The Nature Reserve of the Endorreic Complex of Lebrija-Las Cabezas, together with that of Espera, are the last redoubt of a great lagoon system that ran through the entire countryside between Seville and Cadiz. Human activity has gradually reduced the wetland to the lagoons of La Cigarrera, Galiana, Peña, Pilón, Taraje (the only permanent one) and Charroao, known as Bujadillo or Herradura.
Like the rest of the wetlands located in the strip between the Baetic mountain range and the Guadalquivir Depression, this wetland area consists of three shallow lagoons: Zarracatín, Arjona and Alcaparrosa. Its seasonal nature makes it dependent on dependent of direct rainfall recharge; therefore, it is usually dry in the summer or during persistent drought.
The Laguna del Gosque is an endorheic and seasonal wetland. It is located on flat terrain, in an area of undulating relief and gentle hills, near the Sierra de los Caballos, in the south of the province of Seville.
The 20-hectare restored lagoon was declared as a natural reserve on 28 July 1989. Located about 800 metres from the village, endangered species such as white-headed duck, mallard or pink flamingo nest and roost here.
Escalera Lagoon, which belongs to the group of endorheic lagoons in the Lantejuela area, is a temporary wetland with high salinity. As with the other nearby lagoons, it stands out for its ornithological importance as a feeding area for flamingos and other birds.
It is an attractive place for ornithologists. February to April is the best time to visit, after the winter rains.
La Galiana Lagoon is a small, shallow wetland that is part of the Lebrija-Las Cabezas Endorheic Complex Natural Reserve.
The lagoon, located in gently sloping terrain, it is fed by surface runoff and direct rainfall. This leads to strong seasonality. It is the first lagoon in the complex that dries up. Its waters are sub-saline throughout the flooding cycle.
La Cigarrera is a small, sib-saline lagoon in the Lebrija-Las Cabezas Endorheic Complex Natural Reserve. This lagoon has the best-preserved strip of perilagoon vegetation in the complex.
