An open habitat characterized by low-growing woody shrubs, particularly heather and related plants, typically found on nutrient-poor, acidic soils. These ecosystems are maintained by periodic disturbances like fire or grazing.
From Old English 'haeth' meaning wasteland or uncultivated ground, combined with 'land.' The word is related to 'heathen,' originally meaning 'dweller on the heath.' The ecological term became precise in the 18th-19th centuries as naturalists studied these distinctive plant communities.
