The Sub-Antarctic Islands are in the Southern Ocean and lie southeast of Tasmania and south of the southern island of New Zealand. They are all World Heritage Sites for several reasons, amongst which are:
They are home to over half of the world’s seabirds, some of whom exist nowhere else; They show easily seen geologic evidence of both volcanic activity and glaciation; They have plant species which are giants compared to their relatives in more temperate climates; They have been the subjects of ecological restoration efforts which have been, in some cases, highly successful.
