Gorse In New Zealand
Gorse ('' Ulex europaeus'') was introduced to New Zealand in the early stages of European settlement. It is now a major invasive plant species with millions of dollars spent on its control. Introduction to New Zealand Introduced from Western Europe in the very early stages of European settlement, it was recorded by Charles Darwin during his voyage through New Zealand waters in 1835 as growing in hedges in the Bay of Islands. Its spread and development as a weed in New Zealand's temperate climate was rapid, but settlers failed to recognise the threat; gorse seed continued to be imported and plantings deliberately established into the 1900s. Uses Gorse has been used for hedges and windbreaks on the Canterbury Plains since the 1850s. These windbreaks have a combined length of 300,000 kilometres. Gorse has been found to form a useful nursery for many species for native bush regeneration. When young, gorse bushes are very dense. As they grow older, they become 'leggy', and pr ...

Gorse On Farmland, Wellington, NZ
''Ulex'' (commonly known as gorse, furze, or whin) is a genus of flowering plants in the family (biology), family Fabaceae. The genus comprises about 20 species of Thorns, spines, and prickles, thorny evergreen shrubs in the subfamily Faboideae of the pea family Fabaceae. The species are native to parts of western Europe and northwest Africa, with the majority of species in Iberian Peninsula, Iberia. Gorse is closely related to the Broom (shrub), brooms and like them has green stems and very small leaves and is adapted to dry growing conditions. However it differs in its extreme thorniness, the shoots being modified into branched Thorns, spines, and prickles, thorns long, which almost wholly replace the leaves as the plant's functioning photosynthesis, photosynthetic organs. The leaf, leaves of young plants are Leaf shape, trifoliate, but in mature plants they are reduced to scales or small Thorns, spines, and prickles, spines. All the species have yellow flowers, generally sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulex Europaeus
''Ulex europaeus'', the gorse, common gorse, furze or whin, is a species of flowering plant in the family Fabaceae, native to the British Isles and Western Europe. Description Growing to tall, it is an evergreen shrub. The young stems are green, with the shoots and leaves modified into green spines, long. Young seedlings produce normal leaves for the first few months; these are trifoliate, resembling a small clover leaf. The solitary flowers are yellow, long, with the pea-flower structure typical of the Fabaceae; they are produced throughout the year, but mainly over a long period in spring. They are coconut-scented. The fruit is a legume (pod) long, dark purplish-brown, partly enclosed by the pale brown remnants of the flower; the pod contains 2–3 small blackish, shiny, hard seeds, which are ejected when the pod splits open in hot weather. Seeds remain viable for 30 years. Like many species of gorse, it is often a fire-climax plant, which readily catches fire but re-g ...

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 ...

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 ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Of Islands
The Bay of Islands is an area on the east coast of the Far North District of the North Island of New Zealand. It is one of the most popular fishing, sailing and tourist destinations in the country, and has been renowned internationally for its big-game fishing since American author Zane Grey publicised it in the 1930s. It is north-west of the city of Whangarei. Cape Reinga, at the northern tip of the country, is about by road further to the north-west. Geography The bay itself is an irregularly-shaped -wide, drowned valley system and a natural harbour. It contains 144 islands, of which the largest is Urupukapuka, and numerous peninsulas and inlets. The three largest inlets are Waikare Inlet in the south, and Kerikeri and Te Puna (Mangonui) inlets in the north-west. The Purerua Peninsula, north of Te Puna Inlet, separates the north-western part of the bay from the Pacific Ocean, and Cape Brett Peninsula extends into the ocean at the eastern end of the bay. The biggest t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canterbury Plains
The Canterbury Plains () are an area in New Zealand centred in the Mid Canterbury, to the south of the city of Christchurch in the Canterbury region. Their northern extremes are at the foot of the Hundalee Hills in the Hurunui District, and in the south they merge into the plains of North Otago beyond the Waitaki River. The smaller Amuri Plain forms a northern extension of the plains. Geology The Canterbury Plains were formed from Quaternary moraine gravels transported from the Southern Alps and deposited here during glacial periods in the late Pleistocene approximately 3 million to 10,000 years ago. The alluvial gravels were then reworked as shingle fans of several of the larger rivers, notably the Waimakariri, the Rakaia, the Selwyn / Waikirikiri, and the Rangitata. Part of the Canterbury-Otago tussock grasslands, the land is suitable for moderately intensive livestock farming but is prone to droughts, especially when the prevailing wind is from the northwest. At these time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hinewai Reserve
Hinewai Reserve is a private nature reserve on Banks Peninsula in New Zealand. Description Hinewai Reserve started off as a 109 ha block of farmland bought by the Maurice White Native Forest Trust in September 1987 and is now 1230 ha of gorse and regenerating native bush. The reserve was completely forested in pre-human times but, as with much of Banks Peninsula, the forest cover was severely reduced, especially after European settlement. The transformation from open pasture and gorse to native vegetation has occurred rapidly. The reserve includes 20 walking tracks open to the public, including part of the Banks Peninsula Track. The reserve is managed for the Trust by botanist Hugh Wilson, who hand-writes and illustrates a newsletter about the reserve, ''Pīpipi'', which the Trust publishes several times a year. One-third of the reserve was burnt on 13 July 2011, possibly due to a lightning strike. In 2017 the Hinewai newsletter reported that there was hardly anything notice ...

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture In New Zealand
In New Zealand, agriculture is the largest sector of the tradable economy. The country exported NZ$46.4 billion worth of agricultural products (raw and manufactured) in the 12 months to June 2019, 79.6% of the country's total exported goods. The agriculture, forestry and fisheries sector directly contributed $12.653 billion (or 5.1%) of the national GDP in the 12 months to September 2020, and employed 143,000 people, 5.9% of New Zealand's workforce, as of the 2018 census. New Zealand is unique in being the only developed country to be totally exposed to the international markets since subsidies, tax concessions and price supports for the agricultural sector were removed in the 1980s. However, as of 2017, the New Zealand Government still provides state investment in infrastructure which supports agriculture. Pastoral farming is the major land use but there are increases in land area devoted to horticulture. New Zealand is a member of the Cairns Group, which is seeking to hav ...
