Explanation

Kwongan is a type of heathland found on the coastal plains of Western Australia. Kwongan comprises floristically-rich heath with dense thickets of sclerophyllous shrubs and isolated small trees. It is characterised by nutrient-poor sandy soils, frequent wildfire, a very high level of endemism, spectacular displays of wildflowers in spring, and a Mediterranean climate with winter rainfall and hot, dry summers.
