Common Heather
Calluna vulgaris
Common Heather is a perennial, evergreen dwarf shrub that prefers lime-free soils. It forms dense stands in heaths, moors, and open woodlands. Characterized by scale-like leaves and bell-shaped, mostly purple flowers, it plays a central role in the ecology of European heathlands.
Details
Habitat function
Important food source for specialized insects; cover and nesting site for ground-nesting birds such as the woodlark.
Nutrient uptake
Very efficient nutrient uptake at low availability through symbiosis with mycorrhizal fungi.
Food source for
Honey bees, heather bee (Colletes succinctus), caterpillars of numerous butterfly species (e.g., common heath moth), Heidschnucken sheep.
Human use
Production of heather honey, medicinal plant (tea for urinary tract complaints), broom making (historically), ornamental plant in horticulture.
Ecology
Ecological role
Pioneer plant on acidic soils; keystone species for biodiversity in heathland landscapes.
Competitor species
Wavy hair-grass (Avenella flexuosa), bracken (Pteridium aquilinum), various birch species.
Ecosystem service
Soil stabilization, carbon sequestration in organic horizons, provision of nectar for beekeeping.
Threats
Atmospheric nitrogen deposition (eutrophication), scrub encroachment due to lack of management/grazing, land conversion.
Scientific profile
Profile
Reproduction
Generative via long-lived seeds (soil seed bank), with germination often stimulated by heat (fire); vegetative via layering of prostrate branches.
Protection & threats
Main threats
Eutrophication via atmospheric nitrogen deposition (leading to grass encroachment), lack of management (succession to woodland), habitat fragmentation, and drainage of bogs.
