Wilding Conifers
Wilding conifers, also known as wilding pines, are invasive trees in the high country of New Zealand. Millions of dollars are spent on controlling their spread. In the South Island they threaten 210,000 hectares of public land administered by the Department of Conservation. They are also present on privately owned land and other public land such as roadsides. The wilding conifers are considered to be a threat to biodiversity, farm productivity and to landscape values. Since they often invade tussock grasslands – which are characterised by low-lying vegetation that is considered to be a natural environment – the tall trees become a prominent and unwanted feature. Species There are ten main species that have become wildings:''Wilding conifers – New Zealand history and research background'', a presentation by Nick Ledgard at the "Managing wilding conifers in New Zealand – present and future" workshop (2003) * Bishop pine (''Pinus muricata'') * Corsican pine (''Pinus nigr ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Pinus Sylvestris
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US) or Baltic pine, is a species of tree in the pine family Pinaceae that is native to Eurasia. It can readily be identified by its combination of fairly short, blue-green leaves and orange-red bark. Description ''Pinus sylvestris'' is an evergreen coniferous tree growing up to in height and in trunk diameter when mature, exceptionally over tall and in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old tree growing in Estonia which stands at . The lifespan is normally 150–300 years, with the oldest recorded specimens in Lapland, Northern Finland over 760 years. The bark is thick, flaky and orange-red when young to scaly and gray-brown in maturity, sometimes retaining the former on the upper portion.Trees for LifeSpecies profile: Scots pine/ref> The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of ...

Kaweka Forest Park
Kaweka Forest Park is in the Hawke's Bay region of New Zealand, adjacent to Kaimanawa Forest Park. This region of the central North Island contains large tracts of pine plantations, some of them also within the park, and as a consequence, invasive wilding conifers are present throughout the park. The highest peak in the park is Kaweka at . The Mangatutu Hot Springs, in the vicinity of the Mohaka River, are in the park. History In the late 1800s European settlers cleared the land for farming. However, the steep terrain and poor soil made it difficult to farm. By 1900 farming had ceased, and the park became a State Forest in the 1960s. During this period it was replanted with exotic pine trees and was turned into a Forest Park in 1972.

Territorial Authority
Territorial authorities are the second tier of local government in New Zealand, below regional councils. There are 67 territorial authorities: 13 city councils, 53 district councils and the Chatham Islands Council. District councils serve a combination of rural and urban communities, while city councils administer the larger urban areas.City councils serve a population of more than 50,000 in a predominantly urban area. Five territorial authorities (Auckland, Nelson, Gisborne, Tasman and Marlborough) also perform the functions of a regional council and thus are unitary authorities. The Chatham Islands Council is a ''sui generis'' territorial authority that is similar to a unitary authority. Territorial authority districts are not subdivisions of regions, and some of them fall within more than one region. Regional council areas are based on water catchment areas, whereas territorial authorities are based on community of interest and road access. Regional councils are responsib ...

Kingston, New Zealand
Kingston is a small town at the southernmost end of Lake Wakatipu, just north of the border of Otago and Southland, in New Zealand's South Island. It is 47 kilometres south of Queenstown by a road, "The Devil's Staircase", which winds between the lake to the west and The Remarkables mountains to the east. It is 70 kilometres north of Lumsden, and close to the headwaters of the Mataura River. History Kingston was originally named 'St Johns' after police commissioner St. John Branigan. Demographics Kingston is described by Statistics New Zealand as a rural settlement. It covers . It is part of the much larger Kingston statistical area.

Athol, New Zealand
Athol is a small town in Southland, New Zealand. It is located on , 55 km south of Queenstown, halfway between Lumsden and Kingston on the Southern Scenic Route. Farming has always been very important in the district, though in earlier times gold mining, centred on nearby Nokomai, was also significant. In recent decades tourist numbers have grown. The Mataura River is well known for the quality of its brown trout fishing, and the Around the Mountains Cycle Trail, opened in November 2014, has further boosted visitor figures. Name There is some uncertainty over how Athol received its name. The first record of it is when the township was surveyed in 1863. Several suggestions have been made. One is that it was named after Harry Athol, the proprietor of the first hotel. There is no early record of a person of this name and there may be a confusion with Harry Arthur, who ran the Athol accommodation house in the 1860s. Another is that it was named after the home district in Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pesticide Drift
Pesticide drift refers to the unintentional diffusion of pesticides and the potential negative effects of pesticide application, including off-target contamination due to spray drift as well as runoff from plants or soil. This can lead to damage in human health, environmental contamination, and property damage. Types With placement (localised) spraying of broad spectrum pesticides, wind drift must be minimised, and considerable efforts have been made to quantify and control spray drift from hydraulic nozzles. Conversely, wind drift is also an efficient mechanism for moving droplets of an appropriate size range to their targets over a wide area with ultra-low volume (ULV) spraying. Himel (1974) made a distinction between exo-drift (the transfer of spray out of the target area) and endo-drift, where the active ingredient (AI) in droplets falls into the target area, but does not reach the biological target. Endo-drift is volumetrically more significant and may therefore cause grea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southland, New Zealand
Southland ( mi, Murihiku) is New Zealand's southernmost region. It consists mainly of the southwestern portion of the South Island and Stewart Island/Rakiura. It includes Southland District, Gore District and the city of Invercargill. The region covers over 3.1 million hectares and spans over 3,400 km of coast. History The earliest inhabitants of Murihiku (meaning "the last joint of the tail") were Māori of the Waitaha iwi, followed later by Kāti Māmoe and Kāi Tahu. Waitaha sailed on the Uruao waka, whose captain Rakaihautū named sites and carved out lakes throughout the area. The Takitimu Mountains were formed by the overturned Kāi Tahu waka Tākitimu. Descendants created networks of customary food gathering sites, travelling seasonally as needed, to support permanent and semi-permanent settlements in coastal and inland regions. In later years, the coastline was a scene of early extended contact between Māori and Europeans, in this case sealers, whalers ...

Chainsaw
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively.
