Prostrate vegetation of ridgetops on acidic (Cooper 1986b) soils. Ecologically and physiognomically similar to 'fellfields' described from other areas. Stands of this association dominate ridgetops on non-calcareous soils and occupy habitat that appears to be snow-free most oftenin winter. Soils are skeletal and acidic (Cooper 1986b).
