British NVC Community SD17
NVC community SD17 (''Potentilla anserina - Carex nigra'' dune-slack community) is one of the 16 sand-dune communities in the British National Vegetation Classification system. It is one of five communities associated with dune slacks. It is a very localised community. There are four subcommunities. Community composition The following constant species are found in this community: * Creeping Bent (''Agrostis stolonifera'') * Common Sedge (''Carex nigra'') * Silverweed (''Potentilla anserina'') * Pointed Spear-moss (''Calliergon cuspidatum'') No rare species are associated with the community. Distribution This community is found in two areas - on the east coast, from Spurn Point to northwest Norfolk, and on the dunes of Liverpool Bay Liverpool Bay is a bay of the Irish Sea between northeast Wales, Cheshire, Lancashire and Merseyside to the east of the Irish Sea. The bay is a classic example of a region of freshwater influence. Liverpool Bay has historically suffered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shingle, Strandline And Sand-dune Communities In The British National Vegetation Classification System
This article gives an overview of the shingle, strandline and sand-dune communities in the British National Vegetation Classification system. Introduction The shingle, strandline and sand-dune communities of the NVC were described in Volume 5 of ''British Plant Communities'', first published in 2000, along with the other maritime communities (those of saltmarshes and maritime cliffs) and vegetation of open habitats. In total, 19 shingle, strandline and sand-dune communities have been identified. The shingle, strandline and sand-dune communities consist of a single community found on coastal shingle ( SD1), two communities associated with strandlines ( SD2 and SD3), and sixteen sand-dune communities. The sand-dune communities fall into the following four groups: * six foredune and mobile dune communities ( SD4, SD5, SD6, SD7, SD10 and SD19) * four fixed-dune grasslands ( SD8, SD9, SD11 and SD12) * five dune-slack communities ( SD13, SD14, SD15, SD16 and SD17) * o ...

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'' ...

Agrostis Stolonifera
''Agrostis stolonifera'' (creeping bentgrass, creeping bent, fiorin, spreading bent or carpet bentgrass) is a perennial grass species in the family Poaceae. Description ''Agrostis stolonifera'' is stoloniferous and may form mats or tufts. The prostrate stems of this species grow to long with long leaf blades and a panicle reaching up to in height. The ligule is pointed and up to long. This differs from common bent, ''Agrostis capillaris'', which is short and does not come to a point. The leaves are tapering, often with a blue-grey colour. The grass is not tufted and the spikelets are red and tightly closed within the panicle. It flowers in July and August. Distribution It can be found growing in a variety of habitats including woodlands, grasslands and meadows, wetlands, riparian zones, and as a pioneer species on disturbed sites. It is native to Eurasia and North Africa (Algeria, Morocco and Tunisia). It is possible that it may also be native to northern parts of ...

Common Sedge
''Carex nigra'' is a perennial species of plants in the family Cyperaceae native to wetlands of Europe, western Asia, northwestern Africa, and eastern North America. Common names include common sedge, black sedge or smooth black sedge. The eastern limit of its range reaches central Siberia, Turkey and probably the Caucasus.

Spurn Point
Spurn is a narrow sand tidal island located off the tip of the coast of the East Riding of Yorkshire, England that reaches into the North Sea and forms the north bank of the mouth of the Humber Estuary. It was a spit with a semi-permanent connection to the mainland, but a storm in 2013 made the road down to the end of Spurn impassable to vehicles at high tide. The island is over long, almost half the width of the estuary at that point, and as little as wide in places. The southernmost tip is known as Spurn Head or Spurn Point and is the home to an RNLI lifeboat station and two disused lighthouses. It forms part of the civil parish of Easington. Spurn Head covers above high water and of foreshore. It has been owned since 1960 by the Yorkshire Wildlife Trust and is a designated national nature reserve, heritage coast and is part of the Humber Flats, Marshes and Coast Special Protection Area. History Spurn Head was known to classical authors, such as Ptolemy as ''Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk
Norfolk () is a ceremonial and non-metropolitan county in East Anglia in England. It borders Lincolnshire to the north-west, Cambridgeshire to the west and south-west, and Suffolk to the south. Its northern and eastern boundaries are the North Sea, with The Wash to the north-west. The county town is the city of Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km2). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000). The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is protected by the Broads Authority and has similar status to a national park. History The area that was to become Norfolk was settled in pre-Roman times, (there were Palaeolithic settlers as early as 950,000 years ago) with camps along the highe ...

Liverpool Bay
Liverpool Bay is a bay of the Irish Sea between northeast Wales, Cheshire, Lancashire and Merseyside to the east of the Irish Sea. The bay is a classic example of a region of freshwater influence. Liverpool Bay has historically suffered from reduced oxygen content from prior massive discharges of sewage sludge, according to C. Michael Hogan. The rivers Alt, Clwyd, Dee, Ribble and Mersey drain into the bay. The bay is littered with wrecks and has many dive sites. The bay also contains several oil and gas fields including the Douglas Complex, with a combined daily capacity (January 2008) of 60,000 barrels. The UK's first major offshore wind farm, North Hoyle, is located in the south of the bay, which is a busy shipping route to the Mersey Docks. The land area around the bay is occasionally referred to as the "Liverpool Bay Area". Though the term is seen by some as a possible official alternative to Merseyside, it is more often used to describe a much wider area which may ...

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.
