Lord Howe Island

____________________________________________________________________________

Two-thirds of the Lord Howe Island group, declared a World Heritage Area in 1982, is a Permanent Park Preserve. Lord Howe Island itself, 11 km long by 6 km wide, is all that remains of an extinct shield volcano that arose about 7 mya and erupted for half a million years, now eroded to a fortieth of its original size. The island’s vegetation represents insular development and evolution of Gondwanan elements borne by sea, wind and bird; 129 of the island’s plant genera are shared with Australia, 102 with New Caledonia and 75 with New Zealand.
