British NVC Community W7
NVC community W7 (Alnus glutinosa - Fraxinus excelsior - Lysimachia nemorum woodland) is one of the woodland communities in the British National Vegetation Classification system; it is one of seven woodland communities in the NVC classed as "wet woodlands". Community composition Alder is often not as abundant as in the previous types. Ash and/or silver birch are frequent with mixtures of common sallow, hazel and hawthorn in the shrub layer Stratification in the field of ecology refers to the vertical layering of a habitat; the arrangement of vegetation in layers. It classifies the layers (sing. ''stratum'', pl. ''strata'') of vegetation largely according to the different heights to w .... Ground flora includes meadow sweet, yellow pimpernel, lady fern, rough stalked meadow grass, creeping soft grass, creeping buttercup and/or golden saxifrage. These are found on base rich flushes with gleyed mineral soils. Distribution It is the commonest alder type in upland woods; it does o ...

Alnus Glutinosa
''Alnus glutinosa'', the common alder, black alder, European alder, European black alder, or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations where its association with the bacterium ''Frankia alni'' enables it to grow in poor quality soils. It is a medium-sized, short-lived tree growing to a height of up to 30 metres (98 feet). It has short-stalked rounded leaves and separate male and female flowers in the form of catkins. The small, rounded fruits are cone-like and the seeds are dispersed by wind and water. The common alder provides food and shelter for wildlife, with a number of insects, lichens and fungi being completely dependent on the tree. It is a pioneer species, colonising vacant land and forming mixed forests as other trees appear in its wake. Eventually common alder dies out of woodlands because the seedlings need more light than is available on the forest floor. I ...

Fraxinus Excelsior
''Fraxinus excelsior'', known as the ash, or European ash or common ash to distinguish it from other types of ash, is a flowering plant species in the olive family Oleaceae. It is native throughout mainland Europe east to the Caucasus and Alborz mountains, and Britain and Ireland, the latter determining its western boundary. The northernmost location is in the Trondheimsfjord region of Norway.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Den virtuella floran''Fraxinus excelsior'' distribution/ref> The species is widely cultivated and reportedly naturalised in New Zealand and in scattered locales in the United States and Canada. Description It is a large deciduous tree growing to (exceptionally to ) tall with a trunk up to (exceptionally to ) diameter, with a tall, narrow crown. The bark is smooth and pale grey on young trees, becoming thick and vertically fissured on old trees. The shoots are stout, greenish-grey, with jet-black buds (which distinguish ...

Lysimachia Nemorum
''Lysimachia nemorum'', the yellow pimpernel, is a perennial flowering plant in the family Primulaceae. Description ''Lysimachia nemorum'' is an evergreen creeping perennial herbaceous plant growing up to about 40 cm. The bright green leaves are opposite, ovate, pointed and without teeth or hairs. The yellow flowers are about 8mm across, borne singly on long stalks in the axil of each leaf. They have five very narrow sepals, five pointed petals and five stamens. The ovary is superior, forming a capsule. Distribution ''Lysimachia nemorum'' is native to Great Britain and Ireland Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. It is separated from Great Britain to its east by the North Channel (Grea ... and the east of mainland Europe from the Pyrenees in the south to eastern Norway in the nort Its habitat is damp woodland.

Woodland And Scrub Communities In The British National Vegetation Classification System
This article gives an overview of the woodland and scrub communities in the British National Vegetation Classification system. Introduction The woodland and scrub communities of the NVC were described in Volume 1 of British Plant Communities, first published in 1991. In total, 25 woodland/scrub communities have been identified, consisting of 19 woodland communities, four communities classed as scrub and 2 as underscrub. The woodland communities consist of: * Six mixed deciduous or oak/birch woodland communities, which between them are found throughout Britain * Three Beech woodland communities, found mainly in southern England * A Yew woodland community, almost completely restricted to southeast England (community W13) * A Scots Pine woodland community, restricted to Scotland * A Juniper woodland community (community W19) * Seven wet woodland communities, characterised by the presence of alder, birch and willows (communities W1, W2, W3, W4, W5, W6 and W7). * Communiti ...

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'' ...

Wet Woodland
A wet woodland is a type of plant community. It is a biodiversity habitat in the United Kingdom as part of the British National Vegetation Classification system. Wet woodland A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see ...s occurs on poorly drained or seasonally wet soils. They may occur in river valleys, the surroundings of mires and raised bogs, bog, the transition zones between open water and drier ground, and beside small winding streams. British National Vegetation Classification Within the British National Vegetation Classification, seven types of wet woodland are recognised as part of the Woodland and scrub communities in the British National Vegetation Classification system: *W1.

Shrub Layer
Stratification in the field of ecology refers to the vertical layering of a habitat; the arrangement of vegetation in layers. It classifies the layers (sing. ''stratum'', pl. ''strata'') of vegetation largely according to the different heights to which their plants grow. The individual layers are inhabited by different animal and plant communities (stratozones). Vertical structure in terrestrial plant habitats The following layers are generally distinguished: forest floor (root and moss layers), herb, shrub, understory and canopy layers. These vegetation layers are primarily determined by the height of their individual plants, the different elements may however have a range of heights. The actual layer is characterised by the height range in which the vast majority of photosynthetic organs (predominantly leaves) are found. Taller species will have part of their shoot system in the underlying layers. In addition to the above-ground stratification there is also a “root layer”. ...
