These lagoons were declared Integral Reserves by the Andalusian Parliament in 1984, and in 1989, classified as Natural Reserves (Law 2/1989, of July 18, of inventory of Protected Natural Spaces). In addition, permanent waters have been a part of the Wetland Complex of International Importance under the Ramsar Convention since 1990, and are considered as a ZEPA (Special Protection Area for Birds) area by the European Union. In the municipality of Lucena we find several integral reserves that are within the protected area known as Lagunas del Sur (the Southern Lakes) de Córdoba, some of which observe a high ecological content to be wet for much of the year or always. It is also an area where the enjoyment of nature is very possible because the conservation conditions due to these lagoons, is still quite acceptable. In this way we highlight: Laguna Amarga located in the municipality of Lucena and near the village of Jauja, it has permanent brackish water, since it has a high concentration of magnesium sulphate, which gives it a bitter taste and hence its name. Its wide perilagunar belt, with a thickness between 2 and 9 meters, is enriched with the Taraje (bush) that serves as shelter for a large number of birds. In a kidney shape, it has a maximum depth of 4 m and a surface of 13 Hectares of Natural Reserve and 250 of protection. With a rich underwater vegetation composed of Coots, Grebes, Mallard, Red Duck, Common Duck, Tufted Duck, Anas Clypeata and of course, the Ruddy Duck and the Purple Gallinule, species these last two that are reproduced annually in its rich belt. Its environment is dedicated to agricultural work, mainly olives, with the exception of an area where rocks emerge and Mediterranean scrub grows. Laguna de Los Jarales is a small lagoon of temporary and brackish waters, which is located in the municipality of Lucena, on Oligocene land, within a wide area of rainfed crops, basically olive trees, cereals and vineyards. Practically circular, it lacks a perilagunar belt, although its underwater vegetation is very important. With a surface of 5.46 Hectares of Natural Reserve and 116 of protection, it has a maximum depth of 0.4 m. It houses a large number of ducks and shorebirds during the winter. It is usually used as a resting place by bands of real Ducks. Laguna Dulce (Freshwater Lagoon). The Laguna Dulce was dried for 25 years for the cultivation of cereal, and today it has been acquired by the administration and restored with the intention of obtaining in it the most natural state possible. With this purpose, the drainages were eliminated and the banks were repopulated. It is curious the spatial distribution of this lagoon and its neighbour Laguna Amarga (Bitter Lagoon). Being located less than 50 m the one of the other, the physical-chemical characteristics of their waters are very different, as their own name indicates. One has bitter waters and the other sweet waters. One is seasonal and the other permanent. All this means that there are different species in each of them, increasing the diversity of the whole and complementing both. Malpasillo Reservoir. Reservoir located in the south of the Cordobilla, on the Genil river, in a steep relief, sits on soil formed by gypsiferous marls. In the riparian vegetation it is necessary to point out the abundance of reeds and bulrushes. Malpasillo is the ideal habitat for the purple gallinule and the scarce ruddy duck has also been counted in it. Among the most abundant waterfowl, there is the Mallard, the red duck and the Anas clypeata. Like the Cordobilla, the Natural Site of the Malpasillo Reservoir is located in the south of the province of Córdoba and north-eastern part of Seville. Its extension is 512 hectares. Cordobilla Reservoir built on the Genil, is the last of a series of three that this river possesses before flowing into the Guadalquivir. It is surrounded by agricultural lands that settle in a soft and open relief and its banks are covered with abundant vegetation. On these shores, in addition to tamarisk and willows, the most characteristic marshy vegetation is formed by bulrushes, cattails and reeds, while its banks serve as a refuge for abundant aquatic fauna. In the reservoir it is frequent to see the grey heron, the imperial heron and the common stork. The purple gallinule is a sedentary species in this swamp. In the vicinity of Cordobilla, a southern town of Córdoba, which serves as a reference to the reservoir, the presence of the crane has been detected. The surface of this Natural Site, between the provinces of Córdoba and Seville, is 1400 hectares.
