The site fulfils all eight of the Ramsar Criteria and is considered one of the most important wetlands in Argentina and in the Chaco ecoregion in terms of the richness of its biodiversity in a range from freshwater to very saline. A number of species meet the waterbird Criteria, including Egretta thula (400,000 individuals), Phalaropus tricolor (200,000), Phalacrocorax olivaceus (42,000), Bubulcus ibis (60,000), and Plegadis chihi (400,000), and at least 4 species above the 1% threshold.
