This municipal reserve includes open coastal environments adapted to high salt concentrations, where endangered species such as the Southern Flamingo (Phoenicopterus chilensis) and the Olrog’s Gull (Larus atlanticus) are present, along with a varied fauna of resident and migratory species. The area also has a very high educational potential due to its proximity to the city of Bahía Blanca. Jume marshes (Sarcocornia perennis) environments stand out.
