Birak is the Noongar season of fire, when the easterly morning breezes and westerly afternoon breezes helped control mosaic burning. The fires would flush out game for food and control weeds to allow for new growth of edible plants.

Flowering plants on show during Birak include marri trees and red flowering gums, the verticordias and some mallees, as well as the vibrant orange-flowering West Australian Christmas Tree. Join a Guided Walk to see these plants in the Botanic Garden or ask in the Visitor Information Centre where you can find them.

Birds are leaving their nests and mammals are growing and would traditionally be a good source of bushtucker.
