A lowland district of eastern England west and south of the Wash. Early attempts by the Romans to drain the area were abandoned by Anglo-Saxon times. Modern-day reclamation of the Fens began in the 17th century. an area of flat land in eastern England which used to be partly covered by the sea and now produces good crops
A plural form of fan used by enthusiasts of science fiction, fantasy, and anime, partly from whimsy and partly to distinguish themselves from fans of sport, etc
Fen is used to refer to an area of low, flat, wet land, especially in the east of England. the flat fen lands near Cambridge. Low, flat, swampy land; a bog or marsh. fenland an area of low flat wet land, especially in Eastern England
wetlands that receive nutrients via direct contact with mineral enriched groundwater A "poor" fen has very low concentrations of plant nutrients and floristically resembles a bog A "rich" fen has relatively high concentrations of nutrients, but is still characterized by the accumulation of peat (though this is likely to be primarily from the remains of plants other than sphagnum mosses, such as sedges and brown mosses)
A MIRE that receives water from the surrounding land (unlike a BOG) and hence nutrients from rocks and soils Because of this, a fen supports different communities of plants and animals than a BOG
low-lying wet land with grassy vegetation; usually is a transition zone between land and water; "thousands of acres of marshland"; "the fens of eastern England"
A plural form of fan used by enthusiasts of science fiction, fantasy, and anime, partly from whimsy and partly to distinguish themselves from fans of sport, etc. (by analogy with men as the plural of man)
A peat accumulating wetland that receives some drainage from surrounding mineral soils and usually supports marsh-like vegetation These areas are richer in nutrients and less acidic than bogs The soils under fens are peat (Histosols) if the fen has been present for a while See also bog, pocosin, swamp, and wetland
Nutrient rich, organic wetland influenced by mineral-bearing groundwater Forms a moderately decomposed peat near the top The surface is usually level and mostly covered with sedges, brown mosses, grasses and willow and birch trees and shrubs
A hyperspace alien species attracted to bright shinny objects and known to mate with space vessels This happened to the Excalibur An alternative definition : A synonym for Babylon 5 fan coined by JMS It is not known if they mate with him
a type of wetland that accumulates peat deposits, but not as much as a bog Fens are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium
A sedge-moss type of wetland produced where slightly alkaline water emerges at the surface (Bogs have similar types of vegetation but tend to be acid ) Peat-forming freshwater wetlands are generally non-acidic, receive nutrients mainly from groundwater sources, and are dominated by marsh-like vegetation
A sedge or reed dominated peatland, often with some shrubs or small trees, characterized by mineral-rich, aerated waters at or near the surface Fens with lower calcium content often evolve into Sphagnum lawns and, eventually, acid bogs An Old English word
A type of wetland that accumulates peat deposits Fens are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium (See: wetlands )
Low marshy land, wetlands, or bog, often partially and/or periodically covered with water Fenland is similar to peat bog but generally has more nutrients in the water supply
A type of wetland that accumulates peat deposits; they are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium (Source: Carbon Dioxide Information Analysis Center, 1990)
A wetland that is at the watertable and has a direct hydraulic connection to it, fens accumulate peat and the vegetation is dominated by sphagnum moss and small herbs
