Elevation

The Quantocks rise to a maximum height of 381m from a minimum of 62m. The mean elevation is 210m (Natural England, 2010).

Landform and process

The Quantock valleys form a distinctive pattern. On the steep, west-facing scarp slope they are short, steep and wooded with small villages and hamlets on the spring lines at the slope foot. To the east and south there are much more gentle valleys, commonly with plantations, ending in the larger villages and parklands at the end of the Vale of Taunton. Around the edges of the Quantock Hills there is a transition to a gentler lowland landscape (Exmoor and the Quantock Hills Natural Area Profile, Quantock Hills Countryside Character Area description).

Bedrock geology

The Quantocks are formed from thick sequences of slates and sandstones of Devonian age that were deposited by large deltas that built out into a shallow sea. They are surrounded by Triassic mudstones and sandstones which represent the deposits of large river systems that crossed a desert plain. The sandstones underlying the north of the hills are Trentishoe and Hangman Sandstones, forming the highest ground of the hills. The south is underlain by Leighland Slates (with thin limestones) and Morte Slates. These rocks are bordered to the south and east by a belt of red Triassic sandstones and elsewhere by mudstones and halites from the same period. The western margin of the Quantocks is sharply defined by the major Cothelstone Fault which is part of a group of faults which display evidence of a complex history involving Variscan and later movement (Exmoor and the Quantock Hills Natural Area Profile, Quantock Hills Countryside Character Area description, British Geological Survey maps).

Superficial deposits

There are minor deposits of alluvium along watercourses. Unlike much of the rest of Britain, Somerset did not experience the full effects of the repeated advances of ice sheets, as the southward movement of the most recent ice sheets did not extend into the county. During these glacial periods it is likely that much of the county resembled the tundra of today’s arctic provinces (Exmoor and the Quantock Hills Natural Area Profile, Quantock Hills Countryside Character Area description, British Geological Survey maps).

Along the steeper western scarp, streams have cut down to form deep, incised combes that are thickly wooded. In contrast, to the east the land falls as a more gentle dip slope with long, broad valleys through which streams flow into the Vale of Taunton.

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):

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

Beech hedgebanks bound the rectangular fields around the edge of the open plateau and on the lower agricultural land in the south. Mixed hedgerows are used elsewhere and stone-faced banks or earth banks are used within the combes. Many hedgerows were planted with beech and where these have been left to grow up there are now prominent lines of trees (Quantock Hills Countryside Character Area description, Countryside Quality Counts, 2003).

Field patterns

Pastures and arable fields are divided into a patchwork of irregular shapes by a network of hedgerows dotted with trees (Quantock Hills Countryside Character Area description, Countryside Quality Counts, 2003).

Habitat distribution/coverage

Heath characterises the higher hills and ridges of much of the western, central and northern parts of the area. The higher hills and ridges are covered by tracts of upland heath, changing in floristic character and content to form lowland heath in the north as the hills reduce in height. The transition between upland and lowland heath occurs repeatedly along the crest of the scarp slope as the high ridge undulates. To the east, much of the dip slope, and particularly the valleys and combes are cloaked in woodland; upland oak woods, lowland beech and yew woods, and lowland mixed woods. Lowland mixed woods are also found on more gentle slopes and valleys to the south of the area (Exmoor & Quantock Hills Natural Area Profile).

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

Settlement is sparse, consisting of isolated farms, hamlets or small villages located along the spring line or tucked into the narrow combes and valleys. The pre-enclosure settlement pattern below the heathland can still be seen today. Scarp-foot villages lie along the western edge and there is scattered settlement on the gentler eastern slopes. Larger villages like Nether Stowey lie at the junction with the Vale of Taunton (Quantock Hills Countryside Character Area description; Countryside Quality Counts, 2003).

Main settlements

There are no main settlements in the area. West Quantoxhead to the north and Kingston St Mary in the south are the largest villages (Quantock Hills Countryside Character Area description, Countryside Quality Counts, 2003).

Local vernacular and building materials

Many farmsteads are built of local slate and sandstone rubble; the Triassic red sandstone of the Quantock Hills is widely used in the area. The design of the church towers is notable; ambitious, prominent and decorated towers. Larger manor houses and mansions, many of Tudor or 18th century origin, lay around the fringes of the area with estate lands and estate cottages a component of the landscape running up to the high ridge. Notable houses and estates include Crowcombe Court, Cothelstone Manor and Tetton to the west; St Audries and East Quantoxhead (both outside of the area, but closely associated with it) to the north; Hestercombe and Fyne Court to the south; and Doddington, Enmore Castle and Halswell to the east. These larger buildings also make use of the Triassic red sandstone, although red brick is also used in some of the larger country houses and estate buildings that are scattered about the Quantock landscape (Quantock Hills 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 landscape of the Quantock Hills has been shaped by human influences since the Bronze Age when numerous small round burial mounds, which can still be seen throughout the hills, were constructed. The name of the hills is thought to be derived from the Celtic word Cantuc, meaning rim or circle and relating to the curved line of the hills above the surrounding lowlands. Although there is evidence of Mesolithic and Neolithic occupation around the edges of the area, the standing stones, stone circles and barrows of the Bronze Age are by far the most prominent survivors from the prehistoric landscape. The Quantock Hills were never densely wooded, but substantial parklands were developed, many of which were the basis of 18th and 19th century landscaped parks. Settlements were probably more frequent than they are today and deserted sites can still be seen around the edges of the area. In the late 18th and early 19th centuries, small trials for copper mining developed in the Quantock Hills. In the 1920s, the planting of large conifer plantations on the Quantock dip slopes brought further change (Draft Historic Profile, Countryside Quality Counts, Countryside Character Area description).
