Elevation

The Pevensey Levels NCA is a low-lying landscape. The maximum elevation is 62 m. The mean elevation is 7m (Natural England, 2010).

Landform and process

This NCA is an open, flat and low lying landscape with pockets of raised land often described as ‘eyes’. At the end of the last glaciation, rising sea-levels flooded the lower reaches of the coastal river valleys resulting in the creation of a tidal estuary. The present day levels were under water and consisted of a wide shallow bay backed by the rising ground of the High Weald. By the 1st century the wide bay Now partly sheltered by a storm beach shingle spit which gradually developed across the bay and resulted in the deposition of vast quantities of marine and estuarine alluvium (Pevensey Levels Countryside Character Area Description, Low Weald and Pevensey Natural Area).

Bedrock geology

The Levels are dominated by the siltstone, mudstone and sandstone of the Early Cretaceous Hastings Beds, and of Weald Clay, which were raised and exposed in the Tertiary Alpine Orogeny (mountain-building-episode). Small areas of Greensand, Gault, and Chalk can be found in the west of the NCA at the boundary with the South Downs (Pevensey Levels Countryside Character Area Description, Low Weald and Pevensey Natural Area).

Superficial deposits

Marine and freshwater deposits of clays, silts, sands and gravels, laid down behind storm beach shingle spits. Some raised marine deposits were laid down at the western end of the NCA (Pevensey Levels Countryside Character Area Description, Low Weald and Pevensey Natural Area).

Designated geological sites

The NCA includes the following geological sites (Natural England, Geological and Mixed Sites of Special Scientific Interest, 2021):

Soils and Agriculture Classification

The marine and estuarine alluvium sediments have given rise to the present day loamy and clayey soils. Loamy and clayey soils of coastal flats with naturally high groundwater cover 54 per cent of the NCA; with smaller areas of slowly permeable seasonally wet slightly acid but base-rich loamy and clayey soils, slightly acid loamy and clayey soils with impeded drainage and freely draining lime-rich loamy soils (Pevensey Levels Countryside Character Area Description, Natural England, 2010).

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):

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.

Trees and woodlands 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.

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

As per the figures above, the landscape is devoid of significant tree cover. Woodland is restricted to areas of higher ground associated with settlements. Scrub lined ditches occur in areas of the marsh and isolated, windswept trees can also be seen marking the lines of ditches or roads (Pevensey Levels 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

Drainage ditches and banks divide fields, with channels forming barriers to grazing stock, creating a chequer – board pattern. Infrequent hedges and fences line roadways. The estimated boundary length is 412 km. As of 2011, 22 km of ditches were under an Environmental Stewardship ditch boundary option (Natural England, 2010, Pevensey Levels Countryside Character Area description; Countryside Quality Counts, 2003).

Field patterns

The fields of the area are predominantly small and many are highly irregular. This irregular pattern of fields may reflect the piecemeal reclamation (or ‘inning’) of the area. The medieval origin of the field pattern is reflected in the way the 14th century Crooked Ditch follows the irregular boundaries of fields (Pevensey Levels 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

Pevensey Levels represents the largest tract of wetland in east Sussex and is one of the largest and least fragmented lowland wet grassland systems in south-east England. The extensive area of coastal and floodplain grazing marsh covers nearly 40 per cent of the NCA. The low-lying grazing meadows are intersected by a complex system of ditches, often reed fringed which support a variety of important wetland communities, including nationally rare and scarce plants and invertebrates. The wet grassland also supports wintering and breeding bird species. In addition the NCA contains important arable habitats. These support nationally important assemblages of arable birds (JNCC Ramsar Information Sheet: UK11053 2008, Natural England, 2010, Low Weald and Pevensey Natural Area Profile, Natural England 2012)

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

This area Now a shallow bay in the Roman period and within the bay were small islands where the earliest settlements were founded. Occupation and reclamation continued in the Saxon period – the location of settlement being reflected in the use of the place-name ‘eye’ an old English word meaning ‘island’. There is only a thin scattering of farmsteads and no nucleated settlement in the flat marsh area, although there is a greater density of settlement on the slightly higher ground surrounding the levels, such as around Hooe. Eastbourne is the largest settlement within the NCA and there has been significant extension of urban and fringe into peri-urban around Eastbourne (Countryside Quality Counts Draft Historic Profile Pevensey Levels Countryside Character Area description; Countryside Quality Counts, 2003)

Main settlements

The main settlements within Pevensey Levels NCA are: Eastbourne; Westham; Hailsham; Hankham; Pevensey Bay. The total estimated population for this NCA (derived from ONS 2001 census data) is: 100,770 (Pevensey Countryside Character Area description; Countryside Quality Counts, 2003, Natural England, 2012)

Local vernacular and building materials

Traditional buildings have flint or brick walls, with weatherboarding or hung tiles. Plain tiles are commonly used as a roofing material (Pevensey Levels 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

Military coastal defences including Pevensey castle, Napoleonic Redoubt Fortress at Eastbourne and Martello Towers along the coast are prominent historic features. Flood defences and drainage also form a prominent part of the landscape including the 14th century Crooked Ditch and its embankment. Despite these defences the area Now frequently inundation by the sea causing extensive flooding and leading to deserted villages and moated farmsteads. Salt making Now an important industry in the area from the 11th century at least, and the presence of these salt works is recorded in Domesday book. The east of the NCA includes the start of the South Downs and the area around Willingdon Hill is scattered with evidence of human activity from the Neolithic period onwards. The railway encouraged a flourishing tourist industry along the coast during the Victorian period. This is particularly evident at Eastbourne, which still retains many features and its character as a Victorian/Edwardian seafront despite remaining a popular seaside resort today (Draft Historic Profile, Pevensey Levels 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) tranquillity is associated with the large area of grazing marsh away from the urban areas of the NCA, in particular around Eastbourne and on the higher areas of ground.

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 that there has been a decrease in areas considered undisturbed and an increase in urban intrusion. This is likely to reflect the growth of Eastbourne to the West of the area and the expansion of the A27. A breakdown of intrusion values for this NCA is detailed in the table below.

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

Notable trends from the 1960s to 2007 are the increase in land considered as disturbed between the 1960s and 1990s and the steady increase in urban land.
