http://www.oxleytravel.com.au/lhi/ Being placed on the world heritage list stopped foreign animals like cats, pigs, goats and rats from being introduced and ruining the island’s biodiversity. UNESCO also limited the number of tourist beds to 400 so it will not damage the environment. After rats were accidentally introduced, 5 species of endemic birds were extinct within two years. So UNESCO eradicated all foreign plants and animals from Lord Howe Island. The island is now back to normal and undisturbed beauty.
