Moorland habitats, which are rare globally, are quite common in Wester Ross. The moors are characterised by blanket bogs composed of sphagnum mosses, and host breeding birds such as golden plover, greenshank and dunlin, along with a resident population of red grouse. The summits of Wester Ross host alpine and sub-alpine heaths comprising mosses, liverworts and lichens, and dwarf shrubs such as alpine bearberry, juniper, crowberry, and cowberry. Beinn Eighe is the only known site for the Northern prongwort in the UK, and represents 75 % of the known world population. Bird species in the montane areas of Wester Ross include ptarmigan, dotterel and snow bunting, along with raptor species such as golden eagle and merlin.
