Henderson Island

Henderson Island is an uninhabited island in the south Pacific Ocean. With Pitcairn, Oeno and Ducie Islands it forms the Pitcairn Island Group.

It is one of the world's last two raised coral atolls whose ecosystems remain relatively unaffected by human contact, though a 2017 survey found a large amount of plastic debris accumulating on its beaches. 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.Measuring 9.6 kilometres by 5.1 kilometres, it has an area of 37.3 square kilometres and is located 193 kilometres northeast of Pitcairn Island. It has poor soil and little fresh water, and is unsuitable for agriculture. There are three beaches on the northern end and the remaining coast comprises steep cliffs up to 15 metres in height.
