Abstract
The Capital District of Bogotá has 15 wetlands recognized within the system of protected areas of the city, most of which are seriously affected due to the pressure exerted by the rapid urban growth. Unlike other systems of the same type, El Salitre wetland, recently declared as a Wetland District Ecological Park, has not been affected by wastewater discharges. In this study, we determined its trophic state based on the concentrations of nutrients and phytoplanktonic chlorophyll a, trophic state indices calculation and the taxonomic composition of phytoplankton. Nitrogen was the limiting nutrient. Low concentrations of nitrogen compounds, phytoplankton indices, and dominance of desmids (Conjugatophyceae) indicated that El Salitre wetland presented an oligotrophic to mesotrophic condition in the two climatic periods during which it was studied. These results suggest that it could serve as reference system for other wetlands in Bogotá. © 2017. Acad. Colomb. Cienc. Ex. Fis. Nat.References
