 There used to be a large short-tailed shearwater colony on the western side of the island until the early 20th century, when it was destroyed though the introduction of pigs, which dug up the burrows and ate the eggs and chicks.The metallic skink is present.In 2017 it was proposed that houses were built on Anderson Island, due to the conservation status though this never occurred as it would likely damage the sooty oystercatcher colony.
