PANTANOS DE CENTLA

 
       
  General Description   The Reserve is located in the physiographic province “Llanura Costera del Golfo Sur” and the subprovince “Llanuras y Pantanos Tabasqueños”; here predominates the topographic formations of barrier plain (beaches) towards the coast, and over all the coastal floodplain. They are originated by the mouth of the Grijalva and Usumacinta Rivers.
Due to the wide vegetation coverage, Pantanos de Centla Biosphere Reserve (RBPC) is a potentially important area for the extraction of carbon. Currently, the Reserve safeguards 569 identified flora species, distributed among 118 families grouped in 8 main associations both monocotyledonous and dicotyledonous from the aquatic and terrestrial systems. These eight associations are a) hydrophyte communities (they occupy more than a third part of the Pantanos de Centla region, which makes them the best-developed and most extended formations within its boundaries, besides, it is estimated that the surface occupied by this type of vegetation in Pantanos de Centla Biosphere Reserve represents 11.27 % of the surface reported for Mexico; b) and c) the middle and low semi-evergreen gregorywood (Bucida buceras) and logwood (Haematoxylon campechianum) forests respectively, are found in the area as wide strips, patches and islets among the aquatic vegetation that borders them naturally; for their economic importance, the most significant species from these two associations are: hog plum, yellow mombin (Spondias mombin), pink trumpet-tree (Tabebuia rosea), cabbage-bark (Lonchocarpus hondurensis), bitter wood (Vatairea lundelii), gumbo limbo (Bursera simaruba), barí (Callophyllum brasiliensis), mahogany (Swietenia macrophylla), cedar (Cedrella odorata), among others.
The main economic activity of its inhabitants is coast fisheries, with production volumes that represent 19 % of all the production of the entity, stressing the use of the Cichlidae family and the lizardfish. They also use approximately 200 plant species and in order to fill their protein needs, they use the fauna that the local area offers, species such as chelonia, some anatidae, mammals like the Tepezcuintle, armadillo, deer, among others. Another important activity is backyard or crops where they develop poultry, agriculture and livestock activities (the main species are fowl, pig and cattle, corn, beans, pumpkin, banana, tomato, chili, cassava, sweet potato, melon, lemon, orange, spices, among others). Also, 21% of the gas taken from the Southeastern area of the country, is taken from this area.
