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'' ...

Nature
Nature, in the broadest sense, is the physics, physical world or universe. "Nature" can refer to the phenomenon, phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word ...

Vascular Plant
Vascular plants (), also called tracheophytes () or collectively Tracheophyta (), form a large group of land plants ( accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants", as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcifugous Grasslands And Montane Communities In The British National Vegetation Classification System
Calcifugous grasslands and montane communities are botanical groupings in the British National Vegetation Classification system. The calcifugous grasslands and montane communities of the NVC were described in Volume 3 of ''British Plant Communities'', first published in 1992, along with the mesotrophic grassland communities and the calcicolous grassland communities. In total, 21 calcifugous grasslands and montane communities have been identified. The calcifugous grasslands and montane communities consist of the following groupings: * five grass-dominated communities which group together as "sub-montane calcifugous grasslands"; two of these, U1 and U2 are found throughout Britain, two more U4 and U5 are found throughout upland areas of Scotland, Wales and northern and western England, and one, U3, is localised in southwest England. * a sixth submontane community, U6, dominated by Heath Rush ''Juncus squarrosus'' * four communities categorised as "calcifugous vegetation ...

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). * 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 ( MG7) covering a variety of widespread types of Perennial Rye-grass long-term ley * three widespread communities associated with poorly drained permanent pastures ( MG8, MG9, MG10) * three grass-dominated inundation communities, one of which, MG13 The MG 13 (sh ...

Heaths In The British National Vegetation Classification System
This article gives an overview of the heath communities in the British National Vegetation Classification system. Introduction The heath communities of the NVC were described, along with the mire communities, in Volume 2 of ''British Plant Communities'', first published in 1991. In total, 22 heath communities have been identified. The heath communities consist of six separate subgroups: * five lowland dry heath communities, all with distinct, largely non-overlapping distributions in England and Wales ( H1, H2, H6, H8 and H9) * three localised communities, with non-overlapping ranges in southern England, which are considered transitional between the above and the wetter communities classified in the NVC as mires ( H3, H4 and H5) * two maritime heath communities, found exclusively on the coasts of northern and western Britain; one ( H7) is more widespread than the other ( H11) * four submontane heaths from upland areas in northern and western Britain; two of these ( H10 and ...

Mires In The British National Vegetation Classification System
This article gives an overview of the mire plant communities in the British National Vegetation Classification system. Introduction The mire communities of the NVC were described in Volume 2 of ''British Plant Communities'', first published in 1991, along with the heath communities.

Vice-county
A vice-county (vice county or biological vice-county) is a geographical division of the British Isles used for the purposes of biological recording and other scientific data-gathering. It is sometimes called a Watsonian vice-county as vice-counties were introduced for Great Britain, its offshore islands, and the Isle of Man, by Hewett Cottrell Watson who first used them in the third volume of his ''Cybele Britannica'' published in 1852. Watson's vice-counties were based on the ancient counties of Britain, but often subdividing these boundaries to create smaller, more uniform units, and considering exclaves to be part of the surrounding vice-county. In 1901 Robert Lloyd Praeger introduced a similar system for Ireland and its off-shore islands. Vice-counties are the "standard geographical area for county based ..recording". They provide a stable basis for recording using similarly sized units, and, although National Grid-based reporting has grown in popularity, vice-counties ...

Bryophyte
The Bryophyta s.l. are a proposed taxonomic division containing three groups of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. Bryophyta s.s. consists of the mosses only. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. The bryophytes consist of about 20,000 plant species. Bryophytes produce enclosed reproductive structures (gametangia and sporangia), but they do not produce flowers or seeds. They reproduce sexually by spores and asexually by fragmentation or the production of gemmae. Though bryophytes were considered a paraphyletic group in recent years, almost all of the most recent phylogenetic evidence supports the monophyly of this group, as originally classified by Wilhelm Schimper in 1879. The term ''bryophyte'' comes . Terminology The term "Bryophyta" was first suggested by Braun in 1864. G.M. Smith placed this group between Algae and Pteridophyta. Features The d ...
