Areas of Outstanding Natural Beauty have been designated under the National Parks and Access to the Countryside Act (1949).
- Under the act, the primary purpose of designation is the conservation and enhancement of the natural beauty of the area.
Secondary objectives are:
- To facilitate and enhance public enjoyment, understanding and appreciation of the area.
- To promote sustainable forms of social and economic development that in themselves conserve and enhance the area’s natural beauty.
The Countryside and Rights of Way Act (2000), often know as the CROW Act, gave a legal duty to many public bodies and officers to ‘have regard to’ the purpose of designation of an AONB when undertaking any action that might affect its natural beauty.
