Valencian CommunityProvince Castelló Comarca Plana Alta Judicial district Castelló de la Plana Area - Total 0.19 km2 (0.1 sq mi) Highest elevation 67 m (220 ft) Population (2009) - Total no permanent population Time zone CET (UTC+1) - Summer (DST) CEST (UTC+2) Postal code 12100 The Columbretes Islands (Valencian: Els Columbrets, IPA: [eɫs kolumˈbɾets]) are a group of small uninhabited islets of volcanic origin, in the Mediterranean Sea, 49 km off Oropesa del Mar. Administratively they belong to Castelló de la Plana municipality, Valencian Community, Spain.
The main islets are Illa Grossa (Spanish: Columbrete Grande), La Ferrera, La Foradada and El Carallot. The total emerged area of all four is around 0.19 km² and the highest point is 67 m. Illa Grossa, by far the largest, is the northernmost island of the group. It stands in the place of an ancient crater and shows a distinctive semi-circular pattern. There are no buildings on it, except for a 19th century lighthouse, a jetty and the staff quarters used by the biologists working in the wildlife reserve.

History
These islands were known by Greeks and Romans from ancient times. Writers such as Strabo or Pliny the Elder cited the astonishing amount of snakes inhabiting them. The names Ophiusa and Colubraria by which they were named (meaning serpent in Greek and Latin, respectively) refer to that fact. The islands owe their present name to "Colubraria", the Latin word for "snake".
After a lighthouse was built on Illa Grossa in mid-19th century, a few people were settled on it. The small community looked after maintenance of the lighthouse and helped to deter smugglers who used the islets as a refuge. Farm animals including pigs were introduced. This, combined with aggressive practices such as the burning of the original bushy vegetation of the lighthouse island (partly for agricultural uses and also to deliberately deprive the numerous endemic snub-nosed vipers of their natural habitat), caused the snakes to become extinct by the end of the 19th century. The only testimony of their past abundance that remains today is a stuffed viper from the Columbretes in Madrid's Natural Science Museum.[1]
Biosphere reserve
Since 1988 the archipelago has been declared a wildlife reserve. It is as an optimal place for the reproductive activities of certain sea birds. The local colony of Audouin's Gulls (which is a species listed as Near Threatened globally) is one of the most important in the world and key to the species ongoing recovery in the Spanish Mediterranean. The islets are also home for one of the major stable populations of Eleanora's Falcon in Spain. Besides, the islets are very important during spring and autumn bird migrations, since many different species who follow the Spanish Mediterranean coast in the course of their migration use them as a brief stop in order to rest.
Due to its isolation, the islands are inhabited by an endemic subspecies of small lizard, Podarcis hispanica atrata.[2] There is also an endemic subspecies of Lobularia maritima in the local flora.[3] After being given the Natural Park status, pigs were eradicated. Also, the lighthouse is now automatic, which reduces the human presence only to the one of biologists assigned to the park's management.
The submerged area around the islands is as relevant in terms of conservation as the area above the surface. It covers an area of 400 km² where an important community of submarine wildlife thrives undisturbed. It became protected as a Marine reserve in 1990.
