British NVC Community CG4
__NOTOC__ NVC community CG4 (''Brachypodium pinnatum'' grassland) is one of the calcicolous grassland communities in the British National Vegetation Classification system. It is one of four communities of rank, tussocky grassland associated with low levels of grazing, within the lowland calcicolous grassland group. It is a comparatively widely distributed community. There are three subcommunities. Community composition The following constant species are found in this community: * Tor-grass (''Brachypodium pinnatum'') * Glaucous Sedge (''Carex flacca'') * Sheep's Fescue (''Festuca ovina'') The following rare species are also associated with the community: * Purple Milk-vetch (''Astragalus danicus'') * Musk Orchid (''Herminium monorchis'') Distribution This community is found in lowland limestone grassland throughout England. Subcommunities There are three subcommunities: * the so-called typical subcommunity: * the ''Avenula pratensis - Thymus praecox'' subcommunity * ...

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'' ...

Tor-grass
''Brachypodium pinnatum'', the heath false brome or tor-grass, is a species of grass with a widespread distribution in temperate regions of the Northern Hemisphere. It typically grows in calcareous grassland, and reaches tall. The flowerhead is open, with 10 to 15 erect spikelets. Distribution The plant can be found in such US states as California, Massachusetts, and Oregon. Ecology The caterpillars of some Lepidoptera use it as a food plant, e.g. the Essex skipper (''Thymelicus lineola''). It is also one of the most important host grasses for Auchenorrhyncha in central Europe.Nickel, H. (2003).

Sheep's Fescue
''Festuca ovina'', sheep's fescue or sheep fescue, is a species of grass. It is sometimes confused with hard fescue (''Festuca trachyphylla''). General description It is a perennial plant sometimes found in acidic ground, and in mountain pasture, throughout Europe (with the exception of some Mediterranean areas) and eastwards across much of Asia; it has also been introduced to North America. It is one of the defining species of the British NVC community CG2, i.e. ''Festuca ovina'' – ''Avenula pratensis'' grassland, one of the calcicolous grassland communities. However, the species has a wide ecological tolerance in the UK, occurring on both basic and acid soils, as well as old mining sites and spoil heaps that are contaminated with heavy metals. Sheep's fescue is a densely tufted perennial grass. Its greyish-green leaves are short and bristle-like. The panicles are both slightly feathery and a bit one-sided. It flowers from May until June, and is wind-pollinated. It has no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limestone Grassland
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limestone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

British Plant Communities (series Of Books)
''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, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Nort .... 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 ...
