Pantanos de Centla: Wetland Conservation
A Fall 2009 Bio 245 Conservation Biology Class Project
Written by Jon Wunderlich.
Pantanos de Centla is a terrestrial ecoregion in the Mexican state of Tabasco. Being mostly composed of wetlands, this region is one of the most important hydrological watersheds of Mesoamerica. The region is made up of three basins, the Usumacinta river basin, the Laguna De Terminos, and the Grijalva river basin (Vanega 2003). Protected flora resides here such as the red mangrove and mahogany. This ecoregion is home to the endemic Mexican gar fish and contains endangered species such as the jaguar, West Indian manatee, and the Central American river turtle (Vanega 2003 ; WWF 2001).

The protected and endemic organisms residing in the Pantanos de Centla is not the only important factor to consider. The region is made up mostly of wetlands and mangroves (WWF 2001), which serve as wildlife habitats and directly impact local human health. Wetlands assist greatly in many functions beneficial to humanity including flood control, groundwater recharge, nutrient removal, and toxics retention (Turner 2000 ; Barbier 1993). This ecoregion is threatened mainly because of the soil is among the most productive in all of Mexico (WWF 2001), which has resulted in a great deal of habitat loss due to human developments and continues to threaten this habitat today.
Threats to this Ecoregion include:
With the Pantanos de Centla biosphere being considered critically threatened, new and effective solutions to the above mentioned threats are needed to protect this ecoregion as well as the ecological and human benefits it provides. In conclusion we need to understand that the marginal benefits of conserving these natural wetlands greatly outweigh artificial alternatives.
