The designation “Area of Outstanding Natural Beauty” (AONB) aims to conserve and enhance our best national landscapes, whilst recognising the needs of the local community and economy.
Natural England is responsible for designating AONBs and advising Government and others on how they should be protected and managed. Although ‘natural beauty’ is enshrined in the title, in essence most AONBs represent rich cultural landscapes.
The 1949 National Parks and Access to the Countryside Act defines “natural beauty” as “including the preservation or, as the case may be, the conservation of its flora, fauna and geological or physiographical features”. The conservation of archaeological, architectural and vernacular features in the landscape is implicit as landscape is human-made and cultural.
What is an AONB?
Areas of Outstanding Natural Beauty (AONBs) are designated under the Countryside & Rights of Way Act (2000), and along with National Parks they represent the finest examples of countryside in England and Wales. Designation seeks to conserve and enhance natural beauty; including flora and fauna, geology and landscape features, archaeology and architecture; whilst recognising the needs of the local community and economy.
