Rangatauanui
Rangatauanui is a maar lake south of Ohakune in the North Island of New Zealand. It is in the area of the southernmost volcanic activity in the Taupō Rift. Its undisturbed lake sediments have proved useful in reconstructing recent climate proxy records for New Zealand. Geography It is south of Ohakune in the Ngā Roto-o-Rangataua Scenic Reserve, which before 2019 was known as the Ohakune Lakes Scenic Reserve. This has an area of about the about . Historically it has been called Rangataua Crater Lake. Adjacent is another smaller maar lake, Rangatauaiti, in the area that has been called the Rangataua craters in the geological literature. Geology Along with Rangatauaiti it is a maar lake, believed to have been formed about 30,000 years ago. The nearest other volcanoes are to the north, being the Ohakune volcanic complex and it is unclear if the maar lakes are similar potential Ruapehu parasites, representing the southernmost vents of the Taupō Volcanic Zone which is defined ...

Ohakune Volcanic Complex
The Ohakune volcanic complex (Ohakune craters, Rochfort Crater) is a small extinct monogenetic volcano south-west of Mount Ruapehu and just north of the town of Ohakune in Manawatū-Whanganui, New Zealand. It is in the area of the southernmost volcanic activity in the Taupō Rift and located adjacent to the potentially active Ohakune Fault. Geography The complex is located at the north-western corner of the town of Ohakune at the Tongariro National Park boundary and bisected by the main trunk railway line as it leaves the town to the north-west. Although the Ohakune volcanic complex is also known as the Rochfort Crater, this is the geographical name for the largest of several craters associated with the complex. South of the main trunk railway line is the main scoria cone that reaches a height of and has been quarried on its south-eastern flank. There are a couple of depressions south of the railway line adjacent to the town. North of the line the volcano is mainly fores ...

Ohakune
Ohakune is a small town at the southern end of Tongariro National Park, close to the southwestern slopes of the active volcano Mount Ruapehu, in the North Island of New Zealand. A rural service town known as New Zealand's Carrot Capital, Ohakune is a popular base in winter for skiers using the ski resorts, ski fields (particularly Turoa) of Mount Ruapehu and in summer for Tramping in New Zealand, trampers hiking the Tongariro Alpine Crossing. Toponymy The Ngāti Rangi iwi say the Māori language name ''Ohakune'' comes from the phrase "''he Ohakune ki te ao''", which broadly means "an opening to a new world" and refers to the descent from Mount Ruapehu into the valley and swamps of the area. In 2019 the New Zealand Geographic Board changed the official name to ''Ōhakune'', indicating that the first letter was a long vowel, but swiftly reverted to ''Ohakune'' without a macron when Ngāti Rangi objected.

Leptospermum Scoparium
''Leptospermum'' is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of '' Melaleuca''. Most species are endemic to Australia, with the greatest diversity in the south of the continent, but some are native to other parts of the world, including New Zealand and Southeast Asia. Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals. There is a single style in the centre of the flower and the fruit is a woody capsule. The first formal description of a leptospermum was published in 1776 by the German botanists Johann Reinhold Forster and his son Johann Georg Adam Forster, but an unambiguous definition of individual species in the genus was not achieved until 1979. Leptospermums grow in a wide range of habitats but are most commonly found in moist, low-nutrient soils. They have important uses in horticulture, in the produc ...

Volcanoes Of Manawatū-Whanganui
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology."

Tongariro Volcanic Centre
The North Island Volcanic Plateau (often called the Central Plateau and occasionally the Waimarino Plateau) is a volcanic plateau covering much of central North Island of New Zealand with volcanoes, lava plateaus, and crater lakes. It contains the Taupō caldera complex, Ōkataina caldera complex and Tongariro Volcanic Centre resulting in it being currently the most frequently active and productive area of silicic volcanism on Earth. New Zealand is part of the Pacific Ring of Fire. Location and description The plateau is approximately east–west and the north–south distance is about . Extensive ignimbrite sheets spread east and west from the Central Taupō Volcanic Zone, centred on the huge active supervolcanic caldera of Lake Taupō, now the largest lake in New Zealand. This last erupted less than 2000 years ago. The volcanic area includes the three active peaks of Mount Tongariro, Mount Ngauruhoe, and Mount Ruapehu in the south, and extends beyond Rotorua in the n ...

