Ecuasal Salt lakes at Salinas city.
The salt lakes were created by man in the 1950´s by Ecuatoriana de Sal y Productos Químicos C.A.. The lakes have an extension of 1,500ha and are comprised of large sized cristalization and evaporation ponds divided by sand dikes. Ecuasal salt lakes are an artificial ecosystem characterized by a salinity gradient where invertebrate communities flourish in the absence of predators, and shorebirds are the only vertebrates that feed upon them. This is the reason the salt lakes have become an important stop-over- site for migratory shorebird populations of 19 species that breed in the artic region of the Americas. A conservation project of the aquatic bird fauna has been running since 2007 which focuses on research and monitoring of bird populations, outreach, environmental education and conservation management. Among the highlights found at Ecuasal are Chilean Flamingos, South American Terns, Gull-billed Terns, Wilson´s Phalaropes, Roseate Spoonbills and a diversity of shorebirds.
