Erica tetralix
The extensive areas of dry heath are dominated by ling ("Calluna vulgaris"), bell heather ("Erica cinerea") and dwarf gorse ("Ulex minor"). Important lichen communities include "Pycnothelia papillaria". Common bracken ("Pteridium aquilinum") is dominant over large areas. On the damper heath, cross-leaved heath ("Erica tetralix") becomes dominant with deer-grass ("Trichophorum cespitosum". The heath and bracken communities form a mosaic with acid grassland dominated by purple moor-grass ("Molinia caerulea") mingled with many specialised heathland plants such as petty whin ("Genista anglica"), creeping willow ("Salicaceae" sp.) and heath spotted orchid ("Dactylorhiza maculata").
