British NVC Community OV17
British NVC community OV17 (''Reseda lutea'' - ''Polygonum aviculare'' community) is one of the open habitat communities in the British National Vegetation Classification system. Although classed with communities OV15 and OV16 as an arable weed community of light lime-rich soils, it also shares many features with the communities classed as arable weed and wasteland communities of fertile loams and clays. This community is not found elsewhere in Europe, and in Britain is found only in East Anglia. It was first described by Silverside (1977), who labelled it the ''Descurainio''-''Anchusetum arvensis'' association. There are no subcommunities. Community composition The following constant species are found in this community: * Bugloss ('' Anchusa arvensis'') * Black-bindweed (''Fallopia convolvulus ''Fallopia convolvulus'', the black-bindweed or wild buckwheat, is a fast-growing annual flowering plant in the family Polygonaceae native throughout Europe, Asia and northern A ...

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 NVC Community OV15
British NVC community OV15 (''Anagallis arvensis'' - ''Veronica persica'' community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of two arable weed communities of light lime-rich soils.

East Anglia
East Anglia is an area in the East of England, often defined as including the counties of Norfolk, Suffolk and Cambridgeshire. The name derives from the Anglo-Saxon kingdom of the East Angles, a people whose name originated in Anglia, in what is now Northern Germany. Area Definitions of what constitutes East Anglia vary. The Anglo-Saxon Kingdom of East Anglia, established in the 6th century, originally consisted of the modern counties of Norfolk and Suffolk and expanded west into at least part of Cambridgeshire, typically the northernmost parts known as The Fens. The modern NUTS 3 statistical unit of East Anglia comprises Norfolk, Suffolk and Cambridgeshire (including the City of Peterborough unitary authority). Those three counties have formed the Roman Catholic Diocese of East Anglia since 1976, and were the subject of a possible government devolution package in 2016. Essex has sometimes been included in definitions of East Anglia, including by the London Society o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anchusa Arvensis
''Anchusa arvensis'' is a plant species of the genus ''Anchusa''. Its common names include small bugloss and annual bugloss. Description This is a hairy annual herb which may reach half a meter in height. It bears small blue tubular flowers, four nutlets per flower, and one seed per nutlet. Leaves are very bristly and warty-looking, which differentiates it from similar species like '' Pentaglottis sempervirens'' and ''Myosotis arvensis''. Distribution and Habitat The plant is native to Europe, and is found elsewhere. ''Anchusa arvensis'' is found in arable field margins, sandy heaths A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler a ..., disturbed ground. In the UK it is a declining species with patchy distribution, however conservation status as of 2005 is least concern. ''Anc ...

Chenopodium Album
''Chenopodium album'' is a fast-growing weedy annual plant in the genus ''Chenopodium''. Though cultivated in some regions, the plant is elsewhere considered a weed. Common names include lamb's quarters, melde, goosefoot, wild spinach and fat-hen, though the latter two are also applied to other species of the genus ''Chenopodium'', for which reason it is often distinguished as white goosefoot.BSBIDatabase of names (xls file) ''Chenopodium album'' is extensively cultivated and consumed in Northern India, Nepal, and Pakistan as a food crop known as ''bathua''.

Descurainia Sophia
''Descurainia sophia'' is a member of the family Brassicaceae. Common names include flixweed, herb-Sophia and tansy mustard. It reproduces by seeds. It is a dominant weed in dark brown prairie and black prairie soils of southern Alberta. Its stem is erect, branched, and high. It was once given to patients with dysentery and called by ancient herbalists ''Sophia Chirurgorum'', "The Wisdom of Surgeons". It is the type species of the genus ''Descurainia'' (named for French botanist and herbalist François Descurain (1658–1749)) and of the rejected genus ''Sophia'' Adans. Culinary use In Iran, the seeds are called ''khak-e shir'' (''khakshir''), and khak-e shir drinks are traditionally favored as thirst quencher during hot summer days. Khakshir is also considered a medicinal substance in traditional Iranian medicine, consumed in varying combinations with other herbs and substances to gain effects ranging from antidiuretic to aphrodisiac.

Polygonum Aviculare
''Polygonum aviculare'' or common knotgrass is a plant related to buckwheat and dock. It is also called prostrate knotweed, birdweed, pigweed and lowgrass. It is an annual found in fields and wasteland, with white flowers from June to October. It is widespread across many countries in temperate regions, apparently native to Eurasia, naturalized in temperate parts of the Southern Hemisphere. Description Common knotgrass is an annual herb with a semi-erect stem that may grow from high. The leaves are hairless and short-stalked. They are longish-elliptical with short stalks and rounded bases; the upper ones are few and are linear and stalkless. The stipules are fused into a stem-enclosing, translucent sheath known as an ochrea that is membranous and silvery. The flowers are regular, green with white or pink margins. Each has five perianth segments, overlapping at the base, five to eight stamens and three fused carpels. The fruit is a dark brown, three-edged nut. The seeds need l ...
