heath or heathland is a shrubland habitat found on mainly infertile acidic soils, characterised by open, low growing woody vegetation, often dominated by plants of the Ericaceae. It is similar to moorland, but is generally warmer and drier.
Heaths are widespread worldwide. They form extensive and highly diverse communities across Australia in humid and sub-humid areas. Fire regimes with recurring burning are required for the maintenance of the heathlands. Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in California, New Caledonia, central Chile and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations across all continents, except Antarctica.
