The Llobregat delta, with 98 km², is the second largest delta in Catalonia, only behind the Ebro delta. Throughout history this alluvial plain has had different river mouths, which over the years have created different coastal lagoons. These lagoons are of great importance for the nesting and migration of many birds. The growth of numerous human infrastructures have been surrounding and reducing the natural spaces of the delta, which have experienced a reduction in fauna and a degradation of their spaces.
