[00:00.00]The bird recordings and recreated songs you hear now
[00:03.82]are all of species that have disappeared
[00:06.58]from these main-island forests.
[00:08.69]we can't just blame Tibbles and his kin.
[00:11.72]Humans have brought a whole range of mammalian competitors
[00:15.55]and predators to these shores.
[00:17.75]Today, the people of New Zealand are making amends.
[00:21.38]This is New Zealand's most famous tree - Tane Mahuta,
[00:26.50]Lord of the Forest. “
[00:27.80]There's more wood in this kauri tree
[00:29.69]than in any other tropical tree in the world.
[00:32.81]conservationists are working hard to protect
[00:35.35]and nurture these special forests.
[00:37.57]By collecting kauri seeds,
[00:39.23]they ensure that new trees can be cultivated
[00:42.05]and the forest expanded into its former range.
[00:45.42]Meanwhile, the animal invaders are being controlled,
[00:48.92]and birds that only survived on small outlying islands
[00:52.32]are now being reintroduced to these mighty forests.
[00:55.99]Back in Hawaii, being the remotest of all archipelagos,
[01:00.77]you might expect the unique wildlife to have fared rather better.
