This is the most natural and species rich habitat in Scotstown Moor, supporting plant species now rare in north-east Scotland. The bogs and flushes occur mainly in the southern half of Scotstown moor, although there is a pond in the north-west corner of the site, and a small acid bog in the eastern part of the conifer plantation. Some of the more unusual bog plants include bogbean ("Menyanthes trifoliata"), grass of parnassus ("Parnassia palustris"), northern marsh orchid ("Dactylorhiza purpurella"), lesser butterfly orchid ("Platanthera bifolia"), common butterwort ("Pinquicula vulgaris"), round-leaved sundew ("Drosera rotundifolia") and black-bog rush ("Schoenus nigricans").
