Sonchus Kirkii
''Sonchus kirkii'', also known as New Zealand sow thistle, or shore puha is a herb in the Asteraceae family. It grows in coastal New Zealand. Appearance The shore puha has green leaves extending upwards with spiky sides. On the top is a yellow flower. The shore puha can grow up to 15-30 centimeters tall. Occasionally it grows up to 100 centimeters. Conservation status The conservation status of the shore puha is currently at "declining" and its Conservation status, umbrella category is "at risk". Threats Other species of weeds that grow faster may be the reason for the shore puha to be at a declining status as it is outcompeted. The sowthistles ''Sonchus asper'' and ''Sonchus oleraceus'' can take over the habitats that the shore puha prefer and colonizing the area quicker. Up until the mid-1980s the shore puha was common, but since then its numbers have been declining.

New Zealand Threat Classification System
The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some shortcomings for the unique requirements of conservation ranking in New Zealand. plants, animals, and fungi are evaluated, though the lattermost has yet to be published. Algae were assessed in 2005 but not reassessed since. Other protists have not been evaluated. Categories Species that are ranked are assigned categories: ;Threatened This category has three major divisions: ::*Nationally Critical - equivalent to the IUCN category of Critically endangered ::*Nationally Endangered - equivalent to the IUCN category of Endangered ::*Nationally Vulnerable - equivalent to the IUCN category of Vulnerable ;At Risk This has four categories: ::*Declining ::*Recovering ::*Relict ::*Naturally Uncommon ;Other categories ;;Introduced and Natu ...

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 ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more t ...

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 List of islands of New Zealand, smaller islands. It is the List of island countries, 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 of New Zealand, 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds.

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Māori Language
Māori (), or ('the Māori language'), also known as ('the language'), is an Eastern Polynesian language spoken by the Māori people, the indigenous population of mainland New Zealand. Closely related to Cook Islands Māori, Tuamotuan, and Tahitian, it gained recognition as one of New Zealand's official languages in 1987. The number of speakers of the language has declined sharply since 1945, but a Māori-language revitalisation effort has slowed the decline. The 2018 New Zealand census reported that about 186,000 people, or 4.0% of the New Zealand population, could hold a conversation in Māori about everyday things. , 55% of Māori adults reported some knowledge of the language; of these, 64% use Māori at home and around 50,000 people can speak the language "very well" or "well". The Māori language did not have an indigenous writing system. Missionaries arriving from about 1814, such as Thomas Kendall, learned to speak Māori, and introduced the Latin alphabet. ...

Dunedin Botanic Garden
The Dunedin Botanic Garden (known in local slang as the "Botans", "Botang", Botanic or Botanical Gardens) is located at the northern end of central Dunedin, in the South Island of New Zealand. The garden is close to the University of Otago and one of the city's most historic cemeteries, the Northern Cemetery, on a spur of Signal Hill and on the river plain immediately below it. The location of the gardens makes them popular with university students, as they lie between the university and the mouth of North East Valley, which houses a substantial proportion of the city's tertiary students. The gardens are also easily accessible by road from the city centre, being located close to the northern end of the city's main business street, George Street, and at the northern end of the city's one-way street system, part of State Highway 1. A small suburban shopping centre lies close to the garden's northern entrance at an intersection known as The Gardens Corner. The garden The two parts ...
