Waituna Lagoon
__NOTOC__ The Waituna Lagoon is on the southern coastline of the South Island of New Zealand. It forms part of the Awarua Wetland, a Ramsar site that was established in 1976. It gives it name to waituna, a type of ephemeral coastal lake. The lagoon is an important habitat for resident and migratory birds with seventy three different species being recorded. The expansion in the area of ''Leptocarpus (plant), Leptocarpus'' rushes that has been observed over a 47-year period in the lagoon have been attributed to artificial openings of the lagoon to the sea, and the increase in sedimentation. The lagoon is largely unmodified by human activity but there are elevated nutrient levels and sedimentation with a fear that it may lead to eutrophication. Recreational use Waituna Lagoon is a common fishing and game bird hunting spot. There is a good supply of brown trout in the lake/lagoon and its tributaries with a daily limit of two trout per person per day. The fishing season runs from 1 ...

South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and services. ...

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 ...

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invercargill
Invercargill ( , mi, Waihōpai is the southernmost and westernmost city in New Zealand, and one of the southernmost cities in the world. It is the commercial centre of the Southland region. The city lies in the heart of the wide expanse of the Southland Plains to the east of the Ōreti or New River some north of Bluff, which is the southernmost town in the South Island. It sits amid rich farmland that is bordered by large areas of conservation land and marine reserves, including Fiordland National Park covering the south-west corner of the South Island and the Catlins coastal region. Many streets in the city, especially in the centre and main shopping district, are named after rivers in Scotland. These include the main streets Dee and Tay, as well as those named after the Tweed, Forth, Tyne, Esk, Don, Ness, Yarrow, Spey, Eye and Ythan rivers, amongst others. The 2018 census showed the population was 54,204, up 2.7% on the 2006 census number and up 4.8% on the 2013 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Awarua Wetland
The Awarua Wetland is a peatland area of in the Southland Region of New Zealand. The site, which was initially an area of about , was designated as having international significance under the Ramsar Convention in 1976, using the name Waituna Wetlands Scientific Reserve. Conservation Minister Steve Chadwick unveiled a plaque at New River Estuary on 4 May 2008. This wetland is unique in New Zealand as it includes privately owned ground (Gamble, Nicol, and Rance families). On the northeast corner of the Toetoes Wetlands is an area of native bush of approximately , which along with other areas of bush close by was covenanted to the QEII Trust by the Nicol Family. While not a true wetland it is an area of natural vegetation with an unmodified stream flowing from the wetlands through native brush and into the Mataura river. It is a small sanctuary for the declining native fresh water fish population. Intensive farming in the catchment for the wetland has raised fears that the Waituna ...

Waituna
A waituna is a freshwater coastal lagoon on a mixed sand and gravel (MSG) beach, formed where a braided river meets a coastline affected by longshore drift. This type of waterbody is neither a true lake, lagoon nor estuary. This classification differentiates it from hapua, a type of river mouth lagoon. Both waituna and hapua are rare globally but common in New Zealand, where they are considered ecologically significant as sites of traditional Māori people, Maori food-gathering as well as for their diversity of fish and bird species. Waitnua form an interlinked chain of habitats which run the length of the east coast of the South Island: from Wairua Lagoon and Lake Grassmere in Marlborough District, Marlborough, through Lake Ellesmere, Te Waihore / Lake Ellesmere and Coopers Lagoon / Muriwai, Coopers Lagoon in central Canterbury Region, Canterbury, and Washdyke Lagoon and Wainono Lagoon in South Canterbury, to Waituna Lagoon in Southland District, Southland.

Ephemeral
Ephemerality (from the Greek word , meaning 'lasting only one day') is the concept of things being transitory, existing only briefly. Academically, the term ephemeral constitutionally describes a diverse assortment of things and experiences, from digital media to types of streams. "There is no single definition of ephemerality". With respect to unique performances, for example, it has been noted that " hemerality is a quality caused by the ebb and flow of the crowd's concentration on the performance and a reflection of the nostalgic character of specific performances". Because different people may value the passage of time differently, ephemerality may be a relative, perceptual concept: "In brief, what is short-lived may not be the object itself, but the attention we afford it".Ronald Beiner, ''Political Philosophy: What It Is and Why It Matters'' (2014), p. 10. Ephemerality and nature Geographical features An ephemeral stream is that which only exists following precipitation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eutrophication
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients deriv ...

Coastline Of New Zealand
New Zealand has of coastline making it the 9th longest in the world. The coastline borders the Tasman Sea and the Pacific Ocean. The northern and southernmost points of the coastline on the two main islands are Surville Cliffs and Slope Point respectively. Cape Reinga in the north and Bluff in the south are often incorrectly given as the extremities of the coastline on the North and South Islands. Coastal development, such as buildings and marine farms, has become contentious in recent decades. Geography The geography of the New Zealand coastline is varied. As well as sheltered sandy beaches there are rugged, remote and cliff lined sections typified by the Fiordland area. Ironsand gives the beaches on west coast of the North Island a black colouration. Pine plantation were established on some of the coastal dune sections. Woodhill, Riverhead and Bottle Lake Forest are such examples. Marram grass was planted for dune stabilisation displacing native plants such as Pingao. Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
