Arrhenatheretum Elatioris
__NOTOC__ British NVC community MG1, ''Arrhenatherum elatius'' grassland, is one of the mesotrophic grassland communities in the British National Vegetation Classification system. This type of plant community was named in 1919 as Arrhenatheretum elatioris Br.-Bl.. It is a very widespread community throughout the British lowlands of England, Wales and southern and eastern Scotland. The following constant species are found in this community: * False Oat-grass (''Arrhenatherum elatius'') * Cock's-foot (''Dactylis glomerata'') One rare species, Nottingham Catchfly (''Silene nutans''), is associated with this community. Subcommunities There are five subcommunities, and two of these have been further subdivided into a number of variants Variant may refer to: In arts and entertainment * ''Variant'' (magazine), a former British cultural magazine * Variant cover, an issue of comic books with varying cover art * ''Variant'' (novel), a novel by Robison Wells * "The Variant", 202 ...

Arrhenatherum Elatius
''Arrhenatherum elatius'', with the common names bulbous oat grass, false oat-grass, tall oat-grass, tall meadow oat, onion couch and tuber oat-grass, is a species of perennial grass, native to Europe, western Asia, and northern Africa. This bunchgrass is often used as an ornamental grass and is sometimes marketed as " cat grass". It is native to Europe but can be found elsewhere as an introduced species. It is found especially in prairies, at the side of roads and in uncultivated fields. The bulbous subspecies can be a weed of arable land. It is palatable grass for livestock and is used both as forage (pasture) and fodder ( hay and silage). Description This coarse grass can grow to tall. The leaves are bright green, broad, slightly hairy, and rough. The ligule is long and smooth edged. The panicle A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush ( Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesotrophic Grasslands In The British National Vegetation Classification System
The mesotrophic grassland communities in the British National Vegetation Classification system were described in Volume 3 of '' British Plant Communities'', first published in 1992, along with the calcicolous grassland communities and the calcifugous grasslands and montane communities. In total, 13 mesotrophic grassland communities have been identified: * two communities in which False Oat-grass is the characteristic grass species (one of these, community MG1, is widespread throughout Britain; the other, MG2, is confined to northern England England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe ...). * four communities of well-drained permanent pastures and meadows, two of which ( MG5 and MG6) are widespread and the other two ( MG3 and MG4) more localised * a single community ( MG ...

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 ...

Plant Community
A plant community is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance. In many cases there are several soil types present within a given plant community. This is because the soil type within an area is influenced by two factors, the rate at which water infiltrates or exits (via evapotranspiration) the soil, as well as the rate at which organic matter (any carbon-based compound within the environment, such as decaying plant matter) enters or decays from the soil. Plant communities are studied substantially by ecologists, due to providing information on the effects of dispersal, tolerance to environmental conditions, and response to disturbance of a variety of plant species, information valuable to the comprehension of various pla ...

Tees–Exe Line
The Tees–Exe line is an imaginary northeast-southwest line that can be drawn on a map of Great Britain which roughly divides the island into lowland and upland regions. The line links the mouth of the River Tees between Redcar and Hartlepool in the north east of England with the mouth of the River Exe in Devon in the south west. To the south and east of this line, the landscape, whilst not always flat, is certainly lower and is characterised by flat-lying or gently tilted or folded sedimentary rocks. North and west of this line are the older, generally harder rocks including igneous and metamorphic rocks and the Palaeozoic and Precambrian sandstones and limestones which usually stand out as upland areas.Monkhouse, F.J. 1971 ''Principles of Physical Geography'' University of London Press, London The areas to the north and west of the line also have a generally wetter climate than areas to the east and south. Other imaginary lines can be drawn, for similar purposes, between the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scottish Lowlands
The Lowlands ( sco, Lallans or ; gd, a' Ghalldachd, , place of the foreigners, ) is a cultural and historical region of Scotland. Culturally, the Lowlands and the Highlands diverged from the Late Middle Ages into the modern period, when Lowland Scots replaced Scottish Gaelic throughout most of the Lowlands. Geography The Lowlands is not an official geographical or administrative area of the country. There are two main topographic regions: the Lowlands and the Southern Uplands. The term "Lowlands" mainly refers to the Central Lowlands. However, in normal usage it refers to those parts of Scotland not in the Highlands (or Gàidhealtachd). The boundary is usually considered to be a line between Stonehaven and Helensburgh (on the Firth of Clyde). The Lowlands lie south and east of the line. Note that some parts of the Lowlands (such as the Southern Uplands) are not physically "low," Merrick for example reaching , while some areas indisputably in the Highlands (such a ...

Cock's-foot
''Dactylis'' is a genus of Eurasian and North African plants in the bluegrass subfamily within the grass family. ''Dactylis'' is native to North Africa, they are found throughout the world, and are an invasive species. They are known in English as cock's-foot or cocksfoot grasses, also sometimes as orchard grasses. Taxonomy The genus has been treated as containing only a single species '' Dactylis glomerata'' by many authors, treating variation in the genus at only subspecific rank within ''D. glomerata'',Flora Europaea''Dactylis glomerata''Flora of China Town''Dactylis''/ref> but more recently, there has been a trend to accept two species,Germplasm Resources Information NetworkSpecies Records of ''Dactylis'' while some authors accept even more species in the genus, particularly island endemic species in Macaronesia.Schönfelder, P., & Ludwig, D.

Nottingham Catchfly
''Silene nutans'' is a flowering plant in the genus ''Silene'', most commonly known as Nottingham catchfly. Description ''Silene nutans'' is a diploid, mainly outcrossing, herbaceous, perennial plant. It grows up to tall, from a branching, woody stock with a thick taproot. The lower leaves are up to long, spathulate and have a long stalk, while leaves higher on the plant are lanceolate, subsessile and acute; all the leaves are covered in soft hairs. The flowers are wide, long, and drooping, on short, viscid stalks. The petals are white or pinkish and divided into two narrow lobes. Each flower remains open for three nights as a means of preventing self-fertilisation; the flower reveals one whorl of stamens on the first night, the second whorl of stamens on the second night, and the three styles on the third night. The seeds are wide and kidney-shaped. Distribution ''Silene nutans'' is widespread across Europe, from southern Spain and Italy north to the British Isles and S ...
