Dent Island, New Zealand
Dent Island is a subantarctic rock stack, lying 3 km west of Campbell Island and belonging to the Campbell Island group. Dent Island is located at . It was named by the French 1874 Transit of Venus Expedition to Campbell Island because of its resemblance to a tooth (''dent'' in French). Birds The island is part of the Campbell Island group Important Bird Area (IBA), identified as such by BirdLife International because of its significance as a breeding site for several species of seabirds as well as the endemic Campbell teal and Campbell snipe. Campbell teal The island is most famous for its Campbell teal, which was thought to have been extinct for more than 100 years until a small group was rediscovered there in 1975. Dent Island is free from predators, especially the rats whose introduction on Campbell Island led to the extinction of the teal there. However, the suitable habitat for the teal on Dent Island is much more limited than its area would suggest, because a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campbell Island Group
The Campbell Islands (or Campbell Island Group) are a group of subantarctic islands, belonging to New Zealand. They lie about 600 km south of Stewart Island. The islands have a total area of , consisting of one big island, Campbell Island (), and several small islets, notably Dent Island (), Isle de Jeanette Marie (), Folly Island (or Folly Islands), Jacquemart Island (), and Monowai Island (also known as Lion Rock, ). Ecologically, they are part of the Antipodes Subantarctic Islands tundra ecoregion. The islands are one of five subantarctic island groups collectively designated as a World Heritage Site by UNESCO. Geography * Campbell Island / Motu Ihupuku () * Dent Island () * Jacquemart Island () * Folly Island or Folly Islands The islands are relatively flat; due to tectonic pressure, however, there are mountains in the centre of each island. A sea stack at the southern tip of Jacquemart Island is – with the exception of the country's Antarctic claims – New Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campbell Teal
The Campbell teal or Campbell Island teal (''Anas nesiotis'') is a small, flightless, nocturnal species of dabbling duck of the genus ''Anas'' endemic to the Campbell Island group of New Zealand. It is sometimes considered conspecific with the brown teal. The plumage is similar to that of the Auckland teal, dark sepia with the head and back tinged with green iridescence, and a chestnut breast on the male, with the female dark brown all over. Its natural habitat is tussock grassland dominated by '' Poa'' tussock grass, ferns and megaherbs. The species also uses the burrows and pathways of petrel species that nest on the islands. They are apparently territorial in the wild, and probably feed on amphipods and insects. The IUCN classifies it as vulnerable. Conservation left The Campbell teal was once found on Campbell Island, but was driven to extinction there by the introduction of Norway Rats (which ate their eggs and chicks), and was for a while presumed extinct. In 1975 it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islands Of The Campbell Islands
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megaherb
Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands. They suffer from overgrazing due to introduced mammals. Appearance and occurrence Originally, the term was coined to describe large-leaved herbs that form meadows in the subantarctic islands but has also been applied to describe tropical alpine vegetation forms found in the Andes, East Africa and New Guinea. They are large herbs that can reach dimensions of over one metre, often feature strikingly colourful flowers, large leaves and long stalks, and are important components of the ecosystems of the subantarctic islands. Beyond these traits, megaherbs can have different forms; for example, some genera have perennial leaves and others are deciduous. Int ...

New Zealand Subantarctic Islands
The New Zealand Subantarctic Islands comprise the five southernmost groups of the New Zealand outlying islands. They are collectively designated as a UNESCO World Heritage Site. Most of the islands lie near the southeast edge of the largely submerged continent centred on New Zealand called Zealandia, which was riven from Australia 60–85 million years ago, and from Antarctica 85–130 million years ago. They share some features with Australia's Macquarie Island to the west. History Until 1995, scientific research staff were stationed permanently at a meteorological station on Campbell Island. Since then, the islands have been uninhabited, though they are periodically visited by researchers and tourists. Protection of reserves was strengthened in 2014, becoming the largest natural sanctuary in the nation.

Pukaha / Mount Bruce National Wildlife Centre
Pūkaha / Mount Bruce National Wildlife Centre is a captive breeding facility and visitor centre located in a protected forest area on State Highway 2 in New Zealand's Tararua district. Location Pukaha / Mount Bruce National Wildlife Centre is located on State Highway 2, 30km north of Masterton and 10km south of Eketahuna. It is within a 'government purpose' wildlife management reserve that is approximately 57.3ha in area. The National Wildlife Centre Reserve is enclosed on three sides by the larger Pukaha / Mount Bruce scenic reserve of 891ha. These reserves are protected areas under the Reserves Act 1977. History The forest was acquired by the government in the 1870s as part of Seventy Mile Bush, which covered the area from Masterton to Central Hawkes Bay before European settlement. Most of the bush was destroyed and converted to farmland, but the 942 hectare Mount Bruce block was protected as a Forest Reserve. Some 55 ha of this was further protected as a Native Bird Reser ...

Campbell Snipe
The Campbell snipe (''Coenocorypha aucklandica perseverance''), also known as the Campbell Island snipe, is a rare subspecies of the Subantarctic snipe, endemic to Campbell Island, a subantarctic island south of New Zealand in the Southern Ocean. It was not formally described until January 2010.Miskelly & Baker (2010a, b). The subspecific name alludes to the name of the sealing brig ''Perseverance'', captained by Frederick Hasselborough, that discovered Campbell Island in 1810, and which probably inadvertently introduced rats to the island when it was wrecked there in 1828.DOC media release (2010). History The existence of the Campbell snipe was unknown until 1997 when, during a search for the Campbell teal, there was the chance discovery of a small population on an almost inaccessible rock, Jacquemart Island. Thus there is not much information about it and it remains one of the least known birds in the world.Miskelly & Fraser (2006). Austral snipe are extinct on the mainla ...

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.
