Thanks to the variety of soil types in the area, the wetlands in the south of the province of Córdoba provide a uniquely suitable habitat for a large number of bird and plant species.

The Nature Reserve includes permanent lakes, such as Zóñar, Rincón and Amarga and also seasonal ones like Tíscar, Los Jarales and El Salobral. They have all been declared protected areas because of their importance as winter migration and nesting areas for waterfowl.

These oases surrounded by bulrushes and reeds contrast sharply with the fertile campiña landscape of Córdoba olive groves, vineyards and cereal fields.

Here there are also glasswort and sea heath.
