Pleurophyllum Criniferum
''Pleurophyllum criniferum'' is a species of flowering plant in the family Asteraceae that is endemic to the subantarctic islands of New Zealand. Description ''Pleurophyllum criniferum'' is a large perennial herb, growing up to 2 m in height. The leaves may grow to a metre or more in length and are diverse in shape, though usually oblong-ovate to lanceolate, the undersides covered by silky white hairs. The flowers occur as 15–30 heads in elongated racemes with short and inconspicuous ray-florets and dark purple disk-florets. The plant flowers from December to February and fruits from January to May. Distribution and habitat The plant is endemic to New Zealand’s subantarctic Antipodes, Auckland and Campbell Islands, where it is a striking component of the megaherb community. It occurs from the coast up into the island ranges on peaty ground in herbfield Herbfields are plant communities dominated by herbaceous plants, especially forbs and grasses. They are found whe ...

Campbell Island, New Zealand
Campbell Island / Motu Ihupuku is an uninhabited subantarctic island of New Zealand, and the main island of the Campbell Island group. It covers of the group's , and is surrounded by numerous stacks, rocks and islets like Dent Island, Folly Island (or Folly Islands), Isle de Jeanette-Marie, and Jacquemart Island, the latter being the southernmost extremity of New Zealand. The island is mountainous, rising to over in the south. A long fiord, Perseverance Harbour, nearly bisects it, opening out to sea on the east coast. The island is listed with the New Zealand Outlying Islands. The island is an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all other outlying islands, other than the Solander Islands. It is the closest piece of land to the antipodal point of the United Kingdom, and Ireland, meaning that the furthest away city is Limerick, Ireland. Campbell Island is a UNESCO World Heritage Site. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of The Auckland Islands
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herbfield
Herbfields are plant communities dominated by herbaceous plants, especially forbs and grasses. They are found where climatic conditions do not allow large woody plants to grow, such as in subantarctic and alpine tundra environments. Herbfield is defined in New South Wales (Australia) government legislation as native vegetation that predominantly does not contain an over-storey or a mid-storey and where ground cover is dominated by non-grass species. The New Zealand Department of Conservation The Department of Conservation (DOC; Māori: ''Te Papa Atawhai'') is the public service department of New Zealand charged with the conservation of New Zealand's natural and historical heritage. An advisory body, the New Zealand Conservation Au ... has described herbfield vegetation as that in which the cover of herbs in the canopy is 20–100%, and in which herb cover is greater than that of any other growth form, or of bare ground.Lux et al. (2009). Various kinds of herbfield include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...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 ...

Auckland Islands
The Auckland Islands (Māori: ''Motu Maha'' "Many islands" or ''Maungahuka'' "Snowy mountains") are an archipelago of New Zealand, lying south of the South Island. The main Auckland Island, occupying , is surrounded by smaller Adams Island, Enderby Island, Disappointment Island, Ewing Island, Rose Island, Dundas Island, and Green Island, with a combined area of . The islands have no permanent human inhabitants. The islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all the other outlying islands except the Solander Islands. Ecologically, the Auckland Islands form part of the Antipodes Subantarctic Islands tundra ecoregion. Along with other New Zealand Sub-Antarctic Islands, they were designated a UNESCO World Heritage Site in 1998. Geography The Auckland Islands lie south of Stewart Island, and from the South Islan ...

Antipodes Islands
The Antipodes Islands ( Maōri: Moutere Mahue; "Abandoned island") are inhospitable and uninhabited volcanic islands in subantarctic waters to the south of – and territorially part of – New Zealand. The 21 km2 archipelago lies 860 km to the southeast of Stewart Island/Rakiura, and 730 km to the northeast of Campbell Island. They are very close to being the antipodal point to Normandy in France, meaning that the city farthest away is Cherbourg-en-Cotentin, France. The island group consists of one main island, Antipodes Island, of 20 km2 area, Bollons Island to the north, and numerous small islets and stacks. The islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all the other outlying islands except the Solander Islands.

Subantarctic
The sub-Antarctic zone is a region in the Southern Hemisphere, located immediately north of the Antarctic region. This translates roughly to a latitude of between 46° and 60° south of the Equator. The subantarctic region includes many islands in the southern parts of the Atlantic, Indian, and Pacific oceans, especially those situated north of the Antarctic Convergence. Sub-Antarctic glaciers are, by definition, located on islands within the sub-Antarctic region. All glaciers located on the continent of Antarctica are by definition considered to be Antarctic glaciers. Geography The sub-Antarctic region comprises two geographic zones and three distinct fronts. The northernmost boundary of the subantarctic region is the rather ill-defined Subtropical Front (STF), also referred to as the Subtropical Convergence. To the south of the STF is a geographic zone, the Subantarctic Zone (SAZ). South of the SAZ is the Subantarctic Front (SAF). South of the SAF is another marine zone, cal ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
