Invasive Species Of New Zealand Origin
Some species endemism, endemic to New Zealand are causing problems in other countries, similar to the way introduced species in New Zealand cause problems for agriculture and Biodiversity of New Zealand, indigenous biodiversity. Animals *The New Zealand mud snail (''Potamopyrgus antipodarum'') is an invasive species in many countries and has been present in Europe since 1859.Čejka T., Dvořák L. & Košel V. 2008Present distribution of ''Potamopyrgus antipodarum'' (Gray, 1843) (Mollusca: Gastropoda) in the Slovak Republic - Malacologica Bohemoslovaca, 7: 21-25.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acaena Novae-zelandiae
''Acaena novae-zelandiae'', commonly known as red bidibid, bidgee widgee, buzzy and piri-piri bur, is a small herbaceous, prostrate perennial, native to New Zealand, Australia and New Guinea, of the family Rosaceae. Description ''Acaena novae-zelandiae'' is a small herbaceous perennial. It is stoloniferous with prostrate stems of 1.5 – 2 mm diameter. Damage to stolons encourages new shoots to be produced. It has imparipinnate leaves, with 9–15 toothed, oblong leaflets, which are approximately 2 –11 cm long. The adaxial surface of the leaves is dark green and shiny, and the abaxial surface is hairy and glaucous green in colouration. The rachis of the leaves is often red. The scape is 10 – 15 cm long and bears a globular, terminal inflorescence, of 20 – 25 mm diameter, with 70 – 100 flowers. The flowers lack petals and can range in colour from green to white or purple. The flowers are wind pollinated. Each flower produces one achene, bearing ...

Invasive Species Of Australian Origin
There are a number of Australian species that have become invasive when introduced into outside Australia or outside Oceania. Animals The Australian magpie was introduced into New Zealand and are considered to be a pest because of attacks on humans and a possible effect on the native bird population. The common brushtail possum was introduced to New Zealand to start a fur industry, and spread nationwide. With no natural controls they have severe impact by feeding on native plant species and also prey on native animals species as well. Possums have also been observed eating the eggs of nesting birds such as the kererū, tūī, and kākā. They are a carrier of tuberculosis which they spread to pasture and hence livestock. Control of them has been an ongoing project of regional councils, the Department of Conservation, Forest and Bird, and various other wildlife preservation organizations.

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] |

Golden Gate National Recreation Area
The Golden Gate National Recreation Area (GGNRA) is a U.S. National Recreation Area protecting of ecologically and historically significant landscapes surrounding the San Francisco Bay Area. Much of the park is land formerly used by the United States Army. GGNRA is managed by the National Park Service and is the most visited unit of the National Park system in the United States, with more than 15 million visitors a year. It is also one of the largest urban parks in the world, with a size two-and-a-half times that of the consolidated city and county of San Francisco. The park is not one continuous locale, but rather a collection of areas that stretch from southern San Mateo County to northern Marin County, and includes several areas of San Francisco. The park is as diverse as it is expansive; it contains famous tourist attractions such as Muir Woods National Monument, Alcatraz, and the Presidio of San Francisco. The GGNRA is also home to over 3,000 plant and animal species, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phormium Tenax
''Phormium tenax'' (called flax in New Zealand English; in Māori; New Zealand flax outside New Zealand; and New Zealand hemp in historical nautical contexts) is an evergreen perennial plant native to New Zealand and Norfolk Island that is an important fibre plant and a popular ornamental plant.Roger Holmes and Lance Walheim. 2005. ''California Home Landscaping'', Creative Homeowner Press The plant grows as a clump of long, straplike leaves, up to two metres long, from which arises a much taller flowering shoot, with dramatic yellow or red flowers. The fibre has been widely used since the arrival of Māori to New Zealand, originally in Māori traditional textiles and also in rope and sail making after the arrival of Europeans until at least WWII. It is an invasive species in some of the Pacific Islands and in Australia. The blades of the plant contain cucurbitacins, which are poisonous to some animals, and some of them are among the bitterest tastes to humans. Etymology The ...

Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management, nature reserves, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introduced as ornamental plants for horticultural use. Some "noxious weeds", such as ragwort, produce copious amou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
