Environment Of New Zealand
The environment of New Zealand is characterised by an endemic flora and fauna which has evolved in near isolation from the rest of the world. The main islands of New Zealand span two biomes, Temperate climate, temperate and Subtropical climate, subtropical, complicated by large mountainous areas above the tree line.Walter, H. & Breckle, S-W. (2002). ''Walter's Vegetation of the Earth: The Ecological Systems of the Geo-Biosphere''. New York: Springer-Verlag, p. 86 There are also New Zealand Subantarctic Islands, numerous smaller islands which extend into the subantarctic. The prevailing weather systems bring significantly more rain to the west of the country. New Zealand's territorial waters cover a much larger area than its landmass and extend over the continental shelf and abyssal plateau in the South Pacific Ocean, Tasman Sea and Southern ocean. Historically having an isolated and endemic ecosystem far into modernity, the arrival of Polynesians about 1300 AD and then later E ...

Lake Taupō
Lake Taupō (also spelled Taupo; or ) is a large crater lake in New Zealand's North Island, located in the caldera of Taupō Volcano. The lake is the namesake of the town of Taupō, which sits on a bay in the lake's northeastern shore. With a surface area of , it is the largest lake by surface area in New Zealand, and the second largest freshwater lake by surface area in geopolitical Oceania after Lake Murray in Papua New Guinea. Motutaiko Island lies in the southeastern area of the lake. Geography Lake Taupō has a perimeter of approximately and a maximum depth of . It is drained by the Waikato River (New Zealand's longest river), and its main tributaries are the Waitahanui River, the Tongariro River, and the Tauranga Taupō River. It is a noted trout fishery with stocks of introduced brown and rainbow trout. The level of the lake is controlled by Mercury Energy, the owner of the eight hydroelectric dams on the Waikato River downstream of Lake Taupō, using gates b ...

Subtropical
The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones immediately to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Geographical zone#Temperate zones, temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° to 40° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical climate, humid subtropical (Köppen climate classification: Cfa/Cwa), where rainfall is often concentrated in the warmest months, for example list of regions of China, Southeast China and the Southeastern United States, and Mediterranean climate, dry summer or Mediterranean climate (Köppen climate classification: Csa/Csb), where seasonal rainfall is concentrated in the cooler ...

Mackenzie Basin
The Mackenzie Basin (), popularly and traditionally known as the Mackenzie Country, is an elliptical intermontane river basin, basin located in the Mackenzie District, Mackenzie and Waitaki Districts, near the centre of the South Island of New Zealand. It is the largest such basin in New Zealand. Historically famous mainly for sheep farming, the sparsely populated area is now also a popular tourism destination. The basin was named in the 1850s by and after James Mckenzie (outlaw), James Mckenzie, a shepherd and would-be farmer of Scottish origin. Mckenzie was captured for allegedly stealing sheep; he herded his flocks in what was then an area almost totally empty of any human habitation, though Māori people, Māori previously lived there intermittently. After his capture, the area was soon divided up amongst new sheep pasture stations in 1857. Geography The basin extends approximately north to south, and east to west. The Southern Alps constitute its western edge. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Otago
Central Otago is an area located in the inland part of the Otago region in the South Island of New Zealand. The motto for the area is "A World of Difference". The area is dominated by mountain ranges and the upper reaches of the Clutha River and tributaries. The wide flat plateau of the Maniototo which lies between the upper reaches of the Taieri River and the Clutha's northern tributary the Manuherikia is also part of Central Otago. Characterised by cold winters and hot, dry summers, the area is only lightly populated. First significant European occupation came with the discovery of gold at Gabriel's Gully near Lawrence in 1861, which led to the Otago gold rush. Other towns and villages include Alexandra, Bannockburn, Clyde, Cromwell, Millers Flat, Naseby, Omakau, Ranfurly, Roxburgh, St. Bathans, and Wedderburn. Since the 19th century, most of the area's economic activity has centred on sheep, stone fruit, and tourism. In recent years, deer farms and viney ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * ...

