Elevation

Elevation ranges from a minimum of 3m above sea level to a maximum of 167m. The mean average elevation is 77m (Natural England, 2010).

Landform and process

The Lincolnshire Wolds is dominated by a west-facing Chalk escarpment some 50m high. The Wolds comprise a high open, arable plateau stretching from the Humber past Louth to a ‘bluff’ above the Lincolnshire fens at East Keal. Within this upland rolling plain are a series of inward facing valleys. Between the villages of Donington-on-Bain and Tetford, an internal escarpment faces southwest overlooking ridges of glacial drift and valleys cut into sandstone. To the south-east the Chalk ridge is masked by clay till which creates more rounded forms as the Wolds fall down to the Middle Marsh of the adjacent Lincolnshire Coast and Marshes NCA around Alford (Lincolnshire Wolds Countryside Character Area Description).

Bedrock geology

Underlying Lower Cretaceous strata are revealed in the bottom of the valleys and at the foot of the scarp slope in the Wolds. The Lincolnshire Wolds is dominated by a west-facing Chalk escarpment some 50m high. These strata include ironstone, limestone and sandstone. Within the valleys of the rivers Bain and Lymn, Jurassic Kimmeridge Clay creates marshy poorly drained vales. The bedrock Now extensively moulded by glacial and periglacial action during the last ice age, when the drainage pattern Now altered by the deposition of sands, gravels and clay till (Lincolnshire Wolds Countryside Character Area Description).

Superficial deposits

In the south-east the overlying glacial till creates a rounded edge broken by deep valleys at Louth and Calceby (Lincolnshire Wolds Countryside Character Area Description)

Soils and Agriculture Classification

In the northern Wolds along the plateau tops are light chalky soils. On the valley sides, rivers have cut through to the underlying Red Chalk and Lower Cretaceous series. In the south-east from Louth to Candlesby, chalky boulder clays produce a heavy seasonally waterlogged soil giving rise to a gentle rounded landform. The Lymn valley has cut through to the Lower Cretaceous Spilsby Sandstone that provides parent material for well-drained, acidic loams. Along the river valleys of the Bain, Waring and Lymn glacial sands and gravels have produced deep, course and generally permeable loams. The presence of Upper Jurassic Kimmeridge Clay gives rise to localised areas of impermeable soil which is seasonally waterlogged (Lincolnshire Wolds Countryside Character Area Description).

The main grades of agricultural land in the NCA are broken down as follows (as a proportion of total land area) (Natural England, Provisional Agricultural Land Classification, 2019):

The Bain, Waring and Lymn drain southwards through the valleys to the southeast of the Wolds (Natural England, 2010).

Water quality

Nitrate Vulnerable Zones (NVZs) are areas designated as being at risk from agricultural nitrate pollution. These can impact surface water (waterbodies and waterways located above ground) and groundwater (water bodies and waterways located below ground).

Waterbodies such as lakes can also be designated as “eutrophic waters” if the enrichment of the waterbody by nitrate pollution causes accelerated growth of algae, impacting the quality of the water and the balance of organisms within it.

The following NVZs are located within the NCA (Environment Agency, Nitrate Vulnerable Zones Designations, 2021):

Water framework directive

River basin management plans cover river basin districts and describe the challenges that threaten the water environment and how these challenges can be managed and funded. The plans include the classification of water quality of surface waters and ground waters.

Note that numbers and figures in the body of the text are based on the 2014 profiles, unless otherwise stated. The maps contain live frequently updated datasets.

