British NVC Community W2
__NOTOC__ NVC community W2 (''Salix cinerea - Betula pubescens - Phragmites australis'' 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". This is a fairly locally distributed community. There are two subcommunities. Community composition Three constant species is found in this community, Grey Willow (''Salix cinerea''), Downy Birch (''Betula pubescens'') and Common Reed (''Phragmites australis''). Six rare species are also associated with the community: * Elongated Sedge (''Carex elongata'') * Crested Buckler-fern (''Dryopteris cristata'') * the fern ''Dryopteris'' × ''uliginosa'', the hybrid of Crested Buckler-fern and Narrow Buckler-fern ('' D. carthusiana'') * Milk-parsley (''Peucedanum palustre'') * Round-leaved Wintergreen (''Pyrola rotundifolia'') * Marsh Fern (''Thelypteris palustris'') Distribution This community is distributed in tw ...

Salix Cinerea
''Salix cinerea'' (common sallow, grey sallow, grey willow, grey-leaved sallow, large grey willow, pussy willow, rusty sallow) is a species of willow native to Europe and western Asia.Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. .Christensen, K. I., & Nielsen, H. (1992). Rust-pil (''Salix cinerea'' subsp. ''oleifolia'') - en overset pil i Danmark og Skandinavien. ''Dansk Dendrologisk Årsskrift'' 10: 5-17. The plant provides a great deal of nectar for pollinators. It was rated in the top 10, with a ranking of second place, 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. Plant It is a deciduous shrub or small tree growing 4–15 metres (13–50 ft) tall. The leaves are spirally arranged, 2–9 cm (1– in) long and 1–3 cm (– in) broad (exceptionally up to 16 cm ...

Thelypteris Palustris
''Thelypteris palustris'', the marsh fern, or eastern marsh fern, is a species of fern native to eastern North America and across Eurasia Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago .... It prefers to grow in marshy situations in full sun. The species epithet ''palustris'' is Latin for "of the marsh" and indicates its common habitat. It is the only known host plant for '' Fagitana littera'', the marsh fern moth.Pocketguide to Eastern Wetlands By T.

Sphagnum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuges, ericaceous shrubs, as well as orchids and carnivorous plant ...

Filipendula Ulmaria
''Filipendula ulmaria'', commonly known as meadowsweet or mead wort, is a perennial herbaceous plant in the family Rosaceae that grows in damp meadows. It is native throughout most of Europe and Western Asia (Near east and Middle east). It has been introduced and naturalised in North America. Meadowsweet has also been referred to as queen of the meadow, pride of the meadow, meadow-wort, meadow queen, lady of the meadow, dollof, meadsweet, and bridewort. Description The stems, growing up to 120 cm, are tall, erect and furrowed, reddish to sometimes purple. The leaves are dark-green on the upper side and whitish and downy underneath, much divided, interruptedly pinnate, having a few large serrate leaflets and small intermediate ones. Terminal leaflets are large, 4–8 cm long, and three- to five-lobed. Meadowsweet has delicate, graceful, creamy-white flowers clustered close together in irregularly-branched cymes, having a very strong, sweet smell redolent of antisep ...

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 ...

Yorkshire
Yorkshire ( ; abbreviated Yorks), formally known as the County of York, is a Historic counties of England, historic county in northern England and by far the largest in the United Kingdom. Because of its large area in comparison with other English counties, functions have been undertaken over time by its subdivisions, which have also been subject to History of local government in Yorkshire, periodic reform. Throughout these changes, Yorkshire has continued to be recognised as a geographic territory and cultural region. The name is familiar and well understood across the United Kingdom and is in common use in the media and the Yorkshire Regiment, military, and also features in the titles of current areas of civil administration such as North Yorkshire, South Yorkshire, West Yorkshire and the East Riding of Yorkshire. Within the borders of the historic county of Yorkshire are large stretches of countryside, including the Yorkshire Dales, North York Moors and Peak District nationa ...

South Wales
South Wales ( cy, De Cymru) is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia. A point of some discussion is whether the first element of the name should be capitalised: 'south Wales' or 'South Wales'. As the name is a geographical expression rather than a specific area with well-defined borders, style guides such as those of the BBC and ''The Guardian'' use the form 'south Wales'. In a more authoritative style guide, the Welsh Government, in their international gateway website, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest England
North West England is one of nine official regions of England and consists of the administrative counties of Cheshire, Cumbria, Greater Manchester, Lancashire and Merseyside. The North West had a population of 7,052,000 in 2011. It is the third-most-populated region in the United Kingdom, after the South East and Greater London. The largest settlements are Manchester and Liverpool. Subdivisions The official region consists of the following subdivisions: After abolition of the Greater Manchester and Merseyside County Councils in 1986, power was transferred to the metropolitan boroughs, making them equivalent to unitary authorities. In April 2011, Greater Manchester gained a top-tier administrative body in the form of the Greater Manchester Combined Authority, which means the 10 Greater Manchester boroughs are once again second-tier authorities. Geography North West England is bounded to the east by the Pennines and to the west by the Irish Sea. The region exten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Anglia
East Anglia is an area in the East of England, often defined as including the counties of Norfolk, Suffolk and Cambridgeshire. The name derives from the Anglo-Saxon kingdom of the East Angles, a people whose name originated in Anglia, in what is now Northern Germany. Area Definitions of what constitutes East Anglia vary. The Anglo-Saxon Kingdom of East Anglia, established in the 6th century, originally consisted of the modern counties of Norfolk and Suffolk and expanded west into at least part of Cambridgeshire, typically the northernmost parts known as The Fens. The modern NUTS 3 statistical unit of East Anglia comprises Norfolk, Suffolk and Cambridgeshire (including the City of Peterborough unitary authority). Those three counties have formed the Roman Catholic Diocese of East Anglia since 1976, and were the subject of a possible government devolution package in 2016. Essex has sometimes been included in definitions of East Anglia, including by the London Society o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Betula Pubescens
''Betula pubescens'' (syn. ''Betula alba''), commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch (''B. pendula''), but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch (''B. nana''). Six varieties are recognised and it hybridises with the silver and dwarf birches. A number of cultivars have been developed but many are no longer in cultivation. The larva of the autumnal moth (''Epirrita autumnata'') feeds on the foliage and in some years, large areas of birch forest can be defoliated by this insect. Many fungi are associated with the tree and certain pathogenic fungi are the causal agents of birch dieback disease. The tree is a pioneer species ...