West Coast, New Zealand
The West Coast () is a regions of New Zealand, region of New Zealand on the west coast of the South Island. It is administered by the West Coast Regional Council, and is known co-officially as Te Tai Poutini. It comprises the Territorial authorities of New Zealand, territorial authorities of Buller District, Grey District and Westland District. The principal towns are Westport, New Zealand, Westport, Greymouth and Hokitika. The region, one of the more remote areas of the country, is also the most sparsely populated. With a population of just 32,900 people, the West Coast is the least populous region in New Zealand. The population in the region grew by 0.4% over the year to July 2023. The region has a rich and important history. The land itself is ancient, stretching back to the Carboniferous period; this is evident by the amount of carboniferous materials naturally found there, especially coal. First settled by Ngāi Tahu, Kāi Tahu in approximately 1200 AD, the area was famous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Alps
The Southern Alps (; officially Southern Alps / Kā Tiritiri o te Moana) are a mountain range extending along much of the length of New Zealand, New Zealand's South Island, reaching its greatest elevations near the range's western side. The name "Southern Alps" generally refers to the entire range, although separate names are given to many of the smaller ranges that form part of it. The range includes the South Island's Main Divide, which separates the drainage basin, water catchments of the more heavily populated eastern side of the island from those on the west coast. Politically, the Main Divide forms the boundary between the Marlborough Region, Marlborough, Canterbury Region, Canterbury and Otago regions of New Zealand, regions to the southeast and the Tasman Region, Tasman and West Coast, New Zealand, West Coast regions to the northwest. Names The Māori language, Māori name of the range is , meaning "the Fata Morgana (mirage), Mirage of the Ocean". The English people, ...

Soil Formation
Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order ( anisotropy) within soils. These alterations lead to the development of layers, termed soil horizons, distinguished by differences in color, structure, texture, and chemistry. These features occur in patterns of soil type distribution, forming in response to differences in soil forming factors. Pedogenesis is studied as a branch of pedology, the study of soil in its natural environment. Other branches of pedology are the study of soil morphology and soil classification. The study of pedogenesis is important to understanding soil distribution patterns in current ( soil geography) and past ( paleopedology) geologic periods. Overview Soil develops through a series of changes. The starting point is weathering of freshly accumulated parent material. A variety of soil microbes ...

Northland Peninsula
The Northland Peninsula, called the North Auckland Peninsula in earlier times, is in the far north of the North Island of New Zealand. It is joined to the rest of the island by the Auckland isthmus, a narrow piece of land between the Waitematā Harbour and the Manukau Harbour in the middle of the Auckland metropolitan area. The peninsula is not conterminous with the local government area of Northland Region, which occupies the northern 80% of the peninsula, as the southern section is administratively part of the Auckland Region. Geology The peninsula formed as an island 22 million years ago, when the area was uplifted due to interactions between the Pacific Plate and Australian Plate. Between 25 and 22 million years ago, Northland and the East Cape were adjacent, with the East Cape moving south-east due to tectonic forces. Much of the land of Northland is an allochthon, a large block of land formed elsewhere and moved into its current position. When Northland was uplifte ...

Ultramafic Rock
Ultramafic rocks (also referred to as ultrabasic rocks, although the terms are not wholly equivalent) are igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are usually composed of greater than 90% mafic minerals (dark colored, high magnesium and iron content). Earth's mantle is composed of ultramafic rocks. Ultrabasic is a more inclusive term that includes igneous rocks with low silica content that may not be extremely enriched in Fe and Mg, such as carbonatites and ultrapotassic igneous rocks. Intrusive ultramafic rocks Intrusive ultramafic rocks are often found in large, layered ultramafic intrusions where differentiated rock types often occur in layers. Such cumulate rock types do not represent the chemistry of the magma from which they crystallized. The ultramafic intrusives include the dunites, peridotites and pyroxenites. Other rare varieties include troctolite which has a greater pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Encyclopedia Of New Zealand
''Te Ara: The Encyclopedia of New Zealand'' is an online encyclopedia established in 2001 by the New Zealand Government's Ministry for Culture and Heritage. The web-based content was developed in stages over the next several years; the first sections were published in 2005, and the last in 2014 marking its completion. ''Te Ara'' means "the pathway" in the Māori language, and contains over three million words in articles from over 450 authors. Over 30,000 images and video clips are included from thousands of contributors. History New Zealand's first recognisable encyclopedia was ''The Cyclopedia of New Zealand'', a commercial venture compiled and published between 1897 and 1908 in which businesses or people usually paid to be covered. In 1966 the New Zealand Government published ''An Encyclopaedia of New Zealand'', its first official encyclopedia, in three volumes. Although now superseded by ''Te Ara'', its historical importance led to its inclusion as a separate digital reso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
