Didymo In New Zealand
__NOTOC__ In 2004 '' Didymosphenia geminata'', a diatom commonly known as didymo or rock snot, was discovered in New Zealand, the first time it was found in the Southern Hemisphere. To restrict its spread, the whole of the South Island of New Zealand was declared a controlled area in December 2005. All items, such as boats, fishing gear, clothing, and vehicles, that have been in a stream, river or lake, must be cleaned before they enter another waterway. Biosecurity New Zealand working with Environment Southland, AgriQuality and Fish and Game New Zealand launched an extensive public awareness campaign to encourage river users to clean their equipment after use in affected waterways. This campaign was highly successful, with 99% of freshwater users surveyed in 2008 in the South Island being aware of didymo. Adverse effects Didymo can have a notable impact on the insects that are a food source for many species of fish. It can form massive algal blooms. It makes riverbeds slipper ...

Didymo Sign On Gate
''Didymosphenia geminata'', commonly known as didymo or rock snot, is a species of diatom that produces nuisance growths in freshwater rivers and streams with consistently cold water temperatures and low nutrient levels. It is native to the northern hemisphere, and considered an invasive species in Australia, Argentina, New Zealand, and Chile. Even within its native range, it has taken on invasive characteristics since the 1980s. It is not considered a significant human health risk, but it can affect stream habitats and sources of food for fish and make recreational activities unpleasant. This microscopic algae, alga can be spread in a single drop of water. Description ''Didymosphenia geminata'' is a diatom, which is a type of single-celled organism unique for their silica (SiO2) cell walls. The life history of diatoms includes both vegetative and sexual reproduction, though the sexual stage is not yet documented in this species. Although it is symmetric only along the apical a ...

Tongariro River
The Tongariro River is a river in the North Island of New Zealand. The part of the Waikato River from the Waihohonu Stream, down to Lake Taupo, was formally named the Tongariro River in 1945. The river originates in the Central Plateau of the North Island where it is fed by numerous tributaries (such as the Whitikau, Poutu, and Mangamawhitiwhiti streams) that flow off the surrounding hill ranges and mountains such as Mount Ruapehu. It then winds its way north, through the township of Turangi before entering Lake Taupo via a number of river mouths. The minimum volume of water flowing down the lower Tongariro River ranges from approximately (recorded at the upper rivers Poutu Intake) to (recorded at the lower rivers Major Jones Pool). This volume can substantially increase due to catchment of rainfall by the surrounding mountains and hill ranges. Recreation Fishing The Tongariro River is New Zealand's most fished river, and is a drawcard for anglers the world over, who come ...

Department Of Conservation (New Zealand)
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 Authority (NZCA) is provided to advise DOC and its ministers. In addition there are 15 conservation boards for different areas around the country that provide for interaction between DOC and the public. Function Overview The department was formed on 1 April 1987, as one of several reforms of the public service, when the ''Conservation Act 1987'' was passed to integrate some functions of the Department of Lands and Survey, the Forest Service and the Wildlife Service. This act also set out the majority of the department's responsibilities and roles. As a consequence of Conservation Act all Crown land in New Zealand designated for conservation and protection became managed by the Department of Conservation. This is about 30% of New Z ...

Conservation In New Zealand
Conservation in New Zealand has a history associated with both Māori and Europeans. Both groups of people caused a loss of species and both altered their behaviour to a degree after realising their effect on indigenous flora and fauna. Protected areas New Zealand has thirteen national parks, forty four marine reserves and many other protected areas for the conservation of biodiversity. The introduction of many invasive species is threatening the indigenous biodiversity, since the geographical isolation of New Zealand led to the evolution of plants and animals that did not have traits to protect against predation. New Zealand has a high proportion of endemic species, so pest control is generally regarded as a high priority. The New Zealand Department of Conservation administers approximately 30% of New Zealand's land, along with less than 1% of the country's marine environment, for conservation and recreational purposes. It has published lists, under the New Zealand Threat C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species In New Zealand
A number of introduced species, some of which have become invasive species, have been added to New Zealand's native flora and fauna. Both deliberate and accidental introductions have been made from the time of the first human settlement, with several waves of Polynesian people at some time before the year 1300, followed by Europeans after 1769. Almost without exception, the introduced species have been detrimental to the native flora and fauna but some, such as farmed sheep and cows and the clover upon which they feed, now form a large part of the economy of New Zealand. Registers, lists and indexes of species that are invasive, potentially invasive, or a threat to agriculture or biodiversity are maintained by Biosecurity New Zealand. Animal species Many invasive animal species are listed in schedules 5 and 6 of the Wildlife Act 1953. Those in Schedule 5 have no protection and may be killed. Those in Schedule 6 are declared to be noxious animals and subject to the Wild A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riuwaka River
The Riuwaka River, formerly known as the Riwaka River, is located in the Nelson region in the northwest of New Zealand's South Island. It flows for 20 kilometres, entering Tasman Bay / Te Tai-o-Aorere close to the town of Riwaka, 10 kilometres north of Motueka. The valleys of the Riuwaka and nearby Tākaka River form part of the pass over which the only road between Tasman Bay and Golden Bay runs. For part of its journey, the river flows underground through limestone caves, returning to the open air at ''The Riuwaka Resurgence''. This spot is popular with both holidaymakers and divers, as the water is always crystal clear, and is very cold even in the heat of mid-summer. The name of the river was officially altered to Riuwaka River in August 2014, following the Treaty of Waitangi settlements between the Crown and local iwi Ngāti Rārua and Te Atiawa o Te Waka-a-Māui Te Atiawa o Te Waka-a-Māui is a Māori iwi (tribe) in the upper South Island of New Zealand.

