The Dark Peak heathlands, bogs, gritstone edges and acid grasslands contain relatively few species; heather ("Calluna vulgaris"), crowberry ("Empetrum nigrum"), bilberry ("Vaccinium myrtillus") and hare's-tail cotton grass ("Eriophorum vaginatum") dominate the high moors. After decades of decline due to pollution, "Sphagnum" mosses are returning, with species such as "S. cuspidatum" particularly dominant.
