Moorland is a type of habitat, in the temperate grasslands, savannas, and shrublands biome, found in upland areas, characterised by low-growing vegetation on acidic soils and heavy fog. Most of the world's moorlands are very diverse ecosystems.
Along with heathland, moorland is the most extensive natural vegetation of the British Isles.
Scottish ‘muirs’ are generally heather moors, but will also have extensive covering of grass, cotton-grass, mosses, bracken and under-shrubs such as crowberry. More wet moorland will have sphagnum moss merging into bog-land.
