Los humedales Ramsar en España: reflexiones a propósito de su trigésimo aniversario

The paper is about the Spanish wetlands included in the Ramsar Convention. An introduction is made outlining its main territorial features; after comes a characterization, discussed from different points of view, such as geographical location, natural degree, physical structure and genesis, among others aspects for which specialized literature has been of great advice. This approach detects different problems to face, such as those related to access and water quality, terrain degradation or degradation associated with its use and management. Finally a brief systematization of contents is made, focusing on the inconsistency of Ramsar's Spanish network. An intentionally brief account of wetlands to consider is added.
