What is a fen geography?
fen, type of wetland ecosystem, especially a low-lying area, wholly or partly covered with water and dominated by grasses and grasslike plants such as sedges and reeds. Fens develop on slopes, in depressions, or on flats as a result of sustained flows of mineral-rich groundwater in the root zone.
What’s the difference between a swamp and a fen?
Swamps are forested, marshes are populated by herbaceous plants. Bogs accumulate peat. Fens have neutral or alkaline water chemistry.
What does a fen wetland look like?
Another bog-like wetland is called a fen. Like bogs, fens formed when glaciers retreated. Grasses and sedges are common plants in fens and fens often look like meadows. They are like bogs because they have peat deposits in them, but unlike bogs some of their water comes from small streams and groundwater.
What is a fen meadow?
Fen Meadow is an area of open space, it is predominantly a grassland meadow which has been managed in a traditional manner, and consequently is important to maintaining local bio-diversity.
How fens are formed?
Fens are peat-forming wetlands that rely on groundwater input and require thousands of years to develop and cannot easily be restored once destroyed. Fens are also hotspots of biodiversity. They often are home to rare plants, insects, and small mammals.
How do you identify a fen?
Fens are peatlands characterized by a high water table, but with very slow internal drainage by seepage. Similar to bogs, the surface water in fens is also generally nutrient poor and the peat layer is at least 40 cm thick.
How are fens created?
The history of the Fens as a wetland landscape began around 10,000 years ago when rising sea levels caused Britain to become an island. Marine and estuarine clays and silts were deposited as the sea underwent a succession of advances and retreats. These formed the ‘Silt Fens’.
How is a fen formed?
What plants grow in a fen?
The sedge meadow is typically the largest component of the fen, and shrubby cinquefoil (Potentilla fruticosa), sedges, and wet prairie species joe-pye weed (Eupatorium maculatum), boneset (E. perfoliatum), and asters are common in this vegetation zone.
Where exactly are the Fens?
Fens, also called Fenland, natural region of about 15,500 sq mi (40,100 sq km) of reclaimed marshland in eastern England, extending north to south between Lincoln and Cambridge.
How was the Fens formed?
What did the Fens look like?
A long time ago, the fens were watery marshes. They were wild, dangerous places filled with tall grasses and flat wetlands. There were also areas, or islands, of high land in the fens. Ely is sometimes known as The Isle of Ely because it was built on an island of solid ground surrounded by the marsh.
What are bogs and fens?
Although both bogs and fens are similar types of wetlands as they are both considered peatlands, what sets them apart from each other is the source of their water supply. Fens typically are fed by a steady source of ground water whereas bogs are usually enclosed depressions filled by rain water.
Where are the Fens?
How were the Fens created?
How are bogs and fens the same?
Bogs store and release water to and from the surrounding land, but are not connected to a system of lakes or streams. Bogs are nutrient poor and generally have low plant diversity as a result. Fens, on the other hand, are connected to slow, but flowing water of small lakes and streams.
