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 ...

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'' ...

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. In total, 38 mire communities have been identified. The mire communities consist of a number of separate subgroups. * five bog plane communities ( M17, M18, M19, M20 and M21) * two wet heath communities ( M15 and M16) * four bog-pool communities ( M1, M2, M3 and M4) * four base-poor small sedge & rush communities ( M5, M6, M7 and M8) * six base-poor small sedge & ''Schoenus'' communities ( M9, M10, M11, M12, M13 and M14) * seven fen-meadow A fen-meadow is a type of peatland, common in North America and Europe, that receives water from precipitation and groundwater.

Bristle Bent
''Agrostis curtisii'', the bristle bent, is a species of grass in the family Poaceae native to Eurasia. It is densely tufted, with hair like leaves and stems that grow up to 60 cm. Its spikelets are yellow-green in colour, and its lemmas are awned. The ligule is pointed. It has no rhizomes or stolons. Bristle bent flowers in the UK from June until July and is found typically on dry heaths and moors The term Moor, derived from the ancient Mauri, is an exonym first used by Christian Europeans to designate the Muslim inhabitants of the Maghreb, the Iberian Peninsula, Sicily and Malta during the Middle Ages.

Calluna
''Calluna vulgaris'', common heather, ling, or simply heather, is the sole species in the genus ''Calluna'' in the flowering plant family Ericaceae. It is a low-growing evergreen shrub growing to tall, or rarely to and taller, and is found widely in Europe and Asia Minor on acidic soils in open sunny situations and in moderate shade. It is the dominant plant in most heathland and moorland in Europe, and in some bog vegetation and acidic pine and oak woodland. It is tolerant of grazing and regenerates following occasional burning, and is often managed in nature reserves and grouse moors by sheep or cattle grazing, and also by light burning. ''Calluna'' was separated from the closely related genus ''Erica'' by Richard Anthony Salisbury, who devised the generic name ''Calluna'' probably from the Ancient Greek (), "beautify, sweep clean", in reference to its traditional use in besoms. The specific epithet ''vulgaris'' is Latin for 'common'. ''Calluna'' is differentiated from ''Er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell Heather
''Erica cinerea'', the bell heather, is a species of flowering plant in the heath family Ericaceae, native to western and central Europe. The plant provides a great deal of nectar for pollinators. It was rated in the top 5 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Description It is a low, spreading shrub growing to tall, with fine needle-like leaves long arranged in whorls of three. The flowers are bell-shaped, purple (rarely white), long, produced in mid- to late summer. The flowers are dry, similar in texture to the strawflower. The Latin specific epithet ''cinerea'' means "ash coloured". Distribution ''Erica cinerea'' is native to the west of Europe, where it is most abundant in Britain and Ireland, France, northern Spain and southern Norway. It also occurs in the Faroe Islands, Belgium, Germany, north-western Italy, and the Netherlands. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-leaved Heath
''Erica tetralix'', the cross-leaved heath, is a species of flowering plant in the family Ericaceae, native to western Europe, from southern Portugal to central Norway, as well as a number of boggy regions further from the coast in Central Europe such as Austria and Switzerland. In bogs, wet heaths and damp coniferous woodland, ''E. tetralix'' can become a dominant part of the flora. It has also been introduced to parts of North America. Description It is a perennial subshrub with small pink bell-shaped drooping flowers borne in compact clusters at the ends of its shoots, and leaves in whorls of four (whence the name). The flowers appear in summer and autumn. The distinction between ''E. tetralix'' and the related species ''Erica cinerea'' is that the linear leaves are usually glandular and in whorls of four, while those of ''Erica cinerea'' are glabrous and borne in whorls of three. The leaves of ''Calluna vulgaris'' are much smaller and scale-like and borne in opposite and dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple Moor-grass
''Molinia caerulea'', known by the common name purple moor-grass, is a species of grass that is native to Europe, west Asia, and north Africa. It grows in locations from the lowlands up to in the Alps. Like most grasses, it grows best in acid soils, ideally pH values of between 3.5 and 5, however, it can continue to live under more extreme conditions, sometimes to as low as 2. It is common on moist heathland, bogs and moorland throughout Britain and Ireland. Introduced populations exist in northeastern and northwestern North America. The specific epithet ''caerulea'' means "deep blue" and refers to the purple spikelets. Description ''Molinia caerulea'' is a herbaceous perennial bunchgrass (tussock-forming), growing up to tall (taller when sheltered by gorse and heather), with many closely packed stems. The leaves are coarse, green, taper to a point, long, flat and sometimes slightly hairy on top. Due to the dense tussock it is very resistant to heath fires. Its ligule ...

Dwarf Gorse
''Ulex minor'', the dwarf furze or dwarf gorse is an evergreen dwarf shrub in the family Fabaceae, native to eastern England, France, Spain and Portugal. It is restricted to lowland heathland habitats. It normally grows about tall, although in shaded, un grazed conditions it may reach . It is a low-growing shrub, forming small bushes or often growing mingled with heather. The leaves are limited to scales or small spines, and the shoots are modified into rather soft, green, densely crowded spines, about long. The flowers are yellow, long, with the typical pea-flower structure; they are produced principally in the late summer and autumn, rarely before July. The fruit is a legume (pod), partly enclosed by the pale brown remnants of the flower. Due to its relatively soft spines, dwarf furze is readily grazed by livestock and wild herbivores. The distributions of dwarf furze and its close relative western gorse (''Ulex gallii ''Ulex gallii'', the western gorse or dwar ...

Dorset Heath
''Erica ciliaris'' is a species of heather, known in the British Isles as Dorset heath. It grows to , and has leaves long, with long, glandular hairs. The flowers are long, bright pink, and arranged in long racemes. Distribution ''Erica ciliaris'' has a Lusitanian distribution, stretching from Morocco in the south, along the Atlantic coasts of Portugal, Spain and France to south-western parts of the British Isles in the north. In the British Isles, it is only found natively in Dorset, Devon, Cornwall and one location in County Galway,Erica Ciliaris L. R. J. Rose, P. Bannister and S. B. Chapman Journal of Ecology Vol. 84, No. 4 (Aug., 1996), pp. 617–628 where it lives in bogs and wet heaths. It has also been introduced to Hampshire.

Pale Dog-violet
''Viola lactea'', also known by its common name pale dog violet, is a species of flowering planet of the family ''Violaceae''. Description ''Viola lactea'' has sparsely hairy creeping stems and a rosette of lanceolate leaves which are cuneate at their base. Each stem has one flower; the flowers are shaped similar to other violets and go from milky-violet to greyish-pink in colour, with the deep purple veins on the lower petal. The presence of green spurs at the back of its flower and the triangular stipules on its upper leaves being equal or longer in length than the leaf stalks differentiate ''V. lactea'' from other similar species. This species hybridizes easily with ''Viola riviniana'', which often occurs in the same habitat. The population of hybrid plants is thought to be increasing where both species are present, especially around the Cornish coast, as the ''V. riviniana x lactea'' hybrid outcompetes both its parent species. However, the hybrid plants are generally steri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
