Draft:East Anglian Chalk

From Wikipedia, the free encyclopedia



East Anglian Chalk is a National Character Area (NCA) with its underlying geology as Upper Cretaceous Chalk.[1]

History

[edit]

Early farmsteads were developed in villages with their open fields and pastures. Reorganisation and enlargement of village based farmsteads, and establishment of some isolated farmsteads, associated with mostly 18th- to 19th-century enclosure and the creation of a landscape of straight roads, tree belts, copses and large, regular enclosures.[2]

Physical characteristics

[edit]

Landscape and land use

[edit]

The East Anglian Chalk of Cambridgeshire and north-west Essex forms a narrow continuation of the rolling chalk ridge that runs south-west–north-east across southern England. Of the landscape, 92.7% is open countryside, 88.3% of which is cultivated. There are no parts of the landscape falling within an AONB or having National Park status. The landscape contains 2.7% of woodland.[2]

Rivers

[edit]

Notable rivers such as the Ivel rise in the East Anglian Chalk.[3] River Rhee rises at Ashwell Springs. Another river, which is the Granta, starts in Essex and flows north near Saffron Walden.[4]

Geology and ecology

[edit]

The East Anglian Chalk has an underlying geology of the Upper Cretaceous Chalk, which is covered in a surface deposit of ice and river-deposited material laid down during the last ice age.[1] Deposits of Palaeogene and Pleistocene has an extensive coverage in the East Anglian Chalk, which influences groundwater composition.[5] On the fen edge in the north of the NCA is Chippenham Fen, a wetland. Most sites of biodiversity interest today are remnants of the once extensive chalk grassland scattered throughout the natural area. The managed grasslands are golf courses of the Gog Magog Hills and Therfield Heath. Therfield Heath is a Site of Special Scientific Interest (SSSI) and has chalk grassland with species such as upright brome (Bromus erectus), red fescue (Festuca rubra) and pasque flower. [6]
