Aquatic Communities In The British National Vegetation Classification System
This article gives an overview of the aquatic communities in the British National Vegetation Classification system. Introduction The aquatic communities of the NVC were described in Volume 4 of '' British Plant Communities'', first published in 1995, along with the swamps and tall-herb fens. In total, 24 aquatic communities have been identified. The aquatic communities fall into the following six groups: * four communities of the water surface and sub-surface, in which duckweeds and/or Frogbit are the constant species; these communities ( A1, A2, A3 and A4) are found in moderately-rich to eutrophic standing waters * eight free-floating or rooted and submerged, pondweed communities ( A5, A6, A11, A12, A13, A14, A15 and A21) * six communities in which rooted water-lilies and pondweeds with floating leaves are the constant species ( A7, A8, A9, A10, A19 and A20) * three communities in which water-crowfoots and/or starworts are the constant species ( A16, A17 an ...

Aquatic Plant
Aquatic plants, also referred to as hydrophytes, are vascular plants and Non-vascular plant, non-vascular plants that have adapted to live in aquatic ecosystem, aquatic environments (marine ecosystem, saltwater or freshwater ecosystem, freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate (marine biology), substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include Nymphaeaceae, waterlily, Nelumbo, lotus, duckweeds, mosquito fern, floating heart, water milfoils, Hippuris, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptation (biology), adaptations for prolonged inundation in water, and for buoyancy, floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British NVC Community A18
Ranunculetum fluitantis is one of the 24 Aquatic plant communities (A18) included in the British National Vegetation Classification (NVC). The vegetation type or community comprises stands of submerged vegetation dominated by clumps of River water crowfoot. Few other plants are found with any frequency among the denser stands but there can be ''Myriophyllum''; ''Potamogeton perfoliatus ''Potamogeton perfoliatus'' (claspingleaf pondweed, perfoliate pondweed, redhead grass) is a perennial aquatic plant in the family Potamogetonaceae occurring in both standing and flowing freshwater habitats.

Water-crowfoot
''Ranunculus'' is a large genus of about 1750 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots. The genus is distributed worldwide, primarily in temperate and montane regions. The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup ''Ranunculus repens'', which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup ''Ranunculus bulbosus'' and the much taller meadow buttercup ''Ranunculus acris''. In ornamental gardens, all three are often regarded as weeds. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds. The water crowfoots (''Ranunculus'' subgenus ''Batrachium''), which grow in still or running water, are sometimes treated in a separa ...

British NVC Community A9
__NOTOC__ The ''Potamogeton natans'' community (NVC community A9) is one of the aquatic communities in the British National Vegetation Classification system. It is a comparatively widely distributed community. There are three subcommunities. Community composition One constant species is found in this community, Broad-leaved Pondweed (''Potamogeton natans''). No rare species are associated with the community. Distribution This community is found widely throughout Britain Britain most often refers to: * Great Britain, a large island comprising the countries of England, Scotland and Wales * The United Kingdom of Great Britain and Northern Ireland, a sovereign state in Europe comprising Great Britain and the north-eas ....
