[00:00.00]In the lowlands,
[00:01.08]there are lush coastal rainforests teeming with life.
[00:05.40]But not indigenous life.
[00:08.90]None of the plants or animals you see here is actually native.
[00:13.75]Jackson's chameleons were brought from East Africa as exotic pets.
[00:19.13]The white-rumped shama from India
[00:21.50]and the northern cardinal from North America
[00:24.39]were both introduced to supplement the native bird life,
[00:28.11]while the red-billed leiothrix was a cage bird imported from China.
[00:33.98]And the Japanese white-eye was imported in an attempt
[00:37.46]to control insect pests.
[00:39.53]Before humans,
[00:40.56]only one new species reached Hawaii every 35,000 years.
[00:45.10]Now up to 50 new species turn up every year.
[00:49.45]Invaders are everywhere,
[00:52.23]and some have had a significant impact.
[00:55.09]In an attempt to control introduced rats,
[00:59.31]humans brought the Indian mongoose to Hawaii.
[01:02.34]Unfortunately,
[01:03.55]no one considered the fact that rats are nocturnal,
[01:06.35]while the mongoose hunts by day,
[01:08.45]so the hungry mongoose turned its attention
[01:10.45]to decimating the island's unique bird life instead.
