lie in the brackish-water zone between the Centla swamps and the open water of the Laguna de Términos and the Gulf. The Petén-Veracruz moist forests lie to the west and south, and the Yucatan moist forests lie to the east.
Flora
The largest plant community in the ecoregion is semi-evergreen forest. Wetland plant communities, including marshlands and freshwater swamp forests, cover over a third of the region.
The predominant trees in the semi-evergreen forest include black olive tree (Bucida buceras) and logwood (Haematoxylum campechianum), with Spondias mombin, Tabebuia rosea, Lonchocarpus hondurensis, bitter angelim (Vatairea lundelii), gumbo-limbo (Bursera simaruba), guanandis (Calophyllum brasiliense), mahogany (Swietenia macrophylla), and cedar (Cedrela odorata).[3]
Fauna
Some large animals in the ecoregion include Morelet's crocodile (Crocodylus moreleti), jaguar (Panthera onca), mantled howler monkey (Alouatta palliata), and tropical gar or pejelagarto (Atractosteus tropicus).[4]
230 species of birds have been recorded, of which 63% are permanent residents, 23% winter residents, 4% transitory, and 10% do not have a defined seasonality.[4] The ecoregion's wetlands are home to many water birds, including jabiru stork (Jabiru mycteria), Maguari stork (Ciconia maguari), boat-billed heron or páspaque (Cochlearius cochlearius), ruddy ground dove (Columbina talpacoti), Muscovy duck (Cairina moschata), black-bellied whistling duck (Dendrocygna autumnalis), pied-billed grebe (Podilymbus podiceps), peregrine falcon (Falco peregrinus), and white ibis (Eudocimus albus).[3]
Conservation and threats
A 2017 assessment found that 5,644 km², or 33%, of the ecoregion is in protected areas.[1] The largest protected area is Pantanos de Centla Biosphere Reserve, which was established in 2006.
