General
Description
The Chalk Downland Ridges are distinguished by series of small hills
forming a ridgeline with sculptural and often dramatic scarps, although
these are less frequent than found within the Chalk and Clay Landscape
Character Types LT6 and 7. Due to the topography, these landforms have
few roads or settlements associated with them and a low density of farmsteads.
The type is a mix of arable, with a weak hedgerow structure and groups
of hedgeless fields creating further larger open expansive areas, and
pasture. Woodlands predominantly located on the more inaccessible slopes,
including scarps and adjacent farmsteads to provide enclosure.
Location
The Chalk Downland Ridges are similar in character to the Open Chalklands
to the west and east but are distinguished by their prominent topography
and a greater extent of unimproved chalk grassland. There is one area
within the Borough where this Landscape Type occurs, to the east of Shipton
Bellinger, on the western side of the Borough.
Physical Influences
Geology and Soils: Predominantly underlying
Chalk geology.
Landform: A loose alignment of small
hills, ridges and valleys, with some scarps, which contrast with the flatter
open plains of the Open Chalklands Landscape Type.
Drainage: A pervious base, with no surface drainage.
Biodiversity and Vegetation Pattern
This type is characterised by pastoral agricultural systems with calcareous
downland and woodland. Farming is difficult in these areas and so the
effect of intensive agriculture upon the surroundings is much less than
other more easily cultivated areas, in this respect, remnants of unimproved
calcareous grassland are frequent and have great conservation value. Arable
farming is found where deeper soils occur.
Woodland is typically found on the steeper slopes and the crowns of
the hilltops. Typical species are Yew, Whitebeam and Beech with some Ash,
Field Maple and Oak.
Notable habitats
Unimproved chalk grassland
Historical Influences
Topographic highpoints within a landscape have attracted interest for
thousands of years: as ridgeways by which the landscape could be traversed,
as highly visible locations for the burial of dead and as a provider of
readily defensible positions for local communities. Consequently burial
mounds or barrows (Bronze Age) and hillforts (Iron Age) are prevalent
upon these high points and can still be clearly identified today. Also
present may be Celtic field systems (Iron Age) which have survived within
land deemed too marginal to be worth bringing into cultivation.
The Chalk Downland Ridges, which are to be found upon the western border
of the Borough, appear to retain several elements of largely later post-medieval
formal (parliamentary) and informal enclosure. These tracts of agricultural
land cut through the downland ridge at apparent right angles to the ridgeline
although elements of downland survive relatively intact.
Settlement Pattern
No modern settlements can be identified within the Chalk Downland Ridges.
No farmsteads are located upon the ridge but tend to take advantage of
the lower more gentle relief provided away from the ridge lines and only
occasionally occupying the pasture present upon the ridge.
Communication Network
Roadways extend down the slopes of the downland ridge and only very
rarely across it. This allows access to the lower portions of the valley
and up onto the pasture lands often located upon the downland ridges.
Key Natural and Cultural Landscape Issues
Intensification of farming resulting in large fields and the loss of
biodiversity and archaeological features
Isolation of small patches of unimproved chalk grassland habitat sue
to arable or scrub encroachment
Hedgerow fragmentation and loss
Declining farmland bird populations.
