National scenic areas are primarily designated due to the scenic qualities of an area, however NSAs may well have other special qualities, for example related to culture, history, archaeology, geology or wildlife. Areas with such qualities may be protected via other national and international designations that overlap with the NSA designation. Loch Rannoch and Glen Lyon includes a National nature reserve at Ben Lawers, and there are three Special Areas of Conservation and one Special Protection Area within the NSA.
