Natural regions of Western Andalusia

This work is a digital map that delimits the 16 natural regions in which western Andalusia has been divided, integrated by the provinces of Huelva, Cadiz, Seville and Cordoba. These regions are: Pedroches, Zújar, Sierra Norte, Aracena, Andévalo, Campiña de Huelva, Condado-Aljarafe, Vega, Alcores, Litoral, Marisma, Campiña Baja, Campiña Alta, Subbetica, Grazalema and Algeciras. This historical layer is based on the publication “Flora Vascular de Andalucía Occidental” (1987, Ed. Ketres). The limits have not recently been revised, although it seems to be the only layer of this existing theme.
