Macauley Island


Macauley Island is a volcanic island in New Zealand's Kermadec Islands, approximately halfway between New Zealand's North Island and Tonga in the southwest Pacific Ocean. Its co-ordinates are

Geography

Macauley Island is the second-largest of the Kermadec islands (after Raoul Island), and covers an area of 3.06 km2 (1.181 sq mi), including neighbouring Haszard Island, which is 220 m (722 ft) to the east and about 5 ha (12 acres) in area. The island's topography is simple, being a single high-sided plateau, with the soft rock of the island prone to the formation of deep water channels.[1] Macauley's highest point is 238 m (781 ft) Mount Haszard, and it forms part of the rim of a caldera centred 8 km (5 mi) to the north-west, atop a large submarine volcano. The volcano's last eruption was in 4360 BC ± 200 years.

History

Lieutenant William Curtis part owner of The Lady Penrhyn along with his brother Timothy — on the Lady Penrhyn in the late 1788.[2] Lady Penrhyn had delivered convicts to New South Wales as part of the First Fleet and was proceeding to the north west coast of America refer[3] to trade furs and thence to Macao.

A castaway depot was established on Macauley Island in 1889, which was regularly serviced until 1918.[1]

Flora and fauna

The island is a breeding site for large numbers of black-winged and white-necked petrels. Other seabirds recorded as breeding there include grey noddies, sooty terns, masked boobies, red-tailed tropicbirds, wedge-tailed shearwaters, Kermadec little shearwaters, Kermadec petrels and Kermadec storm-petrels. The island also holds a population of the Kermadec red-crowned parakeet. Former populations of goats and kiore have been eradicated.[4] The island forms part of the Kermadec Islands Important Bird Area, identified as such by BirdLife International because it is an important site for nesting seabirds.[5]

The island’s flora is predominantly sedges and ferns, with Cyperus and Hypolepis prominent.[1]

Conservation

The original forest cover of the island had been burnt off and goats were introduced as food for shipwreck survivors. The goats were eradicated by the New Zealand Wildlife Service in the late 1960s and early 1970s. In order to protect the island's wildlife, Macauley is managed as a nature reserve by the New Zealand Department of Conservation (DOC). In 2006, DOC used aerial drops of poison bait in order to remove introduced rats.
