Vegetation Of Open Habitats In The British National Vegetation Classification System
This article gives an overview of the plant communities formed by vegetation of open habitats in the British National Vegetation Classification system. Introduction The open habitat communities of the NVC were described in Volume 5 of ''British Plant Communities'', first published in 2000, along with the three groups of maritime communities ( shingle, strandline and sand-dune communities, salt-marsh communities and maritime cliff communities). In total, 42 open habitat communities have been identified. The open habitat communities consist of eight distinct subgroups: * six arable weed and trackside communities of light, less-fertile acid soils ( OV1, OV2, OV3, OV4, OV5 and OV6) * eight arable weed and wasteland communities of fertile loams and clays (OV7 OV7, formerly known as La Onda Vaselina, is a Mexican Latin pop group formed in 1989, but it was not until the early 1990s that Onda Vaselina would begin to make their impact. La Onda Vaselina was formed with the membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'' ...

Capsella Bursa-pastoris
''Capsella bursa-pastoris'', known as shepherd's purse because of its triangular flat fruits, which are purse-like, is a small annual and ruderal flowering plant in the mustard family (Brassicaceae). It is native to eastern Europe and Asia minor, but is naturalized and considered a common weed in many parts of the world, especially in colder climates, including British Isles, where it is regarded as an archaeophyte,Preston CD, Pearman DA & Dines TD (2002) New Atlas of the British Flora. Oxford University Press North America and China, but also in the Mediterranean and North Africa. ''C. bursa-pastoris'' is the second-most prolific wild plant in the world, and is common on cultivated ground and waysides and meadows. Scientists have referred to this species as a 'protocarnivore', since it has been found that its seeds attract and kill nematodes as a means to locally enrich the soil. History Pictured and published in 1486. Description ''Capsella bursa-pastoris'' plants grow from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chenopodium Album
''Chenopodium album'' is a fast-growing weedy annual plant in the genus ''Chenopodium''. Though cultivated in some regions, the plant is elsewhere considered a weed. Common names include lamb's quarters, melde, goosefoot, wild spinach and fat-hen, though the latter two are also applied to other species of the genus ''Chenopodium'', for which reason it is often distinguished as white goosefoot.BSBIDatabase of names (xls file) ''Chenopodium album'' is extensively cultivated and consumed in Northern India, Nepal, and Pakistan as a food crop known as ''bathua''.

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senecio Vulgaris
''Senecio vulgaris'', often known by the common names groundsel and old-man-in-the-spring, is a flowering plant in the family Asteraceae. It is an annual herb, native to Europe and widely naturalised as a ruderal species in suitable disturbed habitats worldwide. Description ''Senecio vulgaris'' is an erect herbaceous annual growing up to 16 inches (45 cm) tall. The inflorescences usually lack ray florets, the yellow disc florets mostly hidden by the bracts giving the flowers an inconspicuous appearance. ''Senecio vulgaris'' is very similar to ''Senecio viscosus'' but ''S. vulgaris'' does not have the glandular hairs and ray florets found in ''S. viscosus''. Leaves and stems Upper leaves of ''Senecio vulgaris'' are sessile, lacking their own stem ( petiole), alternating in direction along the length of the plant, two rounded lobes at the base of the stem ( auriculate) and sub-clasping above. Leaves are pinnately lobed and + long and wide, smaller towards the top of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellaria Media
''Stellaria media'', chickweed, is an annual and perennial flowering plant in the family Caryophyllaceae.Fernald, M. L. 1950. “Gray's Manual of Botany”. Eight Edition. American Book Company, New York, NY. 1632 pp. It is native to Eurasia and naturalized throughout the world. This species is used as a cooling herbal remedy, and grown as a vegetable crop and ground cover for both human and poultry consumption. It is sometimes called common chickweed to distinguish it from other plants called chickweed. Other common names include chickenwort, craches, maruns, and winterweed. The plant germinates in autumn or late winter, then forms large mats of foliage. Description This species is an annual in colder climates, becoming evergreen and perennial in warmer zones, with weak slender stems, up to . Plants are sparsely hairy. ''Stellaria media'' has one line of fine hairs on the stem. The leaves are oval and opposite, the lower ones with stalks. Flowers are white and small with ...

Urtica Urens
''Urtica urens'', commonly known as annual nettle, dwarf nettle, small nettle, dog nettle, or burning nettle, is a herbaceous annual flowering plant species in the nettle family Urticaceae. It is native to Eurasia, including the Himalayan regions of Kalimpong, Darjeeling and Sikkim in India and can be found in North America, New Zealand and South Africa as an introduced species. It is reputed to sting more strongly than common nettle. Description Unlike the perennial and dioecious stinging nettle ''Urtica dioica'', ''Urtica urens'' is an annual plant, monoecious (with male and female flowers on the same plant) and generally much shorter. It can be distinguished from the stinging nettle by its more rounded leaves with coarser, deeper toothing and with the terminal tooth of similar length to the adjacent teeth. The lower leaves are shorter than their longer petioles and have stinging hairs only. Distribution The native distribution of ''Urtica urens'' includes most of Europe except ...

Erodium Moschatum
''Erodium moschatum'' is a species of flowering plant in the Geraniaceae, geranium family known by the common names musk stork's-bill and whitestem filaree. This is a weedy annual or biennial herb which is native to much of Eurasia and North Africa but can be found on most continents where it is an introduced species. Description Musk stork's-bill is an annual Monoecy, monoecious herb which grows as a sprawling, procumbent to erect plant up to about 60 cm long or tall, with a musky smell when bruised. It is almost entirely covered with either simple or sticky glandular hairs except for the fruits and petals. The stems are green to purple in colour and bear alternate or opposite pinnate leaves up to about 10 cm long (up to 30 cm in very large plants). The leaf segments are serrated and lobed, but not deeply so: no more than about a quarter of the way to the midrib. The petioles are somewhat shorter than the blade, and have papery stipules up to 10 mm long at their base. The inflo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicago Polymorpha
''Medicago polymorpha'' is a plant species of the genus ''Medicago''. It is native to the Mediterranean basin but is found throughout the world. It forms a symbiotic relationship with the bacterium ''Sinorhizobium medicae'', which is capable of nitrogen fixation. Common names include California burclover, toothed bur clover, toothed medick and burr medic. Description This weedy forb is an Annual plant, annual Flowering plant, broadleaf plant. It inhabits agricultural land, roadsides and other disturbed areas. It is found in lawns as well, where its burrs are able to cling to the clothing or fur of any species that pass near it, thus facilitating geographic spread via these seed capsules. It makes a poor lawn in the late summer, when the leaves have yellowed and fruit sets into the 7 mm seed heads that are covered with hooked prickles. Burclover is a good forage for livestock, but the fruit is prickly. All classes of livestock, except horses and mules, can feed its lea ...

Sisymbrium Irio
''Sisymbrium irio'', the London rocket, is a plant in the family Brassicaceae. It is an annual herb exceeding three feet in height with open, slender stem branches. The flowers are small with four pale yellow petals. The basal leaves are broad and often lobed, while the upper leaves are linear in shape and up to four inches long. The fruit is a long narrow cylindrical silique which stays green when ripe. The younger pods overtop the flowers. When dried the fruit has small red oblong seeds. The term "London" in the common name "London rocket" allegedly comes from its abundance after the Great Fire of London in 1666. Plants and seed must have been present in London prior to the fire but generally overlooked until their abundant appearance after the fire; Robert Morison, the physician to King Charles II, attributed their appearance to spontaneous generation when he observed that “these hot bitter plants with four petals and pods were produced spontaneously without seed by the ash ...
