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.
This Special Conservation Area (SCA) covers some 4,772 ha, mostly in the province of Seville. This site features prominently in the Andalusian Natura 2000 network owing to its special importance for the conservation of riparian habitats, certain fish species included in the Habitats Directive and, in general, the river ecosystem and the connectivity it provides as an ecological corridor.
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.
This lagoon complex, located between Lantejuela and Osuna, is what remains of a vast 600-km2 wetland that extended until Ecija.
These nine lagoons have exceptional value because they are the last lagoons that remain of what used to be one of the most extensive wetlands in the Guadalquivir Depression.
