The Ramsar Site includes the area surrounding two brackish water lagoons united by the Pantanillo-Cienaga Redonda biological corridor. The site acts as an important regulator of the biotic and abiotic elements forming the ecological web of this Andean ecosystem by supporting species such as the Andean gull (Larus serranus) and the Vicuña (Vicugna vicugna) catalogued as vulnerable under Chilean policy, as well as at least 1% of the total population of the Andean Flamingo (Phoenicoparrus andinus), James's Flamingo (Phoenicoparrus jamesi) and the Horned Coot (Fulica cornuta). There are vestiges of pre-Hispanic occupation in the surrounding area, as well as human activities which include water extraction for mining activities and tourism. The Ramsar Site has a management plan for the areas included in the Nevado Tres Cruces National Park. Ramsar Site no. 877. Most recent RIS information: 2011.
