There are no conservation designations within the new Knoydart DMG boundary area.
Within West Knoydart DMG the only significant SSSI designated site being the pinewood at Barisdale. There are a number of smaller designated sites, with two loch systems carrying both SSSI and SPA status.
However, landscape designations are very important with the Knoydart National Scenic Area covering part of the two DMGs and the wild land classification covering virtually all of the open ground part of the two groups.
