The bird recordings and recreated songs you hear now

Are all of species that have disappeared

From these main-island forests

We can't just blame Tibbles and his kin

Humans have brought a whole range of mammalian competitors

And predators to these shores

Today the people of New Zealand are making amends

This is New Zealand's most famous tree

Tane Mahuta

Lord of the Forest

There's more wood in this kauri tree

Than in any other tropical tree in the world

Conservationists are working hard to protect

And nurture these special forests

By collecting kauri seeds

They ensure that new trees can be cultivated

And the forest expanded into its former range

Meanwhile the animal invaders are being controlled

And birds that only survived on small outlying islands

Are now being reintroduced to these mighty forests

Back in Hawaii being the remotest of all archipelagos

You might expect the unique wildlife to have fared rather better