Total woodland cover

Ancient woodland is any area that has been wooded continuously since at least 1600 AD. National Forest Inventory (NFI) woodland includes all forests and woodlands (0.5 hectares and over). The total woodland cover within the NCA is as follows (Forestry Commission, National Forest Inventory, 2020; 2023; Natural England, Ancient Woodland, 2021; 2024; this does not consider Natural England’s ‘Ancient Woodland – Revised (England) – Completed Counties’ data as this is being updated in tranches and no full dataset is yet available):

Distribution and size of woodland and trees in the landscape

It is estimated that only 5 per cent woodland cover remains in this NCA compared with the national average of 8 per cent. A variety of woodland is present, although there is only one ancient semi-natural woodland on the chalk, which can be seen at Tetford Hill. This occurs on the scarp slope and consists of hazel, ash and wych elm with sycamore. Wet woodlands can be found on heavy soils in the valleys; particularly in the north around Stainton le Vale and in the south along the Bain and Lymn. In the north, oak-ash stands are most common, while in the south, alder carr frequently lines the streams. The most extensive woodlands occur on the calcareous clay soils in the south-east and largely consist of oak-ash-hazel woodlands (Lincolnshire Wolds Natural Area Profile, Lincolnshire Wolds Countryside Character Area Description).

Woodland types

A statistical breakdown of the area and type of woodland found across the NCA is detailed below (Forestry Commission, National Forest Inventory, 2020; 2023):

Boundary features and patterns

Note that numbers and figures in the body of the text are based on the 2014 profiles, unless otherwise stated.

Boundary features

Large rectilinear fields with clipped and degraded hedgerows date from late enclosure. Occasional shelter belts, concentrated on steeper sided valley and scarp slopes, emphasise the landform. The broad verges to some roads and tracks provide valuable herb-rich habitats (Lincolnshire Wolds Countryside Character Area Description, Countryside Quality Counts, 2003).

Field patterns

Land cover is predominantly arable with large rectilinear fields on the rolling plateau that are enclosed by clipped and ‘gappy’ hawthorn hedgerows. To the south-west there is a more complex pattern of medium-sized irregular fields where grazing combines with crop cultivation (Lincolnshire Wolds Countryside Character Area Description, Countryside Quality Counts, 2003).

Key habitats and species section contains a map

Note that numbers and figures in the body of the text are based on the 2014 profiles, unless otherwise stated. The maps contain live frequently updated datasets.

Habitat distribution/coverage

Calcareous, acidic and neutral grasslands are all present in this NCA. Calcareous grasslands are particularly important as they are species rich; only 44ha of this grassland type remains, the rest has been ‘improved’ or ploughed.

Nationally scarce plants include the fine-leaved sandwort. Road verges have some of the best surviving grassland habitats, particularly along ancient trackways and drove roads.

River headwaters and chalk streams constitute the main aquatic and riparian habitats. The River Bain contains particularly varied freshwater and riparian habitats. Notable species include otter, kingfisher, many invertebrates and locally scarce plants such as the southern and early marsh orchards. Another rare aquatic plant in the Wolds is the arrowhead.

Little woodland remains in the Wolds. Most large woods are found on the clay soils of the south-east scarp of the Wolds where they overlap with the Lincolnshire Coast and Marshes NCA.

Tetford Wood is a rare example of an ancient semi-natural wood on chalk soil. A number of important alder carr woods occur on spring lines and valley bottoms.

The white satin moth, along with the common fan-foot and the hook-tip are important moths that visit the woodlands. The 1960s saw the loss of all the woodland fritillary butterflies, but the numbers of white admiral and speckled wood butterflies are showing signs of recovery.

In addition the NCA contains important arable habitats. These support nationally important assemblages of farmland and arable birds (Lincolnshire Wolds Natural Area Profile, Natural England, 2011)

Key Habitats

The NCA contains the following areas of key main habitats, as mapped by the national Priority Habitat Inventory (Natural England, Priority Habitats Inventory, 2021; 2024; Natural England, Wood Pasture and Parkland, 2020). Note: lakes and ponds were not included in 2021 data:

Settlement and development patterns section contains a map

Note that numbers and figures in the body of the text are based on the 2014 profiles, unless otherwise stated. The maps contain live frequently updated datasets.