Metrosideros Robusta
''Metrosideros robusta'', commonly known as the northern rātā, is a forest tree endemic to New Zealand. It grows up to or taller, and usually begins its life as a hemiepiphyte high in the branches of a mature forest tree; over centuries the young tree sends descending and girdling roots down and around the trunk of its host, eventually forming a massive, frequently hollow pseudotrunk composed of fused roots. In disturbed ground, or where there are gaps in the forest cover, northern rātā will grow on the ground with a normal but short trunk. Distribution Northern rātā is found in the North Island from Te Paki in the north to Wellington in the south. Formerly widespread, it is now uncommon over large parts of its former range, and is apparently absent from all but the south-east of Hawke's Bay. In the South Island, northern rātā is common from Nelson to Greymouth and Hokitika. It reaches its southern limit near Lake Mahinapua at 42°4′ South latitude. The natural ...

Epiphyte
An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. In some cases, a rainforest tree's epiphytes may total "several tonnes" (several long tons). They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knightia Excelsa
''Knightia excelsa'', commonly known as rewarewa (from Māori), is an evergreen tree endemic to the low elevation and valley forests of New Zealand. It is found in the North Island and at the tip of the South Island in the Marlborough Sounds (41° S) and the type species for the genus '' Knightia''. Rewarewa grows to tall, with a slender crown. The leaves are alternate, leathery, narrow oblong, 10 – 15 cm long and 2.5 – 3.5 cm wide, and without stipules. The flowers are 2 – 3.5 cm long, bright red, and borne in racemes 10 cm long. Produces dry woody follicles. It was called New Zealand honeysuckle by early European settlers but the name has fallen into disuse in preference for the Māori name. Rewarewa flowers are a great source for honey production. The rewarewa is known for its timber, which is handsomely figured for interior work although not durable in exposed situations.

Pterophylla Racemosa
''Pterophylla racemosa'', commonly known as the kāmahi, is an evergreen tree endemic to New Zealand. It is a member of the Cunoniaceae family of plants, and it is often referred to by its former botanical name ''Weinmannia racemosa.'' Most members of the Cunoniaceae are native to tropical wet parts of the Southern Hemisphere, with the majority of ''Pterophylla'' species being native to either Malesia and Papuasia or to Madagascar; however, two ''Pterophylla'' species are endemic to New Zealand: ''Pterophylla racemosa'', and '' Pterophylla sylvicola''.'''' Whilst ''P. sylvicola'' is restricted to subtropical forests in the far north of North Island, ''P. racemosa'' is found growing across vast areas of the country as far south as Stewart Island and is found in a variety of climatic conditions from mild coastal areas to mountainous (sub)-alpine areas inland. The abundance of the kāmahi (''P. racemosa'') across New Zealand has led to it long being described as the common tree i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dacrycarpus Dacrydioides
''Dacrycarpus dacrydioides'', commonly known as kahikatea (from Māori) and white pine, is a coniferous tree endemic to New Zealand. A podocarp, it is New Zealand's tallest tree, gaining heights of over a life span of 600 years. It was first described botanically by the French botanist Achille Richard in 1832 as ''Podocarpus'' ''dacrydioides'', and was given its current binomial name ''Dacrycarpus dacrydioides'' in 1969 by the American botanist David de Laubenfels. Analysis of DNA has confirmed its evolutionary relationship with other species in the genera ''Dacrycarpus'' and ''Dacrydium''. In Māori culture, it is an important source of timber for the building of waka and making of tools, of food in the form of its berries, and of dye. Its use for timber and its damp fertile habitat, ideal for dairy farming, have led to its decimation almost everywhere except South Westland. Kahikatea seeds have fleshy structures called receptacles attached to them, which encourage bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
