Upland heathland is dominated by stands of dwarf shrubs. Dry and wet Upland heathland also include a sparse array of other species such as grasses, sedges and their allies, and herbs. Upland heathland is the characteristic vegetation of podsolised, free-draining, acid mineral soils and also shallow peat up to about 50 cm deep. The habitat is widespread as secondary vegetation in the cool, wet climate of the uplands, where it generally occupies land which was once woodland. It is common throughout the uplands of Scotland, from a few metres above sea level to over 600 m in the eastern Highlands.