Settlement patterns

The Wolds has maintained a very sparse and dispersed settlement pattern over the last few centuries. Population density is marginally higher in the south-west river valleys while on parts of the high Wold there is no settlement at all. In the north villages are simple and nucleated while in the south a rectangular plan is often found with lanes enclosing a central area of cottages, farmhouses and paddocks, such as the village of Old Bolingbroke. Settlements tend to follow the physical features found within the NCA, such as the foot of the north-west scarp as at Tealby and Claxby, or the deep valleys within the chalk uplands as at Rothwell. To the south-west, villages such as Hemingby and Tetford are located in the river valleys. There are no major urban areas within the Wolds, but a series of small market towns, such as Louth in the east and Spilsby in the south lie at the foot of the hills (Lincolnshire Wolds Countryside Character Area Description, Countryside Quality Counts, 2003).

Main settlements

The main settlements are; Spilsby, Caistor, Binbrook and Barnetby le Wold and the fringes of Louth, Horncastle and Barton-upon-Humber. The total estimated population for this NCA (derived from ONS 2001 census data) is: 29,368 (Lincolnshire Wolds Countryside Character Area Description, Countryside Quality Counts, 2003, Natural England, 2012).

Local vernacular and building materials

The Wolds is not distinguished by a unified pattern of building materials or styles. The local chalk is generally a poor building material being crumbly and weak but Now used in medieval buildings however later, brick or other types of stone have been preferred. In the north-west the locally quarried Tealby Limestone and Claxby Ironstone can be seen. To the south the distinctive green or brown Spilsby Sandstone is used in the more ornate 14th- and 15th-century churches. Domestic buildings on the other hand are commonly built with brick and render walls, with pantile roofs (Lincolnshire Wolds Countryside Character Area Description, Countryside Quality Counts, 2003).

Key historic sites and features section contains a map

Note that numbers and figures in the body of the text are based on the 2014 profiles, unless otherwise stated. The maps contain live frequently updated datasets.

Origin of historic features

The Lincolnshire Wolds has produced evidence of some of the oldest human remains in Britain. Visible archaeology is strong with many barrows capping the hill tops, such as Six Barrows at Tathwell. From the Iron Age the chalk uplands had a well established network of trackways, an example of which is High Street and Bluestone Heath Road. The Romans built east-west roads to access the coastal salt industry. Village names withham orton are evidence of the permanent and extensive settlement undertaken in the Saxon period. Those with names ending in -by or -thorpe are likely to be of Danish origin. Deserted village locations have been identified, such as Calcethorpe, thought to be related to the Black Death and the growth of the wool industry. Post-medieval ironwork sites are also found as at Claxby (Draft Historic Profile, Countryside Quality Counts, Countryside Character Area Description).

Experiential qualities

Note that numbers and figures in the body of the text are based on the 2014 profiles, unless otherwise stated.

Tranquillity

Based on the CPRE map of tranquillity (2006) the least tranquil areas in the NCA are around the main settlements such as Louth. The most tranquil areas can be found on the high, open Wolds.

A breakdown of tranquillity values for this NCA are detailed in the table below (CPRE, Tranquillity Map, 2006):

Dark skies

Light pollution is a generic term referring to artificial light that shines where it is neither wanted nor needed, and can impact on people’s experience of the countryside within the NCAs. CPRE host an interactive map, depicting the light pollution and dark skies within the NCA.

Intrusion

The 2007 Intrusion Map (CPRE) shows the extent to which rural landscapes are ‘intruded on’ from urban development, noise (primarily traffic noise), and other sources of visual and auditory intrusion. This shows a similar picture to the tranquillity data with a fairly low rate of disturbance in the more rural isolated areas with greater disturbance around settlements and the road network. A breakdown of intrusion values for this NCA is detailed in the table overleaf

A breakdown of intrusion values for this NCA is detailed in the table below (CPRE, Intrusion Map, 2007):

The notable trend from the 1960s to 2007 is a very small increase in the percentage of undisturbed land in this NCA.
