National scenic area (Scotland)
A national scenic area (NSA) is a conservation designation used in Scotland, and currently administered by Scottish Natural Heritage. NSAs are defined as having outstanding scenic interest or unsurpassed attractiveness.
The primary purpose of the NSA designations is to conserve and enhance the natural beauty of the landscape, in a similar way to the Area of Outstanding Natural Beauty (AONB) designation used elsewhere in the UK.

The National Parks and Access to the Countryside Act 1949 covers England, Wales and Northern Ireland. This act recognises Areas of Outstanding Natural Beauty in areas of countryside with significant landscape value in each of the three nations, that has been specially designated by their administrations.
