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] |
Plant Communities
A plant community is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance. In many cases there are several soil types present within a given plant community. This is because the soil type within an area is influenced by two factors, the rate at which water infiltrates or exits (via evapotranspiration) the soil, as well as the rate at which organic matter (any carbon-based compound within the environment, such as decaying plant matter) enters or decays from the soil. Plant communities are studied substantially by ecologists, due to providing information on the effects of dispersal, tolerance to environmental conditions, and response to disturbance of a variety of plant species, information valuable to the comprehension of various plant ...
