is the name of one of the islets
surrounding Campbell Island, New Zealand
. It is located 1 km south of Campbell Island at and is the southernmost island
of New Zealand
. The exact coordinates of this extreme point are . While Jacquemart Island still belongs indisputably to New Zealand, New Zealand also claims territory in Antarctica
which stretches to the South Pole
. Like other Antarctic territorial claims, New Zealand's jurisdiction over the Ross Dependency
is not recognised by most nations.The name 'Jaquemart' originates from the name of the Captain of the vessel of the French Expedition to Campbell Island in 1874.
Jacquemart Island is a stack
with an area of 19 ha
, being about 750 m in length by 500 m in width and surrounded by precipitous cliffs at least 30 m high at their lowest. Its highest point is about 200 m asl
. It is an eroded remnant of basaltic lavas
originally laid down on a sedimentary base. Because of its inacessibility from the sea, the first visit by humans to the island did not take place until 29 December 1980 when a small party of scientists was landed by helicopter on the summit ridge for a 90 minute survey. Subsequent short visits were made in 1984 and 1997.
Flora and fauna
Much of the area of the island above the cliffs is covered with tussock grassland
on a substratum of peat
undermined with petrel burrows. There are also herbfield communities, rock and ledge communities, as well as lichens
and cushion plants
Birds recorded as breeding on Jacquemart include Sooty Shearwater, Northern Giant Petrel, Grey-backed Storm-petrel, Light-mantled Sooty Albatross, Brown Skua and Campbell Island Shag. Other seabirds which may breed there are Common Diving-petrel and Cape Petrel. Australasian Pipits and Common Starlings have been seen. A species of cave weta has also been recorded from the island, as well as the Campbell Island Leaf-veined Slug.
Campbell Island Snipe
Until the Campbell Islands were cleared of introduced rats
in 2001, Jacquemart was also the last refuge of the Campbell Island Snipe
, an undescribed race or species of New Zealand snipe
only discovered in 1997. After the eradication
of rats the snipe began to recolonise the rest of the group, with a small breeding population discovered in 2005 on southern Campbell Island opposite Jacquemart.
