Henderson Island (Pitcairn Islands)

Henderson Island (formerly also San Juan Bautista and Elizabeth Island) is an uninhabited island in the south Pacific Ocean. It is one of the world's last two raised coral atolls whose ecosystems remain relatively unaffected by human contact. Ten of its 51 flowering plants, all four of its land birds and about a third of the identified insects and gastropods are endemic – a remarkable diversity given the island's size.
