The term "Cotswolds National Landscape" was adopted in September 2020, using a proposed name replacement for
Areas of Outstanding Natural Beauty (AONB). All AONBs in England and Wales were re-branded as "National Landscapes" in November 2023, although (as of 2024) the legal name and designation remains "Area of Outstanding Natural Beauty" under the
Countryside and Rights of Way Act 2000, amending the
National Parks and Access to the Countryside Act 1949. The term AONB is still used in this section. The Cotswolds National Landscape area (formerly the Cotwolds AONB) was originally designated as an Area of Outstanding Natural Beauty (AONB) in 1966, with an expansion on 21 December 1990 to . In 1991, all AONBs were measured again using modern methods, and the official area of the Cotswolds AONB was increased to . In 2000, the government confirmed that AONBs have the same landscape quality and status as
National Parks. It is England's third-largest protected landscape, after the
Lake District and
Yorkshire Dales national parks. The Cotswolds National Landscape, which is the largest in
England and Wales, stretches from the border regions of South Warwickshire and Worcestershire, through West Oxfordshire and Gloucestershire, and takes in parts of Wiltshire and of
Bath and North East Somerset in the south. Gloucestershire County Council is responsible for sixty-three per cent of the AONB. The Cotswolds Conservation Board has the task of conserving and enhancing the AONB. Established under statute in 2004 as an independent public body, the Board carries out a range of work from securing funding for 'on the ground' conservation projects, to providing a strategic overview of the area for key decision makers, such as planning officials. The Board is funded by
Natural England and the seventeen local authorities that are covered by the AONB. The Cotswolds AONB Management Plan 2018–2023 was adopted by the Board in September 2018. The landscape of the AONB is varied, including escarpment outliers, escarpments, rolling hills and valleys, enclosed limestone valleys, settled valleys, ironstone hills and valleys, high wolds and high wold valleys, high wold dip-slopes, dip-slope lowland and valleys, a Low limestone plateau, cornbrash lowlands, farmed slopes, a broad floodplain valley, a large pastoral lowland vale, a settled unwooded vale, and an unwooded vale. While the beauty of the Cotswolds AONB is intertwined with that of the villages that seem almost to grow out of the landscape, the Cotswolds were primarily designated an Area of Outstanding Natural Beauty for the rare limestone grassland habitats as well as the old growth
beech woodlands that typify the area. These habitat areas are also the last refuge for many other flora and fauna, with some so endangered that they are protected under the
Wildlife and Countryside Act 1981.
Cleeve Hill, and its associated commons, is a fine example of a limestone grassland and it is one of the few locations where the
Duke of Burgundy butterfly may still be found in abundance. A June 2018 report stated that the AONB receives "23 million visitors a year, the third largest of any protected landscape". Earlier that year, Environment secretary
Michael Gove announced that a panel would be formed to consider making some of the AONBs into National Parks. The review will file its report in 2019. In April 2018, the Cotswolds Conservation Board had written to
Natural England "requesting that consideration be given to making the Cotswolds a National Park", according to Liz Eyre, chairman. This has led to some concern; one member of the
Cotswold District Council said, "National Park designation is a significant step further and raises the prospect of key decision making powers being taken away from democratically elected councillors". In other words, Cotswold District Council would no longer have the authority to grant and refuse housing applications. Indicative of the Cotswolds' uniqueness and value is that five European
Special Areas of Conservation, three
national nature reserves and more than 80
Sites of Special Scientific Interest are within the Cotswolds AONB. The Cotswold Voluntary Wardens Service was established in 1968 to help conserve and enhance the area, and now has more than 300 wardens. The
Cotswold Way is a long-distance footpath, just over long, running the length of the AONB, mainly on the edge of the Cotswold escarpment with views over the
Severn Valley and the Vale of
Evesham. ==Places of interest==
