Costero del Sur Biosphere Reserve, Biosphere reserve in Magdalena Partido, Argentina.
Costero del Sur Biosphere Reserve is a protected area stretching along the Rio de la Plata riverbank with wetlands and coastal dunes that form distinct estuarine habitats. These different environments support a wide range of bird and animal species throughout the year.
The area received legal protection in 1984 and UNESCO recognition shortly afterward. These designations marked an important turning point in the country's approach to environmental conservation.
People in nearby communities use the trails and waterways to watch and record wildlife as part of their regular routines. These everyday practices tie closely to the conservation goals of the area.
The reserve has marked trails and designated entry points to guide visitors safely while protecting the natural surroundings. It is important to stay on the marked paths and follow the posted guidelines throughout your visit.
The site contains ancient seabed deposits with shell ridges and cliffs that hold fossils from prehistoric marine periods. These rock formations tell the story of how the sea shaped this place thousands of years ago.
