Desecheo Island

Desecheo es una isla deshabitada de 360 acres (370.7 cuerdas) aproximadamente a 14 millas al oeste de Puerto Rico.  Originalmente descubierta por Cristóbal Colón en su segundo viaje a las Américas, la isla fue nombrada más tarde por el explorador Núñez Álvarez de Aragón en 1517.  En el siglo XVIII, contrabandistas y piratas usaban la isla para, entre otras cosas, cazar cabras salvajes.  A principios de 1900, la isla tenía la colonia de piqueros pardos (un ave marina) más grande del mundo, lo que llevó al Presidente Taft, en 1912, a designarla como reserva.  Durante la Segunda Guerra Mundial, los militares adquirieron la isla y, entre 1940 y 1964, la utilizaron para actividades de entrenamiento, incluso como campo de tiro y bombardeo.  En 1964, los militares transfirieron la propiedad al Instituto Nacional de Salud, quien lo utilizó para experimentos científicos.  En 1976, Desecheo fue transferido al Servicio Federal de Pesca y Vida Silvestre, y desde 1983 la agencia lo ha administrado como un Refugio Nacional de Vida Silvestre.  Aún cuando el buceo recreacional es frecuente en las aguas alrededor de la isla, la isla está cerrada al público.

Desecheo is a 360-acre (370.7 cuerdas) uninhabited island approximately 14 miles west of mainland Puerto Rico.  Originally discovered by Christopher Columbus on his second trip to the Americas, the island was later named by explorer Nuñez Alvarez de Aragón in 1517.  In the 18th century, smugglers and pirates used the island for, among other things, hunting wild goats.  In the early 1900’s the island had the world’s largest brown booby (a seabird) colony in the world, leading President Taft, in 1912, to designate it as a preserve.  During World War II, the military acquired the island, and, between 1940 and 1964, they used it for training activities including as a bombing and gunnery range.  In 1964, the military transferred ownership to the National Institute of Health who used it for scientific experiments.  In 1976, Desecheo was transferred to the U.S. Fish and Wildlife Service, and since 1983 the agency has managed it as a National Wildlife Refuge.  While recreational divers frequent the waters around the island, it is closed to the public.
