Mires In The British National Vegetation Classification System
This article gives an overview of the Bog, 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 Heaths in the British National Vegetation Classification system, heath communities. In total, 38 mire communities have been identified. The mire communities consist of a number of separate subgroups. * five bog plane communities (British NVC community M17, M17, British NVC community M18, M18, British NVC community M19, M19, British NVC community M20, M20 and British NVC community M21, M21) * two wet heath communities (British NVC community M15, M15 and British NVC community M16, M16) * four bog-pool communities (British NVC community M1, M1, British NVC community M2, M2, British NVC community M3, M3 and British NVC community M4, M4) * four base-poor small sedge & rush communities (British NVC community M5, M5, Bri ...

Plant Communities
A plant community is a collection or Association (ecology), 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 comprehe ...

Fen-meadow
A fen-meadow is a type of peatland, common in North America and Europe, that receives water from precipitation and groundwater. Habitat The continuous flow of mineral-rich and nutrient-poor acidic groundwater through fen-meadow topsoil fosters endemic plant species, including plant associations such as '' Juncus subnodulosus-Cirsium palustre'', and protects them from floods, droughts, and nutrient pollution. Degradation by human activity Fen meadows have been severely impacted by farming, resulting in hydrological changes, acidification, and nutrient pollution, leaving few preserved into the 21st century. Compositional transformations and increased groundwater flow have the greatest effect this habitat and can degrade peat. Keeping water tables at appropriate levels allows fen meadows to regulate themselves. Restoration efforts are difficult and no deteriorated fens have been fully restored. Therefore, preservation efforts focus on maintaining fen meadows with slight to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
