Vegetation Of Open Habitats In The British National Vegetation Classification System
This article gives an overview of the plant communities formed by vegetation of open habitats in the British National Vegetation Classification system. Introduction The open habitat communities of the NVC were described in Volume 5 of ''British Plant Communities'', first published in 2000, along with the three groups of maritime communities ( shingle, strandline and sand-dune communities, salt-marsh communities and maritime cliff communities). In total, 42 open habitat communities have been identified. The open habitat communities consist of eight distinct subgroups: * six arable weed and trackside communities of light, less-fertile acid soils ( OV1, OV2, OV3, OV4, OV5 and OV6) * eight arable weed and wasteland communities of fertile loams and clays (OV7 OV7, formerly known as La Onda Vaselina, is a Mexican Latin pop group formed in 1989, but it was not until the early 1990s that Onda Vaselina would begin to make their impact. La Onda Vaselina was formed with the membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminology Used In Connection With The British National Vegetation Classification
__NOTOC__ The British National Vegetation Classification or NVC is a system of classifying natural habitat types in Great Britain according to the vegetation they contain. A large scientific meeting of ecologists, botanists, and other related professionals in the United Kingdom resulted in the publication of a compendium of five books: ''British Plant Communities'', edited by John S. Rodwell, which detail the incidence of plant species in twelve major habitat types in the British natural environment. They are the first systematic and comprehensive account of the vegetation types of the country. They cover all natural, semi-natural and major artificial habitats in Great Britain (not Northern Ireland) and represent fifteen years of research by leading plant ecologists. From the data collated from the books, commercial software products have been developed to help to classify vegetation identified into one of the many habitat types found in Great Britain – these include ''MATCH' ...

British Plant Communities
''British Plant Communities'' is a five-volume work, edited by John S. Rodwell and published by Cambridge University Press, which describes the plant communities which comprise the British National Vegetation Classification. Its coverage includes all native vegetation communities and some artificial ones of Great Britain, excluding Northern Ireland Northern Ireland ( ga, Tuaisceart Éireann ; sco, label=Ulster Scots dialect, Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is #Descriptions, variously described as .... The series is a major contribution to plant conservation in Great Britain, and, as such, covers material appropriate for professionals and amateurs interested in the conservation of native plant communities. Each book begins with an introduction to the techniques used to survey the particular vegetations within its scope, discussing sampling, the type of data collected, organizati ...

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sagina Procumbens
''Sagina procumbens'' is a species of flowering plant. in the family Caryophyllaceae known by the common names procumbent pearlwort, birdeye pearlwort and matted pearlwort. It can be found throughout the Northern Hemisphere and parts of South America. It is a common weed of many environments. It can be found in wild and disturbed habitat, especially moist areas. It can sometimes be seen growing in lawns or in cracks in pavements. This is a perennial herb forming clumps or mats of hairless green herbage, sometimes vaguely resembling a patch of moss. The leaves are linear and up to 1 or 2 centimeters long. The inflorescence is a solitary flower with four or five sepals and four or five small white petals, but the petals are sometimes absent. Description Showing short leaves no more than 10mm long. Flowers minute and solitary, sepals 4 or 5, petals minute or absent. As an invasive species In 1998 numerous well-developed plants were found on the UNESCO World Heritage Site of Gough ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytosociology
Phytosociology, also known as phytocoenology or simply plant sociology, is the study of groups of species of plant that are usually found together. Phytosociology aims to empirically describe the vegetative environment of a given territory. A specific community of plants is considered a social unit, the product of definite conditions, present and past, and can exist only when such conditions are met. In phyto-sociology, such a unit is known as a phytocoenosis (or phytocoenose). A phytocoenosis is more commonly known as a plant community, and consists of the sum of all plants in a given area. It is a subset of a biocoenosis, which consists of all organisms in a given area. More strictly speaking, a phytocoenosis is a set of plants in area that are interacting with each other through competition or other ecological processes. Coenoses are not equivalent to ecosystems, which consist of organisms and the physical environment that they interact with. A phytocoensis has a distribution wh ...
