Environment of New Zealand

The environment of New Zealand is characterised by unique flora and fauna and a variety of landforms contained within a small island nation. The biota of New Zealand is one of the most unusual on Earth, due to its long isolation from other continental landmasses. Its affinities are derived in part from Gondwana, from which it separated 82 million years ago, some modest affinities with New Caledonia and Lord Howe Island, both of which are part of ... more

The environment of New Zealand is characterised by unique flora and fauna and a variety of landforms contained within a small island nation. The biota of New Zealand is one of the most unusual on Earth, due to its long isolation from other continental landmasses. Its affinities are derived in part from Gondwana, from which it separated 82 million years ago, some modest affinities with New Caledonia and Lord Howe Island, both of which are part of the same continental plate as New Zealand and in part from Australia. More recently a component has been introduced by humans. New Zealand's biodiversity exhibits high levels of endemism, both in its flora and fauna. Until recently the islands had no native terrestrial mammals except for bats (although mammals did exist in New Zealand until 19 million years ago), the main component of the fauna being insects and birds. Its flora is dominated by Gondwanan plants, comprising historically of forests, most famously the giant kauri. New Zealand has... less