Waimakariri River
The Waimakariri River is one of the largest rivers in Canterbury, on the eastern coast of New Zealand's South Island. It flows for in a generally southeastward direction from the Southern Alps across the Canterbury Plains to the Pacific Ocean. The river rises on the eastern flanks of the Southern Alps, eight kilometres southwest of Arthur's Pass. For much of its upper reaches, the river is braided, with wide shingle beds. As the river approaches the Canterbury Plains, it passes through a belt of mountains, and is forced into a narrow canyon (the Waimakariri Gorge), before reverting to its braided form for its passage across the plains. It enters the Pacific north of Christchurch, near the town of Kaiapoi. Instead of being unoccupied Crown land as are most New Zealand river beds, the bed of the Waimakariri River is vested in the Canterbury Regional Council (Environment Canterbury). Name The name ''Waimakariri'' comes from the Māori words ''wai'', meaning ''water'', and ''makari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longjawed Galaxias
The longjawed galaxias (''Galaxias prognathus'') is a galaxiid of the genus ''Galaxias'', found only in rivers and streams at mid to high altitudes on the eastern side of the Southern Alps in the South Island of New Zealand. It grows to a length of up to 9 cm. Longjawed galaxias are slender and elongate, having coloration consisting of spots and indistinct bands of various shades of brown and grey. The single dorsal and anal fins are about two thirds of the way along the body. Like all galaxiids it lacks scales and has a thick, leathery skin covered with mucus Mucus ( ) is a slippery aqueous secretion produced by, and covering, mucous membranes. It is typically produced from cells found in mucous glands, although it may also originate from mixed glands, which contain both serous and mucous cells. It is .... The lower jaw is forward of the upper, giving rise to its common name. References * NIWA June 2006 longjawed galaxias Endemic freshwater fish of New Zealand F ...

Wrybill
The wrybill or (in Māori) ngutuparore (''Anarhynchus frontalis'') is a species of plover endemic to New Zealand. It is the only species of bird in the world with a beak that is bent sideways in one direction, always to the right (in the crossbills, e.g. ''Loxia pytyopsittacus'', the tips of the upper and lower mandibles cross because they are bent sideways in opposite directions, sometimes left over right and sometimes right over left). A 2015 study found it to be within the ''Charadrius'' clade, with other New Zealand plovers its closest relatives; the nearest being the New Zealand dotterel or New Zealand plover (''Charadrius obscurus''), and then the double-banded plover or banded dotterel (''Charadrius bicinctus''). It lays its eggs among the rocks along rivers and distracts intruders by pretending to be in distress and moving away from its clutch. It is rated as vulnerable on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species. Taxono ...

Black-fronted Tern
The black-fronted tern (''Chlidonias albostriatus''), also known as sea martin, ploughboy, inland tern, riverbed tern or tarapiroe,Rod Morris and Alison Ballance, ''"Rare Wildlife of New Zealand"'', Random House, 2008 is a small tern generally found in or near bodies of fresh water in New Zealand, where it forages for freshwater fish, arthropods and worms. It has a predominantly grey plumage. Restricted to breeding in the eastern regions of the South Island, it is declining and threatened by introduced mammals and birds. It is rated as endangered on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species. Taxonomy German naturalist Johann Reinhold Forster described the black-fronted tern from a specimen collected at Queen Charlotte Sound, Marlborough in 1832, giving it the binomial name ''Sterna antarctica'', however the name had already been used for the Antarctic tern by French naturalist René Lesson the previous year.

Rangitata River
The Rangitata River is one of the braided rivers that helped form the Canterbury Plains in southern New Zealand. It flows southeast for from the Southern Alps (New Zealand), Southern Alps, entering the Pacific Ocean northeast of Timaru. The river has a catchment area of , and a mean annual flow of at Klondyke. The Māori language, Māori name "Rangitata" (Rakitata) has been variously translated as "day of lowering clouds", "close sky", and "the side of the sky". The river formed the Rangitata Valley, in the center of the Southern Alps, and the on-location photography of the Edoras set from ''The Lord of the Rings: The Two Towers'', and ''The Lord of the Rings: The Return of the King, The Return of the King'' was filmed in this valley, on and around Mount Sunday. Several remote sheep stations are located near Mount Sunday. These include Mesopotamia (station), Mesopotamia, Mt Potts, and Erewhon. Erewhon was named by Samuel Butler (novelist), Samuel Butler who was the first white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
