British NVC Community A9
__NOTOC__ The ''Potamogeton natans'' community (NVC community A9) is one of the aquatic communities in the British National Vegetation Classification system. It is a comparatively widely distributed community. There are three subcommunities. Community composition One constant species is found in this community, Broad-leaved Pondweed (''Potamogeton natans''). No rare species are associated with the community. Distribution This community is found widely throughout Britain Britain most often refers to: * The United Kingdom, a sovereign state in Europe comprising the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands * Great Britain, the largest island in the United King .... Subcommunities There are three subcommunities: * the so-called Species-poor subcommunity * the ''Elodea canadensis'' subcommunity * the ''Juncus bulbosus - Myriophyllum alterniflorum'' subcommunity References * Rodwell, J. S. (1995) '' British Plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Communities In The British National Vegetation Classification System
This article gives an overview of the aquatic communities in the British National Vegetation Classification system. Introduction The aquatic communities of the NVC were described in Volume 4 of ''British Plant Communities'', first published in 1995, along with the swamps and tall-herb fens. In total, 24 aquatic communities have been identified. The aquatic communities fall into the following six groups: * four communities of the water surface and sub-surface, in which duckweeds and/or Frogbit are the constant species; these communities ( A1, A2, A3 and A4) are found in moderately-rich to eutrophic standing waters * eight free-floating or rooted and submerged, pondweed communities ( A5, A6, A11, A12, A13, A14, A15 and A21) * six communities in which rooted water-lilies and pondweeds with floating leaves are the constant species ( A7, A8, A9, A10, A19 and A20) * three communities in which water-crowfoots and/or starworts are the constant species ( A16, A17 and A ...

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'' ...

Potamogeton Natans
''Potamogeton natans'', commonly known as broad-leaved pondweed, floating pondweed, or floating-leaf pondweed, is an aquatic species in the genus ''Potamogeton'' native to quiet or slow-flowing freshwater habitats throughout the Holarctic Kingdom. Description It produces both floating and submersed leaves on the same plant. The floating leaves are ovate to oblong-ovate and almost always cordate at the base. They are dark green, leathery, opaque, with translucent longitudinal veins. They are 5 to 10 cm long, pointed at the tips, and rounded at the base. The stipules are 4 to 17 cm long. The submerged grass-like structures are called phyllodes, are actually modified leaf stalks. The stems are cylindrical, without many branches, and grow from 1 to 2 metres. The main difference between this species and other pondweeds is a discoloured flexible joint just below the top of the long leaf stalk. The flower spikes are dense, and cylindrical. They are 5 to 10 cm lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

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 ...
