Landscapes and soils
 


The varied landscapes of the East of England reflect thousands of years of natural and human activity working on a heritage of geology, soils and landforms. Some of this variety is shown below.

An East Anglian Chalk landscape at Barkway, Herts. The ridge in the background marks an escarpment, developed where the hard Chalk Rock horizon of the Upper Chalk has resisted erosion. The calcareous, silty soils are suited to growing barley. A radio mast is making use of the elevated location here, at 148m OD.

A Breckland heath landscape at Wretham, Norfolk. Thin sandy glacial and aeolian 'drift' over chalk bedrock gives the Breckland a distinctive mosaic of acidic and chalky soils, which support a diverse flora. Traditionally such heaths were farmed as sheep walks and rabbit warrens. This land is used for grazing sheep, and is part of STANTA military training area.

An Essex coastal lowland landscape, with a view over the Blackwater estuary to the Dengie peninsula. The soils are heavy, impermeable London Clay, often waterlogged in winter. Bradwell nuclear power station can be seen in the distance. This landscape is likely to be modified in the future by rising sea levels.

A Fenland landscape at Fodder Fen, near Littleport, Cambs. Peat soils of freshwater origin overlie marine silts and clays deposited in an estuarine environment over 4,000 years ago. Loose, fertile peat soils make this a prime area for growing vegetables and cereals, although peat shrinkage due to drainage is bringing less fertile subsoils closer to the surface.

The variety of the region's landscapes has been summarised as a series of twenty-one National Character Areas. These are based on the geodiversity of each area, and also include historical and cultural factors such as settlement and landuse. They provide a useful guide to the region's local distinctiveness.

The landscape is made up of an intricate mosaic of different soils, giving the region much of its natural character, and supporting varied wildlife habitats and types of agriculture. They represent ten thousand years of development since the last Ice Age, though some of the region’s soils may be even older and show influence of weathering dating back to earlier, warm interglacial periods.

Over the centuries, human activity has shaped and transformed our natural heritage of soils and landforms into the settled landscapes we see today, with all their variations in human land-use. These patterned landscapes have been characterised as thirty-one Landscape Character Types.
