Consists of 11 urban wetlands designated as District Ecological Parks. These permanent freshwater marshes provide shelter and habitat to endemic species from the High Andean region of Colombia, such as the Bogotá rail (Rallus semiplumbeus) and the Apolinar’s wren (Cistothorus apolinari). There are also records of 196 bird species, 42 of them aquatic and 65 migrant. This wetland complex regulates the supply of water from the rivers of the Bogotá savannah, providing flood control in the rainy season and in summer allowing for conservation of groundwater levels. It is a crucial ecological connector between the rural and urban territories of the Bogotá River basin, crossing the city of Bogotá from east to west. In addition, it is the first urban complex of High Andean wetlands in Latin America to be added to the List. The site has also been designated as an Important Bird Area (IBA). Among the main threats to the site are rainfall and climate variability associated with El Niño and La Niña events.
