The Columbretes Islands are located 30 [nautical] miles off the coast of Catello. This is a small archipelago, composed of [four] groups of islets, L'Illa Grossa, La Foradada, La Ferrera and El Carallot.
The Columbretes islands are of volcanic origin. .They rise over the continental platform from the sea bottom 80-90 m depth in the form of submerged reefs and emerged islands. This volcanic field is considered as one of hte scarce examples of Quaternary vulcanism in the continental shelf of the Mediterranean.
The sea around Columbretes islands is quite rocky with caves and volcanic structures. The submerged reefs cover 5.0 ha, with platforms, pithons and underwater caves.
Specificities and Importance
Mediterranean infralitoral and circalitoral communities are well respresented and preserved in the Columbretes Island Marine reserve. Cymodocea nodosa meadows occur around parts of La Ferrera, La Foradad and El Carallot islets. Hard substratum communities, ranging from photophylic algal communities to coralligenous assemblages, are present around the four main islets groups, as well as in rocky submerged banks. Maerl beds cover most of the deep subtrata in the Columbretes archipelago.
