Gough and Inaccessible Islands

Seabirds in vast colonies wheel around the sheer cliffs of Gough and Inaccessible, two remote islands of the Tristan da Cunha group in the South Atlantic that rank among the least disturbed cool-temperate ecosystems on the planet. Gough counts two endemic land birds and a dozen endemic plants; Inaccessible earns its name and adds still more species found nowhere else, including the world's smallest flightless bird, the Inaccessible Island rail. UNESCO inscribed the site in 1995.
