The Thames Basin Heaths are a natural region in southern England in Berkshire, Hampshire and Surrey, a slightly mottled east-west belt of ecologically recognised and protected land.

Contents

They are recognised as national character area 129 by Natural England, the government's advisor on the natural environment. They cover 118,529 hectares (457.64 sq mi) of countryside. Inset towns include Newbury, Camberley, Ascot and Woking, To the west sit the Berkshire Downs, across similar size, well-drained, and intensively farmed, sports-use or settled Thames floodplains to the north are the similarly protected Chilterns and to the near south are the Hampshire Downs. [1] Not protected as extensively but in significant part adding to the habitats of fauna are the Thames Valley (including Thames Basin lowlands) to the east and as described to the north.

Environment

The terrain of the heathland is characterized by flat or gently sloping plateaux with numerous watercourses incising broad or sometimes steep-sided valleys. Apart from these, the heaths are lower heading east (before the London Basin) and along the main river valleys to the low-lying areas of the Kennet floodplain and lower reaches of the Loddon and its largest tributary, the Blackwater. At the western edge is the chalk scarp of the Hampshire Downs. The highest elevation is 296 metres. [1]

Drainage

The other main watercourses are the Basingstoke Canal, the Kennet & Avon Canal, the Wey, Whitewater, Pang and Mole. [1]

Just over 20,000 hectares (17%) sits in the North Wessex Downs AONB.

The zone has:

There are many Sites of Special Scientific Interest or SSSIs within one of the largest is the Broadmoor to Bagshot Woods and Heaths SSSI where rare types of birds and other species are professionally monitored and conserved.

Much of the east of the zone there can be easily traced a Roman Road, the Devil's Highway (Roman Britain). The region has an Iron Age hillfort, one of several so-named, in this case specifically, Caesar's Camp, Bracknell Forest.

Incursionary barriers

Ecologically near-sterile obstacles to migration, coupled with longstanding biome and habitat loss are significant. Chiefly these are the:

To a lesser extent (the narrower) main routes of rail and road:

No wildlife crossings to abate these obstacles have yet been made.

Kennet and Avon Canal Canal in southern England

The Kennet and Avon Canal is a waterway in southern England with an overall length of 87 miles (140 km), made up of two lengths of navigable river linked by a canal. The name is used to refer to the entire length of the navigation rather than solely to the central canal section. From Bristol to Bath the waterway follows the natural course of the River Avon before the canal links it to the River Kennet at Newbury, and from there to Reading on the River Thames. In all, the waterway incorporates 105 locks.

River Kennet tributary of the River Thames in Southern England

The Kennet is a tributary of the River Thames in Southern England. Most of the river is straddled by the North Wessex Downs AONB. The lower reaches have been made navigable as the Kennet Navigation, which – together with the Avon Navigation, the Kennet and Avon Canal and the Thames – links the cities of Bristol and London.

Chobham Common Location near Chobham, Surrey, of a British tank research centre

Chobham Common is a 655.7-hectare (1,620-acre) biological Site of Special Scientific Interest north of Chobham in Surrey. It is a Nature Conservation Review site, Grade I and a national nature reserve. It is part of the Thames Basin Heaths Special Protection Area and the Thursley, Ash, Pirbright and Chobham Special Area of Conservation. It contains three scheduled monuments. Most of the site is managed by the Surrey Wildlife Trust as the Chobham Common nature reserve, but the SSSI also includes a small private reserve managed by the Trust, Gracious Pond.

River Blackwater (River Loddon) Tributary of the River Loddon in England

The River Blackwater is a tributary of the Loddon in England and sub-tributary of the Thames. It rises at two springs in Rowhill Nature Reserve between Aldershot, Hampshire and Farnham, Surrey. It curves a course north then west to join the Loddon in Swallowfield civil parish, central Berkshire. Part of the river splits Hampshire from Surrey; a smaller part does so as to Hampshire and Berkshire.

Berkshire Downs

The Berkshire Downs are a range of chalk downland hills in southern England, part of the North Wessex Downs Area of Outstanding Natural Beauty. The Berkshire Downs are wholly within the traditional county of Berkshire, although split between the current ceremonial counties of Berkshire and Oxfordshire. The western parts of the downs are also known as the Lambourn Downs.

North Wessex Downs Area of Outstanding Natural Beauty in England

The North Wessex Downs Area of Outstanding Natural Beauty (AONB) is located in the English counties of Berkshire, Hampshire, Oxfordshire and Wiltshire. The name North Wessex Downs is not a traditional one, the area covered being better known by various overlapping local names, including the Berkshire Downs, the North Hampshire Downs, the White Horse Hills, the Lambourn Downs, the Marlborough Downs, the Vale of Pewsey and Savernake Forest.

Beacon Hill, Warnford

Beacon Hill, Warnford is a 46.4-hectare (115-acre) biological Site of Special Scientific Interest west of Warnford in Hampshire. It is a Nature Conservation Review site, and an area of 40.1 hectares is a national nature reserve. There is a round barrow cemetery dating to the Late Neolithic or Bronze Age on the hill, and this is a scheduled monument.

Tentsmuir National Nature Reserve

Tentsmuir National Nature Reserve (NNR) is located southeast of Tayport in Fife, Scotland. The reserve is made up of three parts, encompassing Morton Lochs, Tentsmuir Point and Tayport Heath, and is managed by NatureScot. The different sections of Tentsmuir NNR were originally designated as separate national nature reserves at different times: the Morton Lochs section was designated in 1952; Tentsmuir Point in 1954; and Tayport Heath in 1988. While these discrete sections are distant from one another, they form part of the extensive dune system at Tentsmuir, and in 2003 SNH combined the three sites to form Tentsmuir National Nature Reserve. The adjoining Tentsmuir Forest is managed by Forestry and Land Scotland and covers most of the land between the three portions of the NNR.

Hampshire Downs

The Hampshire Downs form a large area of downland in central, southern England, mainly in the county of Hampshire. They are part of a belt of chalk downland that extends from the South Downs in the southeast, north to the Berkshire and Marlborough Downs, and west to the Dorset Downs.

Dorset Heaths

The Dorset Heaths form an important area of heathland within the Poole Basin in southern England. Much of the area is protected.

The Natural Areas of England are regions, officially designated by Natural England, each with a characteristic association of wildlife and natural features. More formally, they are defined as "biogeographic zones which reflect the geological foundation, the natural systems and processes and the wildlife in different parts of England...".

A National Character Area (NCA) is a natural subdivision of England based on a combination of landscape, biodiversity, geodiversity and economic activity. There are 159 National Character Areas and they follow natural, rather than administrative, boundaries. They are defined by Natural England, the UK government's advisors on the natural environment.
